Adding packages to dind runner without setup- action

[brinkercode]

I have a need for package management during automation but deploying them during a workflow is a bit counter-productive for time and consistency. How would I ref the DIND image so that the runner itself has the packages on spin-up not just the controller? Basic Dockerfile for example:

FROM summerwind/actions-runner-dind

## Dependencies
# APT packages and python
RUN sudo apt-get update -y \
    && sudo apt-get install -y apt-utils libsnappy-dev cmake build-essential libopenblas-dev liblapack-dev python3-dev python3.8-venv \
    && sudo apt-get upgrade -y \
    && sudo rm -rf /var/lib/apt/lists/*

# Pip packages
COPY requirements.txt /
RUN pip install -r requirements.txt

ENV PATH=$PATH:/usr/local/bin:$GITHUB_PATH:
ENV ACTIONS_RUNNER_FORCE_ACTIONS_NODE_VERSION=16
HEALTHCHECK --interval=5m --timeout=3s \
CMD curl -f http://localhost/ || exit 1

requirements.txt

###### Requirements without Version Specifiers ######
docstr-coverage
flake8-junit-report 
mypy
pandas
pydocstyle
pylint 
pylint-fail-under 
pylint-junit

###### Requirements with Version Specifiers ######
flake8==3.8.4 
flake8-import-graph==0.1.3
poetry==1.0.10

Above will result in the controller having the package requirements, but unable to utilize those packages when a runner is processing a job. Any help or ideas appreciated.

After further investigation -- the issue was with an even deeper virtual environment being created due to poetry. Working around the poetry issue. Discussion topic can be deleted if not otherwise useful as the initial question is irrelevant currently.
