Installing OpenShift Pipelines

Prerequisites

  • You have access to an OpenShift Container Platform cluster using an account with cluster-admin permissions.

  • You have installed oc CLI.

  • You have installed OpenShift Pipelines (tkn) CLI on your local system.

Installing the OpenShift Pipelines Operator in web console

You can install OpenShift Pipelines using the Operator listed in the OpenShift Container Platform OperatorHub. When you install the OpenShift Pipelines Operator, the Custom Resources (CRs) required for the Pipelines configuration are automatically installed along with the Operator.

Procedure

  1. In the Administrator perspective of the web console, navigate to Operators → OperatorHub.

  2. Use the Filter by keyword box to search for OpenShift Pipelines Operator in the catalog. Click the OpenShift Pipelines Operator tile.

    Ensure that you do not select the Community version of the OpenShift Pipelines Operator.

  3. Read the brief description about the Operator on the OpenShift Pipelines Operator page. Click Install.

  4. On the Create Operator Subscription page:

    1. Select All namespaces on the cluster (default) for the Installation Mode. This mode installs the Operator in the default openshift-operators namespace, which enables the Operator to watch and be made available to all namespaces in the cluster.

    2. Select Automatic for the Approval Strategy. This ensures that the future upgrades to the Operator are handled automatically by the Operator Lifecycle Manager (OLM). If you select the Manual approval strategy, OLM creates an update request. As a cluster administrator, you must then manually approve the OLM update request to update the Operator to the new version.

    3. Select an Update Channel.

      • The ocp-<4.x> channel enables installation of the latest stable release of the OpenShift Pipelines Operator.

      • The preview channel enables installation of the latest preview version of the OpenShift Pipelines Operator, which may contain features that are not yet available from the 4.x update channel.

  5. Click Subscribe. You will see the Operator listed on the Installed Operators page.

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

  6. Verify that the Status is set to Succeeded Up to date to confirm successful installation of OpenShift Pipelines Operator.

Installing the OpenShift Pipelines Operator using the CLI

You can install OpenShift Pipelines Operator from the OperatorHub using the CLI.

Procedure

  1. Create a Subscription object YAML file to subscribe a namespace to the OpenShift Pipelines Operator, for example, sub.yaml:

    Example Subscription
    apiVersion: operators.coreos.com/v1alpha1
kind: Subscription
metadata:
  name: openshift-pipelines-operator
  namespace: openshift-operators
spec:
  channel:  <channel name> (1)
  name: openshift-pipelines-operator-rh (2)
  source: redhat-operators (3)
  sourceNamespace: openshift-marketplace (4)
    1 Specify the channel name from where you want to subscribe the Operator
    2 Name of the Operator to subscribe to.
    3 Name of the CatalogSource that provides the Operator.
    4 Namespace of the CatalogSource. Use openshift-marketplace for the default OperatorHub CatalogSources.

  2. Create the Subscription object:

    $ oc apply -f sub.yaml

    The OpenShift Pipelines Operator is now installed in the default target namespace openshift-operators.
