Docker Docker Data Volumes Mounting a directory from the local host into a container
Example
It is possible to mount a host directory to a specific path in your container using the -v or --volume command line option. The following example will mount /etc on the host to /mnt/etc in the container:
(on linux) docker run -v "/etc:/mnt/etc" alpine cat /mnt/etc/passwd
(on windows) docker run -v "/c/etc:/mnt/etc" alpine cat /mnt/etc/passwd
The default access to the volume inside the container is read-write. To mount a volume read-only inside of a container, use the suffix :ro:
docker run -v "/etc:/mnt/etc:ro" alpine touch /mnt/etc/passwd
