Enable building MoRI with AMD AINIC stack by ichbinblau · Pull Request #38371 · vllm-project/vllm

ichbinblau · 2026-03-27T15:05:56Z

Summary

Updates the ROCm image build (docker/Dockerfile.rocm and docker/Dockerfile.rocm_base) so MORI can be built with an optional AMD AINIC (Pensando / ionic) or **BNXT (broadcom)" NIC stack, following the same approach as SGLang’s docker/rocm.Dockerfile MORI section.

Also bumps the default MORI git pin to v1.1.0, adds MoriIO proxy Python dependencies (blinker, quart, aiohttp, msgpack, pyzmq), and records NIC backend / AINIC version in /app/versions.txt.

Co-authored with: @billishyahao

Motivation

Upgrade MoRI to v1.1.0
Support NIC_BACKEND=ainic when building the MORI wheel so users targeting AMD Pensando NICs get libionic-dev / ionic-common.
Install common MoriIO proxy Python packages in the dev base image for disaggregated / KV workflows that use the proxy.

How to build

Default (no ionic):

DOCKER_BUILDKIT=1 docker buildx build \
            --file docker/Dockerfile.rocm_base \
            --tag rocm/vllm-dev:base \
            .

With AINIC / ionic:

DOCKER_BUILDKIT=1 docker build \
          --build-arg max_jobs=16 \
          --build-arg NIC_BACKEND=ainic \
          --build-arg BASE_IMAGE=rocm/vllm-dev:base \
          --tag  rocm/vllm-dev:latest \
          -f docker/Dockerfile.rocm .

Optional: --build-arg AINIC_VERSION=...

Test Plan

docker build -f docker/Dockerfile.rocm . (default NIC_BACKEND=none) completes.
docker build --build-arg NIC_BACKEND=ainic -f docker/Dockerfile.rocm . completes where AMD AINIC repo is reachable.
Inspect /app/versions.txt in the resulting image for MORI_NIC_BACKEND/AINIC_VERSION .

Code Review

This pull request updates the ROCm base Dockerfile to support MORI NIC backends, specifically adding support for AMD AINIC. It introduces new build arguments, installs MoriIO proxy dependencies, and refactors the MORI build stage with conditional logic for network interface controllers. Feedback was provided regarding inefficient apt-get operations in the build script and a shell syntax error where double dollar signs were used instead of single dollar signs for variable expansion.

+# MORI NIC backend (same pattern as SGLang docker/rocm.Dockerfile): use ainic for AMD Pensando + ionic packages
+ARG NIC_BACKEND=none


Since NIC_Backend is configurable, let's move this build to Dockerfile.rocm instead.

We would not want the user to rebuild all other dependencies especially torch and aiter which takes a few hours to compile, when they only want to install morii based for their NIC hardwares.

In other words, we do not wish to have any regular docker users rebuilding Dockerfile.rocm_base. Users should only need to rebuild Dockerfile.rocm in this case where NIC_Backend is configurable.

CC @gshtras

And is there a configuration that allow us to pre-build all the components for different NIC hardwares?

Hi @tjtanaa I have moved mori build and installation from rocm_base to rocm as it takes only 2 mins to build mori. PTAL

I'm strongly opposed to adding additional build steps into the Dockerfile.rocm
It should be kept clean and minimal, to allow quick builds of just vLLM
If MORI requires frequent changes, there should be a way to install it from prebuilt artifacts

As an alternative approach, I think it's viable to have the default build in the base image, the one that's going to be published to the wide public
In the .rocm dockerfile it's possible to add an optional target that will reinstall it with the required settings if anyone needs a custom image

@ichbinblau Hi latest mori tag is v1.1.0 where we are no longer specifying target nic support. All nic support happened just-in-time. So it is a good way to keep original build steps for mori and only bump the version to v1.1.0. Also agree with @gshtras we can add an option for user to decide installing related user space library in the .rocm dockerfile.

Hi @gshtras @billishyahao I have updated the source per your comments. PTAL.

+# Base deps, optional AMD AINIC (libionic-dev / ionic-common), USE_IONIC for CMake — see SGLang docker/rocm.Dockerfile MORI block


How long does this step take to build?

It takes round 2 mins to build mori.

LGTM. Thanks @ichbinblau . I will follow up with an update to the release pipeline to ship the docker image with different NIC hardware release.

tjtanaa · 2026-04-14T16:25:38Z

@ichbinblau which NIC backend that AMD would like to prefer to ship with? AINIC or BXNT ?

functionstackx · 2026-04-14T21:11:09Z

hi @tjtanaa

ideally there can be nightly/releases pipeline for vllm for AINIC images and another nightly/release pipeline for BXNT. images so that every night 2 images get built:

vllm/vllm-openai-rocm:nightly- default nightly (which includes MoRI with AINIC drivers/userspace packages)
vllm/vllm-openai-rocm:nightly--bxnt nightly with BXNT (which includes MoRI with BXNT drivers/userspace packages

Why is the build moved into Dockerfile.rocm from the base?

billishyahao · 2026-04-15T11:54:05Z

@tjtanaa Relying on auto-detection feature introduced in mori v1.1.0, we don't need to create two separate tags for image anymore ROCm/mori#182
