arango-storage Cannot set leader role on Pod

[awlayton]

I have a cluster with one master node and one worker node. When I try to create arango-storage the status gets stuck on CrashLoopBackOff (see get pods output below). Also, from the logs output it seems the problem has to do with setting one of the pods with the leader role.

Am I doing something wrong here?
