This makes it so when calling `docker run --rm`, or `docker rm -v`, only volumes specified without a name, e.g. `docker run -v /foo` instead of `docker run -v awesome:/foo` are removed. Note that all volumes are named, some are named by the user, some get a generated name. This is specifically about how the volume was specified on `run`, assuming that if the user specified it with a name they expect it to persist after the container is cleaned up.

NAME
docker-rm - Remove one or more containers
SYNOPSIS
docker rm [-f|--force] [-l|--link] [-v|--volumes] CONTAINER [CONTAINER...]
DESCRIPTION
docker rm will remove one or more containers from the host node. The container name or ID can be used. This does not remove images. You cannot remove a running container unless you use the -f option. To see all containers on a host use the docker ps -a command.
OPTIONS
--help Print usage statement
-f, --force=true|false Force the removal of a running container (uses SIGKILL). The default is false.
-l, --link=true|false Remove the specified link and not the underlying container. The default is false.
-v, --volumes=true|false Remove the volumes associated with the container. The default is false.
EXAMPLES
Removing a container using its ID
To remove a container using its ID, find either from a docker ps -a command, or use the ID returned from the docker run command, or retrieve it from a file used to store it using the docker run --cidfile:
docker rm abebf7571666
Removing a container using the container name
The name of the container can be found using the docker ps -a command. The use that name as follows:
docker rm hopeful_morse
Removing a container and all associated volumes
$ docker rm -v redis redis
This command will remove the container and any volumes associated with it. Note that if a volume was specified with a name, it will not be removed.
$ docker create -v awesome:/foo -v /bar --name hello redis hello $ docker rm -v hello
In this example, the volume for /foo will remain in tact, but the volume for
/bar will be removed. The same behavior holds for volumes inherited with
--volumes-from.
