docker volume create (original) (raw)
| Description | Create a volume |
|---|---|
| Usage | docker volume create [OPTIONS] [VOLUME] |
Creates a new volume that containers can consume and store data in. If a name is not specified, Docker generates a random name.
| Option | Default | Description |
|---|---|---|
| --availability | active | API 1.42+ SwarmCluster Volume availability (active, pause, drain) |
| -d, --driver | local | Specify volume driver name |
| --group | API 1.42+ SwarmCluster Volume group (cluster volumes) | |
| --label | Set metadata for a volume | |
| --limit-bytes | API 1.42+ SwarmMinimum size of the Cluster Volume in bytes | |
| -o, --opt | Set driver specific options | |
| --required-bytes | API 1.42+ SwarmMaximum size of the Cluster Volume in bytes | |
| --scope | single | API 1.42+ SwarmCluster Volume access scope (single, multi) |
| --secret | API 1.42+ SwarmCluster Volume secrets | |
| --sharing | none | API 1.42+ SwarmCluster Volume access sharing (none, readonly, onewriter, all) |
| --topology-preferred | API 1.42+ SwarmA topology that the Cluster Volume would be preferred in | |
| --topology-required | API 1.42+ SwarmA topology that the Cluster Volume must be accessible from | |
| --type | block | API 1.42+ SwarmCluster Volume access type (mount, block) |
Create a volume and then configure the container to use it:
The mount is created inside the container's /world directory. Docker doesn't support relative paths for mount points inside the container.
Multiple containers can use the same volume. This is useful if two containers need access to shared data. For example, if one container writes and the other reads the data.
Volume names must be unique among drivers. This means you can't use the same volume name with two different drivers. Attempting to create two volumes with the same name results in an error:
If you specify a volume name already in use on the current driver, Docker assumes you want to reuse the existing volume and doesn't return an error.
Driver-specific options (-o, --opt)
Some volume drivers may take options to customize the volume creation. Use the-o or --opt flags to pass driver options:
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 accepts no options on Windows. On Linux and with Docker Desktop, the local driver accepts options similar to the Linux mountcommand. You can provide multiple options by passing the --opt flag multiple times. Some mount options (such as the o option) can take a comma-separated list of options. Complete list of available mount options can be foundhere.
For example, the following creates a tmpfs volume called foo with a size of 100 megabyte and uid of 1000.
