Overview of OpenShift installation methods

OpenShift Origin can be installed in several ways, depending on OS and requirements regarding availability, reliability, and scalability.

RPM installation

This is the default method. It installs all required services as systemd units from RPM packages, and they are available on RHEL/CentOS/Fedora. We will focus on this method using the CentOS 7 Linux distribution in the upcoming sections so that you may get a better understanding of the mechanisms involved.

Containerized installation

This is the only available method for Atomic Host OS. It installs OpenShift services in Docker containers, which provides an additional level of control. This method is preferable in an enterprise environment, as Atomic Host makes any dependency issues between packages a thing of the past and makes the host preparation process much easier, as Atomic Host provides a container-focused environment out of the box.
