Change default server pool size to 1

Nice procject :)

I would suggest changing the default size of the server pool to 1 as there is no advantage to having an even number of etcd nodes.

Interesting, 3 worker nodes would be handy.

Is it as simple as setting k3s_server_pool_size to 1, and k3s_worker_pool_size to 3?

It should be as simple, yes.

Of course, having only a single control plane node means no high availability, but so does having two, because one node being down equals loss of quorum. Usually, non-HA control plane is fine for hobby purposes.

Hi @sphr2k yes you are right 👍 I will reduce the number of server from 2 to 1 and i will try to add an extra instance to the worker with oci_core_instance_pool_instance resource. But @mannp is not possible to set k3s_worker_pool_size to 3 with a free account (no problem with paid account)
