Consul 1.4 introduces Cloud auto-join, which finds the
IP addresses of the other nodes by querying an API (in
that case, the Kubernetes API).
This involves creating a service account and granting
permissions to list and get pods. It is a little bit
more complex, but it reuses previous notions (like RBAC)
so I like it better.
- explain the reason why we have stateful sets
- explain the relationship between volumes, persistent volumes,
persistent volume claims, volume claim templates
- show how to run a Consul cluster with a stateful set
