[openstack-dev] [tc][fuel] Making Fuel a hosted project

2017-06-21 Thread Vladimir Kuklin
Folks, I sent a reply a couple of days ago, but somehow it got lost. The
original message goes below

Folks

It is essentially true that Fuel is no longer being developed as almost 99%
of people have left the project and are working on something else. May be,
in the future, when the dust settles, we can resume working on it, but the
probability is not so high as of now.

I would like to thank everyone who worked on the project - contributors,
reviewers, core-reviewers, ex-PTLs Alex Shtokolov, Vladimir Kozhukalov and
Dmitry Borodaenko - it was a pleasure to work with you guys.

Also, I would like to thank puppet-openstack project team as we worked
together on many things really effectively and wish them good luck as well.

Special Kudos to Jay and Dims as they helped as a lot on governance and
community side.

I hope, we will work some day together again.

At the same time, I would like to mention that Fuel is still being actively
used and some bugs are still being fixed, so I would suggest, if that is
possible, that we keep the github repository available for a while, so that
those guys can still access the repositories.

Having that said, I do not have any other objections on making Fuel Hosted
project.


Yours Faithfully

Thank you for keeping the hand on the pulse.

I am going to take over the PTL duties and we are going to produce releases
according to the wiki
<https://wiki.openstack.org/wiki/Fuel/Release_Schedule>. We are going to
have RC1 next week (around Feb 15). After that we are going to proceed as
planned for March 6th Ocata release.

[openstack-dev] [fuel][tripleo] Fuel and TripleO Cross-Project Integration

2016-11-09 Thread Vladimir Kuklin
Stackers

During OpenStack summit in Barcelona we had a rather productive
cross-project integration session between Fuel and TripleO projects [0].
More precisely we discussed the following:

1. Services composition and deployment workflow control
2. Complex networking configuration (bonds, offloading, etc.)
3. Post-deployment cluster management, i.e. day-2 operations
4. Approaches to reference architecture recomposition, e.g. in-flight
database vertical scaling
5. Upgrades
6. Provisioning and disks partitioning

The most interesting part of integration would be to consider integration
of deployment and post-deployment orchestration approaches and services
composition. The further steps are to start working on:

1. Cross-project specification on workflow management, e.g. for upgrades
and day-2 operations
2. Look into possibility of Mistral integration as a workflow execution
tool within the designed model
3. Consider integration of Fuel provisioning, network configuration and
disk partitioning with Ironic and TripleO

[0] https://etherpad.openstack.org/p/fuel-ocata-fuel-tripleo-integration

I would suggest that we add discussing this into TripleO or Fuel IRC
meeting agenda next week.

Please let me know what are you thoughts on this.

Re: [openstack-dev] [Fuel][Plugins] Contributing a new fuel-plugin

2016-10-19 Thread Vladimir Kuklin
Hi Omar

You might want to follow basic OpenStack documentation here:
http://docs.openstack.org/infra/manual/creators.html if you want to create
a new project. For fuel plugins just put it into fuel namespace and call it
something like 'fuel-plugin-'.

If you want to contribute to the existing plugin, please use its respective
launchpad project.

Please let me know if you need any other help.

Re: [openstack-dev] [Fuel] Mitaka stable branch

2016-07-13 Thread Vladimir Kuklin
Bogdan, Vladimir

*Regarding upgrades of Fuel Master Node and environments. *

First, regarding Fuel Master Node upgrades and enablement of usage of 9.0
LCM features with older clusters. It is assumed that we test usability of
Fuel Mitaka code with already deployed clusters, e.g. 8.0, 7.0 and so on.
Whenever an issue arise, we fix it. This would allow us to reuse newest
features to be able to enable LCM and newest orchestration and integration
capabilities with older clusters by essentially, calling old serializers
code within extensions pipeline, applying some pre- and postprocessing to
the serialized data. Here is an example of how it is done (Work in
progress):

https://review.openstack.org/#/c/333845/

This is an extension that first runs new LCM serializer which data is not
compatible with 9.0, but part of which we need for LCM engine (e.g.
'cluster context'), then we simply run 8.0 Serializer, add cluster info
into serialized data and then we just update 'upload_configuration' and
related tasks by simply copying them from Mitaka code of Fuel Library. I
proof-tested this by adding Sahara into already installed 8.0 cluster with
BVT scenario and it seems to be working.

*Regarding environments upgrades*

Having completed item #1 we should be able to run new orchestration against
old clusters, so that we can upgrade environments to newer versions,
esentially, by rolling reinstallation of control plane and resource nodes,
which means that as soon as new version of installed software (including
OpenStack, LMA toolchaing and other stuff) works fine with the feature-set
specified within the old cluster configuration, it should be OK to do so,
but this basically becomes a matter of building consistent upgrade path for
the particular environment.

*Conclusion*

Let's add bugfixing for management of old clusters and pre-9.0 clusters LCM
support into our RoadMap and we should be safe to go.

Re: [openstack-dev] [Fuel] Failed to install fuel master

2016-07-05 Thread Vladimir Kuklin
Hi, Alioune

Let's start with the most basic steps. Which Fuel are you using?
And how do you install the node? Do you use USB stick or DVD or some IPMI
virtual media? From what I see here it pretty much looks like, that this
media is not inserted into the host.

+1 to initial suggestion, but I guess we need to have a full feature

 Dear colleagues,

 I'd like to request workrooms sessions swap.

 We have a session about Fuel/Ironic integration and I'd like
 this session not to overlap with Ironic sessions, so Ironic
 team could attend Fuel sessions. At the same time, we have
 a session about orchestration engine and it would be great to
 invite there people from Mistral and Heat.

 My suggestion is as follows:

 Wed:
 9:50 Astute -> Mistral/Heat/???
 Thu:
 9.00 Fuel/Ironic/Ironic-inspector

 If there are any objections, please let me know asap.

It seems that Nailgun has not started. Could you please provide us with the
version of Fuel you are using? You can find logs for nailgun in:

for <9.0/pre-Mitaka versions
/var/log//nailgun/

Re: [openstack-dev] [Fuel] Getting rid of cluster status

2016-03-16 Thread Vladimir Kuklin
Folks

As I generally support the idea of getting rid of cluster status, this
requires thorough design. My opinion here is that we should leave it as a
function of nodes state until we come up with a variant of better
calculation of cluster status. Nevertheless it is true that cluster status
is actually a function of other primary data and should be calculated on
the client side. I suggest that we move towards more fine-grained
component-based architecture (simplest example is OpenStack Fuel vs
non-OpenStack Fuel) and figure out a way of calculating each component's
status. Then we should calculate each component's status and then a cluster
status should be an aggregate of those. For example, we could say that the
only components we have right now are nodes and the aggregate is based on
the nodes status and whether they are critical or not.

Re: [openstack-dev] [Fuel] Trouble mapping the Remote PXE node

2016-03-11 Thread Vladimir Kuklin
Hi, Akshik

Thanks for the email. Do you have nailgun logs with you? I guess, it would
much more easier to debug this while having more diagnostic info. Please,
file a bug at launchpad following the steps described here:

https://wiki.openstack.org/wiki/Fuel/How_to_contribute#Bugs

then post the link to this thread. The diagnostic snapshot would give us
more info on your environment configuration along with logs of Nailgun.

Feel free to contact us again whether you face any issues filing the bug.

Re: [openstack-dev] [Fuel] [FFE] Unlock Settings Tab

2016-03-02 Thread Vladimir Kuklin
Vitaly

Thanks for bringing this up. Actually the spec has been on review for
almost 2 weeks: https://review.openstack.org/#/c/282695/. Essentially, this
is not introducing new DSL but replacing the existing one with more
powerful extendable language which is being actively developed within
OpenStack and is already a part of other projects (Murano, Mistral), which
has much more contributors, can return not only boolean but any arbitrary
collections. So it means that we want to deprecate current Expression
language that you wrote and replace it with YAQL due to those reasons. You
are not going to extend this Expression-based language in 3 weeks up to
level of support of extensions, method overloading, return of arbitrary
collections (e.g. we also want to calculate cross-depends and requires
fields on the fly which require for it to return list of dicts) and support
of this stuff on your own, are you?

First of all, if you read my email again, you will see that I propose a way
of tracking upstream in less continuous mode with nightly testing and
switching to it based on automated integration testing which will leave us
0 opportunity to face the aforementioned issues.

This is not true. We can run FUEL CI against any set of commits.

Dmitry, could you please point me at the person who will be strictly
responsible for creating this 'ketchup' commit? Do you know that this may
take up the whole day (couple of hours to do RCA, couple of hours on
writing and debugging and couple of hours for FUEL CI tests run) and block
the entire Fuel project from having ANY code merged? Taking into
consideration that openstack infra is currently under really high load it
may take even several days for the fix to land into master. How do you
expect us to have any feature merged prior to FF?

I have always thought that buliding software is about verification being
more important than 'trust'. There should not be any humanitarian stuff
invloved - we are not in a relationship with Puppet-OpenStack folks,
although I really admire their work very much. We should not follow sliding
git references without being 100% sure that we have mutual gating of the
code.

Moreover, having such git ref as a source in our Puppetfile will lead to
the situation when we have UNREPRODUCIBLE build of Fuel project. Each build
may and will result in different code and you will not be able to tell
which one without actually looking into the build logs. I think, that this
is unacceptable as it may lead to impossibilty of debugging and
troubleshooting of anything because it will be impossible to reproduce
things.

Additionally, we do not have:

1) depends-on support
2) any process instantiated for monitoring of the Puppet-Openstack FUEL CI
job
3) any person responsible for monitoring of that job

Finally, we have another blocker issue [0] which essentially killed March
1st in EU timezone from code merge point of view as our master is blocked
right now by non-boostrapping master node.

Having that said I propose that we:

1) immediately pick a set of stable commits to puppet-openstck
2) immediately update puppetfile  with this set
3) unblock other fuel developers
4) fix the aforementioned issues
5) turn tracking of upstream commits on when we have all the pieces set up
and when we are sure that we will not ever break master with this change.

Re: [openstack-dev] [Fuel][Fuel-Library] Fuel CI issues

2016-02-29 Thread Vladimir Kuklin
Hi Ivan

Thanks for bringing this up. Frankly, I think that we hurried a little bit
by making our integration with upstream puppet manifests too continuous. I
would suppose that we used a little bit different technique.

First of all, we need to have a set of stable Fuel commits against which
the changes to upstream manifests should be tested. Could you please
elaborate on whether we are doing this already?

Secondly, we need to have FUEL CI working with a set of stable commits of
puppet openstack manifests which passed those upstream tests as we should
not have too much moving parts or we will get into situation similar to
requirements.txt updates when we have pypi updated with new library, e.g.
oslo-serialization.

In this case, we will be able to do proper testing against frozen code-base
for each piece thus avoiding such issues while retaining fair amount of
integration with upstream puppet manifests for OpenStack.

So what do you think?

[openstack-dev] [Fuel][Fuel-Library] Nominating Matthew Mosesohn for Fuel Library Core

2016-02-24 Thread Vladimir Kuklin
Fellow Fuelers

I would like to kindly ask you to consider voting for Matthew Mosesohn as a
Fuel Library Core
reviewer.

Matthew has been working with Fuel since its inception, worked on countless
amount of features, such as :

Master Node Upgrades and Backup
Improvements to Fuel Infra
Mitaka, Kilo and Juno Support
Detachable Services Plugins
RHOS Support in Fuel
UCA Support
Refactoring of Haproxy and Firewall pieces

He has also been known as our Fuel Master node and Docker guru and has been
continuously working on bugfixing where he scores as a bug squashing
monster with more than 150 bugfixes to all the parts of Fuel Library (#1
throughout FL history).

As you can see, there is not a piece of Fuel Library that he has not yet
gained experience with.

And this can easily be fetched with simple statistics of Matt's
contribution. He is the topmost contributor to all Fuel projects among all
Fuel Library folks and is the 3rd contributor of Fuel Library.
He also reviews a lot and has a fair amount of -1's (he is not as cruel as
me, though :-))

Having that said, I would like to open the vote to promote Matt to
OpenStack Fuel Library core reviewers.

Re: [openstack-dev] [fuel] Merge freeze for CI switch to Mitaka

2016-02-17 Thread Vladimir Kuklin
Folks

First of all, there is a critical bug which is not fixed.  It may be
floating because it is related to implicit resources ordering in puppet.
But it does not mean that it is not a merge blocker.

Secondly, I do not share your optimism about easiness of bugfixing of
possible regressions because I do not see results of more complete testing
of such changes.

Additionally, there was no preliminary discussion about this change. You
did not give us enough time to express our opinion. For example, the
original email was sent after 8pm msk and I had already left the office.

Finally goes my constructive proposal.

1) merge the fix https://review.openstack.org/281440
2) get several consecutive green bvts
3) in meantime drag this mitaka iso through swarm
4) compare the results and merge mitaka iso on Saturday if no criticals are
found. Saturday is a working day in Russia, so there will be low dev
activity and we will be able to control the swarm run.

[openstack-dev] [Fuel][Puppet] New Rspec Noop Tests Matcher to Ensure Transitive Dependencies

2016-02-17 Thread Vladimir Kuklin
Fuelers

It seems that this change [0] into Fuel came unnoticed, but it may help you
in testing your puppet catalogues.

I was refactoring our code pieces that actually wait for Load Balancer to
be ready to serve requests. I ended putting things into a special define
called `wait_for_backend`. This broke direct dependencies between resources
as there was only transitive order between them (e.g. A->B->C) instead of
direct (A->C). And this broke our noop tests as they were expecting to see
the latter ordering. This in turn required me to write an additional
matcher based on puppet source code.

[0] https://review.openstack.org/#/c/272702/

Here is an example of the code you might want to use in your rspecs:

`expect(graph).to
ensure_transitive_dependency("Class[openstack::galera::status]",
"Haproxy_backend_status[mysql]")`
graph is lazy calculated within noop tests shared_examples.

So, if you need to just check if one resource will execute after the
another, you do not need 'that_comes_[before|after]' anymore.

Puppeters

Folks, this may be also interesting for you.

Re: [openstack-dev] [Fuel] [Fuel UI] Node role list grouping

2016-01-29 Thread Vladimir Kuklin
Sergii

I disagree with you here a little bit. Role abstraction is a useful thing
from high-level standpoint. I would suggest that this list of roles
grouping, e.g. which roles are mandatory and which are configured within
which group can be specified:

1) in global settings of Nailgun
2) per-plugin
3) per environment in UI

This should cover all the cases even for very flexible roles allocation.

Re: [openstack-dev] [Fuel] Proposal to Delay Docker Removal From Fuel Master Node

2015-12-16 Thread Vladimir Kuklin
Vladimir

I am pretty much for removing docker, but I do not think that we should
startle our developers/QA folks with additional efforts on fixing 2
different environments. Let's just think from the point of development
velocity here and at delay such changes for at least after NY. Because if
we do it immediately after SCF there will be a whole bunch of holidays and
Russian holidays are Jan 1st-10th and you (who is the SME for docker
removal) will be offline. Do you really want to fix things instead of
enjoying holidays?

[openstack-dev] [Fuel] Proposal to Delay Docker Removal From Fuel Master Node

2015-12-15 Thread Vladimir Kuklin
Folks

This email is a proposal to push Docker containers removal from the master
node to the date beyond 8.0 HCF.

Here is why I propose to do so.

Removal of Docker is a rather invasive change and may introduce a lot of
regressions. It is well may affect how bugs are fixed - we might have 2
ways of fixing them, while during SCF of 8.0 this may affect velocity of
bug fixing as you need to fix bugs in master prior to fixing them in stable
branches. This actually may significantly increase our bugfixing pace and
put 8.0 GA release on risk.

Re: [openstack-dev] [Fuel] PostgreSQL 9.3 and JSON operations

2015-12-15 Thread Vladimir Kuklin
Folks

Let me add my 2c here.

I am for using Postgres 9.3. Here is an additional argument to the ones
provided by Artem, Aleksandra and others.

Fuel is being sometimes highly customized by our users for their specific
needs. It has been Postgres 9.3 for a while and they might have as well
gotten used to it and assumed by default that this would not change. So
some of their respective features they are developing for their own sake
may depend on Postgres 9.3 and we will never be able to tell the fraction
of such use cases. Moreover, downgrading DBMS version of Fuel should be
inevitably considered as a 'deprecation' of some features our software
suite is providing to our users. This actually means that we MUST provide
our users with a warning and deprecation period to allow them to adjust to
these changes. Obviously, accidental change of Postgres version does not
follow such a policy in any way. So I see no other ways except for getting
back to Postgres 9.3.

Sorry, this vote is irrelevant as it is not about all the concerns rasied

[openstack-dev] [Fuel] Experimental Task Based Deployment Landed into Master

2015-12-11 Thread Vladimir Kuklin
Fuelers

I am thrilled to announce that task based deployment engine [0] has been
just merged into Fuel master. We checked it against existing BVT test cases
for regressions as well as against functional testing for several cases of
deployment. All the OSTF and network verification tests have successfully
passed.

We will obviously need to polish it and fix bugs which will arise, but this
is a gigantic step forward for our orchestration engine which should allow
us to drastically increase our development velocity as well as end user
experience.

Thanks to all who participated in development testing and review:

Dmitry Ilyin
Vladimir Sharshov
Bulat Gaifullin
Alexey Shtokolov
Igor Kalnitsky
Evgeniy Li
Sergii Golovatiuk
Dmitry Shulyak

and many-many others

I am pretty confident that this will allow us to develop and test faster as
well as introduce support of some of Life-Cycle Management scenarios in 8.0
release.

Once again, thank you all, folks, for your dedicated work and efforts on
making Fuel better.

[openstack-dev] [Fuel] Feature Freeze Exception Request: Task Based Deployment in Astute

2015-12-01 Thread Vladimir Kuklin
sed approach allows one to deploy things with separate services in
much more flexible ways. E.g one will not have to introduce 2 roles in the
plugin for controller to detach keystone services, e.g.
pre-keystone-controller-tasks and post-keystone-controller-tasks. All he
will need is to introduce "skipped" keystone task for controllers so that
keystone is deployed only on the node with keystone role.

** Merge plan*

Merge Astute changes - ETA Dec 4rd
Merge Nailgun changes - ETA Dec 4rd
Prepare Fuel Library changes - ETA Dec 3rd
Test this feature on Scale Lab and against swarm - ETA SCF
Make decision whether to enable task-based deployment engine by default -
SCF

** Summary*

This feature brings a lot of benefits for everyone. Its current
implementation introduces 0 chances for regressions as it will be disabled
by default and it will require specific actions for a user to start using
this feature. In meanwhile we will test this feature at Scale Lab and
against swarm and custom tests. And by SCF we may decide whether to switch
to it based on the reported results. If it happens before SCF, we will be
able to significantly ramp up our development and bugfixing velocity.

Re: [openstack-dev] [Fuel] Getting rid of Docker containers on the Fuel master node

2015-11-19 Thread Vladimir Kuklin
Vladimir

Although I am a big fan of this idea, I think it is too risky to do this
during our latest iteration for 8.0 release. There is a lot of stuff that
relies on our containerised approach. For example, it is our Fuel CI
master-node tests which will require adjustments. There are pieces of
things related to infrastructure for update repositories delivery and so on
and so forth. I would assess the risk of this change to break things and
block everything as high. So far, I suggest that if we provide a clear
deadline when such changes can get into master branch. I think, that we
should have all the code including CI jobs in place by Nov 30. Remember -
if CI is broken, our feature freeze is also broken. So I would suggest to
have a couple of days in advance before feature freeze to revert things.

Re: [openstack-dev] [Fuel] HA cluster disk monitoring, failover and recovery

Folks

Is not it possible for an OCF script to clear this attribute after a
sufficient period of successful monitoring of node health? It could be a
better approach in this case then restarting the node.

Re: [openstack-dev] [Fuel] HA cluster disk monitoring, failover and recovery

2015-11-17 Thread Vladimir Kuklin
Bogdan

I think we should firstly check whether attribute deletion leads to node
starting its services or not. From what I read in the official Pacemaker
documentation, it should work out of the box without the need to restart
the node.
And by the way the quote above mentions 'use ONE of the following methods'
meaning that we could actually use attribute deletion. The 2nd and the 3rd
options do the same - they clear short-living node attribute. So we need to
figure out why OCF script does not update the corresponding attribute by
itself.

Re: [openstack-dev] [Openstack-operators] Mirantis Fuel Multi-Region

2015-11-17 Thread Vladimir Kuklin
Hi Folks

Let me comment on a couple of things. Multiregion support is possible from
deployment side. You need to pass a region parameter to corresponding nodes
being deployed.
It is a part of detached services feature which is delivered through
plugins: "
http://specs.fuel-infra.org/fuel-specs-master/specs/7.0/separate-services.html
"
Please look into this change:
https://review.openstack.org/#/c/191244/

It should allow you to set Region name per-node. You will need just to
download nodes settings and add a corresponding parameter 'region' into
deployment yaml files. This will lead for controllers (or corresponding
nodes roles whether you choos to use separated controller services) to
create endpoints with corresponding region name.
Should you face any issues, please create a bug at Launchpad or contact us
within openstack-dev mailing list with [Fuel] tag in the message or
approach us at #fuel-dev IRC channel.

And another comment regarding multirack installation. In 8.0 we are
planning to enable multiple rack configuration MVP to allow users to be
able to deploy across multiple L2 segments for admin network. Please refer
to https://blueprints.launchpad.net/fuel/+spec/l3-multiple-racks .

Re: [openstack-dev] [Fuel] API services available on public VIP

I think, the answer is realtively simple - if user does not want to expose
those APIs, he can easily configure his infra to filter this traffic. We
just need to mention this in Ops Guide.

Re: [openstack-dev] [HA][RabbitMQ][messaging][Pacemaker][operators] Improved OCF resource agent for dynamic active-active mirrored clustering

2015-11-12 Thread Vladimir Kuklin
Hi, Andrew

Thanks for a quick turnaround.

> The one I linked to in my original reply does:

https://github.com/ClusterLabs/resource-agents/blob/master/heartbeat/rabbitmq-cluster

I do not have logs of testing of this script. Maybe, Bogdan has something
to tell about results of testing this script. From the first glance it does
not contain gigantic amount of workarounds we injected into our script to
handle various situations when a node fails to join or tries  to join a
cluster that does not want to accept it (in this case you need to kick it
from the cluster with forget_cluster_node and it starts an RPC multicall in
rabbitmq internals to all cluster nodes, including the dead one, hanging
forever). Actually, we started a long time ago with an approach similar to
the one in the script above, but we faced a lot of issues in the case when
a node tries to join a cluster after a dirty failover or a long time of
being out of the cluster. I do not have all the logs of which particular
cases we were handling while introducing that additional logic (it was an
agile process, if you know what I mean :-) ), but we finally came up with
this almost 2K lines code script. We are actively communicating with
Pivotal folks on improving methods of monitoring RabbitMQ cluster nodes or
even switching to RabbitMQ clusterer+autocluster plugins and writing new
smaleer and fancier OCF script, but this is only in plans for further Fuel
releases, I guess.

restart http://bugs.clusterlabs.org/show_bug.cgi?id=5243) .

Regarding this bug - it was very easy to reproduce - just add additional
check to 'Dummy' resource with non-intersecting interval returning
ERR_GENERIC code and the default check returning SUCCESS code. You will
find that it is restarting only after 2 consequent failures of non-zero
level check.

Regarding other scripts - I am not aware of any other scripts that actually
handle cloned rabbitmq server. I may be mistaking, of course. So if you are
aware if these scripts succeed in creating rabbitmq cluster which actually
survives 1-node or all-node failure scenarios and reassembles the cluster
automatically - please, let us know.

Yes, we are relying on subsequent monitor operations. We also have several
OCF check levels to catch a case when one node does not have rabbitmq
application started properly (btw, there was a strange bug that we had to
wait for several non-zero checks to fail to get the resource to restart
http://bugs.clusterlabs.org/show_bug.cgi?id=5243) . I now remember, why we
did notify errors - for error logging, I guess.

Re: [openstack-dev] [Fuel][Fuel-QA][Fuel-TechDebt] Code Quality: Do Not Hardcode - Fix Things Instead

2015-11-11 Thread Vladimir Kuklin
Matthew

Thanks for your feedback. Could you please elaborate more on the statistics
of such tech-debt eliminations? My perception is that such bugs do not ever
get fixed actually jeopardizing our efforts on bugfixing and actually
making our statistics manupilative.

So far my suggestion is the following - if you can, please do not introduce
workarounds. If you have - introduce a TODO/FIXME comment for it in the
code and create a tech-debt bug. If you see something of that kind that is
already there and does not have such a comment - add this TODO/FIXME and
create a tech-debt bug.

So this is a best effort initiative, but I would encourage core reviewers
to be stricter with such workarounds and hacks - please, do not get them
pass through your hands unless there is a really good reason to merge this
code with these hacks right now.

Re: [openstack-dev] [Fuel][fuel] How can I install Redhat-OSP using Fuel

2015-11-11 Thread Vladimir Kuklin
Hi, Fei

It seems you will need to do several things with Fuel - create a new
release, associate your cluster with it when creating it and provide paths
to corresponding repositories with packages. Also, you will need to create
a base image for Image-based provisioning. I am not sure we have all the
100% of the code that supports it, but it should be possible to do so with
some additional efforts. Let me specifically refer to Fuel Agent team who
are working on Image-Based Provisioning and Nailgun folks who should help
you with figuring out patterns for repositories URLs configuration.

[openstack-dev] [Fuel][Fuel-QA][Fuel-TechDebt] Code Quality: Do Not Hardcode - Fix Things Instead

2015-11-10 Thread Vladimir Kuklin
Folks

I wanted to raise awareness about one of the things I captured while doing
reviews recently - we are sacrificing quality to bugfixing and feature
development velocity, essentially moving from one heap to another - from
bugs/features to 'tech-debt' bugs.

I understand that we all have deadlines and need to meet them. But, folks,
let's create the following policy:

1) do not introduce hacks/workarounds/kludges if it is possible.
2) while fixing things if you have a hack/workaround/kludge that you need
to work with - think of removing it instead of enhancing and extending it.
If it is possible - fix it. Do not let our technical debt grow.
3) if there is no way to avoid kludge addition/enhancing, if there is no
way to remove it - please, add a 'TODO/FIXME' line above it, so that we can
collect them in the future and fix them gradually.

I suggest to add this requirement into code-review policy.

What do you think about this?

I am not sure you addressed me, but, anyway, - yes, we will have a
situation with old containers on new host node. This will be identical to
old host node from database migration point of view.

Re: [openstack-dev] [fuel] Using upstream packages & modules

2015-11-10 Thread Vladimir Kuklin
Alex

Thanks for your very detailed answer - it clarified things a bit. So, if
you would allow me to rephrase it - you are actually conducting a research
on what is the actual gap between our downstream/fork and upstream
UCA/puppet-openstack. This seems to be a very promising initiative. Are you
going to come up with some external-user readable report soon?

Also, regarding multiple distros support.  I think, we need to come up with
an approach of making 'release manager' piece of Nailgun data driven and
just allow a user to run any distribution he or she wants. Just register a
set of repos with packages and run it. Actually, we already have it - we
need to make base-image generation for RPM more flexible and any RPM/DEB
based distro should work ok with it.

The remaining piece is to actually support distro-specific things, e.g.
CentOS/RHEL networking configuration, e.g. l23 network stored config puppet
providers. But this is a distro-supporter/community burden.

These are awesome news.

BTW, why should we enable unit tests for Fuel Library in voting mode right
now? It seems not all our modules have them passing. Can we wait a bit and

Oleg, I actually meant that we do it in the following stages:

1) Change stuff in any amount of business logic engines you want,
configuration databases, wikipedia, 4chan, etc.
2) Schedule a transaction of deployment
3) Make 'transformers/serializers' for each of the task collect all the
data and store them before execution is started
4) Allow user to compare differences and decide whether he actually wants
to apply this change
5) Commit the deployment - run particular tasks with particular set of
settings which are staged and frozen (otherwise it will be impossible to
 debug this stuff)
6) If there is lack of data for some task, e.g. you need some entitties to
be created during the deployment so that other task will use their output
or side-effects to calculate things - this task should not be executed
within this transaction. This means that the whole deployment should be
splitted into 2 transactions. I can mention an old story here - when we
were running puppet we needed to create some stuff for neutron knowing ID
of the network that had been created by another resource 5 seconds earlier.
But we could not do this because puppet 'freezes' the input provided with
"facts" before this transaction runs. This is exactly the same usecase.

So these 6 items actually mean:

1) Clear separation between layers of the system and their functional
boundaries
2) Minimum of cross-dependencies between component data - e.g. deployment
tasks should not ever produce anything that is then stored in the storage.
Instead, you should have an API that provides you with data which is the
result of deployment run. E.g. if you need to create a user in LDAP and you
need this user's ID for some reason, your deployment task should create
this user and, instead of returning this output to the storage, you just
run another transaction and the task that requires this ID fetches it from
LDAP.

Re: [openstack-dev] [Fuel][Fuel-Modularization] Proposal on Decoupling Serializers from Nailgun

2015-10-22 Thread Vladimir Kuklin
Oleg

Thank you for your feedback. IMO, the schema you are providing is very
complex and would surely benefit from some examples.

If I understand correctly your proposal, you are trying to do the things
that we actually want to get rid of - tight coupling and schema control of
data that is being used by components. There should be no cross-reference
between components that do actual deployment. Instead, there should be a
clear separation between layers of our deployment system.

All the data that is provided to deployment (or
provisioning/power_management/etc.) tasks should be accessible through API
of the top-level components such as
Network/Partitioning/IPAddressAllocation/ Manager or any other type of
external configuration database such as ENC of external puppet
master/LDAP/.

 Each task can use some code to transform this output to the representation
that is actually needed for this particular task. Whenever a task
transforms this data it can access API and do version negotiation, for
example. Each time this transformation is performed this task can return
the data to some storage that will save this data for sake of control and
troubleshooting, such as, for example, user can always see which changes
are going to be applied and decide what to do next.

Also, this means that the process of data calculation itself is very 'lazy'
or 'delayed', i. e. the data itself is calculated right at the beginning of
deployment transaction, so that it is not locked to some particular details
of deployment engine data processing and not prone to issues like 'oh, I
cannot get VIP because it has not been allocated yet by Nailgun/oh, I
cannot set it because it has already been set by Nailgun and there is no
way to alter it'.

[openstack-dev] [Fuel][Fuel-Modularization] Proposal on Decoupling Serializers from Nailgun

2015-10-16 Thread Vladimir Kuklin
Hey, Fuelers

TL;DR This email is about how to make

* Intro
I want to bring up one of the important topics on how to make Fuel more
flexible. Some of you know that we have been discussing means of doing this
internally and now it is time to share these thoughts with all of you.

As you could know per Evgeniy Li's message [0] we are looking forward
splitting Fuel (specifically it's Fuel-Web) part into set of microservices
each one serving their own purpose like networking configuration,
partitioning, etc.


And while we are working on this it seems that we need to get rid of
so-called Nailgun serializers that are put too close to business logic
engine, that have a lot of duplicating attributes; you are not able to
easily modify or extend them; you are not able to change their behaviour
even when Fuel Library is capable of doing so - everything is hardcoded in
Nailgun code without clear separation between business logic and actual
deployment workflow data generation and orchestration.

Let me give you an example:

* Case A. Replace Linux bridges with OVS bridges by default

We all know that we removed OVS as much as possible from our reference
architecture due to its buginess. Imagine a situation when someone
magically fixed OVS and wants to use it as a provider for generic bonds and
bridge. It actually means that he needs to set default provider in
network_scheme for l23network puppet module to 'ovs' instead of 'lnx'.
Imagine, he has put this magical OVS into a package and created a plugin.
The problem here will be that he needs to override what network serializer
is sending to the nodes.

But the problem here is that he cannot do it without editing Nailgun code
or override this serializer in any way.

* Case B. Make Swift Partitions Known to Fuel Library

Imagine, you altered the way you partition your disk in Nailgun. You
created a special role for swift disks which should occupy the whole disk.
In this case you should be able to get this info from api and feed it to
swift deployment task. But it is not so easy - this stuff is still
hardcoded in deployment serializers like {mp} field of nodes array of
hashes.

* Proposed solution

In order to tackle this I propose to extract these so called serializers
(see links [1] and [2]) and put them closer to library. You can see that
half of the code is actually duplicated for deployment and provsioning
serializers and there is actually no inheritance of common code betwen
them. If you want to introduce new attribute and put it into astute.yaml,
you will need to rewrite Nailgun code. This is not very
deployment/sysop/sysadmin engineer-friendly. Essentially, the proposal is
to introduce a library of such `serializers` (I would like to call them
translators actually) which could leverage inheritance, polymorphism and
incapsulation pretty much in OOP mode but with ability for deployment
engineers to apply versioning to serializers and allow each particular task
to work with different sources of data with different versions of API.

What this actually means: each task has a step called 'translation' which
fetches attributes from any arbitrary set of sources and converts them into
the format that is consumable by the deployment stage of this task. From
our current architectural point of view it will look like generation of a
set of yaml files that will be merged by hiera so that each puppet task can
leverage the power of hiera.

This actually means that in scope of our modularization initiative each
module should have an API which will be accessed by those tasks in runtime
right before the tasks are executed. This also means that if a user changes
some of the values in the databases of those modules, rerun of such task
will lead to a different result of 'translation' and trigger some actions
like 'keystone_config ~> Service[keystone]' in puppet.

There is a tough discussion (etherpad here:[4]) on:

1) how to handle versioning/revert capabilities
2) where to store output produced by those 'translators'
3) which type of the storage to use

Please, feel free to provide your feedback on this approach and tell me
where this approach is going to be wrong.

Re: [openstack-dev] [puppet][Fuel] OpenstackLib Client Provider Better Exception Handling

2015-10-15 Thread Vladimir Kuklin
Gilles,

5xx errors like 503 and 502/504 could always be intermittent operational
issues. E.g. when you access your keystone backends through some proxy and
there is a connectivity issue between the proxy and backends which
disappears in 10 seconds, you do not need to rerun the puppet completely -
just retry the request.

Regarding "REST interfaces for all Openstack API" - this is very close to
another topic that I raised ([0]) - using native Ruby application and
handle the exceptions. Otherwise whenever we have an OpenStack client
(generic or neutron/glance/etc. one) sending us a message like '[111]
Connection refused' this message is very much determined by the framework
that OpenStack is using within this release for clients. It could be
`requests` or any other type of framework which sends different text
message depending on its version. So it is very bothersome to write a bunch
of 'if' clauses or gigantic regexps instead of handling simple Ruby
exception. So I agree with you here - we need to work with the API
directly. And, by the way, if you also support switching to native Ruby
OpenStack API client, please feel free to support movement towards it in
the thread [0]

Matt and Gilles,

Regarding puppet-healthcheck - I do not think that puppet-healtcheck
handles exactly what I am mentioning here - it is not running exactly at
the same time as we run the request.

E.g. 10 seconds ago everything was OK, then we had a temporary connectivity
issue, then everything is ok again in 10 seconds. Could you please describe
how puppet-healthcheck can help us solve this problem?

Or another example - there was an issue with keystone accessing token
database when you have several keystone instances running, or there was
some desync between these instances, e.g. you fetched the token at keystone
#1 and then you verify it again keystone #2. Keystone #2 had some issues
verifying it not due to the fact that token was bad, but due to the fact
that that keystone #2 had some issues. We would get 401 error and instead
of trying to rerun the puppet we would need just to handle this issue
locally by retrying the request.

Actually, as you know, with Fuel we are shipping our code to people who
have their own infrastructure. We do not have any control over that
infrastructure and any information about it. So we should expect the worst
- that sometimes such issues will happen and we need to take care of them
in the best possible way, e.g. someone tripped the wire and then put it
back into the switch. And it seems that we can do it right in puppet code
instead of making user wait for puppet rerun.

Again, what you described is for the case when the system was in some
undesirable  state like reading from incorrect database and then got into
persistent working state. And you solve it by making load balancer aware of
which backend to send request to. But I am talking about sporadic failures
which from the statistical point of view look negligible and should not be
handled by load balancer. Imagine the situation when load balancer is ok
with that backend and this backend faces intermittent operational issue
like getting garbled response or having some bug in the code. This is a
sporadic failure which will not be caught by load balancer because if you
make it so sensitive to such issues it will behave poorly. So, I think, the
best option here is to handle such issues on application level.

[openstack-dev] [Fuel] Fuel Library Component Lead Nomination

2015-10-14 Thread Vladimir Kuklin
Fuel Librarians

I would like to nominate myself as a Candidate for Fuel Library Component
Lead position

Let me mention the list of main points I would like to work on. This list
is going to essentially resemble my PTL candidacy item list but it will
also differ from it significantly.

* General Standards of Decision Making

This assumes that each design decision on architecture must be applied
according to the sufficient data and expert analysis performed by subject
matter experts and cold and heartless machines that should run tests and
collect metrics of existing and proposed solutions to figure out the best
solution. Each decision on the new library or tool to choose must be
accompanied by clear report showing that this change actually makes
difference. I will start working on the unified toolchain and methodology
on how to make decisions immediately.

* HA Polishing

This one has always been one of the strongest parts of Fuel and we are
using our own unique and innovative ways of deploying HA architecture.
Nevertheless, we still have many things to work on to make it perfect:

1) Fencing and power management facilities
2) Node health monitoring
3) RabbitMQ clusterer plugin

* Reference Architecture Changes

It seems pretty obvious that our reference architecture requires some
simplification and polishing. We have several key-value storages, we are
using several HTTP servers/proxies and so on.
This makes us support lots of stuff instead of concentrating on a 'golden'
set of tools and utilities and making them work perfectly.
I want to spend significant time on figuring out possible solutions for
redefining of our architecture based on aforementioned principles.

* Quality and Deployment Velocity

Although we are among the only projects who run very extensive set of tests
including for each commit into Fuel Library - we can still work on many
things for perfect QA and CI.
These are:

1) deployment integration tests for all the components, e.g. run deployment
for each deployment-related component like nailgun, nailgun-agent,
fuel-agent, fuel-astute and others
2) significantly increase test coverage: e.g. cover each deployment task
with noop test, increase unit test coverage for all the Fuel-only modules
3) work on the ways of automated generation of test plans for each
particular feature and bugfix including regression, functional, scale,
stress and other types of tests
4) work on the way of introducing more granular tests for fuel deployment
components - we have an awesome framework to get faster feedback, written
by fuel QA team, but we have not yet integrated it into our CI

* Flexibility and Scalability

We have a lot of work to do on orchestration and capabilities of our
deployment engine.

We need to introduce hierarchy for deployment attributes like for the whole
cluster, for racks, for nodes and tasks themselves.

We also need to work on our provisioning scalability parts such as moving
towards iPXE + peer2peer base image distribution.

* Documentation

It seems we have lots of good tools like our devops toolkit, noop tests and
other things. But this info is not available to external contributors and
plugin developers. Even Fuel engineers do not know everything about how
these tools work.  I am going to setup several webinars and write a dozen
of articles on how to develop and test Fuel Library.

* Community

And the last but not least - community collaboration. We are doing great
job while gluing existing deployment libraries and testing their
integration. Community folks like puppet-openstack are also doing great
job. And, instead of duplicating it, I would like to merge with upstream
code as much as possible thus freeing our resources onto the things we do
the best along with sharing the stuff we do the best with community by
testing results of their work against our reference architecture and
installations.

Additionally, it is worth to mention that I envision significant value in
making Fuel able to install current OpenStack trunk code thus allowing us
to set up Fuel CI for each piece of OpenStack and allowing OpenStack
developers to test their code against multi-host HA-enabled reference
architecture in an easy and automated way.

Thank you all for your time and consideration!

[openstack-dev] [puppet][Fuel] Using Native Ruby Client for Openstack Providers

2015-10-13 Thread Vladimir Kuklin
Puppetmaster and Fuelers,

Last week I mentioned that I would like to bring the theme of using native
ruby OpenStack client and use it within the providers.

Emilien told me that I had already been late and the decision was made that
puppet-openstack decided to not work with Aviator based on [0]. I went
through this thread and did not find any unresolvable issues with using
Aviator in comparison with potential benefits it could have brought up.

What I saw actually was like that:

* Pros

1) It is a native ruby client
2) We can import it in puppet and use all the power of Ruby
3) We will not need to have a lot of forks/execs for puppet
4) You are relying on negotiated and structured output provided by API
(JSON) instead of introducing workarounds for client output like [1]

* Cons

1) Aviator is not actively supported
2) Aviator does not track all the upstream OpenStack features while native
OpenStack client does support them
3) Ruby community is not really interested in OpenStack (this one is
arguable, I think)

* Proposed solution

While I completely understand all the cons against using Aviator right now,
I see that Pros above are essential enough to change our mind and invest
our own resources into creating really good OpenStack binding in Ruby.
Some are saying that there is not so big involvement of Ruby into
OpenStack. But we are actually working with Puppet/Ruby and are invloved
into community. So why should not we own this by ourselves and lead by
example here?

I understand that many of you do already have a lot of things on their
plate and cannot or would not want to support things like additional
library when native OpenStack client is working reasonably well for you.
But if I propose the following scheme to get support of native Ruby client
for OpenStack:

1) we (community) have these resources (speaking of the company I am
working for, we at Mirantis have a set of guys who could be very interested
in working on Ruby client for OpenStack)
2) we gradually improve Aviator code base up to the level that it
eliminates issues that are mentioned in  'Cons' section
3) we introduce additional set of providers and allow users and operators
to pick whichever they want
4) we leave OpenStackClient default one

Would you support it and allow such code to be merged into upstream
puppet-openstack modules?

Thanks for your input. So, I mentioned the following - Fuel guys can
contribute into Ruby client for OpenStack as we are also interested in
making it faster. That's why I asked for support in case we invest
substantial effort (as we do not want to waste our time on things that will
not land into upstream) and asked if the approach that I proposed is OK
with you.

Re: [openstack-dev] [puppet][Fuel] Using Native Ruby Client for Openstack Providers

2015-10-13 Thread Vladimir Kuklin
Rich

Thanks for your feedback - let me comment on a couple of things.

First of all, I do not think we have complete support for any action in
OpenStack client right now - we still need to rely on neutronclient,
glanceclient, etc.

Secondly, regarding Ruby power - this is about any good programming
language, not about Ruby - I can simply mention better exception handling
as you would not need to parse the output and generate your own exceptions
- this makes it easier to support the whole set of providers. As I
mentioned earlier, we do not have perfect exception handling for
intermittent operational issues.

Finally, I understand that you do not see metrics. Although, it seems to me
absolutely obvious that fork/exec is going to be the problem here, that's
OK, I will work on that and come up with quantitative analysis.

What I think is that we need to somehow group the bugs so that after they
are initially triaged particular component developers can understand which
bugs to get from the pool of unassigned bugs. Could you please show how you

[openstack-dev] [puppet][Fuel] OpenstackLib Client Provider Better Exception Handling

2015-10-08 Thread Vladimir Kuklin
Hi, folks

* Intro

Per our discussion at Meeting #54 [0] I would like to propose the uniform
approach of exception handling for all puppet-openstack providers accessing
any types of OpenStack APIs.

* Problem Description

While working on Fuel during deployment of multi-node HA-aware environments
we faced many intermittent operational issues, e.g.:

401/403 authentication failures when we were doing scaling of OpenStack
controllers due to difference in hashing view between keystone instances
503/502/504 errors due to temporary connectivity issues
non-idempotent operations like deletion or creation - e.g. if you are
deleting an endpoint and someone is deleting on the other node and you get
404 - you should continue with success instead of failing. 409 Conflict
error should also signal us to re-fetch resource parameters and then decide
what to do with them.

Obviously, it is not optimal to rerun puppet to correct such errors when we
can just handle an exception properly.

* Current State of Art

There is some exception handling, but it does not cover all the
aforementioned use cases.

* Proposed solution

Introduce a library of exception handling methods which should be the same
for all puppet openstack providers as these exceptions seem to be generic.
Then, for each of the providers we can introduce provider-specific
libraries that will inherit from this one.

Our mos-puppet team could add this into their backlog and could work on
that in upstream or downstream and propose it upstream.

What do you think on that, puppet folks?

2015-10-06 Thread Vladimir Kuklin
Which is actually contradictory and ambiguous and shows that PTL has less
power than CLs while CLs at the same time have less power than PTL. I think
this is the time when universe should collapse as we found that time-space
is contradicting laws of propositional calculus.

Re: [openstack-dev] [fuel] What to do when a controller runs out of space

Eugene

With all due respect to you and other OpenStack developers, I as a system
administrator do not believe when someone says that something is working
that way. Actually, what I would prefer to do is to stress-test these
services on their 'statelessness'. Currently we have l3-agent not so
stateless and lacking centralized synchronization in proper way which you
have no actually defied. So I agree - let's move this into different thread
and not hijack this one.

[openstack-dev] [Fuel][PTL] PTL Candidates Q Session

2015-09-29 Thread Vladimir Kuklin
Folks

I think it is awesome we have three candidates for PTL position in Fuel. I
read all candidates' emails (including mine own several times :-) ) and I
got a slight thought of not being able to really differentiate the
candidates platforms as they are almost identical from the high-level point
of view. But we all know that the devil is in details. And this details
will actually affect project future.

Thus I thought about Q session at #fuel-dev channel in IRC. I think that
this will be mutually benefitial for everyone to get our platforms a little
bit more clear.

Let's do it before or right at the start of actual voting so that our
contributors can make better decisions based on this session.

I suggest the following format:

1) 3 questions from electorate members - let's put them onto an etherpad
2) 2 questions from a candidate to his opponents (1 question per opponent)
3) external moderator - I suppose, @xarses as our weekly meeting moderator
could help us
4) time and date - Wednesday or Thursday comfortable for both timezones,
e.g. after 4PM UTC or right after fuel weekly meeting.

What do you think, folks?

[openstack-dev] [Fuel] Fuel PTL Candidacy

2015-09-28 Thread Vladimir Kuklin
 The Monster of Synergy)

And the last but not least - community collaboration. We are doing great
job while gluing existing deployment libraries and testing their
integration. Community folks like puppet-openstack are also doing great
job. And, instead of duplicating it, I would like to merge with upstream
code as much as possible thus freeing our resources onto the things we do
the best along with sharing the stuff we do the best with community by
testing results of their work against our reference architecture and
installations.

Additionally, it is worth to mention that I envision significant value in
making Fuel able to install current OpenStack trunk code thus allowing us
to set up Fuel CI for each piece of OpenStack and allowing OpenStack
developers to test their code against multi-host HA-enabled reference
architecture in an easy and automated way.

* Conclusion

I am sure that going this way will make our project better and ramp up our
project quality and growth significantly, allow us to finally join Big Tent
and become the default most effective and easy-to-use installer and manager
of OpenStack clouds.

I will be happy to lead Fuel project during this cadence with this pretty
consistent and wide platform. It seems a little bit ambitious and not so
simple to implement it - but I expect help from Component Leads for
Fuel-Library and Fuel-Python as well as yours.

Remember, as Red Queen said: "you must run at least twice as fast as that!"

Thank you all for your time and consideration!

Re: [openstack-dev] [fuel] PTL & Component Leads elections

2015-09-24 Thread Vladimir Kuklin
Dmitry

Thank you for the clarification, but my questions still remain unanswered,
unfortunately. It seems I did not phrase them correctly.

1) For each of the positions, which set of git repositories should I run
this command against? E.g. which stackforge/fuel-* projects contributors
are electing PTL or CL?
2) Who is voting for component leads? Mike's email says these are core
reviewers. Our previous IRC meeting mentioned all the contributors to
particular components. Documentation link you sent is mentioning all
contributors to Fuel projects. Whom should I trust? What is the final
version? Is it fine that documentation contributor is eligible to nominate
himself and vote for Library Component Lead?

Until there is a clear and sealed answer to these questions we do not have
a list of people who can vote and who can nominate. Let's get it clear at
least before PTL elections start.

Re: [openstack-dev] [fuel] PTL & Component Leads elections

2015-09-23 Thread Vladimir Kuklin
Dmitry, Mike

Thank you for the list of usable links.

But still - we do not have clearly defined procedure on determening who is
eligible to nominate and vote for PTL and Component Leads. Remember, that
Fuel still has different release cycle and Kilo+Liberty contributors list
is not exactly the same for "365days" contributors list.

Can we finally come up with the list of people eligible to nominate and
vote?

Re: [openstack-dev] [fuel] PTL & Component Leads elections

2015-09-18 Thread Vladimir Kuklin
Sergey, Fuelers

This is awesome news!

By the way, I have a question on who is eligible to vote and to nominate
him/her-self for both PTL and Component Leads. Could you elaborate on that?

And there is no such entity as Component Lead in OpenStack - so we are
actually creating one. What are the new rights and responsibilities of CL?

Re: [openstack-dev] Apache2 vs uWSGI vs ...

2015-09-18 Thread Vladimir Kuklin
Folks

I think we do not need to switch to nginx-only or consider any kind of war
between nginx and apache adherents. Everyone should be able to use
web-server he or she needs without being pinned to the unwanted one. It is
like Postgres vs MySQL war. Why not support both?

May be someone does not need something that apache supports and nginx not
and needs nginx features which apache does not support. Let's let our users
decide what they want.

And the first step should be simple here - support for uwsgi. It will allow
for usage of any web-server that can work with uwsgi. It will allow also us
to check for the support of all apache-like bindings like SPNEGO or
whatever and provide our users with enough info on making decisions. I did
not personally test nginx modules for SAML and SPNEGO, but I am pretty
confident about TLS/SSL parts of nginx.

Moreover, nginx will allow you to do things you cannot do with apache, e.g.
do smart load balancing, which may be crucial for high-loaded installations.

[openstack-dev] Apache2 vs uWSGI vs ...

2015-09-18 Thread Vladimir Kuklin
Folks

I just suggested to untie keystone from wsgi and implement uwsgi support.
And then let the user decide what he or she wants.

There is a plenty of auth modules for nginx also.

Nginx us much better as a proxy server and you know it.

Regarding mod wsgi and apache we already saw that it cannot handle simple
restart. I think this is not in any way acceptable from operations point if
view.

Re: [openstack-dev] [Fuel] Remove MOS DEB repo from master node

2015-09-10 Thread Vladimir Kuklin
Igor

Having poor access to the internet is a regular use case which we must
support. This is not a crazy requirement. Not having full ISO makes cloud
setup harder to complete. Even more, not having hard requirement to create
a mirror will detract newcomers. I can say that if I were a user and saw a
requirement to create mirror I would not try the product with comparison to
the case when I can get a full ISO with all the stuff I need.

This is not the case to tell users if they are stupid are not. We are
working for our users, not vice versa.
