Hey folks,

I hope you all had a great vacation 😊

Unfortunately, I am facing some issues with cascading deletion on the theia-dev cluster ([https://k8s-theia-cp.ase.cit.tum.de:6443|https://k8s-theia-cp.ase.cit.t/]). Even though the ownerReferences are set correctly, the child-resources are not deleted when the owner/parent is deleted.

I conducted some simple tests to verify the situation. Let me introduce you to the situation:

1. Installed basic deployment

{code:java}
iVersion: apps/v1
kind: Deployment
metadata:
name: nginx-deployment
spec:
replicas: 3
selector:
matchLabels:
app: nginx
template:
metadata:
labels:
app: nginx
spec:
containers:
- name: nginx
image: nginx:1.21.3
ports:
- containerPort: 80{code}

2. This creates:

• 1 Deployment nginx-deployment
• 1 ReplicaSet nginx-deployment-85484bf959 with ownerReference = deployment nginx-deployment
• 3 Pods with each ownerReference = replicaset nginx-deployment-85484bf959

All of them have "blockOwnerDeletion":true, I do not know whether this is important...

=> The setup should work for cascading deletes.

3. Delete the deployment. It is expected that the replicaset and consequently also the pods are deleted. However, this is not the case.

Please let me know If I can help you with fixing this problem. I'd also greatly appreciate a expected fix date to estimate a bit better as it's currently blocking quite a significant part of my master's thesis ☺️
Thank you so much!
