Managing the Lifecycle of OpenShift Clusters: Vetting OpenShift Installations

Whether installing a new release of a software package or just installing an update (such as a bug fix), it is wise to perform tests against the newly installed software in order to confirm that it is performing correctly in the target environment. This is especially true with OpenShift since it contains a number of open source components and can be deployed to a variety of environments, such as an on-prem datacenter, or a public or private cloud.
