Hi, you can't do that with Cellar (again, Cellar is active/active).
For "pure" failover, you have to use the lock mechanism. Your two docker processes should: 1. use a shared filesystem (like NFS) to store the lock 2. a database lock Kubernetes POD could be used with Cellar to discover the cluster nodes, but not for failover.
