Gitlab aways Readiness probe failed

Start with kubernetes/deploy.sh and the GitLab, PostgreSQL, and Redis manifests listed in the issue, then inspect the GitLab pod with kubectl logs and kubectl describe. Compare the readiness probe configuration with the startup behavior shown in the output; done means the deployed GitLab pod becomes Ready and the probe no longer reports connection refused.
