init-container-test-1.yaml

# Init containers always complete before main container. If a container fails to start due to the runtime or exists with failure
# It is retried according to the Pod `restartPolicy`.
# If Pod restart policy is set to `Always` then the init containers use restartPolicy `OnFailure`.
