Istio's control plane binary (pilot-discovery) -- Pilot/xDS discovery, the sidecar-injecting webhook, and the mesh CA -- built from source on Wolfi. Ships three minor lines in parallel (1.28/1.29/1.30). Boots against a baked-in, unreachable kubeconfig for the standalone smoke test; a real deployment points it at a live cluster via the chart.

Version

1.30.4 · latest1.29.71.28.10

The latest line lives at the base page; older lines have their own page so you can pin and verify exactly that version.

Current digest (deployed by the chart)

Signatures, the SBOM, and provenance all attach to this digest. Pin to it for reproducible, tamper-evident pulls.

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/istiod:1.30.4 \
  --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/istiod:1.30.4 \
  --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/istiod:1.30.4 \
  --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).
