  5. In the Create Operator Subscription screen, ensure that:

    • the Installation Mode selected is All namespaces on the cluster (default), as the OpenShift Pipelines operator needs to watch for Tekton Custom Resources across all namespaces.

    • the Approval Strategy is Automatic so that future upgrades to the operator are handled automatically by the the Operator Lifecycle Manager (OLM). If you select Manual; when a new version of the Operator is available, you will need to manually approve the OLM update request to update to the new version.

      OpenShift Pipelines 0.5.2 has introduced changes incompatible with older versions. If the installed version is 0.5.0 or below, the operator will not be automatically upgraded. To upgrade from the 0.5.0 or below, uninstall the operator and then install it again.

  6. Click Subscribe. You will see the operator listed on the Installed Operators page.

    The operator is installed automatically into the openshift-operators namespace.

  7. In the Subscription Overview screen, verify the installation of the operator by confirming that the UPGRADE STATUS is 1 installed.
