Delete OpenShift Project

Issue, can’t delete a namespace/project and is stuck in a “Terminating” status

oc delete project fishbone

oc get projects fishbone
NAME       DISPLAY NAME   STATUS
fishbone   Fishbone       Terminating

Solution

Define the namespace/project to delete

export NAMESPACE=fishbone

Cleanup the finalizers section from the namespace definition and define a json file with that

oc get namespace $NAMESPACE -o=json | jq '.spec = {"finalizers":[]}' > $NAMESPACE.json
{
  "apiVersion": "v1",
  "kind": "Namespace",
  "metadata": {
    "annotations":
      "openshift.io/description": "",
      "openshift.io/display-name": "Fishbone",
      "openshift.io/requester": "system:admin",
      "openshift.io/sa.scc.mcs": "s0:c24,c14",
      "openshift.io/sa.scc.supplemental-groups": "1000580000/10000",
      "openshift.io/sa.scc.uid-range": "1000580000/10000"
    },
    "creationTimestamp": "2021-02-20T03:29:59Z",
    "deletionTimestamp": "2021-02-20T03:31:35Z",
    "name": "fishbone",
    "resourceVersion": "270664",
    "selfLink": "/api/v1/namespaces/fishbone",
    "uid": "885c4440-6f05-4e72-a103-28e61705406f"
  },
  "spec": {
    "finalizers": [
      "kubernetes"
    ]
  },
  "status": {
    "conditions": [
        .
        .
        .
    ],
    "phase": "Terminating"
}

Apply the json file from the previous step to delete the finalizers and therefore the deletion of the namespace/project

curl -k -H "authorization: Bearer $(oc whoami --show-token)" -H "Content-Type: application/json" -X PUT --data-binary @$NAMESPACE.json $(oc whoami --show-server)/api/v1/namespaces/$NAMESPACE/finalize

Verify that the namspace/project has been deleted

oc get projects $NAMESPACE
Error from server (NotFound): namespaces "fishbone" not found
