Rackspace OpenStack image

[MarZab]

It took me the better part of the last 2 days to figure all this out - so I'm writing it down for the next poor soul who goes my path (me included) before this will be cleaned up.

Build the image

• clone this repo to a folder https://github.com/octohost/ubuntu-14.04 export SDK_ ... build_openstack

  This step will spin up a instance on rackspace, make a image then save it, then destroy the server. Get the ID from the image it made, we'll need that now.

• clone this repo follow octohost::default replace source_image inside template.json with the ID mentioned before export SDK_ ... build_openstack

  This step will use the image it constructed before for a base in a similar process then before, making a server, building the image, saving the image then destroying the server. Yay this means you now have a image you can spin up with your own configuration.

  Install the server in one node mode

  You might want to scale on later, but for now, lets have one server.

• Follow the instructions here: https://www.octohost.io/theory-of-operation.html

• It works up to step 3, when you push, you get these errors:

  • perl: warning: Setting locale failed.

  Login, run this, then logout/login again. sudo locale-gen en_US en_US.UTF-8 dpkg-reconfigure locales

  • remote: parse error: Invalid numeric literal at line 1, column 3 This one is a doozy, it might look innocent enough but it is actually a symptom of Consul not working Other symptoms are:
  • the same error when running octo status
  • remote: 2015/06/04 11:48:43 [ERR] (view) "key(octohost/sample/DOMAINS)" store key: error fetching: Unexpected response code: 500

  The problem here is actually 2015/06/04 12:58:27 [INFO] raft: Disabling EnableSingleNode (bootstrap) ie. Consul is excpecting more nodes and it wont startup before it has 2 more Stop Consul, remove the old data and restart: service consul stop mv /var/cache/octohost /var/cache/octohost-old mkdir /var/cache/octohost service consul start

  Now listen to the log to see it successfully started: consul monitor

• octo restart [] will not help you start the service, you need to push the git repo again, YAY DONE

Thanks for the detailed list. I will take a look and see where I can improve the documentation and the cookbooks.

Unfortunately since we can't share images on Rackspace it makes it more complex than it should be. Maybe I can just use a standard Ubuntu 14.04 image in the JSON so that it cuts out a few steps.

I'll also add a command to clear out Consul to make that easier.

also https://github.com/octohost/octohost-cookbook/blob/master/files/default/consulkv could have some error checking, giving out a json error was making me go in loops trying to find the source of the error :)

Thanks a bunch for this awesome project, il be sure to contribute as much as I can.

OK - so I think I've fixed many of the problems listed here:

1. Use a public image for the base - so it should work automatically now - you won't get that error anymore and you don't have to do anything with the octohost/ubuntu-14.04 repo now.
2. Make sure to remove Consul's state at the end of the install - so it should start up easier and cleaner.

I'm going to look and see if I can get Terraform going with Openstack/Rackspace now as well.

OK - now there's a set of Terraform files for Rackspace - it clears out Consul and gets it all running:

https://github.com/octohost/octohost-cookbook/commit/beac71a

All you should have to do is:

cp variables.dist variables.tf
terraform apply
cat ~/.ssh/id_dsa.pub | ssh root@ip.add.res.here "sudo gitreceive upload-key name"

Let me know if you've got any questions or concerns. Likely if you're not using North American endpoints some of that may have to change - but it worked in IAD for me.
