# 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.
|
|
|
|
## Install Docker experimental
|
|
|
|
Unlike the regular Docker binary, the experimental channels is built and
|
|
updated nightly on https://experimental.docker.com. From one day to the
|
|
next, new features may appear, while existing experimental features may be
|
|
refined or entirely removed.
|
|
|
|
1. Verify that you have `curl` installed.
|
|
|
|
$ which curl
|
|
|
|
If `curl` isn't installed, install it after updating your manager:
|
|
|
|
$ sudo apt-get update
|
|
$ sudo apt-get install curl
|
|
|
|
2. Get the latest Docker package.
|
|
|
|
$ curl -sSL https://experimental.docker.com/ | sh
|
|
|
|
The system prompts you for your `sudo` password. Then, it downloads and
|
|
installs Docker and its dependencies.
|
|
|
|
>**Note**: If your company is behind a filtering proxy, you may find that the
|
|
>`apt-key`
|
|
>command fails for the Docker repo during installation. To work around this,
|
|
>add the key directly using the following:
|
|
>
|
|
> $ curl -sSL https://experimental.docker.com/gpg | sudo apt-key add -
|
|
|
|
3. Verify `docker` is installed correctly.
|
|
|
|
$ sudo docker run hello-world
|
|
|
|
This command downloads a test image and runs it in a container.
|
|
|
|
### Get the Linux binary
|
|
To download the latest experimental `docker` binary for Linux,
|
|
use the following URLs:
|
|
|
|
https://experimental.docker.com/builds/Linux/i386/docker-latest
|
|
|
|
https://experimental.docker.com/builds/Linux/x86_64/docker-latest
|
|
|
|
After downloading the appropriate binary, you can follow the instructions
|
|
[here](https://docs.docker.com/installation/binaries/#get-the-docker-binary) to run the `docker` daemon.
|
|
|
|
> **Note**
|
|
>
|
|
> 1) You can get the MD5 and SHA256 hashes by appending .md5 and .sha256 to the URLs respectively
|
|
>
|
|
> 2) You can get the compressed binaries by appending .tgz to the URLs
|
|
|
|
### Build an experimental binary
|
|
You can also build the experimental binary from the standard development environment by adding
|
|
`DOCKER_EXPERIMENTAL=1` to the environment where you run `make` to build Docker binaries. For example,
|
|
to build a Docker binary with the experimental features enabled:
|
|
|
|
$ DOCKER_EXPERIMENTAL=1 make binary
|
|
|
|
## Current experimental features
|
|
|
|
* [External graphdriver plugins](plugins_graphdriver.md)
|
|
* [User namespaces](userns.md)
|
|
|
|
## How to comment on an experimental feature
|
|
|
|
Each feature's documentation includes a list of proposal pull requests or PRs associated with the feature. If you want to comment on or suggest a change to a feature, please add it to the existing feature PR.
