Caching forward proxy for HTTP and HTTPS (CONNECT). Pods reach the outside through it, and it caches repeat fetches in memory. The default config allows RFC 1918 and CGN sources and refuses CONNECT to anything but port 443. The chart supplies the config.

Current digest (deployed by the chart)

sha256:6cc7f23e56b076b4cff8340983ca0d35fdcbf5ca02952521f1f0289a61486913

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/squid:7.6 \
  --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/squid:7.6 \
  --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/squid:7.6 \
  --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).
