Service account to run Pipeline

If you install Tekton using the OpenShift Pipeline Operator on OCP4, a service account pipeline is already created and you can skip the following commands.

Create a service account like pipeline

oc create serviceaccount pipeline
oc adm policy add-scc-to-user privileged -z pipeline
oc adm policy add-role-to-user edit -z pipeline

Create Pipeline Tasks

IMPORTANT: If Tekton version is lower than 0.7.0 then use the tasks from the pre-0.7.0 directory.

• Create pipelines tasks for each environment for example the dev namespace:

  kubectl create -f ibm-garage-tekton-tasks/pre-0.7.0/tasks/ -n dev

• If using Tekton version 0.7.0 or greater use this command instead:

  kubectl create -f ibm-garage-tekton-tasks/tasks/ -n dev

This step will create the following tasks:

• igc-nodejs-tests
• igc-java-gradle-tests
• igc-build-push.yaml
• igc-build-tag-push.yaml
• igc-build-tag-push-ibm.yaml
• igc-deploy
• igc-health-check
• igc-helm-package
• igc-gitops

Create Pipelines

• Create pipelines for each environment for example the dev namespace.

  kubectl create -f ibm-garage-tekton-tasks/pipelines/ -n dev

This step will create following Pipelines:

• igc-java-gradle
• igc-nodejs

Manually run a Pipeline

• The internal container registry service hostname is different for ocp3 and ocp4

  • ocp3: docker-registry.default.svc:5000
  • ocp4: image-registry.openshift-image-registry.svc:5000

• To install the input pipeline resources for the respective application template run the following commands:

  For ocp4:

  OCP=ocp4 kubectl apply -f test/resources/$OCP/

  For ocp3:

  OCP=ocp3 kubectl apply -f test/resources/$OCP/

• Run a pipeline for one of the application templates using the Tekton CLI tkn and the helper script

  Usage: ./test/scripts/run.sh [nodesjs-typescript | nodejs-react | nodejs-angular | java-spring]

  For example to run the pipeline for the application template nodejs-typescript

  ./test/scripts/run.sh nodesjs-typescript

  The script will output the name of the pipelinerun, and a command to follow the logs

  Pipelinerun started: igc-nodejs-run-fqgr7
  
  In order to track the pipelinerun progress run:
  tkn pipelinerun logs igc-nodejs-run-fqgr7 -f -n dev
  

Create Git Webhook

• Create a Git Webhook on the dev namespace using the tekton dashboard.

Now, your pipeline runs whenever the changes are pushed to the repository.
