Clean Up Your Room! What Does It Mean to Delete Something in K8s
Talkat KubeCon + CloudNativeCon North America 2020 Virtual · on Tuesday, 2020-11-17· at 13:50· Intrado Virtual Event Platform,·
summary
Explains how Kubernetes actually deletes resources by walking examples using kubectl create/get/patch/delete, kubectl proxy and curl to the API, showing deletionTimestamp behavior and how adding a finalizers string blocks removal until the finalizer is cleared (patch to remove it completes the delete). Shows ownerReferences causing cascade deletes or orphaning (delete with cascade=false removes ownerRef but leaves children), and how to set propagationPolicy via raw API to choose foreground, background, or orphan semantics; includes forcing namespace finalization.
