03/06/2023, 7:46 PMThe K3s apiserver is the same as the Kubernetes apiserver. Anything covered in the docs here is true in k3s:

03/06/2023, 7:48 PMThe question is probably, how are you linking the two resources together, and how are you expecting them to be cleaned up. do you need a finalizer? are you expecting Kubernetes to handle it for you? What fields are you using to track the relationships?

03/06/2023, 7:50 PMActually, the thing is that on my local kubernetes cluster, garbage collection works correctly, but in k3s, after I delete the primary resource, the secondary resource still exists.
I believe this might be due to way how k3s is provisioned - I am using java test containers to provision k3s cluster

03/06/2023, 7:51 PMCan you suggest where to look for logs? What to debug to find the issue?

03/06/2023, 7:53 PMwhat kind of resources are we talking about
r

03/06/2023, 7:54 PMare these custom resources? core resources that the controller-manager is responsible for? Can you answer any of the questions above about how the relationships are tracked?

03/06/2023, 7:56 PMWith regards to garbage collection, there’s nothing unique to our apiserver or controller-manager compared to a “vanilla” Kubernetes cluster.

03/06/2023, 8:01 PMWeird, I think that 5 seconds is not enough to garbage collect resources 🤔
This was the timeout that I set, and after waiting for more time period, I see that the resource was deleted 😛

03/06/2023, 8:02 PMAnswering your questions - I use owner references, secondary resource references primary resource using owner reference

03/06/2023, 8:04 PMI wonder if it is possible to override poll interval (?) in k3s, so the resources would be cleaned faster?

03/06/2023, 8:25 PMI’m not sure. There’s probably a tunable somewhere but that’s not something I’ve ever needed to mess with.

03/06/2023, 8:34 PMok, thanks for that. I’ll switch to checking that the resource does not exist OR it was marked for deletion. This should do the job, thanks! 🙂
