1# Docker Experimental Features
2
3This page contains a list of features in the Docker engine which are
4experimental. Experimental features are **not** ready for production. They are
5provided for test and evaluation in your sandbox environments.
6
7The information below describes each feature and the GitHub pull requests and
8issues associated with it. If necessary, links are provided to additional
9documentation on an issue. As an active Docker user and community member,
10please feel free to provide any feedback on these features you wish.

12## Use Docker experimental
13
14Experimental features are now included in the standard Docker binaries as of
15version 1.13.0.
16To enable experimental features, start the Docker daemon with the
17`--experimental` flag or enable the daemon flag in the
18`/etc/docker/daemon.json` configuration file:
19
20```json
21{
22 "experimental": true
23}
24```
25
26You can check to see if experimental features are enabled on a running daemon
27using the following command:
28
29```bash
30$ docker version -f '{{.Server.Experimental}}'
31true
32```
