Deploy with Camel-K using Tekton on OCP

Prerequisite

This tutorial assumes the following requirements are met:

• OpenShift 4+ cluster and oc binary tool. See docs here.
• Openshift Pipeline Operator. See docs here.
• Camel K Client Tools - Kamel. See docs here.
• Optional: Tekton CLI. See docs here.

Step 1: Cluster setup

This step will install camel operator on your ocp cluster

kamel install --cluster-setup

Step 2: Create namespace

$ oc new-project camel-pipelines

Step 3: Create permission for serviceaccounts

Use this file on assets/camel-k-pipeline-permissions.yaml

$ oc apply -f camel-k-pipeline-permissions.yaml

Step 4: Create tekton pipeline

Use this file on assets/camel-k-pipeline-task-definition.yaml

$ oc apply -f camel-k-pipeline-task-definition.yaml

Step 5: Trigerring a Pipeline execution

Use this file on assets/pipeline-task-run.yaml

oc apply -f camel-k-pipeline-task-run.yaml

This files contains:

apiVersion: tekton.dev/v1alpha1
kind: PipelineRun
metadata:
  name: camel-k-pipeline-run-1
spec:
  pipelineRef:
    name: camel-k-pipeline
  serviceAccountName: 'camel-k-pipeline' 
  resources:
    - name: source-repo
      resourceRef:
        name: camel-k-examples-git 

Notes: originally it used field serviceAccount, changed to serviceAccountName due to error on tekton parsing the field serviceAccount

After successfully build and deploy, you can find deployed apps on Topology

Step 6 (Optional) : see your deployment using Tekton cli

$ tkn pipeline ls

result will be something like this

NAME               AGE          LAST RUN                  STARTED      DURATION    STATUS
camel-k-pipeline   1 hour ago   camel-k-pipeline-d4vyhr   1 hour ago   3 minutes   Succeeded
