Correct way to share socket and other file types between Docker Containers

docker-shared-volume.sh

# create volume for sharing
docker volume create shared-volume

# start one of your containers with the new volume mounted to a directory that the two containers will share
docker \
  run --rm --init \
  -v shared-volume:/shared/files \
  <container_name>

# start the other with the same shared volume mounted to the same filesystem path
docker \
  run --rm --privileged \
  -v shared-volume:/shared/files \
  <other_container_name>
