Fix: upgrade gateway-api to v1.6.0 - #76
Conversation
📝 WalkthroughWalkthroughGateway API dependencies and policy machinery now use Gateway API v1. Policy target references, interfaces, examples, reconcilers, documentation, and tests migrate from v1alpha2. BackendLBPolicy support is removed. ChangesGateway API compatibility
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The gateway API upgrade currently does not persist target-reference normalization, which can cause incorrect locator behavior. Merge should wait for this correctness fix; the examples toolchain version also needs owner follow-up. Poem

- Bumps
sigs.k8s.io/gateway-apiand related Kubernetes/controller-runtime/OpenTelemetry dependencies. - Refactors policy target reference wrappers and tests to use Gateway API
apis/v1types. - Removes kuadrant-operator references from
examples/kuadrant/apis/v1and introduces local helper interfaces/utilities.

- The
godirective typically uses a supported Go language version (commonly1.xxor1.xx.0depending on tooling). If1.26.4is not intentional and not supported by the toolchain used in CI, it can break module parsing/builds. Please align this to the project’s actual supported Go version (and, if you need a specific toolchain, prefer using thetoolchaindirective).

Copilot may have a point here. This depends on the version of Envoy Gateway API.
Have you tried running cd examples/kuadrant && go build -o kuadrant-example-controller?

It was fixed by bumping github.com/envoyproxy/gateway from v1.3.0 to v1.8.3.

I guess the types were redefined because of now being ahead of github.com/kuadrant/kuadrant-operator wrt Gateway API version, right? That's OK then.

Overall the PR LGTM. Just one minor comment in the Kuadrant policy controller example and it should be fine.

@guicassolato somehow even with different versions of the types, the example was actually getting compiled correctly, therefore couldnt flag it, updated the types now. ptal whenever you get time |

Align the examples toolchain with the supported Go patch release.
If the project remains on Go 1.26, update this directive to at least go 1.26.7. The examples CI jobs currently select Go from the root go.mod (1.26.4) before running tests in ./examples; set those jobs to use examples/go.mod.

Make SetGroupVersionKind mutate the target reference.
The three methods use value receivers, so calls through PolicyTargetReference update only a copy. Use pointer receivers and return pointers from all target-reference producers, including their compile-time assertions. Otherwise, normalisation before GetLocator does not persist.
