Chapter 6. Removing Service Telemetry Framework from the Red Hat OpenShift Container Platform environment

Procedure

1. Run the oc delete command:

   $ oc delete project service-telemetry

2. Verify that the resources have been deleted from the namespace:

   $ oc get all
   No resources found.

Procedure

1. Delete the Subscription from the openshift-cert-manager-operator namespace:

   $ oc delete --namespace=openshift-cert-manager-operator subscription openshift-cert-manager-operator
   
   subscription.operators.coreos.com "openshift-cert-manager-operator" deleted

2. Retrieve the version number of your installed ClusterServiceVersion:

   $ oc get --namespace=openshift-cert-manager-operator subscription openshift-cert-manager-operator -oyaml | grep currentCSV

   Example output:

     currentCSV: openshift-cert-manager.v1.7.1

3. Delete the ClusterServiceVersion from the openshift-cert-manager-operator namespace:

   $ oc delete --namespace=openshift-cert-manager-operator csv openshift-cert-manager.v1.7.1

   Example output:

   clusterserviceversion.operators.coreos.com "openshift-cert-manager.v1.7.1" deleted

4. Get the current list of CustomResourceDefinitions provided by the Operator so they can be deleted after removal of the ClusterServiceVersion:

   $ oc get csv -n openshift-cert-manager-operator openshift-cert-manager.v1.7.1 -oyaml | grep "kind: CustomResourceDefinition" -A2 | grep name | awk '{print $2}'

   Example output:

   certificaterequests.cert-manager.io
   certificates.cert-manager.io
   certmanagers.config.openshift.io
   certmanagers.operator.openshift.io
   challenges.acme.cert-manager.io
   clusterissuers.cert-manager.io
   issuers.cert-manager.io
   orders.acme.cert-manager.io

5. Delete the CustomResourceDefinitions related to the cert-manager Operator:

   $ oc delete crd certificaterequests.cert-manager.io certificates.cert-manager.io certmanagers.config.openshift.io certmanagers.operator.openshift.io challenges.acme.cert-manager.io clusterissuers.cert-manager.io issuers.cert-manager.io orders.acme.cert-manager.io

   Example output:

   customresourcedefinition.apiextensions.k8s.io "certificaterequests.cert-manager.io" deleted
   customresourcedefinition.apiextensions.k8s.io "certificates.cert-manager.io" deleted
   customresourcedefinition.apiextensions.k8s.io "certmanagers.config.openshift.io" deleted
   customresourcedefinition.apiextensions.k8s.io "certmanagers.operator.openshift.io" deleted
   customresourcedefinition.apiextensions.k8s.io "challenges.acme.cert-manager.io" deleted
   customresourcedefinition.apiextensions.k8s.io "clusterissuers.cert-manager.io" deleted
   customresourcedefinition.apiextensions.k8s.io "issuers.cert-manager.io" deleted
   customresourcedefinition.apiextensions.k8s.io "orders.acme.cert-manager.io" deleted

6. Delete the namespaces owned by the cert-manager Operator:

   $ oc delete project openshift-cert-manager openshift-cert-manager-operator

   Example output:

   project.project.openshift.io "openshift-cert-manager" deleted
   project.project.openshift.io "openshift-cert-manager-operator" deleted
