Creating new Cluster

  1. Provision individual machine with Debian
    • Ensure that the root user can be logged into using the SSH key
    • Change the hostname to match the naming scheme (s{n}-{cluster})
    • Install, start and enable Tailscale on each node
  2. Create a new folder in inventory named {cluster}, add the group_vars and hosts.ini file. Refer to each machine using the hostname
  3. Run the site.yml on the cluster to initialize the initial state

Running a single playbook on the cluster

This is done via Github Actions. The action will connect to the cluster with Ephemeral Key (this will expire one day, make sure to update). Then run it by providing the cluster name, and the playbook name to run (include the _ in the name, but exclude the .yml extension)
