12## Use Docker experimental

14To enable experimental features, start the Docker daemon with the
15`--experimental` flag or enable the daemon flag in the
16`/etc/docker/daemon.json` configuration file:
17
18```json
19{
20 "experimental": true
21}
22```

24You can check to see if experimental features are enabled on a running daemon
25using the following command:
26
27```bash
28$ docker version -f '{{.Server.Experimental}}'
29true
