    Description

      Epic Goal

      • Add Gateway API via Istio Gateway implementation as Tech Preview in 4.x

      Problem: ** As an administrator, I would like to securely expose cluster resources to remote clients and services while providing a self-service experience to application developers. 

      Tech Preview:  A feature is implemented as Tech Preview so that developers can issue an update to the Dev Preview MVP and:

      • can still change APIs that are clearly indicated as tech preview, without following a deprecating or backwards compatibility process.
      • are not required to fix bugs customers uncover in your TP feature.
      • do not have to provide an upgrade path from a customer using your TP feature to the GA version of your feature.
      • TBD - must still support upgrading the cluster and your component, but it’s ok if the TP feature doesn’t work after the upgrade.
      • still need to provide docs (which should make it clear the feature is tech preview)
      • still need to provide education to CEE about the feature (tech enablement)
      • must also follow Red Hat's support policy for tech preview
        From https://github.com/openshift/enhancements/blob/master/guidelines/techpreview.md

      Why is this important?

      • Reduces the burden on Red Hat developers to maintain IngressController and Route custom resources
      • Brings OpenShift ingress configuration more in line with standard Kubernetes APIs
      • Demonstrates Red Hat’s leadership in the Kubernetes community.

      Acceptance Criteria (draft)

      • Gateway API and Istio Gateway are in an acceptable standing for Tech Preview
      • Now that we've decided on single control plane (shared between OSSM and Network Edge functionality), complete the feature in collaboration with OSSM
      • Decide on whether we can make an existing OSSM control plane work when the GWAPI feature is enabled on the cluster
      • Decide if the cluster admin can/should configure SMCP, what options are exposed, and API for configuration
      • Document limitations and collect information to plan future work needed to accommodate HyperShift architecture - in OSSM and elsewhere
      • Initial security model
      • Enhancement Proposals, Migration details, Tech Enablement, and other input for QA and Docs as needed
      • Web console
      • Must-gather updates
      • CI, E2E tests on GA OSSM
      • Metrics/Telemetry as needed
      • Installation, Upgrade details (keep OSSM and c-i-o in sync)
      • [stretch] oc updates

      Dependencies (internal and external)

      1. OSSM release schedule aligned with OpenShift's cadence, or workaround designed
