Deploying minio and milvus as statefulsets

[nairan-deshaw]

Currently, in standalone mode, the operator creates deployment for minio and milvus which leads to an issue where we do a rolling restart and the old pod still is mounted to the PVC. This creates a deadlock where the new one is not able to start and the old one does not die. Is there a way to configure these as statefulsets / change the update strategy to Recreate?

For milvus, you can explicitly set spec.components.enableRollingUpdate to false.
And for minio, I'm not very sure, but you could try setting spec.dependencies.storage.inCluster.values.DeploymentUpdate.type to Recreate

Em... There is a bug in setting spec.components.enableRollingUpdate to false. You may not be able to make the strategy to Recreate. I'll fix this later.

Is there a way to deploy these as statefulsets instead?

No for Milvus.
For minIO, if you specify the cluster mode of it, it will become a statefulset.
