How specify the size of a shared Docker volume?
It is possible to specify the size limit while creating the docker volume using size
as per the documentation
Here is example command provided in the documentation to specify the same
docker volume create -d flocker -o size=20GB my-named-volume
UPDATE Some more examples from git repository:
The built-in local driver on Linux accepts options similar to the linux mount command:
$ docker volume create --driver local --opt type=tmpfs --opt device=tmpfs --opt o=size=100m,uid=1000
Another example:
$ docker volume create --driver local --opt type=btrfs --opt device=/dev/sda2
Using Docker Compose I was able to do it the following way:
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
