[Bug]: Can't create non-root user using vllm/vllm-openai:v0.8.1 as a base image

[Searcherr]

Your current environment

U used to create a non-root user Docker image for vLLM and the following version was working fine up to v0.7.3:

FROM vllm/vllm-openai:v0.7.3

ENV PYTHONUNBUFFERED=1
ENV HF_HUB_CACHE=/api/models
ENV HF_HOME=/api/models

RUN mkdir -p /api/models/

# RUN chmod +x /api/entrypoint.sh
RUN chmod 777 -R /api \
  && umask 000

EXPOSE 8000

# Set user and group
ARG user=appuser
ARG group=appuser
ARG uid=1000
ARG gid=1000
RUN groupadd -g ${gid} ${group}
RUN useradd -u ${uid} -g ${group} -s /bin/sh -m ${user}
    
RUN chown ${user}:${group} /api

# Switch to user
USER ${uid}:${gid}

Today was trying to make the same with v0.8.1 and got permissions errors like this:
bash: /opt/venv/bin/vllm: /opt/venv/bin/python3: bad interpreter: Permission denied

To my understanding, in addition, /opt/venv/bin/python3 is actually a symbolic link pointing to /root/.local/share/uv/python/cpython-3.12.9-linux-x86_64-gnu/bin/python3.12

And even Dockefile modification that eventually has the following content does not work:

FROM vllm/vllm-openai:v0.8.1

ENV PYTHONUNBUFFERED=1
ENV HF_HUB_CACHE=/api/models
ENV HF_HOME=/api/models

RUN mkdir -p /api/models/

# Set user and group
ARG user=appuser
ARG group=appuser
ARG uid=1000
ARG gid=1000

# Create non-root user and group
RUN groupadd -g ${gid} ${group} \
    && useradd -u ${uid} -g ${group} -s /bin/sh -m ${user}

# Adjust permissions for Python environment and model directories
RUN chmod -R 777 /root/.local/share/uv/python/
RUN chown -R ${user}:${group} /api/models

# Ensure vllm workspace and virtual environment have correct permissions
ENV VIRTUAL_ENV="/opt/venv"
RUN chown -R ${user}:${group} /vllm-workspace \
    && chown -R ${user}:${group} ${VIRTUAL_ENV}

# Explicitly fix interpreter permissions
USER root
RUN chmod -R 755 ${VIRTUAL_ENV} \
    && chmod +x ${VIRTUAL_ENV}/bin/python3 \
    && chmod +x ${VIRTUAL_ENV}/bin/vllm \
    && chown -R ${user}:${group} ${VIRTUAL_ENV} \
    && chmod -R a+rX /root/.local/share/uv/python

# Restore non-root user context
USER ${uid}:${gid}

# Ensure PATH is correctly set
ENV PATH="${VIRTUAL_ENV}/bin:/home/${user}/.local/bin:${PATH}"

RUN chmod -R 777 /api && umask 000

EXPOSE 8000
WORKDIR /vllm-workspace

I would very appreciate if anyone shares his solution for this task or any advice in troubleshooting,
