<p>Do sporadic disk cleanup operations happen automatically in Kubernetes or should this be a scheduled "docker RM/RMI" to remove discarded images?  A single node in my dev K8s cluster (other nodes are fine) keeps running out of disk space in / and the following message is show in the K8s UI events:</p>

<p>reason: freeDiskSpaceFailed</p>

<p>Message: failed to garbage collect required amount of images. Wanted to free 2069743207, but freed 0</p>

<p>Yes,Kubernetes supports container and image garbage collection. More details in <a href="https://kubernetes.io/docs/concepts/cluster-administration/kubelet-garbage-collection/" rel="nofollow noreferrer">https://kubernetes.io/docs/concepts/cluster-administration/kubelet-garbage-collection/</a></p>

<p>You may want to check whether that particular node has enough disk space allocated to host the images for the pods assigned to it.</p>
