docker: Error response from daemon: invalid mount config for type "bind": stat /my/current/folder: permission denied.

[annahung31]

Hi, Thanks for the cool work!

I'm following the tutorial here and working on Ubuntu as a non-root user. But when I run cog run python, I encountered an error:

Running 'python' in Docker with the current directory mounted as a volume...
docker: Error response from daemon: invalid mount config for type "bind": stat  /my/current/folder: permission denied.

It seems related to the mount setting of docker, but I'm not familiar with the docker setting. How can I deal with the error? Where can I find the Dockerfile that cog created and modify the setting? Thanks!

Hi @annahung31!

That's a weird error, I haven't seen that before. I'm guessing the user that the Docker daemon runs under doesn't have permission to read from your cog_test/ directory.

You could try to chmod -R 777 cog_test from the playground/ directory. But I'm not sure that will work.

Is this a cloud instance or a university machine in some sort of managed cluster?

[annahung31]

Thanks for the reply! unfortunately changing the permission doesn't solve the error.

It's a machine in the cluster managed by the lab I belong to. We(me and my colleagues) maintain the machine by ourselves, but only one system administrator for each machine, so most of us are non-root users.

Just a note, I also tried on adding myself into the docker group like the Answer of this page, but it still doesn't work.

[andreasjansson]

Fixed! 🥳

The issue was that the folder was part of an sshfs mount. user_allow_other was disabled which meant that Docker didn't have permission to access it.

Solution: https://serverfault.com/a/947184

We should try to catch errors like this and point to solutions.

Thanks Andreas!

Running 'script/download-weights' in Docker with the current directory mounted as a volume...
[FATAL tini (7)] exec script/download-weights failed: Permission denied
ⅹ exit status 126

Solution was to give 777 permission to all the scripts on my projects so docker daemons can run them, just like @andreasjansson suggested above.
