Overview

An enterprise-ready Kubernetes container platform with developer and operational tools.

Key Features

  • Hardened Kubernetes with Security Context Constraints (SCCs) by default
  • Built-in CI/CD via OpenShift Pipelines (Tekton) and OpenShift GitOps (Argo CD)
  • Developer-friendly oc CLI and web console with guided deployment flows
  • Source-to-Image (S2I) builds container images directly from source code
  • OpenShift Service Mesh based on Istio for traffic management and mTLS
  • Available on AWS, Azure, GCP, IBM Cloud, and bare metal

Real-World Workflows

Enterprise Java app deployment with S2I

  1. 1Point an OpenShift build config at a Git repository with Java source code
  2. 2S2I builder detects the language, compiles the code, and creates a container image
  3. 3Image is stored in the OpenShift internal registry and deployed automatically
  4. 4Route is created for external access with TLS terminated at the HAProxy router
  5. 5Rolling deployments triggered on every new image build

Multi-tenant platform for development teams

  1. 1Create a project (namespace) per team with resource quotas and LimitRanges
  2. 2SCCs enforce that no container runs as root without explicit permission
  3. 3OpenShift GitOps (Argo CD) manages application deployment per team namespace
  4. 4Platform team manages shared services (monitoring, logging) in dedicated namespaces
