Permission implementing Docker container accessing mounted host volume on CentOS 8
I'm getting frustrated with I'm converting an old project and I'm relatively new to this, so bear with me... I just started working with I'm running a Docker container on CentOS 8 that needs to access a mounted volume from the host machine, but I'm working with a permission denied behavior. The volume is mounted to `/mnt/data` on the host, and the Docker container is set up to use this directory as a volume. However, when I attempt to write to the volume from within the container, I get the following behavior: ``` behavior: EACCES: permission denied, open '/mnt/data/testfile.txt' ``` I've verified that the mounted directory has the correct permissions on the host: ```bash ls -ld /mnt/data ``` This returns: ``` drwxr-xr-x. 2 root root 4096 Oct 10 12:00 /mnt/data ``` I also added the `--user` flag in my Docker run command to match the UID and GID of the host user: ```bash docker run -v /mnt/data:/data --user $(id -u):$(id -g) my-container-image ``` Despite this, I still want to write to the `/data` directory inside the container. I've also tried using the `:z` option when mounting the volume to adjust the SELinux context: ```bash docker run -v /mnt/data:/data:z my-container-image ``` However, that didn't resolve the scenario either. I'm not sure if this is related to SELinux policies or if there's something else at play. Any suggestions on how to resolve these permission issues would be greatly appreciated! Is there a better approach? Has anyone else encountered this? I'm using Bash 3.9 in this project. Any help would be greatly appreciated! This is part of a larger REST API I'm building. I recently upgraded to Bash 3.10.
