Re: Spark driver pod garbage collection

[Anirudh Ramanathan]

There's a flag to the controller manager that is in charge of retention
policy for terminated or completed pods.

https://kubernetes.io/docs/reference/command-line-tools-reference/kube-controller-manager/#options
--terminated-pod-gc-threshold int32 Default: 12500
Number of terminated pods that can exist before the terminated pod garbage
collector starts deleting terminated pods. If <= 0, the terminated pod
garbage collector is disabled.

Spark driver pod garbage collection

[purna pradeep]

Hello,

Currently I observe dead pods are not getting garbage collected (aka spark
driver pods which have completed execution). So pods could sit in the
namespace for weeks potentially. This makes listing, parsing, and reading
pods slower and well as having junk sit on the cluster.

I believe minimum-container-ttl-duration kubelet flag is by default set to
0 minute but I don’t see the completed spark driver pods are garbage
collected

Do I need to set any flag explicitly @ kubelet level?
