The create a cluster when it receives an
To initialize a cluster, we first need to create a seed etcd member. Then we can rely on resize to increase the cluster size to the desired number of members.
If operator fails before creating the first member, we will end up with a cluster with no running pods.
Recovery can be challenging if this happens. It is impossible for us to differentiate a dead cluster from a uninitialized cluster.
We choose the simplest solution here. We always consider a cluster with no running pods a failed cluster. The operator will try to recover it from existing backups. If there is no backup, we mark the cluster dead.
