Hello-Tekton

Use a Tekton pipeline to build and deploy a simple hello world node application with IBM Cloud Devops ( https://cloud.ibm.com/devops).

The .tekton folder contains Tekton Resource definitions that create a Tekton PipelineRun. This "runs" a pipeline that builds a simple node application into an image, scans the image for vulnerabilities, and then deploys the application with IBM Cloud Kubernetes Service.

In order to build and deploy to your own cluster this sample requires parameterization of the following:

  • apikey an IBM Cloud API Key
  • cluster the name of your IKS cluster where you will be deploying the sample app
  • clusterNamespace the namespace in your cluster where the app will be deployed (default: prod)
  • clusterRegion the region where your IKS cluster is located (default: us-south)
  • registryNamespace the IBM Cloud Container Registry namespace where the app image will be built and stored.
  • registryRegion the region where your IBM Cloud Container Registry is located (default: us-south)
  • repository the source git repository where your resources are cloned (default: https://github.com/open-toolchain/hello-tekton). Change this if you are forking this repo
  • revision the branch of the source git repository where your resources are cloned (default: master).

For more information on Tekton Pipelines wih IBM Cloud Devops visit https://cloud.ibm.com/docs/services/ContinuousDelivery?topic=ContinuousDelivery-tekton-pipelines

Note that this example targets the 0.11.2 release of Tekton.

The other branches in this repo contain examples that target different releases. (NOTE: since the IBM Cloud CLI and the k8s versions are constantly upgrading there is no guarantee that all branches in this repo will continue to run forever. The main branch will be kept up-to-date.)

The branches contain:

  • tekton-0.7.0: targets the 0.7.0 tekton release
  • tekton-0.10.1-pvc: targets the 0.10.1 tekton release, uses a pvc to pass info
  • tekton-0.10.1-workspaces: targets the 0.10.1 tekton release, uses a workspace to pass info
  • tekton-0.11.2: targets the 0.11.2 tekton release, uses a workspace to pass info (same as master)
  • tekton-0.11.2-artifactory: same as tekton-0.11.2 + an example of how to use artifactory
