Putting the pipeline together

Now that we've described the different components of the deployment pipeline, let's assemble an example pipeline in our lab environment. We'll start by setting up the CI server, creating a new composition layer, writing a unit test, and then deploying the OpenStack infrastructure to pass the test.

Setting up the CI server

In previous chapters, we deployed OpenStack by running the packstack utility from the cloud controller. In this section, we'll be setting up a dedicated machine to do our deployments. The requirements for our deployment machine are not too strenuous - any machine running CentOS 7 with 2 GB of RAM or more should suffice. The only network requirements are that the machine is reachable from both the intranet and from the OpenStack cluster itself.

Installing Git

The following instructions will set up a Git version control server on the CI server. If you already have access to a Git repository or prefer to use GitHub you can skip this section. For more...
