[Container Device Interface
(CDI)](https://github.com/cncf-tags/container-device-interface/blob/main/SPEC.md)
is a standardized mechanism for container runtimes to create containers which
are able to interact with third party devices.
CDI is currently only supported for Linux containers and is enabled by default
since Docker Engine 28.3.0.
With CDI, device configurations are declaratively defined using a JSON or YAML
file. In addition to enabling the container to interact with the device node,
it also lets you specify additional configuration for the device, such as

### Enable CDI devices

### Configure CDI devices
Container Device Interface (CDI) is a
[standardized](https://github.com/cncf-tags/container-device-interface/blob/main/SPEC.md)
mechanism for container runtimes to create containers which are able to
interact with third party devices.
CDI is currently only supported for Linux containers and is enabled by default
since Docker Engine 28.3.0.
The Docker daemon supports running containers with CDI devices if the requested
device specifications are available on the filesystem of the daemon.
The default specification directors are:
The default specification directories are:
- `/etc/cdi/` for static CDI Specs
- `/var/run/cdi` for generated CDI Specs
Alternatively, you can set custom locations for CDI specifications using the
#### Set custom locations
To set custom locations for CDI specifications, use the
`cdi-spec-dirs` option in the `daemon.json` configuration file, or the
`--cdi-spec-dir` flag for the `dockerd` CLI.
`--cdi-spec-dir` flag for the `dockerd` CLI:
```json
{
"features": {
"cdi": true
},
"cdi-spec-dirs": ["/etc/cdi/", "/var/run/cdi"]
}
```
When CDI is enabled for a daemon, you can view the configured CDI specification
directories using the `docker info` command.
You can view the configured CDI specification directories using the `docker info` command.
#### Disable CDI devices
The feature in enabled by default. To disable it, use the `cdi` options in the `deamon.json` file:
```json
"features": {
"cdi": false
},
```
To check the status of the CDI devices, run `docker info`.
