kgateway, the CNCF Gateway API control plane that succeeded Gloo Edge. Watches Gateway, HTTPRoute, GRPCRoute and its own gateway.kgateway.dev policy CRDs, programs Envoy over xDS and provisions the proxy fleet itself. Pairs with the QuenchWorks kgateway-envoy data plane. Ships two minor lines because 2.2.x pins its amd64 data plane to a vendor fork of Envoy this catalog does not rebuild. Carries the Wolfi envoy binary for the strict xDS validation path.

Verify the supply chain

This image is cosign-signed and carries an SPDX SBOM and a SLSA build-provenance attestation on the same digest. Check all three yourself:

# 1. signature — built and signed by QuenchWorks CI
cosign verify ghcr.io/quenchworks/images/kgateway:2.4.3 \
  --certificate-identity-regexp 'https://github.com/quenchworks/.+' \
  --certificate-oidc-issuer https://token.actions.githubusercontent.com

# 2. SLSA build provenance — which workflow built it, from what
cosign verify-attestation --type https://slsa.dev/provenance/v1 ghcr.io/quenchworks/images/kgateway:2.4.3 \
  --certificate-identity-regexp 'https://github.com/quenchworks/.+' \
  --certificate-oidc-issuer https://token.actions.githubusercontent.com

# 3. SPDX SBOM — the package inventory
cosign verify-attestation --type https://spdx.dev/Document/v2.3 ghcr.io/quenchworks/images/kgateway:2.4.3 \
  --certificate-identity-regexp 'https://github.com/quenchworks/.+' \
  --certificate-oidc-issuer https://token.actions.githubusercontent.com

See the SBOM & provenance guide for reading the SBOM and using these checks in CI.

Transparency

Every image carries its SBOM and provenance as attestations on the same digest, publicly verifiable with the commands above (they check the package and the Sigstore transparency log, Rekor).
