4.6. Running a Pipeline

A PipelineRun starts a Pipeline and ties it to the Git and image resources that should be used for the specific invocation. It automatically creates and starts the TaskRuns for each Task in the Pipeline.

Procedure

  1. Start the Pipeline for the back-end application: 

    $ tkn pipeline start build-and-deploy -w name=shared-workspace,claimName=source-pvc -p deployment-name=vote-api -p git-url=http://github.com/openshift-pipelines/vote-api.git -p IMAGE=image-registry.openshift-image-registry.svc:5000/pipelines-tutorial/vote-api

    Note the PipelineRun ID returned in the command output.

  2. Track the PipelineRun progress: 

    $ tkn pipelinerun logs <pipelinerun ID> -f

  3. Start the Pipeline for the front-end application: 

    $ tkn pipeline start build-and-deploy -w name=shared-workspace,claimName=source-pvc -p deployment-name=vote-api -p git-url=http://github.com/openshift-pipelines/vote-ui.git -p IMAGE=image-registry.openshift-image-registry.svc:5000/pipelines-tutorial/vote-ui

    Note the PipelineRun ID returned in the command output.

  4. Track the PipelineRun progress: 

    $ tkn pipelinerun logs <pipelinerun ID> -f

  5. After a few minutes, use tkn pipelinerun list command to verify that the Pipeline ran successfully by listing all the PipelineRuns: 

    $ tkn pipelinerun list

    The output lists the PipelineRuns: 

     NAME                         STARTED      DURATION     STATUS
 build-and-deploy-run-xy7rw   1 hour ago   2 minutes    Succeeded
 build-and-deploy-run-z2rz8   1 hour ago   19 minutes   Succeeded

  6. Get the application route: 

    $ oc get route vote-ui --template='http://{{.spec.host}}'

    Note the output of the previous command. You can access the application using this route.

  7. To rerun the last PipelineRun, using the PipelineResources and ServiceAccount of the previous Pipeline, run: 

    $ tkn pipeline start build-and-deploy --last
