| bloodearnest | heya folks - am using lxc environment, trying to add a private ppa in my install hook, but apt-cacher-ng is getting in the way. Is there anyway to run a local lxc env without it? | 11:20 |

| stokachu | jcastro: http://www.astokes.org/post/2013-07-14-juju-gunicorn-apache-django | 11:28 |
| stokachu | not sure if you saw that yet, was hoping to get some contributors added to the github project | 11:28 |
| stokachu | https://github.com/battlemidget/juju-apache-gunicorn-django | 11:29 |
| stokachu | going to add rabbitmq support soon as well and maybe haproxy | 11:30 |
| pavelpachkovskij | is there a way I can change config attribute from a hook? | 12:44 |
| pavelpachkovskij | something like "config-set attr=value" | 12:44 |
| marcoceppi | pavelpachkovskij: No, you can only manipulate config from the juju cli | 13:07 |
| marcoceppi | It's not designed to be manipulated from within hooks | 13:08 |
| pavelpachkovskij | marcoceppy, and if I try to run juju set ... from hook? | 13:08 |
| pavelpachkovskij | marcoceppi, sorry for typo | 13:09 |
| marcoceppi | You can try, but you'd have to also include a copy of your ssh private key and ~/.juju/environments.yaml file in order to even start using the juju cli from the charm. | 13:09 |
| pavelpachkovskij | I see | 13:09 |
| marcoceppi | pavelpachkovskij: let me just say, while you can do this, it likely won't be accepted in to the charm store. This is definitely not a good practice | 13:10 |
| pavelpachkovskij | I understand it | 13:10 |
| marcoceppi | The impression config has for users is *they* set it, having the charm do it will break that story and preception | 13:10 |
| pavelpachkovskij | marcoceppi, my problem is that I want to do something like this: | 13:10 |
| pavelpachkovskij | juju set sample-rails command='rake db:migrate' | 13:10 |
| pavelpachkovskij | but I can't track for changes if I can't modify this variable from the instance | 13:11 |
| pavelpachkovskij | though this is a huge workaround there is no other way to run command within application | 13:11 |
| marcoceppi | pavelpachkovskij: So what you're trying to do is send ad-hoc commands to the charm? | 13:11 |
| pavelpachkovskij | yes | 13:12 |
| pavelpachkovskij | It would be nice to have support of ad-hoc commands built into juju itself | 13:13 |
| pavelpachkovskij | marcoceppi, do you have smth like this in the roadmap? | 13:13 |
| marcoceppi | pavelpachkovskij: There's a few problems with this particular example. When you run juju set it will run config-changed on all units. Imagine having a deployment at scale (2+ units) they'd all start executing a rake db:migrate, which I can see as being particularly harmful | 13:13 |
| pavelpachkovskij | I already thought about this | 13:13 |
| pavelpachkovskij | marcoceppi, and work out a solution with different roles | 13:14 |
| pavelpachkovskij | marcoceppi, exactly the same way how it is in capistrano | 13:14 |
| marcoceppi | pavelpachkovskij: There's a mechanism for this kind of one-off command: `juju ssh <charm>/<unit-num> rake db:migrate` | 13:14 |
| pavelpachkovskij | marcoceppi, this will not work for my purposes | 13:14 |
| pavelpachkovskij | marcoceppi, issue with 2+ units solves with rack-master and rack-slave nodes in a cluster | 13:15 |
| pavelpachkovskij | marcoceppi, your solution requires user to now at least root folder | 13:15 |
| pavelpachkovskij | marcoceppi, maybe it's not the best example, but also I need to update application source code | 13:16 |
| marcoceppi | pavelpachkovskij: The other thing you can possibly do is trap the previous value of the config, something like `config-get command > .previous-cmd`, check if it's actually changed. The downside to this is, if they set command to be the same exact string again it won't get caught | 13:16 |
| pavelpachkovskij | marcoceppi, yes, this is the problem I'm trying to solve | 13:16 |
| pavelpachkovskij | marcoceppi, tracking the change from 'rake db:migrate' to 'rake db:migrate' | 13:17 |
| === cmagina-away is now known as cmagina | ||
| pavelpachkovskij | marcoceppi, it just doesn't trigger the hook | 13:17 |
| marcoceppi | pavelpachkovskij: there's no way currently, unfortunately. Could you describe the entire workflow? Is the command just a one-off or is it part of a bigger process? | 13:17 |
| pavelpachkovskij | marcoceppi, did you use heroku? | 13:18 |
| marcoceppi | pavelpachkovskij: I know of it, for the most part | 13:18 |
| pavelpachkovskij | marcoceppi, I want rack-charm with heroku like behavior | 13:18 |
| pavelpachkovskij | with support of custom commands and source code update mechanism | 13:18 |
| pavelpachkovskij | marcoceppi, actually I have a great progress with it, but I don't know how to solve this very problem | 13:19 |
| pavelpachkovskij | give me a second, I'll push my code to github | 13:19 |
| marcoceppi | pavelpachkovskij: what you can do instead, is have two config values sections, one that tracks the souce (source-url, source-branch, source-tag, whatever), then one that tracks what commands to run when doing an update (update-cmds). That way the user has described what they want done during updates and you can now trap when there's an update | 13:20 |
| pavelpachkovskij | https://github.com/Altoros/rack/blob/master/hooks/chef/cookbooks/rack/recipes/config-changed.rb | 13:20 |
| marcoceppi | ah, yes juju ssh really wouldn't help much here | 13:20 |
| pavelpachkovskij | marcoceppi, another problem with this approach is that if user change another attribute, command attribute will stay the same and cause another run of command | 13:22 |
| pavelpachkovskij | marcoceppi, I didn't get your idea with update-cmds | 13:22 |
| pavelpachkovskij | marcoceppi, can you expand with it? | 13:22 |
| marcoceppi | pavelpachkovskij: let me write a quick bash example | 13:22 |
| pavelpachkovskij | marcoceppi, waiting, thanks | 13:23 |
| marcoceppi | pavelpachkovskij: I'm not sure how well a bash example will translate to chef, but this was my idea: http://paste.ubuntu.com/5877478/ | 13:46 |
| pavelpachkovskij | marcoceppi, yeah... but... there are two issues: 1. Forcing users to write huge configs. 2. It's really hard to fully automate deployment. | 13:48 |
| pavelpachkovskij | marcoceppi, it's really common case when you want to run custom rake task | 13:48 |
| marcoceppi | pavelpachkovskij: I don't see how it's anymore difficult than having to run juju set several times to complete tasks | 13:48 |
| pavelpachkovskij | marcoceppi, if user make a typo, he have to re-run all deployment | 13:49 |
| marcoceppi | pavelpachkovskij: Could you explain how a typo would force a re-run of deployment? | 13:50 |
| marcoceppi | I'm not grasping the use case very well | 13:51 |
| pavelpachkovskij | marcoceppi, forget, this issue is not very important | 13:51 |
| pavelpachkovskij | marcoceppi, I just don't like this idea | 13:51 |
| marcoceppi | pavelpachkovskij: We've not has a real strong use case for ad-hoc command running where `juju ssh` wasn't a valid solution. In this case, if you feel strongly about being able to do so, you might want to open a bug with juju-core to start a dialog on how this can be resolved within juju core. Either by allowing the resetting of config values in a hook context, or by adding some new mechanism in juju | 13:53 |
| pavelpachkovskij | marcoceppi, yep | 13:53 |
| marcoceppi | Also, juju ssh drops you in as the `ubuntu` user, not directly as root, if that was a previous concern of yours | 13:54 |
| pavelpachkovskij | marcoceppi, I know that it's ubuntu user, ssh makes it difficult to run simple commands | 13:55 |
| pavelpachkovskij | you have to ssh to it, go to root folder, su as a deploy user, and only then run your command | 13:55 |
| pavelpachkovskij | marcoceppi, becomes not simple at all | 13:55 |
| marcoceppi | pavelpachkovskij: it does, I mean there are other ways around that, like writing convience scrips (imagine just doing `juju ssh 2 run "rake db:migrate"` where run would cd to proper folder, su to user, wrap command or pass to chef solo, etc) | 13:56 |
| pavelpachkovskij | marcoceppi, I understand that it's easy for devops, but not for a casual developers | 13:56 |
| pavelpachkovskij | marcoceppi, last example makes sense | 13:58 |
| marcoceppi | pavelpachkovskij: This might be a better question for juju@lists.ubuntu.com to open a deeper dialog (and the juju-core devs typically read it) for more feedback if you're still looking for alternatives | 13:58 |
| pavelpachkovskij | marcoceppi, I have to think about this | 13:59 |
| jcastro | stokachu: I can syndicate your blog post on juju.ubuntu.com | 14:00 |
| jcastro | stokachu: but feel free to also post it to the list! | 14:00 |
| stokachu | jcastro: cool, do i need to just tag it with 'juju'? | 14:00 |
| stokachu | and i can post to the mailing list as well | 14:00 |

| pavelpachkovskij | marcoceppi, I think using juju ssh 1 run should work for my goals | 14:46 |

| jcastro | copy and paste that into an email, the +1 parts | 16:40 |
| jcastro | and then change things you don't do in the charm to +0 | 16:40 |
| jcastro | and I'll go ahead and enter it in the webform. | 16:40 |
| jamespage | jcastro, how do I tell which providers it works on? | 16:41 |
| jcastro | skip that part | 16:41 |
| jcastro | that's automatic | 16:41 |
| jcastro | skip all of reliable actually | 16:41 |
| jcastro | jamespage: got it, thank you sir! | 16:44 |
| jcastro | adam_g: we just need cinder and glance and then we're all set for OSCON! | 16:44 |
| jcastro | negronjl: mira, when you do liferay can you rate it? | 17:42 |
| jcastro | negronjl: also if you can't do it today lmk, I'm on an OSCON schedule so I can whine to someone else to finish it off | 17:42 |

| sidnei | hazmat: https://code.launchpad.net/~ubuntuone-pqm-team/juju-deployer/refactor/+merge/174877 | 22:05 |
| marcoceppi | hazmat: I've got a question about deployer | 22:41 |
| sidnei | marcoceppi: ask, maybe i can answer | 22:42 |
| marcoceppi | If I have two ambiguous relations/interfaces, how would I map that? Can I do "mysql:db": { 'consumes': ['wordpress:db'] } in the relations object? | 22:42 |
| marcoceppi | The examples show "mysql": { 'consumes': ['wordpress:db'] } but none show if you can map the relation at the top key level | 22:43 |
| sidnei | marcoceppi: both mysql:db": { 'consumes': ['wordpress:db']} and wordpress:db": { 'consumes': ['mysql:db']} would work | 22:43 |
| marcoceppi | sidnei: awesome, that makes life a little easier | 22:43 |
| hazmat | sidnei, marcoceppi the consumes/weights syntax is quite ugly.. .. i'd try.. - ["mysql:db", "wordpress:db"] | 22:55 |
| hazmat | imo | 22:55 |
| marcoceppi | hazmat: wait, so I won't have to use weights? | 22:55 |
| sidnei | yes, there's that too | 22:55 |
| marcoceppi | I can just have a list of relations? | 22:55 |
| hazmat | marcoceppi, yeah.. that's legacy format.. i added some simpler ones.. | 22:55 |
| sidnei | marcoceppi: weights are optional (or should be) | 22:55 |
| hazmat | sidnei, there not optional in the dict format.. | 22:55 |
| marcoceppi | hazmat: can you expand just ever so slightly on your example? | 22:55 |
| * hazmat digs up a link | 22:56 | |
| sidnei | hazmat: maybe it's in my branch only? i don't have weights in any of my configs | 22:56 |
| hazmat | marcoceppi, http://bazaar.launchpad.net/~hazmat/juju-deployer/refactor/view/head:/doc/config.rst#L61 | 22:56 |
| marcoceppi | hazmat: so I should start using yaml instead of json for the deployer cfg? | 22:57 |
| hazmat | marcoceppi, i do | 22:57 |
| hazmat | much less typing | 22:57 |
| hazmat | sidnei, dunno.. perhaps they were optional keys on a dsu sort, but for legacy format, the relations struct was a dict, and it used weight as a sort key | 22:57 |
| marcoceppi | fantastic. Has this landed in "darwin" branch yet? | 22:58 |
| marcoceppi | jk, this is the darwin branch | 22:58 |
| marcoceppi | Okay, moving on. thanks for the clarification! | 22:58 |
| sidnei | hazmat: im pretty sure i sent an mp to make weight optional, default to None for the sort. | 22:58 |
| hazmat | sidnei, cool | 22:59 |
| sidnei | to the legacy deployer that is | 22:59 |
| hazmat | marcoceppi, hopefully that series distinction goes away this week, going to chat with adam_g post vacation about merging the two | 22:59 |
| marcoceppi | hazmat: that's make my life easier | 22:59 |
| sidnei | hazmat: did you fix that issue with things ending up in non-started state not causing deployer to exit non-zero? | 23:00 |
| hazmat | sidnei, is there a bug for it? i did fix a minor that deployer wasn't checking state after it did a relation wait | 23:01 |
