docker pull ghcr.io/quenchworks/images/composer:2.10.1

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/composer:2.10.1 \
  --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/composer:2.10.1 \
  --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/composer:2.10.1 \
  --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 2.10.1

Composer leads: it installs and locks the production dependency set in the build stage, then a clean php base receives the vendor tree and the app. Composer itself never ships.

1
# Build stage: Composer installs and locks prod dependencies.
2
FROM ghcr.io/quenchworks/images/composer:2.10.1 AS build
3
USER root
4
WORKDIR /app
5
ENV COMPOSER_CACHE_DIR=/tmp/composer
6

7
COPY composer.json composer.lock ./
8
RUN ["composer", "install", "--no-dev", "--no-scripts", "--prefer-dist", "--no-progress"]
9
COPY . .
10
RUN ["composer", "dump-autoload", "--optimize", "--no-dev"]
11

12
# Runtime stage: vendor + app on a slim php base, nonroot.
13
FROM ghcr.io/quenchworks/images/php:8.5.9 AS runtime
14
WORKDIR /app
15
COPY --from=build /app /app
16
USER 1001
17
EXPOSE 8080
18
CMD ["php", "-S", "0.0.0.0:8080", "-t", "public"]
