Tekton CI/CD on OpenShift

The Tekton Pipelines project provides Kubernetes-style resources for declaring CI/CD-style pipelines.

Build and run Nodejs app on OpenShift using a cloud native Tekton Pipeline

Install Tekton Pipelines on your OpenShift environment

oc apply --filename https://storage.googleapis.com/tekton-releases/pipeline/latest/release.yaml

If you would like more detailed install instructions, or if you are installing on OpenShift, then read these instructions from the Tekton Pipelines documentation.

Install the Tekton resources on your OpenShift environment

The Tekton resources are in this openshift/tekton/ directory.

oc apply -f openshift/tekton/

(Optional) You might need to give your ServiceAccount the proper permissions

cat << EOF | oc apply -f -
apiVersion: rbac.authorization.k8s.io/v1
kind: RoleBinding
metadata:
  name: cluster-admin
subjects:
  - kind: ServiceAccount
    name: default
roleRef:
  kind: ClusterRole
  name: cluster-admin
  apiGroup: rbac.authorization.k8s.io
EOF

Run the Tekton Pipeline

Run the Pipeline by creating a PipelineRun resource such as the following:

NAMESPACE=myapp
cat << EOF | oc apply -f -
apiVersion: tekton.dev/v1alpha1
kind: PipelineRun
metadata:
  name: myapp-openshift
spec:
  pipelineRef:
    name: myapp-openshift
  resources:
    - name: source
      resourceSpec:
        type: git
        params:
          - name: revision
            value: master
          - name: url
            value: https://github.com/ncskier/myapp
    - name: image
      resourceSpec:
        type: image
        params:
          - name: url
            value: image-registry.openshift-image-registry.svc:5000/${NAMESPACE}/myapp:latest
EOF

View the deployed Nodejs app

Get the URL for your route with oc get route myapp, and open the route URL in your web browser.

If you would like to view the PipelineRun logs, then read these instructions from the Tekton Pipelines documentation.
