Installing OpenShift Pipelines

This guide walks cluster administrators through the process of installing the Red Hat OpenShift Pipelines Operator to an OpenShift Container Platform cluster.

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.

  • Your cluster has the Marketplace capability enabled or the Red Hat Operator catalog source configured manually.

In a cluster with both Windows and Linux nodes, Red Hat OpenShift Pipelines can run on only Linux nodes.

Installing the Red Hat OpenShift Pipelines Operator in web console

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

The default Operator custom resource definition (CRD) config.operator.tekton.dev is now replaced by tektonconfigs.operator.tekton.dev. In addition, the Operator provides the following additional CRDs to individually manage OpenShift Pipelines components: tektonpipelines.operator.tekton.dev, tektontriggers.operator.tekton.dev and tektonaddons.operator.tekton.dev.

If you have OpenShift Pipelines already installed on your cluster, the existing installation is seamlessly upgraded. The Operator will replace the instance of config.operator.tekton.dev on your cluster with an instance of tektonconfigs.operator.tekton.dev and additional objects of the other CRDs as necessary.

If you manually changed your existing installation, such as, changing the target namespace in the config.operator.tekton.dev CRD instance by making changes to the resource name - cluster field, then the upgrade path is not smooth. In such cases, the recommended workflow is to uninstall your installation and reinstall the Red Hat OpenShift Pipelines Operator.

The Red Hat OpenShift Pipelines Operator now provides the option to choose the components that you want to install by specifying profiles as part of the TektonConfig custom resource (CR). The TektonConfig CR is automatically installed when the Operator is installed. The supported profiles are:

  • Lite: This installs only Tekton Pipelines.

  • Basic: This installs Tekton Pipelines, Tekton Triggers, and Tekton Chains.

  • All: This is the default profile used when the TektonConfig CR is installed. This profile installs all of the Tekton components, including Tekton Pipelines, Tekton Triggers, Tekton Chains, Pipelines as Code, and Tekton Addons. Tekton Addons includes the ClusterTasks, ClusterTriggerBindings, ConsoleCLIDownload, ConsoleQuickStart, and ConsoleYAMLSample resources, as well as the tasks available using the cluster resolver from the openshift-pipelines namespace.

Procedure

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

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

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

  4. On the Install Operator 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 latest channel enables installation of the most recent stable version of the Red Hat OpenShift Pipelines Operator. Currently, it is the default channel for installing the Red Hat OpenShift Pipelines Operator.

      • To install a specific version of the Red Hat OpenShift Pipelines Operator, cluster administrators can use the corresponding pipelines-<version> channel. For example, to install the Red Hat OpenShift Pipelines Operator version 1.8.x, you can use the pipelines-1.8 channel.

        Starting with OpenShift Container Platform 4.11, the preview and stable channels for installing and upgrading the Red Hat OpenShift Pipelines Operator are not available. However, in OpenShift Container Platform 4.10 and earlier versions, you can use the preview and stable channels for installing and upgrading the Operator.

  5. Click Install. 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 Red Hat OpenShift Pipelines Operator.

    The success status may show as Succeeded Up to date even if installation of other components is in-progress. Therefore, it is important to verify the installation manually in the terminal.

  7. Verify that all components of the Red Hat OpenShift Pipelines Operator were installed successfully. Login to the cluster on the terminal, and run the following command:

    $ oc get tektonconfig config
    Example output
    NAME     VERSION   READY   REASON
config   1.15.0     True

    If the READY condition is True, the Operator and its components have been installed successfully.

    Additonally, check the components' versions by running the following command:

    $ oc get tektonpipeline,tektontrigger,tektonchain,tektonaddon,pac
    Example output
    NAME                                          VERSION   READY   REASON
tektonpipeline.operator.tekton.dev/pipeline   v0.47.0   True

NAME                                        VERSION   READY   REASON
tektontrigger.operator.tekton.dev/trigger   v0.23.1   True

NAME                                    VERSION   READY   REASON
tektonchain.operator.tekton.dev/chain   v0.16.0   True

NAME                                    VERSION   READY   REASON
tektonaddon.operator.tekton.dev/addon   1.11.0     True

NAME                                                             VERSION   READY   REASON
openshiftpipelinesascode.operator.tekton.dev/pipelines-as-code   v0.19.0   True

Installing the OpenShift Pipelines Operator using the CLI

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

Procedure

  1. Create a Subscription object YAML file to subscribe a namespace to the Red Hat 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 The channel name of the Operator. The pipelines-<version> channel is the default channel. For example, the default channel for Red Hat OpenShift Pipelines Operator version 1.7 is pipelines-1.7. The latest channel enables installation of the most recent stable version of the Red Hat OpenShift Pipelines 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 subscription installs the Red Hat OpenShift Pipelines Operator into the openshift-operators namespace. The Operator automatically installs OpenShift Pipelines into the default openshift-pipelines target namespace.

Red Hat OpenShift Pipelines Operator in a restricted environment

The Red Hat OpenShift Pipelines Operator enables support for installation of pipelines in a restricted network environment.

The Operator installs a proxy webhook that sets the proxy environment variables in the containers of the pod created by tekton-controllers based on the cluster proxy object. It also sets the proxy environment variables in the TektonPipelines, TektonTriggers, Controllers, Webhooks, and Operator Proxy Webhook resources.

By default, the proxy webhook is disabled for the openshift-pipelines namespace. To disable it for any other namespace, you can add the operator.tekton.dev/disable-proxy: true label to the namespace object.
