Chapter 2. Uninstalling OpenShift Pipelines

Cluster administrators can uninstall the Red Hat OpenShift Pipelines Operator by performing the following steps:

  1. Delete the Custom Resources (CRs) for the optional components, TektonHub and TektonResult, if these CRs exist, and then delete the TektonConfig CR.

    Caution

    If you uninstall the Operator without removing the CRs of optional components, you cannot remove the components later.

  2. Uninstall the Red Hat OpenShift Pipelines Operator.
  3. Delete the Custom Resource Definitions (CRDs) of the operator.tekton.dev group.

Uninstalling only the Operator will not remove the Red Hat OpenShift Pipelines components created by default when the Operator is installed.

2.1. Deleting the OpenShift Pipelines Custom Resources

If the Custom Resources (CRs) for the optional components, TektonHub and TektonResult, exist, delete these CRs. Then delete the TektonConfig CR.

  2. Type TektonHub in the Filter by name field to search for the TektonHub Custom Resource Definition (CRD).
  3. Click the name of the TektonHub CRD to display the details page for the CRD.
  4. Click the Instances tab.
  5. If an instance is displayed, click the Options menu kebab for the displayed instance.
  6. Select Delete TektonHub.
  7. Click Delete to confirm the deletion of the CR.
  8. Repeat these steps, searching for TektonResult and then TektonConfig in the Filter by name box. If any instances are found for these CRDs, delete these instances.
Note

Deleting the CRs also deletes the Red Hat OpenShift Pipelines components and all the tasks and pipelines on the cluster.

Important

If you uninstall the Operator without removing the TektonHub and TektonResult CRs, you cannot remove the Tekton Hub and Tekton Results components later.
