Sharing data between containers with data volume containers

There is another feature of Docker volumes that allows you to share the volume(s) mounted in one Docker container with other containers. It is called data volume containers.

Here is an example:

# Step 1docker container run \   --rm -d \   -v data-vol-01:/data/vol1 -v data-vol-02:/data/vol2 \   --name data-container \ vol-demo2:1.0 tail -f /dev/null ...
