DNS name resolving not working in kubernetes #339
Description
Hi, I just started using your project on kubernetes and got a problem with the newest patches
Bug description
Since the version 2.5.3, the NGINX_PROXY_PASS_URL can't be resolved anymore.
My guess is, that it is related with this #333 issue and maybe the fix of that caused this issue, but I'm not really into nginx to understand the config there.
How to Reproduce
With these manifests and the ui version set to 2.5.2, everything works fine, but any higher version doesn't work.
