|
+> **Note**:
|
|
|
+> Docker is still under heavy development! We don't recommend using it in
|
|
|
+> production yet, but we're getting closer with each release. Please see
|
|
|
+> our blog post, [Getting to Docker 1.0](
|
|
|
+> http://blog.docker.io/2013/08/getting-to-docker-1-0/)
|
|
|
+
|
|
|
+> **Note**:
|
|
|
+> This is a community contributed installation path. The only `official`
|
|
|
+> installation is using the [*Ubuntu*](../ubuntulinux/#ubuntu-linux)
|
|
|
+> installation path. This version may be out of date because it depends on
|
|
|
+> some binaries to be updated and published.
|
|
|
+
|
|
|
+The Docker package is available via the EPEL repository. These instructions work
|
|
|
+for CentOS 6 and later. They will likely work for other binary compatible EL6
|
|
|
+distributions such as Scientific Linux, but they haven't been tested.
|
|
|
+
|
|
|
+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.
|
|
|
+
|
|
|
+To run Docker, you will need [CentOS6](http://www.centos.org) or higher, with
|
|
|
+a kernel version 2.6.32-431 or higher as this has specific kernel fixes
|
|
|
+to allow Docker to run.
|
|
|
+
|
|
|
+## Installation
|
|
|
+
|
|
|
+Firstly, you need to ensure you have the EPEL repository enabled. 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 install 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. First we'll need to get the latest
|
|
|
+centos image.
|
|
|
+
|
|
|
+ $ sudo docker pull centos:latest
|
|
|
+
|
|
|
+Next we'll make sure that we can see the image by running:
|
|
|
+
|
|
|
+ $ sudo docker images centos
|
|
|
+
|
|
|
+This should generate some output similar to:
|
|
|
+
|
|
|
+ $ sudo docker images centos
|
|
|
+ REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE
|
|
|
+ centos latest 0b443ba03958 2 hours ago 297.6 MB
|
|
|
+
|
|
|
+Run a simple bash shell to test the image:
|
|
|
+
|
|
|
+ $ sudo docker run -i -t centos /bin/bash
|
|
|
+
|
|
|
+If everything is working properly, you'll get a simple bash prompt. Type exit to continue.
|
|
|
+
|
|
|
+**Done!**
|
|
|
+You can either continue with the [*Hello World*](/examples/hello_world/#hello-world) example,
|
|
|
+or explore and build on the images yourself.
|
|
|
+
|
|
|
+## Issues?
|
|
|
+
|
|
|
+If you have any issues - please report them directly in the
|
|
|
+[CentOS bug tracker](http://bugs.centos.org).
