k3s - Ansible setup

By default this role will install a single node cluster on the provided server. The resulting cluster will also have Traefik and CoreDNS preinstalled.

Multi Node

When writing this, k3s does not support multiple masters. It does however support multiple workers. To setup a cluster with multiple workers you will need to do the following:

• Run the role on the master server. You will have to provide the following variables:
  • k3s_master: Needs to be set to true.
  • k3s_cluster_secret: A random secret that will be used to authenticate the nodes between each other.
• Then the role on the worker server. You will have to provide the following variables:
  • k3s_master: Needs to be set to false.
  • k3s_cluster_secret: The same secret as before.
  • k3s_master_ip: The IP of the master node.
