Re: juju as a web service

[Sebastian]

Hey folks!

I think that Juju can bring a hole new era for devs and ops, but devs need
something more than charms, they need a bridge between Juju and their
automation (Continues Integration / Delivery) tools in order to deploy
their applications, like a PaaS does.

We are working to deliver Juju and StriderCD to empower people to innovate.

Cheers,
Sebas.

These notes were written while the list command was approved but not yet
landed.  I'm not entirely sure if the 'juju user list' command made it
into the -alpha2 release or not.  If not, never fear, it will be in
-alpha3 (and the 1.21 full release).

Juju devel 1.21-alpha2 is available

[Curtis Hovey-Canonical]

A new development release of Juju, juju-core 1.21-alpha2, is now
available. This release replaces 1.21-alpha1.


Getting Juju

juju-core 1.21-alpha2 is available for utopic and backported to earlier
series in the following PPA:

https://launchpad.net/~juju/+archive/devel

Upgrading from stable releases to devel releases is not
supported. You can upgrade test environments to development releases
to test new features and fixes, but it is not advised to upgrade
production environments to 1.21-alpha2.

The devel packages in this archive use the devel simple-streams.
You must configure the 'agent-metadata-url' option in your
environments.yaml to use the matching juju tools.

agent-metadata-url: https://streams.canonical.com/juju/devel/tools

'tools-metadata-url' was renamed to 'agent-metadata-url'.


Notable Changes

* Provider storage is no longer mandatory (for new providers)
* AWS now defaults to using images with SSD storage
* The juju ensure-availability command now supports placement directive
* Automatic placement using MAAS zones
* Various apt improvements
* Improved use of availability zones on Openstack
* The api-info command shows the settings used to connect to juju
* state-server Multiple users are now supported.


Provider storage is no longer mandatory (for new providers)

Storage associated with a particular cloud (S3 for AWS, Swift for
Openstack etc) was a mandatory requirement when developing a provider to
allow Juju to deploy workloads to any particular cloud platform. This
requirement is no longer necessary. Although existing providers still
use cloud storage (to some extent), new providers can be written without
needing to provide a storage implementation.

Upgrading existing environments will take longer than normal because
the state-server will migrate data from the old storage location. During
this time status will report that the upgrade will be retried over many
minutes:

Upgrade to 1.21-alpha2 failed (will retry): migrate tools into
environment storage: cannot find tools in provider storage: no tools
available


AWS now defaults to using images with SSD storage

When deploying workloads onto AWS, images with SSD volumes are now
preferred. If no such image are available, an image using EBS storage
will be used as a fallback.


The juju ensure-availability command now supports placement directive

Just as 'juju bootstrap' supports the ability to specify a particular
node using '--to' placement directives, so too can
'juju ensure-availability' specify a comma separate list of machine to
use for any newly required state servers.
For example:

juju ensure-availability -n 3 --to name1,name2


Automatic placement using MAAS zones

The MAAS provider is now on par with AWS and Openstack providers in
supporting automatic placement using zones.


Various apt improvements

You can now configure 'apt-mirror' in environments.yaml to specify the
mirror used by all the machines provisioned in the environment.

apt-mirror: http://my.archive.ubuntu.com

On precise, the cloud tools archive is now pinned before calling apt
upgrade to ensure its packages are a lower priority than the default
precise archives. Charms developed on precise will see the same packages
when deployed into a juju provisioned machine. If your precise charm
requires packages from the cloud tool's archive, you can use the
'target-release' option to specify the archive to select.

apt-get --target-release precise-updates/cloud-tools my-package

The local-provider skips apt updates and upgrades by default for faster
provisioning. 1.21-alpha1 introduced the ability to disable apt upgrades
and updates for faster provisioning. The default for local provider
were both false. This release introduces a default of true for apt
update operations for local provider. If you wish to enable updates and
upgrades in your local development, update your environments.yaml.

enable-os-upgrade: true
enable-os-refresh-update: true


Improved use of availability zones on Openstack

The Openstack provider now attempts to start instances in all available
zones until it finds one that succeeds, rather than trying just the
first zone and failing. This aligns Openstack behavior with what was
already done for AWS.


The api-info command shows the settings used to connect to juju
state-server.

The 'juju api-info' command shows the settings used to connect to the
juju state-server's API. You can see the settings for all the fields
(except for password) like so:

juju api-info

If you want to see the password being used, you need to either use the
'--password' option

juju api-info --password

Or specify the password field as the only field to show

juju api-info password

You can learn the value of any field by including it in the command
line. For example, to learn the name of user created during bootstrap,
type

juju api-info user


Multiple-user Support

Juju now supports multiple people connecti

I've been watching this one develop, and it was indeed a long road to
promulgation.

Congrats on the win Xiaoming Wang!

[Review Queue] hpcc

[Matt Bruzek]

I spent some time reviewing the High Performance Computing Cluster (HPCC)
charm today.  For those that do not know HPCC 
is a player in Big Data as an alternative platform to Hadoop.

The review passed and hpcc is the newest charm in the charm store!

https://bugs.launchpad.net/charms/+bug/1272083

This charm requires a minimum of 4GB nodes to deploy all the thor and roxie
processes so you will have to use the constraints flag to deploy it from
juju on a cloud properly.  All this is documented in the well written
README.md file inside the charm.

Thanks to the developer Xiaoming Wang for all the work and the patience
with the review process!

Go big data!

It's so good to be among you guys. I have resolved most of my queries 
here so I would like to thank you all.

Have pushed my charms, just waiting for the reviewers and charmers.

Thanks again,
