This document assumes you have access to IAM, and know how to do the basics with it. You will need an AWS access ID and secret key, with read-only access. Right now it'll only look at EC2 instances, so that's all it'll have read-only access to. Do not use your personal key.

Setting up the master server

First set up the PPA and install Ansible

$ sudo apt-get install software-properties-common
$ sudo apt-add-repository ppa:ansible/ansible3
$ sudo apt-get update
$ sudo apt-get install ansible

Next install pip, because we're gonna be doing Python stuff.

$ sudo apt-get install python-pip

and now boto, the AWS library for Python. We're using this to automagically get servers that are tagged with "Project: communityit". It saves us from having to manually update the hosts file every time a server scales/is created/deleted.

$ sudo pip install boto

Now, we'll make a configuration file.

Create /etc/boto.cfg, using this template:

[Credentials]
aws_access_key_id = <your_access_key_here>
aws_secret_access_key = <your_secret_key_here>

Remember, DON'T USE YOUR PERSONAL ACCESS KEYS

And now finally, we're going to clone our Ansible repo.

git clone [email protected]:Mozilla-cIT/ansible-playbooks.git /etc/ansible

And from here, the master should be set up.
