Two types of garbage collection are performed on an OpenShift Container Platform node: • Container garbage collection: Removes terminated containers. • Image garbage collection: Removes images not referenced by any running pods. Container garbage collection can be performed using eviction thresholds. Image garbage collection relies on disk usage as reported by cAdvisor on the node to decide which images to remove from the node.
