Clone repo, build docker image and push docker image to Docker Hub using Tekton pipeline using Buildah

This is a simple sample project to demonstrate how to clone source from Git repo, build docker image and push that docker image to Docker Hub using Tekton pipeline using Buildah.

Used Tekton resources in this project

• git-clone task [https://hub.tekton.dev/tekton/task/git-clone]
• buildah task [https://hub.tekton.dev/tekton/task/buildah]

Required configuration

All the required configuration is in the resources folder.

• Create a secret with your Docker Hub credentials
• Create ServiceAccount with the secret
• Create Role and RoleBinding to allow the ServiceAccount to create resources in the namespace

You need to apply the above resources before running the pipeline. You use the below command to apply the resources.

kubectl apply -f resources/

Troubleshooting
