Docker In Docker (DIND) Kubernetes Cluster Hosted task example usage

The sample-docker-dind-cluster sub-directory contains an dind-cluster-no-resources EventListener definition that you can include in your Tekton pipeline configuration to run an example usage of the icr-execute-in-dind-cluster and icr-check-va-scan. This pipeline definition uses the task's parameter image-url to provide the information on image to build and scan.

Note: this sample also relies on the clone-repo task to clone the application to containerize.

1. Create or update a toolchain to include:

   • the git repository that you want to clone, which can be private
   • the repository containing this Tekton task
   • a Tekton pipeline definition

   

2. Add the definitions:

   • for the git-clone-repo (git path)
   • for this task and the sample (container-registry and container-registry/sample-docker-dind-cluster paths)

   

3. Add the environment properties:

   • apikey to provide an API key used for the ibmcloud login/access
   • build-cluster to provide the kubernetes cluster name that will be used as a build cluster (ie hosting the Docker DinD)
   • image-url to indicate the URL of the image to push to the IBM Cloud Container Registry
   • repository to indicate the git repository url to clone (correspoding to the one integrated in the toolchain)

   

4. Create a manual trigger to start the sample listener

   

5. Run the pipeline

6. Verify that the image was build and pushed by looking at the pipeline run execution log:
