Cleanup DockerFile to eliminate warnings (#121)
Cleanup DockerFile to eliminate warnings (#121)

Motivation:

When building our docker image a lot of warnings showed up.

Modification:

- Ensure we not try to start services on installation
- Redirect STDERR
- Remove some commented lines

Result:

Less warnings during building the docker image.
