Each tag is a multi-arch index (amd64 + arm64) pinned by digest. Tagged by version, never :latest.

Use it as a base image

Reference it in the FROM line of your Dockerfile. Nonroot, read-only root filesystem, built for amd64 and arm64.

FROM ghcr.io/quenchworks/images/dotnet:10.0.110

Or pull it directly

docker pull ghcr.io/quenchworks/images/dotnet:10.0.110

Version line

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

# 1. signature — built and signed by QuenchWorks CI
cosign verify ghcr.io/quenchworks/images/dotnet:10.0.110 \
  --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/dotnet:10.0.110 \
  --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/dotnet:10.0.110 \
  --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.

Best-practice Dockerfile for 10.0.110
