Thanks @johscheuer!

I have a related question: I am creating a cluster using the faultDomain as described here. I copy/pasted that block in my FDB definition, even if documentation mentions that it is the default and thus should be unnecessary.

However pods are still getting scheduled on same nodes, and I do not see any topology spread / pod anti-affinity being generated in the pod YAML definitions created by the operator. I also tried to find references to this configuration in the codebase of the operator, but I can't find anything related to the default as mentioned there 🤔 instead I see plenty of checks for the key foundationdb.org/kubernetes-cluster.

Do you have any pointers for me to understand better how the fault domain feature works, or perhaps existing E2E tests covering this?

[johscheuer]

Could you create an issue or a forum post for that? Tracking all the comments/question in unrelated PR's makes it harder for me to make sure I answered your questions.

The best is to always produce a minimal reproducible example.

Sure, I wanted to make sure that there is a problem first, by checking the relevant code. I will try to reproduce it and then open an issue.

Figured a few things out, the issue is open here.

Thanks!
