To integrate Docker with OpenStack, a compute node's driver needs to be changed from libvirt
to docker
. This forces an entire compute node's worth of virtualization capacity to be converted to container capacity. Docker containers and virtual machines cannot coexist on a compute node together. Docker containers and virtual machines can coexist in the same OpenStack cluster as long as there are at least two compute nodes, one for containers and one for virtual machines. For now, you will convert your existing compute node to docker
, then in Chapter 11, Scaling Horizontally, you will attach another compute node to re-enable virtual machine management.

Overview of this book
OpenStack is a widely popular platform for cloud computing. Applications that are built for this platform are resilient to failure and convenient to scale. This book, an update to our extremely popular OpenStack Essentials (published in May 2015) will help you master not only the essential bits, but will also examine the new features of the latest OpenStack release - Mitaka; showcasing how to put them to work straight away.
This book begins with the installation and demonstration of the architecture. This book will tech you the core 8 topics of OpenStack. They are Keystone for Identity Management, Glance for Image management, Neutron for network management, Nova for instance management, Cinder for Block storage, Swift for Object storage, Ceilometer for Telemetry and Heat for Orchestration. Further more you will learn about launching and configuring Docker containers and also about scaling them horizontally. You will also learn about monitoring and Troubleshooting OpenStack.
