I am following the quick start guide: https://www.elastic.co/guide/en/cloud-on-k8s/current/k8s-quickstart.html
When I want to deploy the single node elasticsearch I get following error:
Internal error occurred: failed calling webhook "validation.elasticsearch.elastic.co": Post https://elastic-webhook-service.elastic-system.svc:443/validate-elasticsearches?timeout=30s: Service Unavailable
I assume that the problem is that my cluster is behind a proxy server. It can access a private docker registry and can communicate to internet via proxy. https_proxy is set in docker config and in environment. But later on production there will be NO proxy available.
Should ECK work in air-gapped-systems?
