In case the metrics server in a Kubernetes cluster was not available the Vault Secrets Operator fails to start, because the endpoint for the liveness and readiness probe was also not available (#22). Thanks to @rust84 for pointing out the issue.
Now we are using more useful checks for the readiness and liveness probe (#25):
- Liveness: Returns true if the HTTP server is running.
- Readiness: Returns true if a valid token for Vault is passed to the operator.
