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 PipelineResource YAML file with a PipelineResource that defines the Git repository and reference for the PetClinic application as follows:

apiVersion: tekton.dev/v1alpha1
kind: PipelineResource
metadata:
  name: petclinic-git
spec:
  type: git
  params:
  - name: url
    value: https://github.com/spring-projects/spring-petclinic

Add another PipelineResource, which defines the OpenShift internal registry to which you want to push the PetClinic image, to the YAML file as shown below, and save it.

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

Create the above pipeline resources as follows:

$ oc create -f https://raw.githubusercontent.com/openshift/pipelines-tutorial/master/pipeline/02-resources.yaml

Verify the resources created as follows:

$ tkn resource ls
