It's totally cool to test for cookbook style and for JSON and Ruby correctness, but we need to test whether a set of roles/cookbooks in the repo can be successfully deployed into a bare-metal cluster since that is the whole point ;) Alternately, deploying into a virtualized cluster would also be fine... I look forward to working with you guys to set this up. -jay ___ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp

I imagine running foodcritic on a chef repo owned by openstack would not be hard to do if that's something we want to have/own/do.

Sweet. Let me know if there are any things that people are wanting related to any of these projects from the OpenStack CI infrastructure. Foodcritic/jsonlint seem pretty easy - deployments on to bare nodes using the chef stuff similar to our devstack-based installs might take a little more work and would need to be planned for. :) > Thanks, > Matt Ray > Senior Technical Evangelist | Opscode Inc. > m...@opscode.com | (512) 731-2218 > Twitter, IRC, GitHub: mattray > > > On Wed, Jul 11, 2012 at 9:39 AM, Sullivan, Jon Paul > wrote: >>> -Original Message- >>> From: openstack-bounces+jonpaul.sullivan=hp@lists.launchpad.net >>> [mailto:openstack-bounces+jonpaul.sullivan=hp@lists.launchpad.net] >>> On Behalf Of Monty Taylor >>> Sent: 11 July 2012 14:37 >>> To: Matt Ray >>> Cc: Nati Ueno; openstack@lists.launchpad.net >>> Subject: Re: [Openstack] [CHEF] Clarification on osops/chef- >>> repo/roles/nova-compute.rb >>> >>> >>> >>> On 07/10/2012 04:23 PM, Matt Ray wrote: >>>> Bluntness appreciated, this process is already in motion. >>>> http://opscode.com/openstack was launched 2 weeks ago and I promptly >>>> left for conferences and vacation.

Re: [Openstack] [CHEF] Clarification on osops/chef-repo/roles/nova-compute.rb
I know Rackspace gates their commits with foodcritic (https://rubygems.org/gems/foodcritic), which is becoming the standard we're recommending to people for cookbooks style. For doing Travis CI testing automatically, I plan on adding testing outlined in this post: http://nathenharvey.com/blog/2012/05/29/mvt-foodcritic-and-travis-ci/ Opscode also has a "test-kitchen" project in progress that will be running CI with Jenkins on a number of platforms automatically for community cookbooks, we'll be pushing the OpenStack cookbooks on that as well as soon as it's made public and open sourced.

So, Nati and I are looking to use either the osops chef-repo or
something similar as the basis of the new TryStack zone chef deployment.
I've been going through the recipes and roles and I have a question on
the nova-compute *role*:
https://github.com/osops/chef-repo/blob/master/roles/nova-compute.rb
I'm wondering why the nova-api recipe is in the runlist for
nova-compute?
Because metadata needs to run on the compute hosts in the default
layout. This should
be switched to use nova-api-metadata instead of nova-api, but the
split out hasn't been done yet.
OK, I will work on splitting this out a bit more effectively.
One additional question, though. In opening up the
/cookbooks/nova/recipes/nova/compute.rb file, you will notice this at
the top:
include_recipe "nova::api"
Therefore, unless I am mistaken, the nova-compute *role*'s runlist
actually doesn't need to contain both nova-api AND nova-compute since
apparently the nova-compute *recipe* already includes all of the
nova-api recipe.
Would you agree with that?
In addition, I was wondering if y'all had considered making more use of
roles instead of recipes to allow most of the attribute assignment and
variation to be in the combination of roles assigned to a host, instead
of recipes combined in a role?
For example, right now, there is a "nova-controller" role that looks
like this:
name "nova-controller"
description "Nova controller node (vncproxy + rabbit)"
run_list(
"role[base]",
"recipe[nova::controller]"
)
Because most of the special sauce is in the nova::controller recipe, I
have to go into that recipe to see what the role is composed of:
include_recipe "mysql::server"
include_recipe "openssh::default"
include_recipe "rabbitmq::default"
include_recipe "keystone::server"
include_recipe "glance::registry"
include_recipe "glance::api"
include_recipe "nova::nova-setup"
include_recipe "nova::scheduler"
include_recipe "nova::api"
if platform?(%w{fedora})
# Fedora skipping vncproxy for right now
else
include_recipe "nova::vncproxy"
end
But what this recipe really is is an opinionated description of a
"controller role". If the role was, instead, structured like so:
name "nova-controller"
description "Nova Controller - All major API services and control
servers like MySQL and Rabbit"
run_list(
"role[base]",
"recipe[mysql::server]",
"recipe[openssh::default]",
"recipe[rabbitmq::default]",
"recipe[keystone::server]",
"recipe[glance::api]",
"recipe[glance::registry]",
"recipe[nova::scheduler]",
"recipe[nova::api]",
)
Then the deployer can more easily switch up the way they deploy
OpenStack servers by merely changing the role -- say, removing the
Rabbit service and putting it somewhere else -- WITHOUT having to modify
a recipe in a Git submodule in the upstream cookbooks.
Furthermore, if we broke out more roles -- such as "control-services"
which might be MySQL and Rabbit only -- than we could make the "super
roles" ,like the nova-controller role above, more of a "put this and
that role together, like so:
name "nova-controller"
description "Nova Controller - All major API services and control
servers like MySQL and Rabbit"
run_list(
"role[base]",
"role[control_services]",
"recipe[keystone::server]",
"recipe[glance::api]",
"recipe[glance::registry]",
"recipe[nova::scheduler]",
"recipe[nova::api]",
)
This all makes sense to me. Ron?
Ron, any disagreement here?
Finally, I've noticed that there are aren't any HA options in the osops
recipes -- specifically around MySQL. Are there plans to do so? We use
heartbeat/Pacemaker/DRBD in the original TryStack cookbooks [1] and
environments to get simple HA solutions up and would love to see those
in the upstream.
Either of you, any thoughts on this front?
Thanks!

Re: [Openstack] [CHEF] Clarification on osops/chef-repo/roles/nova-compute.rb
Apologies in advance for my blunt and somewhat dour response, Matt. I'm not singling you out at all, and I know you've tried your best to get the various Chef stakeholders to work together. Also apologies for top-posting, but there's not a whole lot of use inline posting this. tl;dr - We need to stop the needless fracturing of the operational knowledge of the Chef community and try working as a team towards some common goals instead of creating fork after fork of repos of Chef cookbooks. There is a ton of wasted effort in this area. Proposal: * Get our act together and treat Chef repos (and puppet/juju/whatever) as we do other OpenStack core and supporting projects -- use Gerrit, use a CI gating system, do real code reviews on it, and in general treat them as a supporting OpenStack project * Mark ALL Chef repos that are not currently maintained with an OBSELETE marker and/or DELETE the repo on Github * Consolidate all *cookbooks* into a repository in github.com/openstack/chef-repo * Use git submodules to manage cookbooks that are upstreamed in github.com/opscode/ that have little to no changes in them * Actually fix the documentation of the dang cookbooks -- right now, half of them include the documentation from the memcache cookbook, as they were lazily copy-pasted around, or the standard example doc that is created when using something like knife. * Put as much variation in deployment philosophy into *roles* and attribute overrides/defaults More/Rant/Details - Maybe it's just the open source developer in me, but I don't understand why there is such an aversion to coordination in the deployment/ops community around the scripts and deployment cookbooks/modules/charms/whatever. Is it that everyone has a different idea of what is best? Is it because deployers/ops folks think that coordinating with other contributors is too time-consuming? Is it because the chef repos are not controlled in the same way as, say, devstack or the core projects, with an automated patch queue manager and code review system that actually encourages debate over patches? A combination of all of the above? Over the last 2 years, I've worked at 3 companies in the OpenStack ecosystem. All three companies had their own repos of Chef cookbooks (still do to this day). 50-60% of the content of these cookbooks is identical. 10-20% of the content of these cookbooks is different -- but only slightly or cosmetically. And a good portion of the remaining 20-40% are differences that are incorrectly (IMHO) placed in the cookbooks and recipes instead of where they should be: in roles and environments, with cookbooks created that deal with variations in deployments with attributes and the occasional if/else block. In trying to determine the appropriate Chef repo to use for the TryStack project, we found the following repo: https://github.com/osops/chef-repo to have the most up-to-date. I've since been told this repo is no longer maintained. This is very frustrating, not because of this particular repo, but because this is just one in a long line of neglected and forgotten forks of chef cookbook repositories. The fact that the default Chef behaviour and Opscode documentation encourages the copy/pasting of cookbooks all over the place and GitHub itself encourages the random and promiscuous forking of repos doesn't help. Let's get real about the deployment/ops code and cookbooks/modules/charms. Let's treat them the same way we do code in the core projects and supporting projects.

Just a heads up, I'm working on building unified community-driven
cookbooks over in https://github.com/opscode/openstack-chef-repo (and
repos for the individual cookbooks). These are forked from Rackspace's
cookbooks and I'm working with them and others to make reusable,
well-documented and supported Chef cookbooks for OpenStack. I'll make
a larger announcement around them once I have a working quickstart
document for them.

Ron, any disagreement here?

Either of you, any thoughts on this front?
Thanks!

Because metadata needs to run on the compute hosts in the default layout. This
should
be switched to use nova-api-metadata instead of nova-api, but the split out
hasn't been done yet.

This all makes sense to me. Ron?

[Openstack] [CHEF] Clarification on osops/chef-repo/roles/nova-compute.rb
Hi Ron, cc'ing the openstack ML for extra eyes and opinions...
So, Nati and I are looking to use either the osops chef-repo or
something similar as the basis of the new TryStack zone chef deployment.
I've been going through the recipes and roles and I have a question on
the nova-compute *role*:
https://github.com/osops/chef-repo/blob/master/roles/nova-compute.rb
I'm wondering why the nova-api recipe is in the runlist for nova-compute?
In addition, I was wondering if y'all had considered making more use of
roles instead of recipes to allow most of the attribute assignment and
variation to be in the combination of roles assigned to a host, instead
of recipes combined in a role?
For example, right now, there is a "nova-controller" role that looks
like this:
name "nova-controller"
description "Nova controller node (vncproxy + rabbit)"
run_list(
"role[base]",
"recipe[nova::controller]"
)
Because most of the special sauce is in the nova::controller recipe, I
have to go into that recipe to see what the role is composed of:
include_recipe "mysql::server"
include_recipe "openssh::default"
include_recipe "rabbitmq::default"
include_recipe "keystone::server"
include_recipe "glance::registry"
include_recipe "glance::api"
include_recipe "nova::nova-setup"
include_recipe "nova::scheduler"
include_recipe "nova::api"
if platform?(%w{fedora})
# Fedora skipping vncproxy for right now
else
include_recipe "nova::vncproxy"
end
But what this recipe really is is an opinionated description of a
"controller role". If the role was, instead, structured like so:
name "nova-controller"
description "Nova Controller - All major API services and control
servers like MySQL and Rabbit"
run_list(
"role[base]",
"recipe[mysql::server]",
"recipe[openssh::default]",
"recipe[rabbitmq::default]",
"recipe[keystone::server]",
"recipe[glance::api]",
"recipe[glance::registry]",
"recipe[nova::scheduler]",
"recipe[nova::api]",
)
Then the deployer can more easily switch up the way they deploy
OpenStack servers by merely changing the role -- say, removing the
Rabbit service and putting it somewhere else -- WITHOUT having to modify
a recipe in a Git submodule in the upstream cookbooks.
Furthermore, if we broke out more roles -- such as "control-services"
which might be MySQL and Rabbit only -- than we could make the "super
roles" ,like the nova-controller role above, more of a "put this and
that role together, like so:
name "nova-controller"
description "Nova Controller - All major API services and control
servers like MySQL and Rabbit"
run_list(
"role[base]",
"role[control_services]",
"recipe[keystone::server]",
"recipe[glance::api]",
"recipe[glance::registry]",
"recipe[nova::scheduler]",
"recipe[nova::api]",
)
Finally, I've noticed that there are aren't any HA options in the osops
recipes -- specifically around MySQL. Are there plans to do so? We use
heartbeat/Pacemaker/DRBD in the original TryStack cookbooks [1] and
environments to get simple HA solutions up and would love to see those
in the upstream.
Thanks and all the best guys,
-jay
