Running container as different user fails with permission denied error

• Changed Config: Using different user to run container

When I use different user other than default root to launch a container I am unable to get it started as it tries to switch to /root directory and gets permission denied.

docker: Error response from daemon: OCI runtime create failed: container_linux.go:348: starting container process caused "chdir to cwd (\"/root\") set in config.json failed: permission denied": unknown.

I have a use case where I allow access to file which has sensitive information only to web user www-data where other users cannot view that file, hence it makes sense to run the container as different user.

In the Dockerfile I see WORKDIR is changed to /root. Removing the line should fix this problem.

Please kindly check and do the needful.

Thank you

The thing is root is default user in docker images used by Cloud Commander, and WORKDIR was set to root as a home directory of root user, as shown in example:

docker run -t --rm -v ~:/root -v /:/mnt/fs -w=/root -p 8000:8000 coderaiser/cloudcmd

To have ability to see home directory files straight after run. Anyways there is an workdir option that can be used to set any workdir you want.

Fixed with d16e345 🔨. Landed in v11.8.2 🎉.

Is it works for you?
