Option to change k8s service name of mongodb replicaset

MongoDB Percona Operator for MongoDB
1

Hi there,

we’re currently experimenting a little with the percona mongodb-server and the mongodb operator in on of our environments.
As we want to migrate from another mongodb replicaset, which is also exposed by a k8s service, it would be good if we could change the service name of the percona mongodb-server to something else within the helm chart. Currently the service will be deployed named as mongodb-psmdb-db-rs0.

Hello @bennedikt.wagner - can you please explain the reasoning here?
Right now Service resources are created using the cluster name as the base - <CLUSTER_NAME>-<REPLICA_SET>.

I think we can allow users to tweak it, but not sure about the use case here.

Hey Sergey thanks for your quick response !

In our case, one reason is that we send the service name through several external services. Another servicename would lead to a lot of changes for us. Therefore, it would be easier to configure the servicename itself to the previous one.

Got it. Yeah, for now it is not possible to configure it that way.

As a workaround you can create a service manually and maintain it, but that is not really an operator way.

I created this ticket: [K8SPSMDB-889] Support Custom Service names - Percona JIRA

Also we will monitor the upvoting in our public roadmap: [K8SPSMDB-889] Support Custom Service names · Issue #87 · percona/roadmap · GitHub

any update on this as it is a blocker for our mongodb setup

Exactly … you should use different namespaces instead. Totally transparent …
