Docker compose port security

[MathijsNL]

Just want your opinion on this. On some distros it is default behavior to make docker ports that are listening on 0.0.0.0 available to the outside world.

In case this doesn't happen those ports will likely be exposed to at least an internal network.

I would propose to change all listening ip addresses from 0.0.0.0 to 127.0.0.1.

This would be more secure by default. Let me know your thoughts and I can create PR for it if you want.

@MathijsNL this sounds like a good point, we would be happy to review a PR regarding this.
