How to mount a directory in a docker container to the host?
That is the opposite: you can mount an host folder to your container on docker run. I don’t think so. Right now, you can check docker inspect and see if you see your log in the /var/lib/docker/volumes/… associated to the volume from your container. Or you can redirect the result of docker logs to an host file.
