Docker Experimental Features

This page contains a list of features in the Docker engine which are experimental. Experimental features are not ready for production. They are provided for test and evaluation in your sandbox environments.

The information below describes each feature and the GitHub pull requests and issues associated with it. If necessary, links are provided to additional documentation on an issue. As an active Docker user and community member, please feel free to provide any feedback on these features you wish.

Use Docker experimental

To enable experimental features, start the Docker daemon with the --experimental flag or enable the daemon flag in the /etc/docker/daemon.json configuration file:

{
    "experimental": true
}

You can check to see if experimental features are enabled on a running daemon using the following command:

$ docker version -f '{{.Server.Experimental}}'
true
