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/
