Mosquitto Docker Compose v2

[vvatelot]

Hello to all, some time ago, @spagnoloG, @nixilb and @martinbra reported a bug in the use of this project. It took me a while to find out and I apologize. Thanks to them for insisting and proposing fixes!

So we upgraded the project from v1.0.0 to v2.0.0. v1.0.0 uses mosquitto 1.6 while v2.0.0 uses mosquitto 2.0. We also took advantage of this to change the structure of local volumes. To migrate from version 1 to version 2, here are the steps to follow:

• Modify the access rights to the log and config directories: sudo chown -R $UID:$GID log config
• When you start your container, use the command UID=$UID GID=$GID docker-compose up -d

Can I use environment variables UID and PID inside the docker compose definition instead of defining them when I run docker compose up? I tried but it seems it keeps trying to chown the volumes to user 1883.

Hello @jpmiller25, there might be a better and cleaner way to do so. For now, it is the best I found out to work with UID and GID. If you find something better, do not hesitate to propose it :)
