| anotheral | question: what do I need to do to get cloud-init to reload the ubuntu user's authorized keys from AWS metadata, when i'm creating a new AMI? | 00:43 |

| harlowja | anotheral typically clearing out the cloud-init data folder should do it | 17:53 |
| harlowja | http://cloudinit.readthedocs.org/en/latest/topics/dir_layout.html | 17:53 |
| harlowja | if u are making a new AMI i would also do other cleanup to | 17:53 |
| harlowja | cleaning out any other settings (your own ssh keys that were installed...) | 17:54 |
| anotheral | yeah it's very weird - i'm starting with an official ubuntu 12.04 daily AMI | 18:41 |
| anotheral | instantiate it, clear out /var/lib/cloud and ~ubuntu/.ssh/authorized_keys | 18:41 |
| anotheral | and make a new AMI. the authorized_keys file remains empty when I instantiate the new AMI | 18:41 |
| harlowja | hmmm | 18:47 |
| harlowja | seems odd, that shouldn't happen | 18:47 |
| harlowja | do u have the cloud-init log files from when u make a new instance from your new AMI? | 18:47 |
| anotheral | lemme check those | 18:51 |
| broskos | I'm using cloud-init with a chef block to install and run chef. How can I notify cfn or heat when the chef run has completed? Is there a way to do this with cloud-init? | 19:20 |
| harlowja | broskos i thought the heat folks had some callback mechanism? perhaps asking in #heat channel ? | 19:35 |
| broskos | harlowja: thanks, I'll try. | 19:42 |
| broskos | I see their waithandles and such, and cfn-signal which is pretty straight forward. Just working on sorting out how to tell when the chef run is finished at the moment | 19:43 |
| harlowja | ya, i know one way cloud-init can do it, but i thought the heat folks used a different strategy | 19:44 |
| harlowja | aka, http://cloudinit.readthedocs.org/en/latest/topics/examples.html#call-a-url-when-finished is one way, but i didn't think this was the way | 19:44 |
| harlowja | that more of signals when cloud-init is done, which could be used to also say 'chef' is done | 19:44 |
| broskos | saw that thanks. | 19:44 |
| broskos | can't seem to get it to send the right bits back to heat | 19:45 |
| harlowja | let me know if u find out, i've always wondered how to and never had enough time to investigate | 19:45 |
| broskos | still poking - I'll come up with somehting... I just mostly wanted to make sure I wasn't overlooking something more obvious | 19:45 |
| harlowja | broskos u might be interested in https://code.launchpad.net/~harlowja/cloud-init/better-chef-module/+merge/238040 which yahoo is using (until that merges) | 19:46 |
| broskos | k | 19:46 |
| harlowja | adds more configurability... | 19:46 |
| broskos | heh - had to hack in a small portion of that myself. | 19:53 |
| broskos | current version doesn't run chef-client except on a gem install | 19:54 |
| broskos | I'll keep an eye on that branch, it's much better than what Ive got going | 19:54 |
| harlowja | :) | 20:15 |

| broskos | harlowja: ok - from within heat you create your wait_condition and your wait_handle | 21:07 |
| broskos | like this guy does here: | 21:07 |
| broskos | https://developer.rackspace.com/blog/openstack-orchestration-in-depth-part-2-single-instance-deployments/ | 21:08 |
| broskos | very basic, name them what you will | 21:08 |
| harlowja | k, then heat just polls until that stuff is done? | 21:08 |
| broskos | the wait_handle when you reference it will return a url that you can post to | 21:08 |
| broskos | so now you can use phone_home | 21:08 |
| harlowja | ah | 21:08 |
| broskos | phone_home: url: Ref: "GoServerWaitHandle" post: [ instance_id ] | 21:08 |
| broskos | you can also daisy chain config blocks and user data together via mulipart mime | 21:09 |
| broskos | and they will process sequentially, | 21:09 |
| broskos | so chef config first, then one that does a notfiy back using heat stuff... | 21:09 |
| harlowja | right | 21:10 |
| broskos | but that is more complicated than what I needed, since I only wanted the chef config to notify | 21:10 |
| harlowja | not many people know about that mime multipart stuff, the heat folks do, ha | 21:10 |
| broskos | I found it confusing, mostly because there are 3 different template formats and various posts will have used a format slightly different that what you are using causing a lot of time interpreting and converting | 21:11 |
| harlowja | ya :-/ | 21:11 |
| broskos | in the end I got the multipart mime to work, but then backed it out and when back to phone_home | 21:12 |
