@ -124,7 +124,7 @@ Let's create a new named container with a volume to share.
While this container doesn't run an application, it reuses the `training/postgres`
image so that all containers are using layers in common, saving disk space.
$ sudo docker create -v /dbdata --name dbdata training/postgres
$ sudo docker create -v /dbdata --name dbdata training/postgres /bin/true
You can then use the `--volumes-from` flag to mount the `/dbdata` volume in another container.
