Run Ingress as non root

[dhatri308]

Describe the bug
We are currently using version v1.4.6. We want to run ingress as non root . runAsUser: 33/101 but these users have issue with permissions to etc/nginx.

To Reproduce
Steps to reproduce the behavior:

1. Deploy v1.4.6 daemon set
2. In pod definition, have runAsUser: 33/101 in container SecurityContext
3. In pod logs, we see "nginx.go:248] Couldn't create a temp file for the secret file default: open /etc/nginx/secrets/default664345291: permission denied"

Expected behavior
Ingress controller starts fine

Your environment

• Version of the Ingress Controller - v1.4.6
• Version of Kubernetes - 1.11
• Using NGINX

Additional context
We did try adding a shell script and override permissions of /etc/nginx but only owner/root can do this. So the operation cannot be performed. Please suggest.

Unfortunately, it is not possible to run the IC with non-root user in release 1.4.* and release 1.5.*

we recently added support for non-root user in the master branch (#710) and it is available in the IC edge version.

We will include that feature in 1.6.0 release, which we plan for the first half of December.
