Extended description
Creates a new volume that containers can consume and store data in. If a name is not specified, Docker generates a random name. You create a volume and then configure the container to use it, for example:
$ docker volume create hello hello $ docker run -d -v hello:/world busybox ls /world
The mount is created inside the container’s /src
directory. Docker doesn’t not support relative paths for mount points inside the container.
Multiple containers can use the same volume in the same time period. This is useful if two containers need access to shared data. For example, if one container writes and the other reads the data.
Driver specific options
Some volume drivers may take options to customize the volume creation. Use the -o
or --opt
flags to pass driver options:
$ docker volume create --driver fake --opt tardis=blue --opt timey=wimey
These options are passed directly to the volume driver. Options for different volume drivers may do different things (or nothing at all).
The built-in local
driver on Windows does not support any options.
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
Examples
$ docker volume create hello hello $ docker run -d -v hello:/world busybox ls /world
