Is there a way to access the internal dns server, to be able to resolve containers inside of it?
Inside the cluster, the DNS works and you can reach a container via this:
elasticsearch.backend.svc.cluster.local
However, when on the host it can’t reach it, because of the dns server:
Validation failed in API: url elasticsearch.backend.svc.cluster.local:9200 unreachable, error: dial tcp: lookup elasticsearch.backend.svc.cluster.local on 8.8.8.8:53: no such host
