kind: Route
metadata:
  name: frontend
spec:
  host: app.example.com
  to:
    kind: Service
    name: frontend
  tls:
    termination: edge
    insecureEdgeTerminationPolicy: Redirect

This allows for advanced traffic management, TLS termination, and simplified hostname-based routing.

OpenShift’s BuildConfig resource automates the application build process:

apiVersion: build.openshift.io/v1
kind: BuildConfig

  strategy:
    sourceStrategy:
      from:
        kind: ImageStreamTag
        name: nodejs:14
  output:
    to:
      kind: ImageStreamTag
      name: frontend:latest
  triggers:
    - type: GitHub
      github:
        secret: secret101

This seamless integration with source code repositories enables automated builds directly from code changes.

OpenShift enhances Kubernetes namespaces with the Project concept, adding additional capabilities for multi-tenancy, resource quotas, and access control:

# Create a new project with resource limits
oc new-project team-alpha \
  --description="Alpha Team Development Environment" \
  --display-name="Alpha Team"

oc create quota team-quota \
  --project=team-alpha \
  --hard=cpu=10,memory=20Gi,pods=25

This enables organizations to implement robust multi-tenancy within a single cluster.

OpenShift implements a security-first approach:

• Security Context Constraints (SCCs): More granular control than Kubernetes Pod Security Policies
• RBAC integration: Comprehensive role-based access control
• Certificate management: Automated TLS certificate provisioning and rotation
