[dancer-users] Passing environment to dockerized Dancer2

[Mikko Johannes Koivunalho]

Dear Dancer users,

I want to run my Dancer2 application in a docker but I want to run the
docker without mounting any local directories and I want to run the same
container in all environments, not compile it separately for different
environments.

Problem:
How do I pass the environment dependent parts of the configuration to
the docker? I cannot use file `config_local.yaml` because then I would
need to copy that file somehow into the container when it starts.

Possible solution:
I would pass parts of the configuration as environment variables, e.g.
/DB_HOST/ and /SITE_URL/, and then apply these over the values in
config.yaml when I am creating the endpoints.

Suggestion:
Change the command `/config/` (or the underlying file reader function)
so that it can transpose environment variables into config strings, e.g.
plugins->database->connections->main->host = '${DB_HOST}'.
