Definition
OpenShift is Red Hat's enterprise Kubernetes platform that adds developer and operations tooling, security defaults, and automated lifecycle management on top of upstream Kubernetes for building and running containerized applications.
Overview
OpenShift wraps Kubernetes with an opinionated, enterprise-focused distribution designed to reduce the operational burden of running container platforms at scale. It bundles an integrated container registry, a build system (Source-to-Image) that can turn application source code directly into container images, and a web console alongside the standard Kubernetes API and CLI tooling. A defining characteristic of OpenShift is its security-hardened defaults — most notably restricted Security Context Constraints that prevent containers from running as root by default, which is stricter than plain Kubernetes out of the box. It also layers in the Operator Framework for automating the deployment and lifecycle of complex stateful applications, and integrates tightly with Red Hat's broader ecosystem, including Ansible for automation and Red Hat Enterprise Linux CoreOS as its default node operating system. OpenShift is commonly deployed in regulated industries — finance, healthcare, government — where enterprises want Kubernetes' flexibility combined with vendor support, compliance certifications, and a more curated upgrade path than assembling a cluster from upstream components. It competes with managed offerings like Amazon EKS and self-managed Kubernetes distributions, and is a common topic within broader Kubernetes training.
Key Features

- Source-to-Image (S2I) builds that turn source code into container images
- Security Context Constraints enforcing non-root containers by default
- Operator Framework for automating complex application lifecycle management
- Web console and developer-friendly CLI (oc) alongside standard kubectl
- Tight integration with Red Hat Enterprise Linux CoreOS and Ansible
