Overview of this book

This book is focused on setting up and using one of the most important services in OpenStack orchestration, Heat. First, the book introduces you to the orchestration service for OpenStack to help you understand the uses of the templating mechanism, complex control groups of cloud resources, and huge-potential and multiple-use cases. We then move on to the topology and orchestration specification for cloud applications and standards, before introducing the most popular IaaS cloud framework, Heat. You will get to grips with the standards used in Heat, overview and roadmap, architecture and CLI, heat API, heat engine, CloudWatch API, scaling principles, JeOS and installation and configuration of Heat. We wrap up by giving you some insights into troubleshooting for OpenStack. With easy-to-follow, step-by-step instructions and supporting images, you will be able to manage OpenStack operations by implementing the orchestration services of Heat.

Yum update fails with dependency problems related to the oz package

If oz was built from the Git repository, as described in the installation guides, then apt-get update (on Ubuntu) of yum update (CentOS) will fail due to dependency problems while updating the Python packages for OS.

This is because the package (for oz) built locally also needs to be updated to match the Python version. The solution is to remove the package, and then install it again after doing a system update:

sudo yum remove oz
sudo yum update
# rebuild OZ as detailed in the getting started guide
cd ~/git/oz/
git pull
rm -f ~/rpmbuild/RPMS/noarch/oz-*
make rpm
sudo yum localinstall ~/rpmbuild/RPMS/noarch/oz-*.rpm


For Ubuntu, please refer to the installation guide.
