Docker install permissions

[MasterJubei]

I am having problems with the default instructions, they are not very comprehensive for someone new to docker. On the matrix server: I am running as root Made /etc/dimension as root docker pull turt2live/matrix-dimension Then created /etc/dimension/config.yaml as root I put the default configuration there, but which parameters must be changed for it to not just exit immediately?

The only thing I changed first was to replace the old database with:

database:
    file: "/data/dimension.db"
    botData: "/data/bot.json"

However when I run docker run -d --name dimension -p 127.0.0.1:8184:8184 -v /etc/dimension:/data turt2live/matrix-dimension When I check the logs with: docker logs dimension I get:

root@matrix:/etc/dimension# docker logs dimension
internal/fs/utils.js:230
    throw err;
    ^

What should I change? I tried asking on matrix:matrix.org but nobody replied. Thanks

The problems you're having might be related to using /etc/dimension, since that directory probably requires root access. I think it would be best to just use a directory under your checkout of dimension, for example ./data.

The docker command then becomes:

cd /path/to/matrix-dimension
docker run -d --name dimension -p 127.0.0.1:8184:8184 -v ./data:/data turt2live/matrix-dimension

I too thought it was confusing to use /etc/dimension, specially considering that directory is specific to UNIX systems, Windows hosts won't have it. Probably the docs could be updated to use something like ./data instead.

For future reference: it seems UID & GID 1000 are used (inherited from docker.io/node images).
