Ansible installation
Ansible is a configuration management and orchestration tool that's written in Python. OpenShift Origin installer is actually a collection of Ansible playbooks in YAML format that define what services must be installed and how they are to be configured.
Ansible playbooks are run from a single point, which is called a control machine in Ansible terminology. It can be any machine and in our demonstration of advanced installation, we will use the master as a control machine.
These packages are provided by the EPEL repository, which is already enabled out-of-the-box in our lab. If they weren't, you would have to install the epel-release package.
Next, clone the installation playbooks themselves from the Git repository:
