Problems parsing config file inside container

[heimojuh]

At least with Mattermost 2.1.0 (and 2.2.0 I forked repo and tested) the final config file inside container seems to cause problems, at least I can't get container to run. Using the docker-compose method. At startup the container woes:

When investigating inside container, I get following (not very informative) output:

Which seems to refer to some problem in parsing the config file. I'm using the easiest way possible, running from docker-compose.yml.

I'm also trying to figure this out, but just wanted you to know :) Looks like the most comprehensive mattermost docker image I've yet found :)

What do you know, the "latest" version seems to work :+1: You sir, are superfast :)

[jasl8r]

Yeah I had a whole bunch of changes in progress for alpine and the 2.2 release. I did have a couple configure problems I fixed. I should probably back port it to 2.1.0.

Actually it prolly was a mistake in my config regarding the salts and hashes being too short. embarrassing. Thanks for checking this out, and I'll think I'll just close this one now :)
