build: refresh bundled runtime-image dependencies over the base copies#14082dagil-nvidia wants to merge 5 commits into
Conversation
Floor cryptography (vllm, trtllm) and refresh the bundled diffusers and mooncake-transfer-engine wheels (sglang, vllm) through the existing force-reinstall/no-deps requirement installs, so the system-site copies the images actually ship move to current release lines. Drop the uv cache the upstream vllm-openai base bakes at /opt/uv/cache: its archived wheel copies duplicate installed packages and keep stale versions on disk after the floors refresh them.

- Floor mooncake-transfer-engine-cuda13 rather than the generic project in the vLLM and SGLang requirements. Both bases install the CUDA 13 distribution, and the generic wheel links libcudart.so.12 while shipping the same `mooncake` package, so flooring the generic name overlays the CUDA 13 build with an unloadable one instead of upgrading it. - Strip that floor for the non-CUDA vLLM and SGLang images, which carry no mooncake at all, and assert the distribution is absent so a filter that stops matching fails the build rather than looking like success. - Drop the diffusers floor. It overrode SGLang's exact diffusers==0.37.0 pin for a path Dynamo does not import, and landed a minor behind the copy the TensorRT-LLM runtime base already ships.

Late pass on this one, so purely FYI against the two approvals — nothing here is a merge blocker except possibly the first.
For the record on the parts I checked and found correct: the rm -rf /opt/uv/cache is well-founded. I verified the published vllm/vllm-openai:v0.27.1-ubuntu2404 (amd64) directly — its top layer (sha256:5afb1ce2…, 482 MB) is the ARG MOONCAKE_WHEEL_* RUN, the one uv invocation in vllm-openai-base with no --mount=type=cache, and it bakes opt/uv/cache/archive-v0/…/mooncake/libetcd_wrapper.so into the image — a duplicate of exactly the file DYN-4121 tracks. .buildkite/release-pipeline.yaml passes MOONCAKE_WHEEL_X86_64 + INSTALL_KV_CONNECTORS=true, so it always fires. Dropping the cache in that layer is the right fix, and a whiteout is sufficient because the scan reads the merged filesystem.

Three things in this one-liner.
1. d.metadata can be None. importlib.metadata.Distribution.metadata returns None — not an empty message — when a distribution's METADATA/PKG-INFO can't be read, so d.metadata['Name'] raises TypeError: 'NoneType' object is not subscriptable. The or '' only guards a missing Name header, not missing metadata. Not hypothetical here: the codec purge a few lines below removes *.dist-info directories by glob, so any partially-removed or vendored .dist-info left by a base bump produces exactly that state — and the RUN then exits with a traceback that says nothing about the mooncake filter it was verifying.
2. The normalization isn't PEP 503. Canonical is re.sub(r"[-_.]+", "-", name).lower(); .replace('_','-').lower() misses . and repeated separators. A Name using either wouldn't match the literal, so the check would report "absent" for a package that is installed — reintroducing the "a filter that silently stopped matching would look like success" failure this line exists to prevent.
Both go away with Distribution.name (3.10+), which returns the already-canonicalized value:
names = {(d.name or '').lower() for d in m.distributions()}3. It's duplicated. This is byte-identical to vllm_runtime.Dockerfile:429 apart from python3 vs /opt/venv/bin/python, so each of the above needs fixing twice, in a one-liner that can't be linted, unit-tested, or read in a diff. container/compliance/ already holds helpers of exactly this shape (enumerate_bundled_decoders.py), and both templates already know how to bind-mount one into a RUN. A container/compliance/assert_distribution_absent.py <name> would be one copy, testable, and would print a real error instead of a bare exit code.

Worth calling out in the PR description: this branch also drops PyNvVideoCodec>=2.2.0 (requirements.sglang.txt:28) from the SGLang XPU image, which installed it before this PR since the RUN was unconditional.
The reasoning in the comment is sound and it matches what vllm_runtime.Dockerfile already does for XPU/CPU, so no objection to the change itself. But the title, body and both commit messages only mention cryptography/diffusers/mooncake, so it's easy to approve "refresh bundled runtime-image dependencies" without noticing an NVDEC wheel left an image.
It also makes the comment at components/src/dynamo/common/utils/install_media_decoders.py:122-125 — "PyNvVideoCodec — already shipped in every runtime image as the NVDEC path, so H.264/H.265 decode needs no install" — false for one more image, and that comment is the stated reason PyNvVideoCodec is excluded from _BACKEND_DECODERS.

Declined code change. The behavior is correct and intentional. Reworded the stale claim in a02f042: install_media_decoders.py and additional-media-decoders.md now say PyNvVideoCodec ships in every CUDA runtime image, not every runtime image. PR description staleness is unchanged; that needs a human edit.
There was a problem hiding this comment.
The code comment and the docs page are both correctly scoped now — PyNvVideoCodec does ship in all three CUDA runtime images (trtllm rc25 carries 2.1.0 per its SBOM and trtllm_runtime.Dockerfile raises it; sglang and vllm floor >=2.2.0 on the CUDA branch), so "every CUDA runtime image" is accurate.
Leaving this open for the description half only, which has grown since — details in the review body.
Drop the trtllm cryptography floor: the pinned 1.3.0rc24 base already ships cryptography 50.0.0 per its checked-in SBOM, and the file installs into the venv without --system, so it never reaches the compliance-scanned location anyway. Bound the mooncake-transfer-engine-cuda13 floors to <0.4, matching the file's existing convention for base-pinned packages with compiled extensions. Guard the hardcoded -cuda13 distribution name with a CUDA_MAJOR build-time assertion so a future non-CUDA-13 image fails the build instead of silently overlaying the wrong wheel. Fix the mooncake absence check to handle distributions with no readable metadata and to normalize names per PEP 503. Make the PyNvVideoCodec absence check on the SGLang XPU image a positive test instead of an invertible negative one, and stop leaking the filtered requirements file into the image layer.

The mooncake-absence check filtered on a metadata field that is never None, so the AttributeError guard it was meant to add never landed; bind and filter on the Name value instead, and use sys.exit in both Dockerfiles for interpreters invoked with -S. Extend the uv cache cleanup to the XPU and CPU branches, since the floors it protects apply there too, and reword the comment to describe what the removal actually does for compliance scanners. Guard the SGLang template's CUDA_MAJOR ARG behind the cuda device check to match vLLM, and correct the PyNvVideoCodec pre-installed claim to scope it to CUDA runtime images.

Round 2. Six of my seven comments are fixed and I've verified each rather than taking the replies at face value — details in the threads. One correction to myself first: I was wrong that Distribution.metadata can be None. It returns an empty, falsy Message; the is not None guard in 8775405 was inert, exactly as a02f042 says. I measured all three forms against a broken .dist-info and the final one is correct.
Three things left, none of them a correctness bug in the shipped CUDA images:
vllm_runtime.Dockerfile:403— the uv cache is not baked in the pinned base. I listed every layer ofv0.28.0-ubuntu2404on both arches: zero/opt/uv/entries in all 30. The 482 MB cache layer was real on v0.27.1, but v0.28.0 changed the mooncake install and it's gone. Thermis harmless; the comment justifying it states a stale fact as present tense, and a02f042 extended it to two more bases that never had one.sglang_runtime.Dockerfile:200— no CI builds the XPU branch. There is no SGLang XPU job anywhere in.github/workflows/, andxpu-ci-vllmisxpu-label-gated and skipped here. The entire new{% else %}branch, and both a02f042 fixes, are unexecuted.vllm_runtime.Dockerfile:432— one of the two!-inverted checks was left behind. One-line change, matches the sibling you just fixed.
Verified along the way, so they don't need re-checking: mooncake-transfer-engine-cuda13 0.3.13.post1 is the current release with cp312 manylinux_2_28 wheels on both arches; the vLLM base ships 0.3.12.post1 and SGLang v0.5.18 pins the same, so both floors are real upgrades; trtllm rc25's SBOM has cryptography 50.0.1, so dropping that floor is safe against the tag now pinned, not just rc24; and ARG CUDA_MAJOR resolves in the right stage in both templates with the &&/|| chain shaped correctly.
One more thing, on the description. I raised this last round and you said it needs a human edit — it has since gotten worse, and it's the artifact reviewers approve against:
- The trtllm bullet describes a change that no longer exists;
requirements.trtllm.txtisn't in the diff at all. - The sglang bullet still promises the
diffusers0.38 refresh, dropped back in 5a1b637. - Unmentioned: PyNvVideoCodec leaving the SGLang XPU image, the
CUDA_MAJORassertion, and the two files this PR now touches outsidecontainer/(install_media_decoders.py,additional-media-decoders.md). - "Image builds validate in CI" is true for CUDA and false for XPU/CPU, per (2).
- No Related Issues section — this is DYN-4027 / DYN-4121 work and neither is linked.
Nothing here blocks the CUDA images, which are the ones with real CI behind them.

vllm/vllm-openai:v0.28.0-ubuntu2404 does not bake a uv cache. I audited every layer of the pinned tag, on both arches:
amd64: 15 non-trivial layers, `tar -t | grep -c '^opt/uv/'` == 0 for all 15
arm64: 15 non-trivial layers, same, 0 for all 15
The only /opt/uv content in the whole image is layer 10, 150 bytes:
drwxrwxr-x opt/uv/
drwxrwxr-x opt/uv/cache/
drwxrwxr-x opt/uv/python/
three empty directories from mkdir -p "${UV_PYTHON_INSTALL_DIR}" "${UV_CACHE_DIR}" && chgrp -R 0 /opt/uv && chmod -R g+rwX,a+rX /opt/uv. ENV UV_CACHE_DIR=/opt/uv/cache is still set in the image config, but every uv RUN upstream now mounts a cache over it.
The baked cache was real on v0.27.1-ubuntu2404: mooncake there was installed from an ARG MOONCAKE_WHEEL_* RUN, the one uv invocation without --mount=type=cache, and its 482 MB layer held opt/uv/cache/archive-v0/.../mooncake/libetcd_wrapper.so. v0.28.0 replaced that mechanism entirely — layer 31 (INSTALL_KV_CONNECTORS=true) now runs
uv pip uninstall --system mooncake-transfer-engine;
uv pip install --system "mooncake-transfer-engine-cuda13==${MOONCAKE_VERSION}"and that layer has no /opt/uv content at all.
container/context.yaml has pinned v0.28.0-ubuntu2404 since before this branch — it is already the value at 810131af^ — so this rm has never had anything to delete on this PR.
The rm itself is harmless. The six-line comment above it is the part I would change: it asserts as present-tense fact something a future reader will not re-verify, and it is the item the PR description leads with. Either drop both, or keep the rm and say what it is — defensive against a base that used to bake the cache and could again.
Same for extending it to the XPU and CPU branches in a02f042 (line 434). Those bases are vllm/vllm-openai-xpu:v0.27.1 and vllm/vllm-openai-cpu:v0.28.0, not vllm/vllm-openai, and the checked-in self-baseline for XPU (container/compliance/base_sboms/vllm-openai-xpu@3309c2e1-amd64.cdx.json) records 831 components under /opt and zero under /opt/uv.
Unrelated but from the same listing, and good news for the floor: that layer 31 contains usr/local/lib/python3.12/dist-packages/mooncake_transfer_engine_cuda13-0.3.12.post1.dist-info/, so >=0.3.13.post1,<0.4 is a genuine upgrade against the tag being built.

Nothing builds this branch — not pre-merge, not post-merge, not nightly.
grep -rn 'sglang.*xpu' .github/workflows/ returns nothing. pr-xpu.yaml defines exactly one job, xpu-ci-vllm (framework: vllm), gated on the xpu label at pr-xpu.yaml:23-47; this PR's labels are documentation, size/M, backend::vllm, build, container, so it shows skipping. post-merge-ci.yml:661 and nightly-ci.yml:1079 both define vllm-xpu only. And --device cpu appears in no workflow, so the vLLM CPU branch is unbuilt too.
So this whole {% else %}, new in this PR, has never been executed — and both a02f042 corrections land only in non-CUDA branches: the walrus form of the mooncake check, and rm -rf /opt/uv/cache. The CUDA side is genuinely well covered by contrast (sglang-runtime / Test cuda13.0, amd64 passed 41m53s this round, so the CUDA_MAJOR assertion and both floors are proven there).
I verified what I could statically — rendered all five affected variants, the branch is well-formed, find_spec is the right call, and the mooncake one-liner normalizes and tolerates a nameless .dist-info (measured, see the thread above). But static review is not a build.
Concretely: adding the xpu label would run xpu-ci-vllm, which exercises the shared vLLM non-CUDA RUN — same filter shape, same one-liner, same rm -rf. The SGLang XPU branch would still be build-unverified, which is worth stating in the PR rather than leaving "Image builds validate in CI" to cover it.

This one still can't fail, and the comment eight lines up now claims otherwise.
import PyNvVideoCodec dlopens libnvcuvid.so.1. The XPU and CPU builders have no NVIDIA driver, so the import raises whether or not the wheel is installed, and ! turns that into success. If the grep -v filter ever stopped matching, PyNvVideoCodec would ship in the XPU image and this line would still pass — which is precisely the failure the comment says it prevents ("the import check fails the build if the package arrives by another route -- a filter that silently stopped matching would otherwise look like success").
The line is pre-existing and I said so last round. What makes it in scope now is that this PR rewrote its chain and fixed the identical shape in the new SGLang branch, so one of the two copies is left behind while the comments still read as parallel. Same one-liner as sglang_runtime.Dockerfile:208:
/opt/venv/bin/python -c "import importlib.util,sys; sys.exit(1 if importlib.util.find_spec('PyNvVideoCodec') else 0)" && \
(Incidentally, the vacuous-pass hole I flagged for SGLang is closed here as a side effect: the mooncake check now follows in the same && chain, so a genuinely broken interpreter fails at the next command. It's only the driverless-builder case that survives.)

Refresh the copies of four third-party packages that the runtime images actually ship, through the requirement files each image already installs over its base with
--no-deps/--force-reinstall:diffusersto the current 0.38 line (the upstream image pins the prior minor via its diffusion extra) and the bundledmooncake-transfer-enginewheel, whose older builds vendor a stale Go dependency set insidelibetcd_wrapper.so.cryptographyto the current release line and refreshmooncake-transfer-engine(same rationale). Drop the uv cache the upstream vllm-openai base bakes at/opt/uv/cache- its archived wheel copies duplicate installed packages and keep stale versions on disk after the floors refresh them.cryptographyalongside the existing floors (same mechanism as build: apply trtllm image floors to the system-site install #13256).Why
These are the packages where the shipped copy comes from the base image rather than our dependency set, so ordinary version floors in our own layers never reach them. The refreshed lines carry current upstream maintenance releases; the v1.5.0 QA cycle runs the full regression suite, which covers the touched surfaces (SGLang diffusion pipelines, TLS paths, KV transfer).
