Defining and creating pipeline resources

PipelineResources are artifacts that are used as inputs to a Task and can be output by a Task.

Procedure

After you create Task`s, create `PipelineResources that contain the specifics of the Git repository and the image registry to be used in the Pipeline during execution as follows:

Create a resources.yaml file and with the `PipelineResource`s that contain the specifics of the Git repository and the image registry to be used in the pipeline during execution.

Create a PipelineResource that defines the Git repository for the frontend application:

apiVersion: tekton.dev/v1alpha1
kind: PipelineResource
metadata:
  name: ui-repo
spec:
  type: git
  params:
    - name: url
      value: http://github.com/openshift-pipelines/vote-ui.git

Create a PipelineResource that defines the OpenShift internal image registry to which you want to push the frontend image:

apiVersion: tekton.dev/v1alpha1
kind: PipelineResource
metadata:
  name: ui-image
spec:
  type: image
  params:
    - name: url
      value: image-registry.openshift-image-registry.svc:5000/pipelines-tutorial/ui:latest

Create a PipelineResource that defines the Git repository for the backend application:

apiVersion: tekton.dev/v1alpha1
kind: PipelineResource
metadata:
  name: api-repo
spec:
  type: git
  params:
    - name: url
      value: http://github.com/openshift-pipelines/vote-api.git

Create a PipelineResource that defines the OpenShift internal image registry to which you want to push the backend image:

apiVersion: tekton.dev/v1alpha1
kind: PipelineResource
metadata:
  name: api-image
spec:
  type: image
  params:
    - name: url
      value: image-registry.openshift-image-registry.svc:5000/pipelines-tutorial/api:latest

Create the Pipeline Resources:

$ oc create -f https://raw.githubusercontent.com/openshift/pipelines-tutorial/master/pipeline/resources.yaml

See the list of resources:

$ tkn resource ls
