[BUG] docker compose fails as non-root #11675
Description
Description
I tried to host Akkoma, lightweight Mastodon alternative. It requires me to create new, non-root user like this:
sudo useradd -r -s /bin/false -m -d /var/lib/akkoma -U akkoma
Then, I added akkoma to docker group, and logged out.
When I'm on root, everything works perfectly, but when I switch to akkoma user:
sudo -Hu akkoma $SHELL
Docker is working, but Docker Compose not.
Only one subcommand is working: version
I'm getting this panic message:
panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x18 pc=0x1c53a8d]

Steps To Reproduce
- Clone Akkoma repository
- Create
akkomauser & re-log - Switch to
akkomauser and update .env:
echo "DOCKER_USER=$(id -u):$(id -g)" >> .env - Try to run the build script
./docker-resources/build.sh
Build script content:
#!/bin/sh
docker compose build --build-arg UID=$(id -u) --build-arg GID=$(id -g) akkoma
docker compose build --build-arg UID=$(id -u) --build-arg GID=$(id -g) db- Encounter an error
