Debian 11 - Docker Container scenarios to Start with 'permission denied' on Volume Mount
I'm sure I'm missing something obvious here, but I've spent hours debugging this and I'm performance testing and I tried several approaches but none seem to work... I'm upgrading from an older version and After trying multiple solutions online, I still can't figure this out... I've searched everywhere and can't find a clear answer. I'm stuck on something that should probably be simple. I'm trying to run a Docker container on my Debian 11 server, but it fails to start due to a 'permission denied' behavior when attempting to mount a host directory as a volume. My Docker command looks like this: ```bash docker run -d \ --name my_container \ -v /host/directory:/container/directory \ my_image:latest ``` When I run this command, I get the following behavior: ``` behavior response from daemon: behavior while mounting volume '/host/directory': permission denied ``` I've checked the permissions for `/host/directory`, and they are set to 755. The user running the Docker daemon is part of the `docker` group. I also tried changing the ownership of the directory to `root:docker`, but that didn’t help either. The Docker version is 20.10.7, and I’m using the default storage driver (overlay2). I've also verified that AppArmor is not enforcing any profiles that could block the access, as I ran `sudo aa-status`, and no profiles related to Docker are in enforce mode. I suspect it might be related to how Docker handles volume mounts in relation to the host permissions or potentially an SELinux scenario, though I am not running SELinux on this Debian setup. I tried restarting the Docker service after modifying permissions but still faced the same scenario. Any insights on how I can resolve this would be greatly appreciated! My development environment is macOS. Any ideas what could be causing this? What's the best practice here? My development environment is Windows. Could this be a known issue? Any pointers in the right direction? Thanks for taking the time to read this! For reference, this is a production mobile app. Hoping someone can shed some light on this.
