Docker Docker Data Volumes Creating a named volume
Example
docker volume create --name="myAwesomeApp"
Using a named volume makes managing volumes much more human-readable. It is possible to create a named volume using the command specified above, but it's also possible to create a named volume inside of a docker run command using the -v or --volume command line option:
docker run -d --name="myApp-1" -v="myAwesomeApp:/data/app" myApp:1.5.3
Note that creating a named volume in this form is similar to mounting a host file/directory as a volume, except that instead of a valid path, the volume name is specified. Once created, named volumes can be shared with other containers:
docker run -d --name="myApp-2" --volumes-from "myApp-1" myApp:1.5.3
After running the above command, a new container has been created with the name myApp-2 from the myApp:1.5.3 image, which is sharing the myAwesomeApp named volume with myApp-1. The myAwesomeApp named volume is mounted at /data/app in the myApp-2 container, just as it is mounted at /data/app in the myApp-1 container.
