Thunix Ansible Playbook

Clone repo, then execute playbook as follows:

/usr/local/bin/ansible-playbook -i /var/thunix/hosts /var/thunix/site.yml

Intro

If you're wondering what this repo is, it's a set of files (YAML files) that are executed by a package known as "Ansible".

Docs for how these files are structured to be used can be found here.

There are three roles currently being used: common, webservers, and shell. Pretty straightfoward, common applies to all machines in the inventory. webservers applies to the summit box. shell is for the phoenix box.

So, when you need to add a user, get a package installed, etc etc, please keep the above in mind, and do your changes in the correct role.

  • TODO - Maybe rename roles to boxes? Dunno yet.

Common tasks

Adding a user

To add a user to thunix, just copy one of the files in ./roles/shell/tasks/users to a new file in that same directory. Edit the file, changing the applicable info (user name, keys, homedir, etc etc etc). Then, add that file's path to ./roles/shells/tasks/users.yml. Run a syntax check:

ansible-playbook -i ./hosts site.yml --syntax

This should just return an "OK" if it looks good (Syntactically). Doesn't test the logic though!

After that, run it again, without the syntax flag:

ansible-playbook -i ./hosts site.yml

If it looks good, add all your files, then push to the repo.

If for whatever reason you can't do this, create a PR and let our CI (Drone) test it for you.

Adding a Package

To install a new package on a machine, just find the package name, and add it to the end of ./role/{which role}/tasks/packages.yml. Run ansible-playbook against thunix:

ansible-playbook -i ./hosts site.yml

Don't

  • Don't commit right to master. Create a git branch, commit changes there, and do a test run of ansible against it. Master runs automatically as soon as you push, and we never want master in a broken state.
  • Don't be afraid to make a PR! Worst case, the PR is rejected. That's fine, nobody will be offended. What will likely happen is it'll be merged in if it doesn't break master. It might get tweaked a bit, but that's all.
  • If you have a problem/request, and don't know how to make it happen, open a ticket. Even if you know how to fix it, open a ticket, to link to your PR. It makes a good place to discuss proposed changes.
  • ASK! If you have a question/concern, feel free to ask in IRC.
