Installing and configuring OpenShift Pipelines
Abstract
Chapter 1. Installing OpenShift Pipelines Copy linkLink copied to clipboard!
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-adminpermissions. -
You have installed
ocCLI. -
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.
1.1. Installing the Red Hat OpenShift Pipelines Operator in web console Copy linkLink copied to clipboard!
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
TektonConfigCR 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 theClusterTriggerBindings,ConsoleCLIDownload,ConsoleQuickStart, andConsoleYAMLSampleresources, as well as the tasks and step actions available using the cluster resolver from theopenshift-pipelinesnamespace.
Procedure
- In the Administrator perspective of the web console, navigate to Operators → OperatorHub.
-
Use the Filter by keyword box to search for
Red Hat OpenShift PipelinesOperator in the catalog. Click the Red Hat OpenShift Pipelines Operator tile. - Read the brief description about the Operator on the Red Hat OpenShift Pipelines Operator page. Click Install.
On the Install Operator page:
-
Select All namespaces on the cluster (default) for the Installation Mode. This mode installs the Operator in the default
openshift-operatorsnamespace, which enables the Operator to watch and be made available to all namespaces in the cluster. - 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.
Select an Update Channel.
-
The
latestchannel 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 version1.8.x, you can use thepipelines-1.8channel.NoteStarting with OpenShift Container Platform 4.11, the
previewandstablechannels 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 thepreviewandstablechannels for installing and upgrading the Operator.

Click Install. You will see the Operator listed on the Installed Operators page.
NoteThe Operator is installed automatically into the
openshift-operatorsnamespace.Verify that the Status is set to Succeeded Up to date to confirm successful installation of Red Hat OpenShift Pipelines Operator.
WarningThe 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.
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:

Create the
Subscriptionobject by running the following command:oc apply -f sub.yaml
$ oc apply -f sub.yamlCopy to Clipboard Copied! Toggle word wrap Toggle overflow The subscription installs the Red Hat OpenShift Pipelines Operator into the
openshift-operatorsnamespace. The Operator automatically installs OpenShift Pipelines into the defaultopenshift-pipelinestarget namespace.
1.3. Red Hat OpenShift Pipelines Operator in a restricted environment Copy linkLink copied to clipboard!
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.
Chapter 2. Uninstalling OpenShift Pipelines Copy linkLink copied to clipboard!
Cluster administrators can uninstall the Red Hat OpenShift Pipelines Operator by performing the following steps:
Delete the Custom Resources (CRs) for the optional components,
TektonHubandTektonResult, if these CRs exist, and then delete theTektonConfigCR.ImportantIf you uninstall the Operator without removing the CRs of optional components, you cannot remove the components later.
- Uninstall the Red Hat OpenShift Pipelines Operator.
-
Delete the Custom Resource Definitions (CRDs) of the
operator.tekton.devgroup.
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 Copy linkLink copied to clipboard!
If the Custom Resources (CRs) for the optional components, TektonHub and TektonResult, exist, delete these CRs. Then delete the TektonConfig CR.

Chapter 3. Customizing configurations in the TektonConfig custom resource Copy linkLink copied to clipboard!
In Red Hat OpenShift Pipelines, you can customize the following configurations by using the TektonConfig custom resource (CR):
- Optimizing OpenShift Pipelines performance, including high-availability mode for the OpenShift Pipelines controller
- Configuring the Red Hat OpenShift Pipelines control plane
- Changing the default service account
- Disabling the service monitor
- Configuring pipeline resolvers
- Disabling pipeline templates
- Disabling the integration of Tekton Hub
- Disabling the automatic creation of RBAC resources
- Pruning of task runs and pipeline runs
3.1. Prerequisites Copy linkLink copied to clipboard!
- You have installed the Red Hat OpenShift Pipelines Operator.
3.2. Performance tuning using TektonConfig CR Copy linkLink copied to clipboard!
You can modify the fields under the .spec.pipeline.performance parameter in the TektonConfig custom resource (CR) to change high availability (HA) support and performance configuration for the OpenShift Pipelines controller.
Example TektonConfig performance fields
All fields are optional. If you set them, the Red Hat OpenShift Pipelines Operator includes most of the fields as arguments in the openshift-pipelines-controller deployment under the openshift-pipelines-controller container. The OpenShift Pipelines Operator also updates the buckets field in the config-leader-election configuration map under the openshift-pipelines namespace.
If you do not specify the values, the OpenShift Pipelines Operator does not update those fields and applies the default values for the OpenShift Pipelines controller.
If you modify or remove any of the performance fields, the OpenShift Pipelines Operator updates the openshift-pipelines-controller deployment and the config-leader-election configuration map (if the buckets field changed) and re-creates openshift-pipelines-controller pods.
High-availability (HA) mode applies to the OpenShift Pipelines controller, which creates and starts pods based on pipeline run and task run definitions. Without HA mode, a single pod executes these operations, potentially creating significant delays under a high load.
In HA mode, OpenShift Pipelines uses several pods (replicas) to execute these operations. Initially, OpenShift Pipelines assigns every controller operation into a bucket. Each replica picks operations from one or more buckets. If two replicas could pick the same operation at the same time, the controller internally determines a leader that executes this operation.
HA mode does not affect execution of task runs after the pods are created.
| Name | Description | Default value for the OpenShift Pipelines controller |
|---|---|---|
|
| Enable or disable the high availability (HA) mode. By default, the HA mode is enabled. |
|
|
|
In HA mode, the number of buckets used to process controller operations. The maximum value is |
|
|
|
In HA mode, the number of pods created to process controller operations. Set this value to the same or lower number than the |
|
|
| The number of threads (workers) to use when the work queue of the OpenShift Pipelines controller is processed. |
|
|
| The maximum queries per second (QPS) to the cluster master from the REST client. |
|
|
| The maximum burst for a throttle. |
|
The OpenShift Pipelines Operator does not control the number of replicas of the OpenShift Pipelines controller. The replicas setting of the deployment determines the number of replicas. For example, to change the number of replicas to 3, enter the following command:
oc --namespace openshift-pipelines scale deployment openshift-pipelines-controller --replicas=3
$ oc --namespace openshift-pipelines scale deployment openshift-pipelines-controller --replicas=3
The kube-api-qps and kube-api-burst fields are multiplied by 2 in the OpenShift Pipelines controller. For example, if the kube-api-qps and kube-api-burst values are 10, the actual QPS and burst values become 20.
3.3. Configuring the Red Hat OpenShift Pipelines control plane Copy linkLink copied to clipboard!
You can customize the OpenShift Pipelines control plane by editing the configuration fields in the TektonConfig custom resource (CR). The Red Hat OpenShift Pipelines Operator automatically adds the configuration fields with their default values so that you can use the OpenShift Pipelines control plane.
Procedure
- In the Administrator perspective of the web console, navigate to Administration → CustomResourceDefinitions.
-
Use the Search by name box to search for the
tektonconfigs.operator.tekton.devcustom resource definition (CRD). Click TektonConfig to see the CRD details page. - Click the Instances tab.

3.3.1. Modifiable fields with default values Copy linkLink copied to clipboard!
The following list includes all modifiable fields with their default values in the TektonConfig CR:
running-in-environment-with-injected-sidecars(default:true): Set this field tofalseif pipelines run in a cluster that does not use injected sidecars, such as Istio. Setting it tofalsedecreases the time a pipeline takes for a task run to start.NoteFor clusters that use injected sidecars, setting this field to
falsecan lead to an unexpected behavior.-
await-sidecar-readiness(default:true): Set this field tofalseto stop OpenShift Pipelines from waiting forTaskRunsidecar containers to run before it begins to operate. This allows tasks to be run in environments that do not support thedownwardAPIvolume type. -

Metrics options
You can modify the default values of the following metrics fields in the TektonConfig CR:
-
metrics.taskrun.duration-typeandmetrics.pipelinerun.duration-type(default:histogram): Setting these fields determines the duration type for a task or pipeline run. Acceptable value isgaugeorhistogram. -
metrics.taskrun.level(default:task): This field determines the level of the task run metrics. Acceptable value istaskrun,task, ornamespace. -
metrics.pipelinerun.level(default:pipeline): This field determines the level of the pipeline run metrics. Acceptable value ispipelinerun,pipeline, ornamespace.
3.3.2. Optional configuration fields Copy linkLink copied to clipboard!
The following fields do not have a default value, and are considered only if you configure them. By default, the Operator does not add and configure these fields in the TektonConfig custom resource (CR).
-
default-timeout-minutes: This field sets the default timeout for theTaskRunandPipelineRunresources, if none is specified when creating them. If a task run or pipeline run takes more time than the set number of minutes for its execution, then the task run or pipeline run is timed out and cancelled. For example,default-timeout-minutes: 60sets 60 minutes as default. -
default-managed-by-label-value: This field contains the default value given to theapp.kubernetes.io/managed-bylabel that is applied to allTaskRunpods, if none is specified. For example,default-managed-by-label-value: tekton-pipelines. -
default-pod-template: This field sets the defaultTaskRunandPipelineRunpod templates, if none is specified. -
default-cloud-events-sink: This field sets the defaultCloudEventssink that is used for theTaskRunandPipelineRunresources, if none is specified. -
default-task-run-workspace-binding: This field contains the default workspace configuration for the workspaces that aTaskresource declares, but aTaskRunresource does not explicitly declare. -
default-affinity-assistant-pod-template: This field sets the defaultPipelineRunpod template that is used for affinity assistant pods, if none is specified. -
default-max-matrix-combinations-count: This field contains the default maximum number of combinations generated from a matrix, if none is specified.
3.4. Changing the default service account for OpenShift Pipelines Copy linkLink copied to clipboard!
You can change the default service account for OpenShift Pipelines by editing the default-service-account field in the .spec.pipeline and .spec.trigger specifications. The default service account name is pipeline.
Example
3.5. Setting labels and annotations for the OpenShift Pipelines installation namespace Copy linkLink copied to clipboard!
You can set labels and annotations for the openshift-pipelines namespace in which the operator installs OpenShift Pipelines.
Changing the name of the openshift-pipelines namespace is not supported.
Specify the labels and annotations by adding them to the spec.targetNamespaceMetadata specification in the TektonConfig custom resource (CR).
Example of setting labels and annotations for the openshift-pipelines namespace
3.6. Setting the resync period for the pipelines controller Copy linkLink copied to clipboard!
You can configure the resync period for the pipelines controller. Once every resync period, the controller reconciles all pipeline runs and task runs, regardless of events.
The default resync period is 10 hours. If you have a large number of pipeline runs and task runs, a full reconciliation every 10 hours might consume too many resources. In this case, you can configure a longer resync period.
Prerequisites
-
You are logged in to your OpenShift Container Platform cluster with
cluster-adminprivileges.
Procedure
In the
TektonConfigcustom resource, configure the resync period for the pipelines controller, as shown in the following example.Example

- This example sets the resync period to 24 hours.
3.7. Disabling the service monitor Copy linkLink copied to clipboard!
You can disable the service monitor, which is part of OpenShift Pipelines, to expose the telemetry data. To disable the service monitor, set the enableMetrics parameter to false in the .spec.pipeline specification of the TektonConfig custom resource (CR):
Example
3.8. Configuring pipeline resolvers Copy linkLink copied to clipboard!
You can configure pipeline resolvers in the TektonConfig custom resource (CR). You can enable or disable these pipeline resolvers:
-
enable-bundles-resolver -
enable-cluster-resolver -
enable-git-resolver -
enable-hub-resolver
Example
You can also provide resolver specific configurations in the TektonConfig CR. For example, define the following fields in the map[string]string format to set configurations for each pipeline resolver:
Example
3.9. Disabling resolver tasks and pipeline templates Copy linkLink copied to clipboard!
By default, the TektonAddon custom resource (CR) installs resolverTasks and pipelineTemplates resources along with OpenShift Pipelines on the cluster.
You can disable the installation of the resolver tasks and pipeline templates by setting the parameter value to false in the .spec.addon specification.
Procedure

3.10. Disabling the integration of Tekton Hub Copy linkLink copied to clipboard!
You can disable the integration of Tekton Hub in the web console Developer perspective by setting the enable-devconsole-integration parameter to false in the TektonConfig custom resource (CR).
Example of disabling Tekton Hub
3.11. Disabling the automatic creation of RBAC resources Copy linkLink copied to clipboard!
The default installation of the Red Hat OpenShift Pipelines Operator creates multiple role-based access control (RBAC) resources for all namespaces in the cluster, except the namespaces matching the ^(openshift|kube)-* regular expression pattern. Among these RBAC resources, the pipelines-scc-rolebinding security context constraint (SCC) role binding resource is a potential security issue, because the associated pipelines-scc SCC has the RunAsAny privilege.
To disable the automatic creation of cluster-wide RBAC resources after the Red Hat OpenShift Pipelines Operator is installed, cluster administrators can set the createRbacResource parameter to false in the cluster-level TektonConfig custom resource (CR).
Procedure
Edit the
TektonConfigCR by running the following command:oc edit TektonConfig config
$ oc edit TektonConfig configCopy to Clipboard Copied! Toggle word wrap Toggle overflow -
In the
TektonConfigCR, set thecreateRbacResourceparam value tofalse:
Example TektonConfig CR
3.12. Disabling inline specification of pipelines and tasks Copy linkLink copied to clipboard!
By default, OpenShift Pipelines supports inline specification of pipelines and tasks in the following cases:
You can create a
PipelineCR that includes one or more task specifications, as in the following example:Example of an inline specification in a
PipelineCRCopy to Clipboard Copied! Toggle word wrap Toggle overflow You can create a
PipelineRuncustom resource (CR) that includes a pipeline specification, as in the following example:Example of an inline specification in a

3.13. Automatic pruning of task runs and pipeline runs Copy linkLink copied to clipboard!
Stale TaskRun and PipelineRun objects and their executed instances occupy physical resources that can be used for active runs. For optimal utilization of these resources, Red Hat OpenShift Pipelines provides a pruner component that automatically removes unused objects and their instances in various namespaces.
You can configure the pruner for your entire installation by using the TektonConfig custom resource and modify configuration for a namespace by using namespace annotations. However, you cannot selectively auto-prune an individual task run or pipeline run in a namespace.
3.13.1. Configuring the pruner Copy linkLink copied to clipboard!
You can use the TektonConfig custom resource to configure periodic pruning of resources associated with pipeline runs and task runs.
The following example corresponds to the default configuration:
Example of the pruner configuration
| Parameter | Description |
|---|---|
|
| The Cron schedule for running the pruner process. The default schedule runs the process at 08:00 every day. For more information about the Cron schedule syntax, see Cron schedule syntax in the Kubernetes documentation. |
|
|
The resource types to which the pruner applies. The available resource types are |
|
| The number of most recent resources of every type to keep. |
|
|
If set to
If set to |
|
|
The maximum time for which to keep resources, in minutes. For example, to retain resources which were created not more than five days ago, set |
|
| This parameter is optional. If the pruner job is not started at the scheduled time for any reason, this setting configures the maximum time, in seconds, in which the job can still be started. If the job is not started within the specified time, OpenShift Pipelines considers this job failed and starts the pruner at the next scheduled time. If you do not specify this parameter and the pruner job does not start at the scheduled time, OpenShift Pipelines attempts to start the job at any later time possible. |
The keep and keep-since parameters are mutually exclusive. Use only one of them in your configuration.
3.13.2. Annotations for automatically pruning task runs and pipeline runs Copy linkLink copied to clipboard!
To modify the configuration for automatic pruning of task runs and pipeline runs in a namespace, you can set annotations in the namespace.
The following namespace annotations have the same meanings as the corresponding keys in the TektonConfig custom resource:
-
operator.tekton.dev/prune.schedule -
operator.tekton.dev/prune.resources -
operator.tekton.dev/prune.keep -
operator.tekton.dev/prune.prune-per-resource -
operator.tekton.dev/prune.keep-since
The operator.tekton.dev/prune.resources annotation accepts a comma-separated list. To prune both task runs and pipeline runs, set this annotation to "taskrun, pipelinerun".
The following additional namespace annotations are available:
-
operator.tekton.dev/prune.skip: When set totrue, the namespace for which the annotation is configured is not pruned. -
operator.tekton.dev/prune.strategy: Set the value of this annotation to eitherkeeporkeep-since.
For example, the following annotations retain all task runs and pipeline runs created in the last five days and delete the older resources:
Example of auto-pruning annotations
3.14. Setting additional options for webhooks Copy linkLink copied to clipboard!
Optionally, you can set the failurePolicy, timeoutSeconds, or sideEffects options for the webhooks created by several controllers in OpenShift Pipelines. For more information about these options, see the Kubernetes documentation.
