Graylog won't start, says configuration file is missing

[cmerkle]

When trying to run the docker compose stack, I get the following errors in the graylog docker logs saying that the graylog.conf file is missing. I was under the impression that I could completely configure graylog with env variables but it seems like it will not start without a conf file.

Okay so I was able to figure this out, due to graylog just being trash and having just plain wrong outdated messed up and difficult to understand docs, you need to mount the /usr/share/graylog/data/config make the UID of graylog (1100) has full access to it and then download the following two config files:

sudo chown -R 1100:1100 <path/to/the/config/mountpoint>

sudo wget https://raw.githubusercontent.com/Graylog2/graylog-docker/6.0/config/graylog.conf
sudo wget https://raw.githubusercontent.com/Graylog2/graylog-docker/6.0/config/log4j2.xml

If you then restart graylog, you should at least get rid of the greylog config error, but holy **** I've never had such a complicated and so little documented software setup than graylog.

100% with you. Graylog is such a hot mess. Seriously wondering if it is worth it for just monitoring. How do they mess up a docker image so badly?
