Dockerfile - Upgrade bundled Docker to 29.7.2 in cuda13.0

[gusui-msft]

Description

The bundled Docker static distribution is pinned at 20.10.8, which was built with Go 1.16.6. A Trivy 0.72.0 scan of superbench.azurecr.io/internal/hpc:main-cuda13.0 (2026-07-15) reports 40 Critical occurrences against the eight binaries this Dockerfile unpacks into /usr/local/bin/. That is 69% of the 58 Critical findings in the image, and the largest single source of Critical findings we own.

These are compiled-in Go dependencies, not installed packages, so they cannot be fixed with apt or pip. The bundle itself has to be replaced.

Docker 29.7.2 (released 2026-08-05) is built with Go 1.26.5 and carries gRPC v1.82.1, which clears every CVE reported against this bundle:

CVE	Component	Occurrences	Required fix	29.7.2 ships
CVE-2025-68121	Go stdlib	8	1.24.13, 1.25.7, 1.26.0-rc.3	go1.26.5
CVE-2022-23806	Go stdlib	8	1.16.14, 1.17.7	go1.26.5
CVE-2023-24538	Go stdlib	8	1.19.8, 1.20.3	go1.26.5
CVE-2023-24540	Go stdlib	8	1.19.9, 1.20.4	go1.26.5
CVE-2024-24790	Go stdlib	8	1.21.11, 1.22.4	go1.26.5

Major Revision

• Bump DOCKER_VERSION from 20.10.8 to 29.7.2 in dockerfile/cuda13.0.dockerfile.

Minor Revision

• Update the Docker line in the version comment header to the new version, and correct it to say the full static bundle is installed rather than only the client.

Verification done before opening

Both architecture tarballs were downloaded from download.docker.com/linux/static/stable/ and inspected:

• x86_64/docker-29.7.2.tgz and aarch64/docker-29.7.2.tgz both return 200. ${TARGETARCH_HW} already resolves correctly for both.
• Every binary in the bundle reports go1.26.5, on both architectures.
• dockerd embeds google.golang.org/grpc v1.82.1.
• The extracted client is statically linked and reports Docker version 29.7.2, build a7dcaa6.

Host compatibility

SuperBench only uses the Docker client against the host daemon socket (monitor.py, docker_base.py, runner.py, system_info.py, and deploy.yaml, which mounts /var/run/docker.sock). There is no reference to dockerd, containerd, runc, ctr, or docker-proxy anywhere in the tree.

Docker 29.3.0 lowered the minimum daemon API version from v1.44 back to v1.40 (Docker 19.03), so the newer client still talks to older host daemons. docker login --username/--password and every subcommand we invoke are still present in 29.7.2.

One behavioural note for reviewers: the v1 containerd-shim binary no longer ships in the 29.x bundle. Nothing in this repository references it.

Draft, pending

• cuda13.0 image builds on arm64 and amd64
• docker --version inside the built image reports 29.7.2
• Rescan the pushed digest per architecture and confirm the 40 occurrences are gone, and that 29.7.2 introduces no new findings from its other Go modules

Not in this PR

• The same bump for rocm6.3.x.dockerfile (Docker 27.5.1, 8 Critical), which is a separate PR because it is a different vendor image, different runner, and different reviewers.
• cuda12.9 and cuda11.1.1 are also built by CI and still carry 20.10.8. They were not scanned, but they install the same bundle. Happy to extend this PR to them if reviewers prefer.
• Installing only the docker client instead of the full bundle. That would drop 7 unused binaries and ~181 MB, but it changes image contents rather than a version string, so it is left as a follow-up.
• Checksum verification of the downloaded tarball. Worth doing, but it is the same gap in every dockerfile/*.dockerfile here, so it belongs in one change across all of them rather than only this one.
• The base-image-inherited findings (linux-libc-dev, jupyter_server, Nsight), which are handled by a CUDA 13.3 base upgrade.

Pull request overview

Updates the CUDA 13.0 container image definition to use a newer Docker static distribution, aiming to remove critical CVEs stemming from compiled-in Go dependencies in the bundled Docker binaries.

Changes:

• Bump the pinned Docker static bundle version from 20.10.8 to 29.7.2.
• Update the Docker version noted in the Dockerfile header comment to match the new pinned version.

Suppressed comments (1)

dockerfile/cuda13.0.dockerfile:74

• The Docker tarball is downloaded and extracted without any integrity verification. Since this PR is motivated by supply-chain CVEs, it would be safer to also verify the downloaded artifact against Docker’s published SHA256 before extracting it.

ENV DOCKER_VERSION=29.7.2
RUN TARGETARCH_HW=$(uname -m) && \
    wget -q https://download.docker.com/linux/static/stable/${TARGETARCH_HW}/docker-${DOCKER_VERSION}.tgz -O docker.tgz && \
    tar --extract --file docker.tgz --strip-components 1 --directory /usr/local/bin/ && \
    rm docker.tgz
