Configure with env variables

[tboerger]

To make the configuration easier especially in the world of systemd and docker we should make it possible to entirely configure gitea with environment variables. To work around the required variables used within the ssh shell we can generate an environment file for it automatically on application start. That way we can get rid of the requirement of the custom app.ini.

First is that we can indicate one configuration file via command line?

[tboerger]

The configuration file can already be defined at least via an environment variable. But I would like to provide flags for the available options and also bind them to environment variables so that we get the full flexibility out of that.

This will be a bitch, we'd have to build a new module on top of the current ini-loader 😒

[tboerger]

At least I will give it a try and then we will see how complex that gets.

There are Go packages (I thought envflags is an example) that automatically load configs, in order of increasing priority, a config file, env flags and command line flags. Config variables only have to be defined once and they can be set in all three ways.

We already use codegangsta cli which provides most scenarios

And additionally to that I can think of dotenv.

any update?

[tboerger]

I think setting it to 1.2.0 is fine so far unless somebody provides a PR in time.
