Chapter 3. Specifying remote pipelines, tasks, and step actions using resolvers

Pipelines and tasks are reusable blocks for your CI/CD processes. You can reuse pipelines or tasks that you previously developed, or that were developed by others, without having to copy and paste their definitions. These pipelines or tasks can be available from several types of sources, from other namespaces on your cluster to public catalogs.

In a pipeline run resource, you can specify a pipeline from an existing source. In a pipeline resource or a task run resource, you can specify a task from an existing source.

Step actions, defined in StepAction custom resources (CRs), are reusable actions that a single step within a task completes. When specifying a step, you can reference a StepAction definition from an existing source.

In these cases, the resolvers in Red Hat OpenShift Pipelines retrieve the pipeline, task, or StepAction definition from the specified source at run time.

The following resolvers are available in a default installaton of Red Hat OpenShift Pipelines:

Hub resolver: Retrieves a task, pipeline, or StepAction definition from the Pipelines Catalog available on Artifact Hub or Tekton Hub.
Bundles resolver: Retrieves a task, pipeline, or StepAction definition from a Tekton bundle, which is an OCI image available from any OCI repository, such as an OpenShift container repository.
Git resolver: Retrieves a task, pipeline, or StepAction definition from a Git repository. You must specify the repository, the branch, and the path.
HTTP resolver: Retrieves a task, pipeline, or StepAction definition from a remote HTTP or HTTPS URL. You must specify the URL for authentication.
Cluster resolver: Retrieves a task or pipeline that is already created on the same OpenShift Container Platform cluster in a specific namespace.
Note
In OpenShift Pipelines version 1.16, the cluster resolver does not support retrieving StepAction definitions.

An OpenShift Pipelines installation includes a set of standard tasks that you can use in your pipelines. These tasks are located in the OpenShift Pipelines installation namespace, which is normally the openshift-pipelines namespace. You can use the cluster resolver to access the tasks.

OpenShift Pipelines also provides a standard StepAction definition. You can use the HTTP resolver to access this definition.

3.1. Specifying a remote pipeline, task, or step action from a Tekton catalog
Link kopieren

You can use the hub resolver to specify a remote pipeline, task, or StepAction definition that is defined either in a public Tekton catalog of Artifact Hub or in an instance of Tekton Hub.

Important

The Artifact Hub project is not supported with Red Hat OpenShift Pipelines. Only the configuration of Artifact Hub is supported.

3.1.1. Configuring the hub resolver
Link kopieren

You can change the default hub for pulling a resource, and the default catalog settings, by configuring the hub resolver.

Procedure

To edit the TektonConfig custom resource, enter the following command:
```
$ oc edit TektonConfig config
```
In the TektonConfig custom resource, edit the pipeline.hub-resolver-config spec:
```
apiVersion: operator.tekton.dev/v1alpha1
kind: TektonConfig
metadata:
  name: config
spec:
  pipeline:
    hub-resolver-config:
      default-tekton-hub-catalog: Tekton 
```
1
```
      default-artifact-hub-task-catalog: tekton-catalog-tasks 
```
2
```
      default-artifact-hub-pipeline-catalog: tekton-catalog-pipelines 
```
3
```
      defailt-kind: pipeline 
```
4
```
      default-type: tekton 
```
5
```
      tekton-hub-api: "https://my-custom-tekton-hub.example.com" 
```
6
```
      artifact-hub-api: "https://my-custom-artifact-hub.example.com" 
```
7
1
The default Tekton Hub catalog for pulling a resource.
2
The default Artifact Hub catalog for pulling a task resource.
3
The default Artifact Hub catalog for pulling a pipeline resource.
4
The default object kind for references.
5
The default hub for pulling a resource, either artifact for Artifact Hub or tekton for Tekton Hub.
6
The Tekton Hub API used, if the default-type option is set to tekton.
7
Optional: The Artifact Hub API used, if the default-type option is set to artifact.
Important
If you set the default-type option to tekton, you must configure your own instance of the Tekton Hub by setting the tekton-hub-api value.
If you set the default-type option to artifact then the resolver uses the public hub API at https://artifacthub.io/ by default. You can configure your own Artifact Hub API by setting the artifact-hub-api value.

3.1.2. Specifying a remote pipeline, task, or step action using the hub resolver
Link kopieren

When creating a pipeline run, you can specify a remote pipeline from Artifact Hub or Tekton Hub. When creating a pipeline or a task run, you can specify a remote task from Artifact Hub or Tekton Hub. When creating a step within a task, you can reference a remote StepAction definition from Artifact Hub or Tekton Hub.

Procedure

To specify a remote pipeline, task, or StepAction definition from Artifact Hub or Tekton Hub, use the following reference format in the pipelineRef, taskRef, or step.ref spec:

# ...
  resolver: hub
  params:
  - name: catalog
    value: <catalog>
  - name: type
    value: <catalog_type>
  - name: kind
    value: [pipeline|task]
  - name: name
    value: <resource_name>
  - name: version
    value: <resource_version>
# ...

3.4. Specifying a remote pipeline, task, or step action with an authenticated Git API
Link kopieren

You can specify a remote pipeline, task, or StepAction definition from a Git repository by using the Git resolver. The repository must contain a YAML file that defines the pipeline or task. You can securely access repositories by using an authenticated API, which supports user authentication.

3.4.1. Configuring the Git resolver for an authenticated API
Link kopieren

For an authenticated Source Control Management (SCM) API, you must set the configuration for the authenticated Git connection.

You can use Git repository providers that are supported by the go-scm library. Not all go-scm implementations have been tested with the Git resolver, but the following providers are known to work:

github.com and GitHub Enterprise
gitlab.com and self-hosted Gitlab
Gitea
BitBucket Server
BitBucket Cloud

Note

You can configure Git connections by using the authenticated SCM API. You can provide a security token that enables all users on your cluster to access one repository. Additionally, you can specify different SCM providers and tokens for specific pipelines or tasks.
If you configure the Git resolver to use the authenticated SCM API, you can also use anonymous Git clone references to retrieve pipelines and tasks.

Procedure

To edit the TektonConfig custom resource, enter the following command:
```
$ oc edit TektonConfig config
```
In the TektonConfig custom resource, edit the pipeline.git-resolver-config spec:
```
apiVersion: operator.tekton.dev/v1alpha1

3.4.3. Specifying a remote pipeline or task by using the Git resolver with the authenticated SCM API overriding the Git resolver configuration
Link kopieren

When creating a pipeline run, you can specify a remote pipeline from a Git repository by using the authenticated SCM API. When creating a pipeline or a task run, you can specify a remote task from a Git repository. You can override the initial configuration settings in specific pipeline runs or tasks to customize the behavior according to different use cases.

The following example task run references a remote task from a Git repository that overrides the previous resolver configuration:

apiVersion: tekton.dev/v1beta1
kind: TaskRun
metadata:
  name: git-task-reference-demo
spec:
  taskRef:
    resolver: git
    params:
    - name: org
      value: tektoncd
    - name: repo
      value: catalog
    - name: revision
      value: main
    - name: pathInRepo
      value: task/git-clone/0.6/git-clone.yaml

3.6. Specifying a pipeline or task from the same cluster
Link kopieren

You can use the cluster resolver to specify a pipeline or task that is defined in a namespace on the OpenShift Container Platform cluster where Red Hat OpenShift Pipelines is running.

In particular, you can use the cluster resolver to access tasks that OpenShift Pipelines provides in its installation namespace, which is normally the openshift-pipelines namespace.

3.6.1. Configuring the cluster resolver
Link kopieren

You can change the default kind and namespace for the cluster resolver, or limit the namespaces that the cluster resolver can use.

Procedure

To edit the TektonConfig custom resource, enter the following command:
```
$ oc edit TektonConfig config
```
In the TektonConfig custom resource, edit the pipeline.cluster-resolver-config spec:
```
apiVersion: operator.tekton.dev/v1alpha1
kind: TektonConfig
metadata:
  name: config
spec:
  pipeline:
    cluster-resolver-config:

# ...
  resolver: cluster
  params:
  - name: name
    value: <name>
  - name: namespace
    value: <namespace>
  - name: kind
    value: [pipeline|task]

3.7. Tasks provided in the OpenShift Pipelines namespace
Link kopieren

ClusterTask functionality is deprecated since OpenShift Pipelines 1.10 and is planned for removal in a future release. If your pipelines use ClusterTasks, you can re-create them with the tasks that are available from the OpenShift Pipelines installation namespace by using the cluster resolver. However, certain changes are made in these tasks compared to the existing ClusterTasks.

You cannot specify a custom execution image in any of the tasks available in the OpenShift Pipelines installation namespace. These tasks do not support parameters such as BUILDER_IMAGE, gitInitImage, or KN_IMAGE. If you want to use a custom execution image, create a copy of the task and replace the image by editing the copy.

buildah

3.8. Step action provided with OpenShift Pipelines
Link kopieren

OpenShift Pipelines provides a standard StepAction definition that you can use in your tasks. Use the HTTP resolver to reference this definition.

git-clone

The git-clone step action uses Git to initialize and clone a remote repository on a workspace. You can use this step action to define a task that clones a repository at the start of a pipeline that builds or otherwise processes this source code.

To reference this step action in a task, use the HTTP resolver with the following URL:

https://raw.githubusercontent.com/openshift-pipelines/tektoncd-catalog/p/stepactions/stepaction-git-clone/0.4.1/stepaction-git-clone.yaml

Example usage of the git-clone step action in a task

apiVersion: tekton.dev/v1
kind: Task
metadata:
  name: clone-repo-anon
spec:
  params:
  - name: url
    description: The URL of the Git repository to clone
  workspaces:
  - name: output
    description: The git repo will be cloned onto the volume backing this Workspace.
  steps:
  - name: clone-repo-anon-step
    ref:
      resolver: http
      params:
      - name: url
        value: https://raw.githubusercontent.com/openshift-pipelines/tektoncd-catalog/p/stepactions/stepaction-git-clone/0.4.1/stepaction-git-clone.yaml
    params:
    - name: URL
      value: $(params.url)
    - name: OUTPUT_PATH
      value: $(workspaces.output.path)

Table 3.52. Supported parameters for the git-clone step action
Parameter	Description	Type	Default value
`OUTPUT_PATH`	A directory for the fetched Git repository. Cloned repo data is placed in the root of the directory or in the relative path defined by the `SUBDIRECTORY` parameter	`string`
`SSH_DIRECTORY_PATH`	A `.ssh` directory with the private key, `known_hosts`, `config`, and other files as necessary. If you provide this directory, the task uses it for authentication to the Git repository. Bind the workspace providing this directory to a `Secret` resource for secure storage of authentication information.	`string`
`BASIC_AUTH_PATH`	A directory containing a `.gitconfig` and `.git-credentials` files. If you provide this directgory, the task uses it for authentication to the Git repository. Use a `SSH_DIRECTORY_PATH` directory for authentication instead of `BASIC_AUTH_PATH` whenever possible. Bind the workspace providing this directory to a `Secret` resource for secure storage of authentication information.	`string`
`SSL_CA_DIRECTORY_PATH`	A workspace containing CA certificates. If you provide this workspace, Git uses these certificates to verify the peer when interacting with remote repositories using HTTPS.	`string`
`CRT_FILENAME`	Certificate authority (CA) bundle filename in the `ssl-ca-directory` workspace.	`string`	`ca-bundle.crt`
`HTTP_PROXY`	HTTP proxy server (non-TLS requests).	`string`
`HTTPS_PROXY`	HTTPS proxy server (TLS requests).	`string`
`NO_PROXY`	Opt out of proxying HTTP/HTTPS requests.	`string`
`SUBDIRECTORY`	Relative path in the `output` workspace where the task places the Git repository.	`string`
`USER_HOME`	Absolute path to the Git user home directory in the pod.	`string`	`/home/git`
`DELETE_EXISTING`	Delete the contents of the default workspace, if they exist, before running the Git operations.	`string`	`true`
`VERBOSE`	Log the executed commands.	`string`	`false`
`SSL_VERIFY`	The global `http.sslVerify` value. Do not set this parameter to to `false` unless you trust the remote repository.	`string`	`true`
`URL`	Git repository URL.	`string`
`REVISION`	The revision to check out, for example, a branch or tag.	`string`	`main`
`REFSPEC`	The `refspec` string for the repository that the task fetches before checking out the revision.	`string`
`SUBMODULES`	Initialize and fetch Git submodules.	`string`	`true`
`DEPTH`	Number of commits to fetch, a "shallow clone" is a single commit.	`string`	`1`
`SPARSE_CHECKOUT_DIRECTORIES`	List of directory patterns, separated by commas, for performing a "sparse checkout".	`string`

Table 3.53. Results that the git-clone step action returns
Result	Type	Description
`COMMIT`	`string`	The SHA digest of the commit that is at the HEAD of the current branch in the cloned Git repository.
`URL`	`string`	The URL of the repository that was cloned.
`COMMITTER_DATE`	`string`	The epoch timestamp of the commit that is at the HEAD of the current branch in the cloned Git repository.

3.9. About non-versioned and versioned tasks
Link kopieren

The openshift-pipelines namespace includes versioned tasks alongside standard non-versioned tasks. For example, installing the Red Hat OpenShift Pipelines Operator version 1.16 creates the following items:

buildah-1-16-0 versioned task
buildah non-versioned task

Non-versioned and versioned tasks have the same metadata, behavior, and specifications, including params, workspaces, and steps. However, they behave differently when you disable them or upgrade the Operator.

Before adopting non-versioned or versioned tasks as a standard in production environments, cluster administrators might consider their advantages and disadvantages.

Expand

Table 3.54. Advantages and disadvantages of non-versioned and versioned tasks
	Advantages	Disadvantages
Non-versioned tasks	If you prefer deploying pipelines with the latest updates and bug fixes, use non-versioned tasks. Upgrading the Operator upgrades the non-versioned tasks, which consumes fewer resources than multiple versioned tasks.	If you deploy pipelines that use non-versioned tasks, they might break after an Operator upgrade if the automatically upgraded tasks are not backward-compatible.
Versioned tasks	If you prefer pipelines in production that do not change after a version update, use versioned tasks. When you install a new version of the Operator, the versioned tasks from the current minor version and the immediate previous minor version are retained.	If you continue using the earlier versions, you might miss the latest features and critical security updates. After an upgrade, the Operator cannot manage the earlier versioned tasks. If you delete the earlier versions manually, you cannot restore them. After an upgrade, the Operator can delete versioned tasks from versions earlier than the previous minor release. When you install a new version of and the versioned tasks from an earlier version are deleted, pipelines that use the versioned tasks from the earlier version stop working.

Non-versioned and versioned tasks have different naming conventions, and the Red Hat OpenShift Pipelines Operator upgrades them differently.

Expand

Table 3.55. Differences between non-versioned and versioned tasks
	Nomenclature	Upgrade
Non-versioned tasks	Non-versioned tasks only contain the name of the task. For example, the name of the non-versioned task of Buildah installed with Operator v1.16 is `buildah`.	When you upgrade the Operator, it updates the non-versioned tasks with the latest changes. The name remains unchanged.
Versioned tasks	Versioned tasks contain the name, followed by the version as a suffix. For example, the name of the versioned task of Buildah installed with Operator v1.16 is `buildah-1-16-0`.	Upgrading the Operator installs the latest version of versioned tasks, retains the immediate previous version, and deletes the earlier versions. The latest version corresponds to the upgraded Operator. For example, installing Operator 1.18 installs the `buildah-1-18-0` task, retains the `buildah-1-17-0` task, and deletes earlier versions such as `buildah-1-16-0`.
