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

To the above PipelineResource YAML file, add another PipelineResource that defines the OpenShift internal registry to which you want to push the PetClinic image, 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/resources/petclinic-resources.yaml

Verify the resources created as follows:

$ tkn resource ls

NAME              TYPE    DETAILS
petclinic-git     git     url: https://github.com/spring-projects/spring-petclinic
petclinic-image   image   url: image-registry.openshift-image-registry.svc:5000/pipelines-tutorial/spring-petclinic
