Setting custom name for Replica Set Config Server

MongoDB Percona Operator for MongoDB

How to set a custom name for Replica Set Config Server?
The default is “cfg”
I tried this option, but it did not work.

  sharding:
    enabled: true
    configsvrReplSet:
      size: 3
      configuration: |
        replication:
          replSetName: myCustomName

Is this not possible at all as noted here?

I would like to migrate the existing selfhosted Mongodb to Kubernetes and try to use this procedure:

The config replica set name on the source MongoDB is not “cfg”.
Is renaming the config replica set to “cfg” on the source MongoDB the only way to do this?

Hi @kamuna !
I believe currently it is not possible with the procedure you linked. What comes into mind is maybe doing a logical backup then renaming the replica inside it, but that could be messy even if possible.

I would encourage you to open a Jira ticket here: https://jira.percona.com/ under project: K8SPSMDB and describe your use case so it will be considered for some future release (from what I see it should not be hard to implement).
