# Red Hat Enterprise Linux 7
|
|
|
|
**Red Hat Enterprise Linux 7** has [shipped with
|
|
Docker](https://access.redhat.com/site/products/red-hat-enterprise-linux/docker-and-containers).
|
|
An overview and some guidance can be found in the [Release
|
|
Notes](https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/7.0_Release_Notes/chap-Red_Hat_Enterprise_Linux-7.0_Release_Notes-Linux_Containers_with_Docker_Format.html).
|
|
|
|
Docker is located in the *extras* channel. To install Docker:
|
|
|
|
1. Enable the *extras* channel:
|
|
|
|
$ sudo subscription-manager repos --enable=rhel-7-server-extras-rpms
|
|
|
|
2. Install Docker:
|
|
|
|
$ sudo yum install docker
|
|
|
|
Additional installation, configuration, and usage information,
|
|
including a [Get Started with Docker Containers in Red Hat
|
|
Enterprise Linux 7](https://access.redhat.com/site/articles/881893)
|
|
guide, can be found by Red Hat customers on the [Red Hat Customer
|
|
Portal](https://access.redhat.com/).

# Red Hat Enterprise Linux 6
|
|
|
|
Docker is available for **RHEL** on EPEL. Please note that
|
|
this package is part of [Extra Packages for Enterprise Linux
|
|
(EPEL)](https://fedoraproject.org/wiki/EPEL), a community effort to
|
|
create and maintain additional packages for the RHEL distribution.
|
|
|
|
Also note that due to the current Docker limitations, Docker is able to
|
|
run only on the **64 bit** architecture.
|
|
|
|
You will need [RHEL
|
|
6.5](https://access.redhat.com/site/articles/3078#RHEL6) or higher, with
|
|
a RHEL 6 kernel version 2.6.32-431 or higher as this has specific kernel
|
|
fixes to allow Docker to work.
|
|
|
|
## Installation
|
|
|
|
Firstly, you need to install the EPEL repository. Please follow the
|
|
[EPEL installation
|
|
instructions](https://fedoraproject.org/wiki/EPEL#How_can_I_use_these_extra_packages.3F).
|
|
|
|
The `docker-io` package provides Docker on EPEL.
|
|
|
|
If you already have the (unrelated) `docker` package
|
|
installed, it will conflict with `docker-io`.
|
|
There's a [bug report](
|
|
https://bugzilla.redhat.com/show_bug.cgi?id=1043676) filed for it.
|
|
To proceed with `docker-io` installation, please remove `docker` first.
|
|
|
|
Next, let's install the `docker-io` package which
|
|
will install Docker on our host.
|
|
|
|
$ sudo yum -y install docker-io
|
|
|
|
To update the `docker-io` package
|
|
|
|
$ sudo yum -y update docker-io
|
|
|
|
Now that it's installed, let's start the Docker daemon.
|
|
|
|
$ sudo service docker start
|
|
|
|
If we want Docker to start at boot, we should also:
|
|
|
|
$ sudo chkconfig docker on
|
|
|
|
Now let's verify that Docker is working.
|
|
|
|
$ sudo docker run -i -t fedora /bin/bash
|
|
|
|
**Done!**
|
|
|
|
Continue with the [User Guide](/userguide/).
|
|
|
|
## Issues?
|
|
|
|
If you have any issues - please report them directly in the
|
|
[Red Hat Bugzilla for docker-io component](
