So, i'm trying to get linkr (a pretty cool short link service) to work in a docker container since 4 hours now to host it on my server. There is no official container because it needs a working database connection and stuff during installation which can only be done via console and (for whatever reason I couldn't find out yet) need to be done while building the container. The problem is, I can't connect it to the database while building the container so there is no database during installation to create tables and stuff and the build will fail. ARGH.
Why the hell would you do this????? Theyre actually saying in their readme there is no dockerfile because the config options are specific to your configuration...?!?!
The thing is entirely written in python, so reading and parsing configfiles on the fly should not really be a problem.

Of course I could ssh into the container and run the installation script but that's not the point.

Docker is not about being lazy.
It's about portability.
Maybe I don't want to bloat my server with your 39579372639 npm dependencies? Or I don't want to install a freakin apache, because I have every other site on nginx and therefore wouldn't work with apache.

AAAAAAAARRRRRRGGHHGGGGG

in the end, I'm probably going to modify the thing to install tables when running the container and giving the first user admin rights instead of prompting to enter credentials for a new admin user.
And yet I didn't even speak python.
