Red Hat OpenShift Pipelines is a cloud-native CI/CD experience based on the Tekton project which provides:

  • Standard Kubernetes-native pipeline definitions (CRDs).

  • Serverless pipelines with no CI server management overhead.

  • Extensibility to build images using any Kubernetes tool, such as S2I, Buildah, JIB, and Kaniko.

  • Portability across any Kubernetes distribution.

  • Powerful CLI for interacting with pipelines.

  • Integrated user experience with the Developer perspective of the OpenShift Container Platform web console.

For an overview of Red Hat OpenShift Pipelines, see Understanding OpenShift Pipelines.

Making open source more inclusive

Red Hat is committed to replacing problematic language in our code, documentation, and web properties. We are beginning with these four terms: master, slave, blacklist, and whitelist. Because of the enormity of this endeavor, these changes will be implemented gradually over several upcoming releases. For more details, see Red Hat CTO Chris Wright’s message.

New features

In addition to the fixes and stability improvements, the following sections highlight what is new in Red Hat OpenShift Pipelines 1.4.

  • The custom tasks have the following enhancements:

    • Pipeline results can now refer to results produced by custom tasks.

    • Custom tasks can now use workspaces, service accounts, and pod templates to build more complex custom tasks.

  • The finally task has the following enhancements:

    • The when expressions are supported in finally tasks, which provides efficient guarded execution and improved reusability of tasks.

    • A finally task can be configured to consume the results of any task within the same pipeline.

      Support for when expressions and finally tasks are unavailable in the OpenShift Container Platform 4.7 web console.

  • Support for multiple secrets of the type dockercfg or dockerconfigjson is added for authentication at runtime.

  • Functionality to support sparse-checkout with the git-clone task is added. This enables you to clone only a subset of the repository as your local copy, and helps you to restrict the size of the cloned repositories.

  • You can create pipeline runs in a pending state without actually starting them. In clusters that are under heavy load, this allows Operators to have control over the start time of the pipeline runs.

  • Ensure that you set the SYSTEM_NAMESPACE environment variable manually for the controller; this was previously set by default.

  • A non-root user is now added to the build-base image of pipelines so that git-init can clone repositories as a non-root user.

  • Support to validate dependencies between resolved resources before a pipeline run starts is added. All result variables in the pipeline must be valid, and optional workspaces from a pipeline can only be passed to tasks expecting it for the pipeline to start running.

  • The controller and webhook runs as a non-root group, and their superfluous capabilities have been removed to make them more secure.

  • You can use the tkn pr logs command to see the log streams for retried task runs.

  • You can use the --clustertask option in the tkn tr delete command to delete all the task runs associated with a particular cluster task.

  • Support for using Knative service with the EventListener resource is added by introducing a new customResource field.

  • An error message is displayed when an event payload does not use the JSON format.

  • The source control interceptors such as GitLab, BitBucket, and GitHub, now use the new InterceptorRequest or InterceptorResponse type interface.

  • A new CEL function marshalJSON is implemented so that you can encode a JSON object or an array to a string.

  • An HTTP handler for serving the CEL and the source control core interceptors is added. It packages four core interceptors into a single HTTP server that is deployed in the tekton-pipelines namespace. The EventListener object forwards events over the HTTP server to the interceptor. Each interceptor is available at a different path. For example, the CEL interceptor is available on the /cel path.

  • The pipelines-scc Security Context Constraint (SCC) is used with the default pipeline service account for pipelines. This new service account is similar to anyuid, but with a minor difference as defined in the YAML for SCC of OpenShift Container Platform 4.7:

      type: MustRunAs

Deprecated features

  • The build-gcs sub-type in the pipeline resource storage, and the gcs-fetcher image, are not supported.

  • In the taskRun field of cluster tasks, the label tekton.dev/task is removed.

  • For webhooks, the value v1beta1 corresponding to the field admissionReviewVersions is removed.

  • The creds-init helper image for building and deploying is removed.

  • In the triggers spec and binding, the deprecated field template.name is removed in favor of template.ref. You should update all eventListener definitions to use the ref field.

    Upgrade from Pipelines 1.3.x and earlier versions to Pipelines 1.4.0 breaks event listeners because of the unavailability of the template.name field. For such cases, use Pipelines 1.4.1 to avail the restored template.name field.

  • For EventListener custom resources/objects, the fields PodTemplate and ServiceType are deprecated in favor of Resource.

  • The deprecated spec style embedded bindings is removed.

  • The spec field is removed from the triggerSpecBinding.

  • The event ID representation is changed from a five-character random string to a UUID.

Known issues

  • In the Developer perspective, the pipeline metrics and triggers features are available only on OpenShift Container Platform 4.7.6 or later versions.

  • On IBM Power Systems, IBM Z, and LinuxONE, the tkn hub command is not supported.

  • When you run Maven and Jib Maven cluster tasks on an IBM Power Systems (ppc64le), IBM Z, and LinuxONE (s390x) clusters, set the MAVEN_IMAGE parameter value to maven:3.6.3-adoptopenjdk-11.

  • Triggers throw error resulting from bad handling of the JSON format, if you have the following configuration in the trigger binding:

      - name: github_json
        value: $(body)

    To resolve the issue:

    • If you are using triggers v0.11.0 and above, use the marshalJSON CEL function, which takes a JSON object or array and returns the JSON encoding of that object or array as a string.

    • If you are using older triggers version, add the following annotation in the trigger template:

        triggers.tekton.dev/old-escape-quotes: "true"
  • When upgrading from Pipelines 1.3.x to 1.4.x, you must recreate the routes.

Fixed issues

  • Previously, the tekton.dev/task label was removed from the task runs of cluster tasks, and the tekton.dev/clusterTask label was introduced. The problems resulting from that change is resolved by fixing the clustertask describe and delete commands. In addition, the lastrun function for tasks is modified, to fix the issue of the tekton.dev/task label being applied to the task runs of both tasks and cluster tasks in older versions of pipelines.

  • When doing an interactive tkn pipeline start pipelinename, a PipelineResource is created interactively. The tkn p start command prints the resource status if the resource status is not nil.

  • Previously, the tekton.dev/task=name label was removed from the task runs created from cluster tasks. This fix modifies the tkn clustertask start command with the --last flag to check for the tekton.dev/task=name label in the created task runs.

  • When a task uses an inline task specification, the corresponding task run now gets embedded in the pipeline when you run the tkn pipeline describe command, and the task name is returned as embedded.

  • The tkn version command is fixed to display the version of the installed Tekton CLI tool, without a configured kubeConfiguration namespace or access to a cluster.

  • If an argument is unexpected or more than one arguments are used, the tkn completion command gives an error.

  • Previously, pipeline runs with the finally tasks nested in a pipeline specification would lose those finally tasks, when converted to the v1alpha1 version and restored back to the v1beta1 version. This error occurring during conversion is fixed to avoid potential data loss. Pipeline runs with the finally tasks nested in a pipeline specification is now serialized and stored on the alpha version, only to be deserialized later.

  • Previously, there was an error in the pod generation when a service account had the secrets field as {}. The task runs failed with CouldntGetTask because the GET request with an empty secret name returned an error, indicating that the resource name may not be empty. This issue is fixed by avoiding an empty secret name in the kubeclient GET request.

  • Pipelines with the v1beta1 API versions can now be requested along with the v1alpha1 version, without losing the finally tasks. Applying the returned v1alpha1 version will store the resource as v1beta1, with the finally section restored to its original state.

  • Previously, an unset selfLink field in the controller caused an error in the Kubernetes v1.20 clusters. As a temporary fix, the CloudEvent source field is set to a value that matches the current source URI, without the value of the auto-populated selfLink field.

  • Previously, a secret name with dots such as gcr.io led to a task run creation failure. This happened because of the secret name being used internally as part of a volume mount name. The volume mount name conforms to the RFC1123 DNS label and disallows dots as part of the name. This issue is fixed by replacing the dot with a dash that results in a readable name.

  • Context variables are now validated in the finally tasks.

  • Previously, when the task run reconciler was passed a task run that did not have a previous status update containing the name of the pod it created, the task run reconciler listed the pods associated with the task run. The task run reconciler used the labels of the task run, which were propagated to the pod, to find the pod. Changing these labels while the task run was running, caused the code to not find the existing pod. As a result, duplicate pods were created. This issue is fixed by changing the task run reconciler to only use the tekton.dev/taskRun Tekton-controlled label when finding the pod.

  • Previously, when a pipeline accepted an optional workspace and passed it to a pipeline task, the pipeline run reconciler stopped with an error if the workspace was not provided, even if a missing workspace binding is a valid state for an optional workspace. This issue is fixed by ensuring that the pipeline run reconciler does not fail to create a task run, even if an optional workspace is not provided.

  • The sorted order of step statuses matches the order of step containers.

  • Previously, the task run status was set to unknown when a pod encountered the CreateContainerConfigError reason, which meant that the task and the pipeline ran until the pod timed out. This issue is fixed by setting the task run status to false, so that the task is set as failed when the pod encounters the CreateContainerConfigError reason.

  • Previously, pipeline results were resolved on the first reconciliation, after a pipeline run was completed. This could fail the resolution resulting in the Succeeded condition of the pipeline run being overwritten. As a result, the final status information was lost, potentially confusing any services watching the pipeline run conditions. This issue is fixed by moving the resolution of pipeline results to the end of a reconciliation, when the pipeline run is put into a Succeeded or True condition.

  • Execution status variable is now validated. This avoids validating task results while validating context variables to access execution status.

  • Previously, a pipeline result that contained an invalid variable would be added to the pipeline run with the literal expression of the variable intact. Therefore, it was difficult to assess whether the results were populated correctly. This issue is fixed by filtering out the pipeline run results that reference failed task runs. Now, a pipeline result that contains an invalid variable will not be emitted by the pipeline run at all.

  • The tkn eventlistener describe command is fixed to avoid crashing without a template. It also displays the details about trigger references.

  • Upgrades from Pipelines 1.3.x and earlier versions to Pipelines 1.4.0 breaks event listeners because of the unavailability of template.name. In Pipelines 1.4.1, the template.name has been restored to avoid breaking event listeners in triggers.

  • In Pipelines 1.4.1, the ConsoleQuickStart custom resource has been updated to align with OpenShift Container Platform 4.7 capabilities and behavior.

Release notes for Red Hat OpenShift Pipelines Technology Preview 1.3

New features

Red Hat OpenShift Pipelines Technology Preview (TP) 1.3 is now available on OpenShift Container Platform 4.7. Red Hat OpenShift Pipelines TP 1.3 is updated to support:

  • Tekton Pipelines 0.19.0

  • Tekton tkn CLI 0.15.0

  • Tekton Triggers 0.10.2

  • cluster tasks based on Tekton Catalog 0.19.0

  • IBM Power Systems on OpenShift Container Platform 4.7

  • IBM Z and LinuxONE on OpenShift Container Platform 4.7

In addition to the fixes and stability improvements, the following sections highlight what is new in Red Hat OpenShift Pipelines 1.3.


  • Tasks that build images, such as S2I and Buildah tasks, now emit a URL of the image built that includes the image SHA.

  • Conditions in pipeline tasks that reference custom tasks are disallowed because the Condition custom resource definition (CRD) has been deprecated.

  • Variable expansion is now added in the Task CRD for the following fields: spec.steps[].imagePullPolicy and spec.sidecar[].imagePullPolicy.

  • You can disable the built-in credential mechanism in Tekton by setting the disable-creds-init feature-flag to true.

  • Resolved when expressions are now listed in the Skipped Tasks and the Task Runs sections in the Status field of the PipelineRun configuration.

  • The git init command can now clone recursive submodules.

  • A Task CR author can now specify a timeout for a step in the Task spec.

  • You can now base the entry point image on the distroless/static:nonroot image and give it a mode to copy itself to the destination, without relying on the cp command being present in the base image.

  • You can now use the configuration flag require-git-ssh-secret-known-hosts to disallow omitting known hosts in the Git SSH secret. When the flag value is set to true, you must include the known_host field in the Git SSH secret. The default value for the flag is false.

  • The concept of optional workspaces is now introduced. A task or pipeline might declare a workspace optional and conditionally change their behavior based on its presence. A task run or pipeline run might also omit that workspace, thereby modifying the task or pipeline behavior. The default task run workspaces are not added in place of an omitted optional workspace.

  • Credentials initialization in Tekton now detects an SSH credential that is used with a non-SSH URL, and vice versa in Git pipeline resources, and logs a warning in the step containers.

  • The task run controller emits a warning event if the affinity specified by the pod template is overwritten by the affinity assistant.

  • The task run reconciler now records metrics for cloud events that are emitted once a task run is completed. This includes retries.

Pipelines CLI

  • Support for --no-headers flag is now added to the following commands: tkn condition list,tkn triggerbinding list,tkn eventlistener list,tkn clustertask list, tkn clustertriggerbinding list.

  • When used together, the --last or --use options override the --prefix-name and --timeout options.

  • The tkn eventlistener logs command is now added to view the EventListener logs.

  • The tekton hub commands are now integrated into the tkn CLI.

  • The --nocolour option is now changed to --no-color.

  • The --all-namespaces flag is added to the following commands: tkn triggertemplate list, tkn condition list, tkn triggerbinding list, tkn eventlistener list.


  • You can now specify your resource information in the EventListener template.

  • It is now mandatory for EventListener service accounts to have the list and watch verbs, in addition to the get verb for all the triggers resources. This enables you to use Listers to fetch data from EventListener, Trigger, TriggerBinding, TriggerTemplate, and ClusterTriggerBinding resources. You can use this feature to create a Sink object rather than specifying multiple informers, and directly make calls to the API server.

  • A new Interceptor interface is added to support immutable input event bodies. Interceptors can now add data or fields to a new extensions field, and cannot modify the input bodies making them immutable. The CEL interceptor uses this new Interceptor interface.

  • A namespaceSelector field is added to the EventListener resource. Use it to specify the namespaces from where the EventListener resource can fetch the Trigger object for processing events. To use the namespaceSelector field, the service account for the EventListener resource must have a cluster role.

  • The triggers EventListener resource now supports end-to-end secure connection to the eventlistener pod.

  • The escaping parameters behavior in the TriggerTemplates resource by replacing " with \" is now removed.

  • A new resources field, supporting Kubernetes resources, is introduced as part of the EventListener spec.

  • A new functionality for the CEL interceptor, with support for upper and lower-casing of ASCII strings, is added.

  • You can embed TriggerBinding resources by using the name and value fields in a trigger, or an event listener.

  • The PodSecurityPolicy configuration is updated to run in restricted environments. It ensures that containers must run as non-root. In addition, the role-based access control for using the pod security policy is moved from cluster-scoped to namespace-scoped. This ensures that the triggers cannot use other pod security policies that are unrelated to a namespace.

  • Support for embedded trigger templates is now added. You can either use the name field to refer to an embedded template or embed the template inside the spec field.

Deprecated features

  • Pipeline templates that use PipelineResources CRDs are now deprecated and will be removed in a future release.

  • The template.name field is deprecated in favor of the template.ref field and will be removed in a future release.

  • The -c shorthand for the --check command has been removed. In addition, global tkn flags are added to the version command.

Known issues

  • CEL overlays add fields to a new top-level extensions function, instead of modifying the incoming event body. TriggerBinding resources can access values within this new extensions function using the $(extensions.<key>) syntax. Update your binding to use the $(extensions.<key>) syntax instead of the $(body.<overlay-key>) syntax.

  • The escaping parameters behavior by replacing " with \" is now removed. If you need to retain the old escaping parameters behavior add the tekton.dev/old-escape-quotes: true" annotation to your TriggerTemplate specification.

  • You can embed TriggerBinding resources by using the name and value fields inside a trigger or an event listener. However, you cannot specify both name and ref fields for a single binding. Use the ref field to refer to a TriggerBinding resource and the name field for embedded bindings.

  • An interceptor cannot attempt to reference a secret outside the namespace of an EventListener resource. You must include secrets in the namespace of the `EventListener`resource.

  • In Triggers 0.9.0 and later, if a body or header based TriggerBinding parameter is missing or malformed in an event payload, the default values are used instead of displaying an error.

  • Tasks and pipelines created with WhenExpression objects using Tekton Pipelines 0.16.x must be reapplied to fix their JSON annotations.

  • When a pipeline accepts an optional workspace and gives it to a task, the pipeline run stalls if the workspace is not provided.

  • To use the Buildah cluster task in a disconnected environment, ensure that the Dockerfile uses an internal image stream as the base image, and then use it in the same manner as any S2I cluster task.

Fixed issues

  • Extensions added by a CEL Interceptor are passed on to webhook interceptors by adding the Extensions field within the event body.

  • The activity timeout for log readers is now configurable using the LogOptions field. However, the default behavior of timeout in 10 seconds is retained.

  • The log command ignores the --follow flag when a task run or pipeline run is complete, and reads available logs instead of live logs.

  • References to the following Tekton resources: EventListener, TriggerBinding, ClusterTriggerBinding, Condition, and TriggerTemplate are now standardized and made consistent across all user-facing messages in tkn commands.

  • Previously, if you started a canceled task run or pipeline run with the --use-taskrun <canceled-task-run-name>, --use-pipelinerun <canceled-pipeline-run-name> or --last flags, the new run would be canceled. This bug is now fixed.

  • The tkn pr desc command is now enhanced to ensure that it does not fail in case of pipeline runs with conditions.

  • When you delete a task run using the tkn tr delete command with the --task option, and a cluster task exists with the same name, the task runs for the cluster task also get deleted. As a workaround, filter the task runs by using the TaskRefKind field.

  • The tkn triggertemplate describe command would display only part of the apiVersion value in the output. For example, only triggers.tekton.dev was displayed instead of triggers.tekton.dev/v1alpha1. This bug is now fixed.

  • The webhook, under certain conditions, would fail to acquire a lease and not function correctly. This bug is now fixed.

  • Pipelines with when expressions created in v0.16.3 can now be run in v0.17.1 and later. After an upgrade, you do not need to reapply pipeline definitions created in previous versions because both the uppercase and lowercase first letters for the annotations are now supported.

  • By default, the leader-election-ha field is now enabled for high availability. When the disable-ha controller flag is set to true, it disables high availability support.

  • Issues with duplicate cloud events are now fixed. Cloud events are now sent only when a condition changes the state, reason, or message.

  • When a service account name is missing from a PipelineRun or TaskRun spec, the controller uses the service account name from the config-defaults config map. If the service account name is also missing in the config-defaults config map, the controller now sets it to default in the spec.

  • Validation for compatibility with the affinity assistant is now supported when the same persistent volume claim is used for multiple workspaces, but with different subpaths.

Release notes for Red Hat OpenShift Pipelines Technology Preview 1.2

New features

Red Hat OpenShift Pipelines Technology Preview (TP) 1.2 is now available on OpenShift Container Platform 4.6. Red Hat OpenShift Pipelines TP 1.2 is updated to support:

  • Tekton Pipelines 0.16.3

  • Tekton tkn CLI 0.13.1

  • Tekton Triggers 0.8.1

  • cluster tasks based on Tekton Catalog 0.16

  • IBM Power Systems on OpenShift Container Platform 4.6

  • IBM Z and LinuxONE on OpenShift Container Platform 4.6

In addition to the fixes and stability improvements, the following sections highlight what is new in Red Hat OpenShift Pipelines 1.2.


  • This release of Red Hat OpenShift Pipelines adds support for a disconnected installation.

    Installations in restricted environments are currently not supported on IBM Power Systems, IBM Z, and LinuxONE.

  • You can now use the when field, instead of conditions resource, to run a task only when certain criteria are met. The key components of WhenExpression resources are Input, Operator, and Values. If all the when expressions evaluate to True, then the task is run. If any of the when expressions evaluate to False, the task is skipped.

  • Step statuses are now updated if a task run is canceled or times out.

  • Support for Git Large File Storage (LFS) is now available to build the base image used by git-init.

  • You can now use the taskSpec field to specify metadata, such as labels and annotations, when a task is embedded in a pipeline.

  • Cloud events are now supported by pipeline runs. Retries with backoff are now enabled for cloud events sent by the cloud event pipeline resource.

  • You can now set a default Workspace configuration for any workspace that a Task resource declares, but that a TaskRun resource does not explicitly provide.

  • Support is available for namespace variable interpolation for the PipelineRun namespace and TaskRun namespace.

  • Validation for TaskRun objects is now added to check that not more than one persistent volume claim workspace is used when a TaskRun resource is associated with an Affinity Assistant. If more than one persistent volume claim workspace is used, the task run fails with a TaskRunValidationFailed condition. Note that by default, the Affinity Assistant is disabled in Red Hat OpenShift Pipelines, so you will need to enable the assistant to use it.

Pipelines CLI

  • The tkn task describe, tkn taskrun describe, tkn clustertask describe, tkn pipeline describe, and tkn pipelinerun describe commands now:

    • Automatically select the Task, TaskRun, ClusterTask, Pipeline and PipelineRun resource, respectively, if only one of them is present.

    • Display the results of the Task, TaskRun, ClusterTask, Pipeline and PipelineRun resource in their outputs, respectively.

    • Display workspaces declared in the Task, TaskRun, ClusterTask, Pipeline and PipelineRun resource in their outputs, respectively.

  • You can now use the --prefix-name option with the tkn clustertask start command to specify a prefix for the name of a task run.

  • Interactive mode support has now been provided to the tkn clustertask start command.

  • You can now specify PodTemplate properties supported by pipelines using local or remote file definitions for TaskRun and PipelineRun objects.

  • You can now use the --use-params-defaults option with the tkn clustertask start command to use the default values set in the ClusterTask configuration and create the task run.

  • The --use-param-defaults flag for the tkn pipeline start command now prompts the interactive mode if the default values have not been specified for some of the parameters.


  • The Common Expression Language (CEL) function named parseYAML has been added to parse a YAML string into a map of strings.

  • Error messages for parsing CEL expressions have been improved to make them more granular while evaluating expressions and when parsing the hook body for creating the evaluation environment.

  • Support is now available for marshaling boolean values and maps if they are used as the values of expressions in a CEL overlay mechanism.

  • The following fields have been added to the EventListener object:

    • The replicas field enables the event listener to run more than one pod by specifying the number of replicas in the YAML file.

    • The NodeSelector field enables the EventListener object to schedule the event listener pod to a specific node.

  • Webhook interceptors can now parse the EventListener-Request-URL header to extract parameters from the original request URL being handled by the event listener.

  • Annotations from the event listener can now be propagated to the deployment, services, and other pods. Note that custom annotations on services or deployment are overwritten, and hence, must be added to the event listener annotations so that they are propagated.

  • Proper validation for replicas in the EventListener specification is now available for cases when a user specifies the spec.replicas values as negative or zero.

  • You can now specify the TriggerCRD object inside the EventListener spec as a reference using the TriggerRef field to create the TriggerCRD object separately and then bind it inside the EventListener spec.

  • Validation and defaults for the TriggerCRD object are now available.

Deprecated features

  • $(params) parameters are now removed from the triggertemplate resource and replaced by $(tt.params) to avoid confusion between the resourcetemplate and triggertemplate resource parameters.

  • The ServiceAccount reference of the optional EventListenerTrigger-based authentication level has changed from an object reference to a ServiceAccountName string. This ensures that the ServiceAccount reference is in the same namespace as the EventListenerTrigger object.

  • The Conditions custom resource definition (CRD) is now deprecated; use the WhenExpressions CRD instead.

  • The PipelineRun.Spec.ServiceAccountNames object is being deprecated and replaced by the PipelineRun.Spec.TaskRunSpec[].ServiceAccountName object.

Known issues

  • This release of Red Hat OpenShift Pipelines adds support for a disconnected installation. However, some images used by the cluster tasks must be mirrored for them to work in disconnected clusters.

  • Pipelines in the openshift namespace are not deleted after you uninstall the Red Hat OpenShift Pipelines Operator. Use the oc delete pipelines -n openshift --all command to delete the pipelines.

  • Uninstalling the Red Hat OpenShift Pipelines Operator does not remove the event listeners.

    As a workaround, to remove the EventListener and Pod CRDs:

    1. Edit the EventListener object with the foregroundDeletion finalizers:

      $ oc patch el/<eventlistener_name> -p '{"metadata":{"finalizers":["foregroundDeletion"]}}' --type=merge

      For example:

      $ oc patch el/github-listener-interceptor -p '{"metadata":{"finalizers":["foregroundDeletion"]}}' --type=merge
    2. Delete the EventListener CRD:

      $ oc patch crd/eventlisteners.triggers.tekton.dev -p '{"metadata":{"finalizers":[]}}' --type=merge
  • When you run a multi-arch container image task without command specification on an IBM Power Systems (ppc64le) or IBM Z (s390x) cluster, the TaskRun resource fails with the following error:

    Error executing command: fork/exec /bin/bash: exec format error

    As a workaround, use an architecture specific container image or specify the sha256 digest to point to the correct architecture. To get the sha256 digest enter:

    $ skopeo inspect --raw <image_name>| jq '.manifests[] | select(.platform.architecture == "<architecture>") | .digest'

Fixed issues

  • A simple syntax validation to check the CEL filter, overlays in the Webhook validator, and the expressions in the interceptor has now been added.

  • Triggers no longer overwrite annotations set on the underlying deployment and service objects.

  • Previously, an event listener would stop accepting events. This fix adds an idle timeout of 120 seconds for the EventListener sink to resolve this issue.

  • Previously, canceling a pipeline run with a Failed(Canceled) state gave a success message. This has been fixed to display an error instead.

  • The tkn eventlistener list command now provides the status of the listed event listeners, thus enabling you to easily identify the available ones.

  • Consistent error messages are now displayed for the triggers list and triggers describe commands when triggers are not installed or when a resource cannot be found.

  • Previously, a large number of idle connections would build up during cloud event delivery. The DisableKeepAlives: true parameter was added to the cloudeventclient config to fix this issue. Thus, a new connection is set up for every cloud event.

  • Previously, the creds-init code would write empty files to the disk even if credentials of a given type were not provided. This fix modifies the creds-init code to write files for only those credentials that have actually been mounted from correctly annotated secrets.

Release notes for Red Hat OpenShift Pipelines Technology Preview 1.1

New features

Red Hat OpenShift Pipelines Technology Preview (TP) 1.1 is now available on OpenShift Container Platform 4.5. Red Hat OpenShift Pipelines TP 1.1 is updated to support:

  • Tekton Pipelines 0.14.3

  • Tekton tkn CLI 0.11.0

  • Tekton Triggers 0.6.1

  • cluster tasks based on Tekton Catalog 0.14

In addition to the fixes and stability improvements, the following sections highlight what is new in Red Hat OpenShift Pipelines 1.1.


  • Workspaces can now be used instead of pipeline resources. It is recommended that you use workspaces in OpenShift Pipelines, as pipeline resources are difficult to debug, limited in scope, and make tasks less reusable. For more details on workspaces, see the Understanding OpenShift Pipelines section.

  • Workspace support for volume claim templates has been added:

    • The volume claim template for a pipeline run and task run can now be added as a volume source for workspaces. The tekton-controller then creates a persistent volume claim (PVC) using the template that is seen as a PVC for all task runs in the pipeline. Thus you do not need to define the PVC configuration every time it binds a workspace that spans multiple tasks.

    • Support to find the name of the PVC when a volume claim template is used as a volume source is now available using variable substitution.

  • Support for improving audits:

    • The PipelineRun.Status field now contains the status of every task run in the pipeline and the pipeline specification used to instantiate a pipeline run to monitor the progress of the pipeline run.

    • Pipeline results have been added to the pipeline specification and PipelineRun status.

    • The TaskRun.Status field now contains the exact task specification used to instantiate the TaskRun resource.

  • Support to apply the default parameter to conditions.

  • A task run created by referencing a cluster task now adds the tekton.dev/clusterTask label instead of the tekton.dev/task label.

  • The kube config writer now adds the ClientKeyData and the ClientCertificateData configurations in the resource structure to enable replacement of the pipeline resource type cluster with the kubeconfig-creator task.

  • The names of the feature-flags and the config-defaults config maps are now customizable.

  • Support for the host network in the pod template used by the task run is now available.

  • An Affinity Assistant is now available to support node affinity in task runs that share workspace volume. By default, this is disabled on OpenShift Pipelines.

  • The pod template has been updated to specify imagePullSecrets to identify secrets that the container runtime should use to authorize container image pulls when starting a pod.

  • Support for emitting warning events from the task run controller if the controller fails to update the task run.

  • Standard or recommended k8s labels have been added to all resources to identify resources belonging to an application or component.

  • The Entrypoint process is now notified for signals and these signals are then propagated using a dedicated PID Group of the Entrypoint process.

  • Support for emitting Kubernetes events:

    • The controller now emits events for additional task run lifecycle events - taskrun started and taskrun running.

    • The pipeline run controller now emits an event every time a pipeline starts.

  • In addition to the default Kubernetes events, support for cloud events for task runs is now available. The controller can be configured to send any task run events, such as create, started, and failed, as cloud events.

  • Support for using the $context.<task|taskRun|pipeline|pipelineRun>.name variable to reference the appropriate name when in pipeline runs and task runs.

  • Validation for pipeline run parameters is now available to ensure that all the parameters required by the pipeline are provided by the pipeline run. This also allows pipeline runs to provide extra parameters in addition to the required parameters.

  • You can now specify tasks within a pipeline that will always execute before the pipeline exits, either after finishing all tasks successfully or after a task in the pipeline failed, using the finally field in the pipeline YAML file.

  • The git-clone cluster task is now available.

Pipelines CLI

  • Support for embedded trigger binding is now available to the tkn evenlistener describe command.

  • A new interceptor for webhooks from Bitbucket has been added.

  • Event listeners now display the Address URL and the Available status as additional fields when listed with the kubectl get command.

  • trigger template params now use the $(tt.params.<paramName>) syntax instead of $(params.<paramName>) to reduce the confusion between trigger template and resource templates params.

  • You can now add tolerations in the EventListener CRD to ensure that event listeners are deployed with the same configuration even if all nodes are tainted due to security or management issues.

  • You can now add a Readiness Probe for event listener Deployment at URL/live.

  • Support for embedding TriggerBinding specifications in event listener triggers is now added.

Deprecated features

The following items are deprecated in this release:

  • The --namespace or -n flags for all cluster-wide commands, including the clustertask and clustertriggerbinding commands, are deprecated. It will be removed in a future release.

  • The name field in triggers.bindings within an event listener has been deprecated in favor of the ref field and will be removed in a future release.

  • Variable interpolation in trigger templates using $(params) has been deprecated in favor of using $(tt.params) to reduce confusion with the pipeline variable interpolation syntax. The $(params.<paramName>) syntax will be removed in a future release.

  • The tekton.dev/task label is deprecated on cluster tasks.

  • The TaskRun.Status.ResourceResults.ResourceRef field is deprecated and will be removed.

  • The tkn pipeline create, tkn task create, and tkn resource create -f subcommands have been removed.

  • Namespace validation has been removed from tkn commands.

  • The default timeout of 1h and the -t flag for the tkn ct start command have been removed.

  • The s2i cluster task has been deprecated.

Known issues

  • Conditions do not support workspaces.

  • The --workspace option and the interactive mode is not supported for the tkn clustertask start command.

  • Support of backward compatibility for $(params.<paramName>) syntax forces you to use trigger templates with pipeline specific params as the trigger s webhook is unable to differentiate trigger params from pipelines params.

  • Pipeline metrics report incorrect values when you run a promQL query for tekton_taskrun_count and tekton_taskrun_duration_seconds_count.

  • pipeline runs and task runs continue to be in the Running and Running(Pending) states respectively even when a non existing PVC name is given to a workspace.

Fixed issues

  • Previously, the tkn task delete <name> --trs command would delete both the task and cluster task if the name of the task and cluster task were the same. With this fix, the command deletes only the task runs that are created by the task <name>.

  • Previously the tkn pr delete -p <name> --keep 2 command would disregard the -p flag when used with the --keep flag and would delete all the pipeline runs except the latest two. With this fix, the command deletes only the pipeline runs that are created by the pipeline <name>, except for the latest two.

  • The tkn triggertemplate describe output now displays resource templates in a table format instead of YAML format.

  • Previously the buildah cluster task failed when a new user was added to a container. With this fix, the issue has been resolved.

Release notes for Red Hat OpenShift Pipelines Technology Preview 1.0

New features

Red Hat OpenShift Pipelines Technology Preview (TP) 1.0 is now available on OpenShift Container Platform 4.4. Red Hat OpenShift Pipelines TP 1.0 is updated to support:

  • Tekton Pipelines 0.11.3

  • Tekton tkn CLI 0.9.0

  • Tekton Triggers 0.4.0

  • cluster tasks based on Tekton Catalog 0.11

In addition to the fixes and stability improvements, the following sections highlight what is new in Red Hat OpenShift Pipelines 1.0.


  • Support for v1beta1 API Version.

  • Support for an improved limit range. Previously, limit range was specified exclusively for the task run and the pipeline run. Now there is no need to explicitly specify the limit range. The minimum limit range across the namespace is used.

  • Support for sharing data between tasks using task results and task params.

  • Pipelines can now be configured to not overwrite the HOME environment variable and the working directory of steps.

  • Similar to task steps, sidecars now support script mode.

  • You can now specify a different scheduler name in task run podTemplate resource.

  • Support for variable substitution using Star Array Notation.

  • Tekton controller can now be configured to monitor an individual namespace.

  • A new description field is now added to the specification of pipelines, tasks, cluster tasks, resources, and conditions.

  • Addition of proxy parameters to Git pipeline resources.

Pipelines CLI

  • The describe subcommand is now added for the following tkn resources: EventListener, Condition, TriggerTemplate, ClusterTask, and TriggerSBinding.

  • Support added for v1beta1 to the following resources along with backward compatibility for v1alpha1: ClusterTask, Task, Pipeline, PipelineRun, and TaskRun.

  • The following commands can now list output from all namespaces using the --all-namespaces flag option: tkn task list, tkn pipeline list, tkn taskrun list, tkn pipelinerun list

    The output of these commands is also enhanced to display information without headers using the --no-headers flag option.

  • You can now start a pipeline using default parameter values by specifying --use-param-defaults flag in the tkn pipelines start command.

  • Support for workspace is now added to tkn pipeline start and tkn task start commands.

  • A new clustertriggerbinding command is now added with the following subcommands: describe, delete, and list.

  • You can now directly start a pipeline run using a local or remote yaml file.

  • The describe subcommand now displays an enhanced and detailed output. With the addition of new fields, such as description, timeout, param description, and sidecar status, the command output now provides more detailed information about a specific tkn resource.

  • The tkn task log command now displays logs directly if only one task is present in the namespace.


  • Triggers can now create both v1alpha1 and v1beta1 pipeline resources.

  • Support for new Common Expression Language (CEL) interceptor function - compareSecret. This function securely compares strings to secrets in CEL expressions.

  • Support for authentication and authorization at the event listener trigger level.

Deprecated features

The following items are deprecated in this release:

  • The environment variable $HOME, and variable workingDir in the Steps specification are deprecated and might be changed in a future release. Currently in a Step container, the HOME and workingDir variables are overwritten to /tekton/home and /workspace variables, respectively.

    In a later release, these two fields will not be modified, and will be set to values defined in the container image and the Task YAML. For this release, use the disable-home-env-overwrite and disable-working-directory-overwrite flags to disable overwriting of the HOME and workingDir variables.

  • The following commands are deprecated and might be removed in the future release: tkn pipeline create, tkn task create.

  • The -f flag with the tkn resource create command is now deprecated. It might be removed in the future release.

  • The -t flag and the --timeout flag (with seconds format) for the tkn clustertask create command are now deprecated. Only duration timeout format is now supported, for example 1h30s. These deprecated flags might be removed in the future release.

Known issues

  • If you are upgrading from an older version of Red Hat OpenShift Pipelines, you must delete your existing deployments before upgrading to Red Hat OpenShift Pipelines version 1.0. To delete an existing deployment, you must first delete Custom Resources and then uninstall the Red Hat OpenShift Pipelines Operator. For more details, see the uninstalling Red Hat OpenShift Pipelines section.

  • Submitting the same v1alpha1 tasks more than once results in an error. Use the oc replace command instead of oc apply when re-submitting a v1alpha1 task.

  • The buildah cluster task does not work when a new user is added to a container.

    When the Operator is installed, the --storage-driver flag for the buildah cluster task is not specified, therefore the flag is set to its default value. In some cases, this causes the storage driver to be set incorrectly. When a new user is added, the incorrect storage-driver results in the failure of the buildah cluster task with the following error:

    useradd: /etc/passwd.8: lock file already used
    useradd: cannot lock /etc/passwd; try again later.

    As a workaround, manually set the --storage-driver flag value to overlay in the buildah-task.yaml file:

    1. Login to your cluster as a cluster-admin:

      $ oc login -u <login> -p <password> https://openshift.example.com:6443
    2. Use the oc edit command to edit buildah cluster task:

      $ oc edit clustertask buildah

      The current version of the buildah clustertask YAML file opens in the editor set by your EDITOR environment variable.

    3. Under the Steps field, locate the following command field:

       command: ['buildah', 'bud', '--format=$(params.FORMAT)', '--tls-verify=$(params.TLSVERIFY)', '--layers', '-f', '$(params.DOCKERFILE)', '-t', '$(resources.outputs.image.url)', '$(params.CONTEXT)']
    4. Replace the command field with the following:

       command: ['buildah', '--storage-driver=overlay', 'bud', '--format=$(params.FORMAT)', '--tls-verify=$(params.TLSVERIFY)', '--no-cache', '-f', '$(params.DOCKERFILE)', '-t', '$(params.IMAGE)', '$(params.CONTEXT)']
    5. Save the file and exit.

    Alternatively, you can also modify the buildah cluster task YAML file directly on the web console by navigating to PipelinesCluster Tasksbuildah. Select Edit Cluster Task from the Actions menu and replace the command field as shown in the previous procedure.

Fixed issues

  • Previously, the DeploymentConfig task triggered a new deployment build even when an image build was already in progress. This caused the deployment of the pipeline to fail. With this fix, the deploy task command is now replaced with the oc rollout status command which waits for the in-progress deployment to finish.

  • Support for APP_NAME parameter is now added in pipeline templates.

  • Previously, the pipeline template for Java S2I failed to look up the image in the registry. With this fix, the image is looked up using the existing image pipeline resources instead of the user provided IMAGE_NAME parameter.

  • All the OpenShift Pipelines images are now based on the Red Hat Universal Base Images (UBI).

  • Previously, when the pipeline was installed in a namespace other than tekton-pipelines, the tkn version command displayed the pipeline version as unknown. With this fix, the tkn version command now displays the correct pipeline version in any namespace.

  • The -c flag is no longer supported for the tkn version command.

  • Non-admin users can now list the cluster trigger bindings.

  • The event listener CompareSecret function is now fixed for the CEL Interceptor.

  • The list, describe, and start subcommands for tasks and cluster tasks now correctly display the output in case a task and cluster task have the same name.

  • Previously, the OpenShift Pipelines Operator modified the privileged security context constraints (SCCs), which caused an error during cluster upgrade. This error is now fixed.

  • In the tekton-pipelines namespace, the timeouts of all task runs and pipeline runs are now set to the value of default-timeout-minutes field using the config map.

  • Previously, the pipelines section in the web console was not displayed for non-admin users. This issue is now resolved.
