Tag: OpenShift Cheat Sheet
OpenShift Cheat Sheet includes basic commands to help you using OpenShift. OpenShift is a family of containerization software developed by Red Hat. Its flagship product is the OpenShift Container Platform—an on-premises platform as a service built around Docker containers orchestrated and managed by Kubernetes on a foundation of Red Hat Enterprise Linux. The family’s other products provide this platform through different environments: OKD serves as the community-driven upstream (akin to Fedora), OpenShift Online is the platform offered as software as a service, and Openshift Dedicated is the platform offered as a managed service.
