User Management

User Management (an explanation)

We use a chef cookbook named chef-user, which is way for you to specify how users are created. The first job start has is to create json files contain information about the host and pair users. These files are read by chef-user and used to create users on your EC2 instance.

It does the following for each user specified:

• uses adduser to build the user
• builds their .ssh file and changes ownership to that user
• adds all of their public SSH keys to the ~/.ssh/authorized_keys file (via GitHub's API)

We also create a pairing user which we'll use to connect the two users over TMUX. We create this third user in order to ensure that the user that owns the TMUX session doesn't have sudo.
