Docker - cannot mount volume over existing file, file exists

Question

I\'m trying to build a data container for my application in Docker. I run this command to expose some volumes:

docker run --name svenv.nl-data -v /etc/environmen         


        

Answer 1

You should use:

-v /etc/environment:/etc/environment

instead of:

-v /etc/environment

The former maps container volume to the host volume. The latter tries to create a new volume at /etc/environment and fails since this directory already exists.
