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 before you build on it:

# 1. signature — built and signed by QuenchWorks CI
cosign verify ghcr.io/quenchworks/images/rust:1.94 \
  --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
gh attestation verify oci://ghcr.io/quenchworks/images/rust:1.94 --owner quenchworks

# 3. SPDX SBOM — the package inventory
gh attestation verify oci://ghcr.io/quenchworks/images/rust:1.94 --owner quenchworks \
  --predicate-type https://spdx.dev/Document

See the SBOM & provenance guide for reading the SBOM and using these checks in CI.

Best-practice Dockerfile for 1.94

Compile a release binary against the musl target on the rust image so it links statically, then copy it onto the tiny static base. The Cargo home points at /tmp for the read-only root filesystem.

1
# Build stage: compile a static (musl) release binary.
2
FROM ghcr.io/quenchworks/images/rust:1.94 AS build
3
USER root
4
WORKDIR /src
5
ENV CARGO_HOME=/tmp/cargo
6

7
RUN ["rustup", "target", "add", "x86_64-unknown-linux-musl"]
8
COPY Cargo.toml Cargo.lock ./
9
COPY src ./src
10
RUN ["cargo", "build", "--release", "--target", "x86_64-unknown-linux-musl"]
11

12
# Runtime stage: just the binary on the tiny static base, nonroot.
13
FROM ghcr.io/quenchworks/images/static
14
COPY --from=build /src/target/x86_64-unknown-linux-musl/release/app /app
15
USER 1001
16
EXPOSE 8080
17
ENTRYPOINT ["/app"]

This Dockerfile is pinned to the 1.94 line. For the line-by-line walkthrough and ecosystem variants (npm/Yarn, pip/uv/Poetry, Maven/Gradle), see the Build a Go or Rust binary guide.
