This is regarding OCP 3.11.

I have a lot of containers with status 'Exited' piling up and as a result of that I'm seeing disk pressure on the worker nodes.

I was looking for ways of removing these containers and came across the garbage collection mechanism, however as per Kubernetes' documentation the flags that OpenShift doc suggests to use are deprecated.

Here is the OpenShift doc on garbage collection: https://access.redhat.com/documentation/en-us/openshift_container_platform/3.11/html/cluster_administration/admin-guide-garbage-collection

Here is the doc where it says those options are deprecated: https://v1-11.docs.kubernetes.io/docs/tasks/administer-cluster/out-of-resource/

That got me confused. Does the maximum-dead-containers option still work under OpenShift or am I supposed to use the eviction policy?

I was also thinking of using this docker command via either crontab or Prometheus executor: docker ps -aq --no-trunc -f status=exited | xargs docker rm"

Unfortunately, I don't have a test environment to test this.
I'd be grateful for any suggestions.
