errors, turn validation off with --validate=false

In the documentation for running on Minikube a test-pull.yaml is created which includes the imagePullSecrets to fetch from Docker Store where the Terracotta DB images are located. In the actual yaml files in the repository though, this information is missing. Creating them thus fails.
