If you want to use Volume with Containers, please refer this url.

Volumes are often a better choice than persisting data in a container’s writable layer, because a volume does not increase the size of the containers using it, and the volume’s contents exist outside the lifecycle of a given container.

When its comes to a question of How to specify the size limit while creating the docker volume?

As we can see it’s possible to create docker volumes with a predefined size and do it from Docker API which is especially useful if you’re creating new volumes from some container with mounted docker socket and don’t have access to the host.

But Currently, Its looks like only tmpfs mounts support disk usage limitations.

It is possible to specify the size limit while creating the docker volume using size param with –opt options.

	# docker -v
	Docker version 19.03.9, build 9d988398e7
	# docker volume create -h
	Flag shorthand -h has been deprecated, please use --help
	Usage: docker volume create [OPTIONS] [VOLUME]
	Create a volume
	Options:
	-d, --driver string Specify volume driver name (default "local")
	--label list Set metadata for a volume
	-o, --opt map Set driver specific options (default map[])
	Docker Command Example
	Some of the storage driver plugins which is used for limiting a volume size are
	- flocker
	- local
	- convoy
	Here is example command provided in the documentation to specify the same
	$ docker volume create --driver flocker -o size=20GB my-named-volume
	$ docker volume create --driver local --opt type=tmpfs --opt device=tmpfs --opt o=size=100m,uid=1000
	$ docker volume create --driver local --opt type=btrfs --opt device=/dev/sda2
	$ docker volume create --driver local --opt type=tmpfs --opt device=tmpfs --opt o=size=100m,uid=1000 foo
	$ docker volume create --driver convoy --opt size=100m test
	Docker Compose Example
	volumes:
	tmpfs:
	# For details, see:
	# https://docs.docker.com/engine/reference/commandline/volume_create/#driver-specific-options
	driver: local
	driver_opts:
	o: "size=$TMPFS_SIZE"
	device: tmpfs
	type: tmpfs
