The OpenShift Serverless Logic Operator is currently certified and released exclusively for OpenShift. However, customers are requesting support and certification for other Kubernetes distributions, specifically:

• Azure Kubernetes Service (AKS)
• Amazon Elastic Kubernetes Service (EKS)
• Google Kubernetes Engine (GKE)

The upstream project already targets non-OpenShift environments (Minikube, KIND) during CI. This umbrella issue tracks the overall evaluation effort and guides the work that will be done in phases across these platforms.

Behavioral Differences

• Service Exposure
  • On OpenShift, the Operator uses Route resources to expose platform services (OpenShift-specific).
  • On Kubernetes, users must manually expose services (e.g., using Ingress, LoadBalancer, etc.).
  • The Operator should:
    • Log a message prompting users to expose services manually, or
    • Provide examples using common ingress options (nginx, Traefik, etc.)

• Preview Workflow Builds
  • In preview mode, OpenShift uses BuildConfig and ImageStreams
  • On Kubernetes, builds are attempted with Kaniko, which may introduce compatibility/security issues
  • Proposal:
    • Disable support for preview profile in non-OpenShift environments
    • Clearly document this limitation

• Installation Procedure
  • Users must currently rely on OperatorHub or manual installation
  • Future options may include the Orchestrator Operator (TBD)
  • Helm charts or raw manifests are currently alternatives from the Orchestrator Operator pov.

Acceptance Criteria

• [ ] Document all behavioral differences between OpenShift and Kubernetes
• [ ] Provide recommendations for:
  • Exposing services
  • Disabling preview mode
• [ ] Create reproducible installation/test instructions for:
  • Minikube
  • KIND
• [ ] Track installation, evaluation, and certification progress for:
  • AKS — See sub-task JIRA: SRVLOGIC-565
  • EKS — See sub-task JIRA: SRVLOGIC-566
  • GKE — See sub-task JIRA: SRVLOGIC-567
• [ ] Update official documentation accordingly
• [ ] Ensure the Operator gracefully avoids OpenShift-specific resources in Kubernetes

Notes

• Supported platforms for Red Hat Developer Hub (RHDH): https://access.redhat.com/support/policy/updates/developerhub
• OpenShift Serverless Logic is expected to align with the same platform support roadmap
