etcd Cluster fails to start

Hi guys, thank you for your effort. I've tried diving into this following the example, however, my etcd cluster fails to start.

First it looks like this

kubectl -n default get pods
NAME                              READY     STATUS     RESTARTS   AGE
etcd-operator-779446c7d8-t2hm9    3/3       Running    0          28m
example-etcd-f4rhsm64d4           0/1       Init:0/1   0          9s
vault-operator-7dc8b55b4d-mkz5p   1/1       Running    0          28m

Then it errors out, without providing any output:

 nvarz:~/playground/vault-operator (master *%=)$ kubectl -n default get pods -w
NAME                              READY     STATUS    RESTARTS   AGE
