[CI/Build] Add Dockerfile.cuda for NVIDIA GPU users

[loveysuby]

PLEASE FILL IN THE PR DESCRIPTION HERE ENSURING ALL CHECKLIST ITEMS (AT THE BOTTOM) HAVE BEEN CONSIDERED.

Purpose

Add Dockerfile.cuda for NVIDIA GPU users to build custom Docker images.

This addresses review feedback on PR #1386 that Dockerfile.ci is not suitable for end users:

• Installs unnecessary dev packages (.[dev])
• Has empty ENTRYPOINT requiring explicit vllm serve --omni
• Named/intended for CI-only use

The new Dockerfile follows the same structure as Dockerfile.rocm. (#280)

Build with a specific vLLM base image version (e.g. v0.14.0 - default: v0.15.0):

DOCKER_BUILDKIT=1 docker build -f docker/Dockerfile.cuda \
  --build-arg BASE_IMAGE=vllm/vllm-openai:v0.14.0 \
  -t vllm-omni-cuda .

Test Plan

Verified Dockerfile syntax with docker build --check across all official vLLM release versions:

cd vllm-omni/
curl -s "https://hub.docker.com/v2/repositories/vllm/vllm-openai/tags?page_size=100" \
  | jq -r '.results[].name' \
  | grep -E '^v[0-9]+\.[0-9]+\.[0-9]+$' \
  | sort -Vr \
  | while read version; do
      DOCKER_BUILDKIT=1 docker build --check -f docker/Dockerfile.cuda --build-arg BASE_IMAGE=vllm/vllm-openai:$version . || break
    done

Test Result

Remove inherited CMD from vllm-openai stage

The vllm-openai stage is built FROM final, so it inherits CMD ["/bin/bash"] from this stage; with ENTRYPOINT ["vllm", "serve", "--omni"], Docker will run vllm serve --omni /bin/bash by default, which passes /bin/bash as an extra argument and can break container startup unless users override the command. This affects the default build target because vllm-openai is the last stage in this Dockerfile.

Useful? React with 👍 / 👎.

Updated to use empty entrypoint for consistency with Dockerfile.rocm.

I was wondering if it might be helpful to use ENTRYPOINT ["vllm", "serve", "--omni"] as a common pattern for both Dockerfiles.rocm & .cuda.
