Mount Multiple Data Volumes and Multiple Data Volume Containers in Docker

Multiple Data Volumes from a Single Container

Create and run multiple data volumes in a container:

$ docker run -d --name vol -v /vol1 -v /vol2 ubuntu

Mount the data volumes in a new container:

$ docker run -it --rm --name foo --volumes-from=vol ubuntu

Both volumes will be mounted under the root directory as /vol1 and /vol2.

Multiple Data Volume Containers

Create and run multiple data volume containers:

$ for i in {1..2}; do docker run -d --name vol${i} -v /vol${i} ubuntu; done

Mount multiple data volume containers:

$ docker run -it --rm --name foo --volumes-from=vol1 --volumes-from=vol2 ubuntu

Now there are also two volumes mounted under the root directory as /vol1 and /vol2, one from each container.

Multiple Data Volume Containers But Sharing the Same Data Volume Name

Create multiple data volume containers with the same data volume name /vol:

$ for i in {1..2}; do docker run -d --name vol${i} -v /vol ubuntu; done

Mount multiple data volume containers:

$ docker run -it --rm --name foo --volumes-from=vol1 --volumes-from=vol2 ubuntu
