containerd, the industry-standard container runtime, uses snapshotters instead
|
|
of the classic storage drivers for storing image and container data.
|
|
While the `overlay2` driver still remains the default driver for Docker Engine,
|
|
you can opt in to using containerd snapshotters as an experimental feature.
|
|
|
|
To learn more about the containerd image store and its benefits, refer to
|
|
[containerd image store on Docker Desktop](../desktop/containerd/index.md).
|
|
|
|
## Enable containerd image store on Docker Engine
|
|
|
|
Switching to containerd snapshotters causes you to temporarily lose images and
|
|
containers created using the classic storage drivers.
|
|
Those resources still exist on your filesystem, and you can retrieve them by
|
|
turning off the containerd snapshotters feature.
|
|
|
|
The following steps explain how to enable the containerd snapshotters feature.
|
|
|
|
1. Add the following configuration to your `/etc/docker/daemon.json`
|
|
configuration file:
|
|
|
|
```json
|
|
{
|
|
"features": {
|
|
"containerd-snapshotter": true
|
|
}
|
|
}
|
|
```
|
|
|
|
2. Save the file.
|
|
3. Restart the daemon for the changes to take effect.
|
|
|
|
```console
|
|
$ sudo systemctl restart docker
|
|
```
|
|
|
|
After restarting the daemon, running `docker info` shows that you're using
|
|
containerd snapshotter storage drivers.
|
|
|
|
|
|
```console
|
|
$ docker info -f '{{ .DriverStatus }}'
|
|
[[driver-type io.containerd.snapshotter.v1]]
|
|
```
|
|
|
|
|
|
Docker Engine uses the `overlayfs` containerd snapshotter by default. |
