docker-openstack

Run OpenStack Havana in a Docker container. Includes Keystone, Nova Controller, Glance, Dashboard, MySQL, Apache, and RabbitMQ

Nova-Compute is setup for provisioning Docker images only. Details here http://docs.openstack.org/trunk/config-reference/content/docker.html

Prepare Vagrant

If you're using the offical Docker Vagrantfile to run Docker then you must export FORWARD_DOCKER_PORTS=1 to forward all ports in the 49xxx range.

Start OpenStack container

After building the image using the build script, use shell script to launch OpenStack inside Docker.

Start OpenStack Services

Run supervisord& to start all OpenStack Services.

Docker in Docker

You now have Docker running inside Docker.
The docker ps command will show that the Docker Registry is running in a container too. Run the install-ubuntu-image.sh script to pull the ubuntu image into your local Registry.

Using Horizon

1. Point your browser to http://localhost:49802/horizon
2. You will now be able to launch Docker containers inside OpenStack!

Heat

Heat has been configured with the additional Docker plugin as described here. https://github.com/dotcloud/openstack-heat-docker

That means Heat can create stacks directly with Docker instead of Nova. I'm still getting some errors with the wordpress example.

Special thanks to Jérôme Petazzoni for helping me with a previous DNS/Networking problem. Find out more from his blog entry here http://jpetazzo.github.io/2013/10/16/configure-docker-bridge-network/

Missing license

@mingfang We would like to update this and use it with current OpenStack releases and also begin doing nightly builds/tests to make sure that it continues to build and fix issues as they arise. Can you clarify the license of this project (typically with a LICENSE or LICENSE.txt). If you have a preferred open source license I can create a pull request for you. Seems like MIT is a popular one for sharing Dockerfiles and their associated resources. Thanks!
