Volume Containers

Copying files from current directory into a volumes container.

# if volume container is not yet created
docker create -v $DATA_DIR --name $DATA_CONTAINER_NAME $IMAGE /bin/true

# example for my znc contianer
docker create -v /znc-data --name znc-data kyleondy/znc /bin/true

# copy the files in
docker run --rm --volumes-from $VOLUME_CONTAINER -v $(pwd):/move --entrypoint /bin/sh {$IMAGE} -c "cp -av /move/* $DESTINATION"
