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/go:1.26.5

Or pull it directly

docker pull ghcr.io/quenchworks/images/go:1.26.5

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/go:1.26.5 \
  --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/go:1.26.5 \
  --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/go:1.26.5 \
  --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 1.26.5

The classic two-stage Go build: compile a fully static binary with CGO disabled on the go image, then copy that one file onto the tiny static base. No toolchain, no shell, no package manager in the final image.

1
# Build stage: compile a fully static binary.
2
FROM ghcr.io/quenchworks/images/go:1.26.5 AS build
3
USER root
4
WORKDIR /src
5
# CGO off makes the binary static; caches go to /tmp for the read-only rootfs.
6
ENV CGO_ENABLED=0 \
7
    GOOS=linux \
8
    GOCACHE=/tmp/gocache \
9
    GOMODCACHE=/tmp/gomodcache
