Allow a configurable log level

[michaelkrieger]

Currently there is no way to override the log level from the default.

Note: I could have used LOGLEVEL="${LOGLEVEL:-info}", but in case the shell isn't (always) bash, this is more compatible.

Hi @michaelkrieger thank's for your pull request

LOGLEVEL="${LOGLEVEL:-info}" could be a cleaner solution may be we should force bash as the default shell considering that bash is installed by default

docker-deluge/Dockerfile

Line 17 in d33dab0

bash \

It's look like we have 2 solutions to set bash as the default SHELL

using ENV :

ENV SHELL /bin/bash

or using SHELL
https://docs.docker.com/engine/reference/builder/#shell
moby/moby#7281 (comment)

SHELL ["/bin/bash", "-c"]

I don't know what is the best approach
