Hello,

I want to use the Kubernetes Operator for my own Cluster. But it fails everytime I deploy the Elasticseach Quickstart.

It fails with:

```auto
Error from server (InternalError): error when creating "STDIN": Internal error occurred: failed calling admission webhook "validation.elasticsearch.elastic.co": Post https://elastic-webhook-service.elastic-system.svc:443/validate-elasticsearches?timeout=30s: Service Unavailable

```

Followed this guide for getting started:

Hi I am getting same error.

I suppose it has to do something with internet connectivity. My servers are behind a proxy and seems like kubernetes is not aware of it.  
But in the end I need to run it in an air gap system with private registry.

Is your kubernetes cluster also behind a proxy or without internet connectivity?
