We would like to announce the availability of CentOS Linux docker images, via the docker index.

==========Information

To use these images, you will need to first install and start the docker service. Documentation about this may be found at http://wiki.CentOS.org/Cloud/Docker or https://docs.docker.com/installation/CentOS/

The kickstarts used to build these images are located at https://github.com/CentOS/sig-cloud-instance-build.

=======Download

Once docker is running, you can download the images using the command:

docker pull CentOS

Once docker is finished fetching the images, you can verify them by using the command:

docker images

This command should display output similar to:

[jperrin@lappy ~]$ docker images REPOSITORY TAG IMAGE ID CREATED
VIRTUAL SIZE
CentOS CentOS7 1a7dc42f78ba 5 hours ago 236.4 MB
CentOS latest 1a7dc42f78ba 5 hours ago 236.4 MB
CentOS CentOS6 cd934e0010d5 17 hours ago 206.9 MB

====Usage

running the default ‘CentOS’ image will use the latest release, CentOS-7.

[jperrin@lappy ~]$ docker run -i -t CentOS /bin/cat /etc/CentOS-release CentOS Linux release 7.0.1406 (Core)

To use the CentOS-6 image, you must specify the tag in the command:

[jperrin@lappy ~]$ docker run -i -t CentOS:CentOS6 /bin/cat
/etc/CentOS-release CentOS release 6.5 (Final)

====Thanks

We would like to thank Chris StPierre for his initial work with docker, and developing the kickstarts used for the build process.
