Enhancement: Add support for Docker

[fabianhick]

Running travelynx within a Docker container or with docker-compose would greatly improve setup and operation of the service.

Agreed; I don't have Docker experience myself though. If you don't mind, I'd appreciate a pull request providing a Dockerfile or similar. I'll gladly help, but would prefer if someone with actual Docker experience is involved.

I just tried to pack it into a container, but unfortunately I have been unable to access the application after starting it up, because it keeps saying "raptor not found"...
What could be the reason for that?

[derf]

That probably means that it's unable to find templates/landingpage.html.ep and templates/layouts/default.html.up. Is your working directory set to the repository root (i.e., the directory where templates/ resides)?

You should find more information in the Mojolicious debug output, in my case it ends up in /var/log/daemon.log

[fabianhick]

Now it is able to find those templates, but now it is unable to load static files...
Each static asset creates a "raptor not found" error.
The logs don't show anything useful either.
