When I pass service name in environment variable in YAML file, that service name is still string, it's not being resolved in real ip address.
Example:
env:
- name: ES
value: elasticsearchThanks
You should be able to use it directly and it should resolve fine:
curl $ESIf you use it inside your application it should also work.
Just consider that Kubernetes uses its internal DNS and the that "elasticsearch" name should only work inside the same namespace. In fact it will resolve to:
elasticsearch.<namespace>.svc.cluster.local.
If your elastic service is running in different namespace, make sure you use elastic.<target_namespace>.
