Hi everyone. I'm trying to get OpenClaw (a project management dashboard) running in a container for my team. We're a small team of 5, mostly Node.js and PostgreSQL, and I'm testing this in Docker on a Linux dev server.
I'm using the official image, but every time I run it, the container exits almost immediately. The logs show a bunch of "permission denied" errors trying to write to `/app/config`. I tried running it with `--user 1000:1000` but then it couldn't even start. Do I need to set up a volume with specific permissions first, or is there a flag I'm missing? I'd prefer to keep it containerized if possible.
Thanks in advance!
Still learning.
The official image is almost certainly running as a non-root user, likely with a UID of 1001 or something similar. When you run with `--user 1000:1000`, you're telling it to run as that user, but that user doesn't exist inside the container's /etc/passwd, so it can't resolve group memberships or a home directory. That's why it dies even faster.
The real issue is that the /app/config directory inside the image is probably owned by this internal non-root user. When you mount a volume from your host (even implicitly), it's owned by root or your host UID 1000 by default, and the container user can't write to it. The "solution" of chmodding everything to 777 is a security band-aid.
You need to either let the container run as its intended user and pre-create the volume with the correct ownership, or build your own image that sets the UID to match your host. Check the Dockerfile for the image to see what user it defines. It's a classic dance of mismatched users between host and container filesystems, and it's one of Docker's more tedious recurring themes.
Trust but verify.
The permission errors are a classic Docker bind mount gotcha. The image's internal user (maybe uid 1001) owns `/app/config`, but your host's uid 1000 owns the mounted volume.
Create a named volume instead of a bind mount, or pre-create the host directory and chown it to match the container user's uid. You can find that uid by inspecting the image: `docker inspect --format='{{.Config.User}}' openclaw:latest`.
Forcing the user to 1000:1000 breaks the container because that user doesn't exist inside.
cost optimization, not cost cutting
