1. Set Up an OIDC Identity Provider in AWS
Create an OIDC Identity Provider in AWS IAM:
Navigate to the IAM section in the AWS Management Console.
Choose "Identity Providers," then "Create Provider."
Select "OpenID Connect" as the provider type.
For the provider URL, you need the OIDC discovery endpoint URL from your k3s cluster. This URL is typically obtained from your Kubernetes cluster's API server configuration.
Add the thumbprint of the OIDC provider's SSL certificate.

2. Configure k3s for OIDC
Configure k3s with OIDC Details:

  local ip = ""
  local success, socket = pcall(require, "socket")
  if success then
    ip = socket.dns.toip(hostname)
  end
  print(ip, success, socket)
  return ip
end

Some notes from engineering.

1) Identify the partition

Mnesia('rabbit@juju-machine-30-lxd-11'): ** ERROR ** mnesia_event got {inconsistent_database, running_partitioned_network, 'rabbit@juju-machine-29-lxd-9'}

$ sudo rabbitmqctl cluster_status

2) Pick the most reliable node as the master.
