# 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
|
|
|
|
Experimental features are now included in the standard Docker binaries as of
|
|
version 1.13.0.
|
|
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:
|
|
|
|
```json
|
|
{
|
|
"experimental": true
|
|
}
|
|
```
|
|
|
|
You can check to see if experimental features are enabled on a running daemon
|
|
using the following command:
|
|
|
|
```bash
|
|
$ docker version -f '{{.Server.Experimental}}'
|
|
true
|
|
```
|
|
|
|
## Current experimental features
|
|
|
|
Docker service logs command to view logs for a Docker service. This is needed in Swarm mode.
|
|
Option to squash image layers to the base image after successful builds.
|
|
Checkpoint and restore support for Containers.
|
|
Metrics (Prometheus) output for basic container, image, and daemon operations.
|
|
|
|
* The top-level [docker deploy](../docs/reference/commandline/deploy.md) command. The
|
|
`docker stack deploy` command is **not** experimental.
|
|
* [`docker service logs` command](../docs/reference/commandline/service_logs.md)
|
|
* [`--squash` option to `docker build` command](../docs/reference/commandline/build.md##squash-an-images-layers---squash-experimental-only)
|
|
* [External graphdriver plugins](../docs/extend/plugins_graphdriver.md)
|
|
* [Ipvlan Network Drivers](vlan-networks.md)
|
|
* [Distributed Application Bundles](docker-stacks-and-bundles.md)
|
|
* [Checkpoint & Restore](checkpoint-restore.md)
|
|
* [Docker build with --squash argument](../docs/reference/commandline/build.md##squash-an-images-layers---squash-experimental-only)
