    apk add python3-dev python3 && \
    git clone --recursive  --depth 1 --branch v2 --single-branch  https://github.com/aws/aws-cli.git /aws-cli-sourcecode

RUN python -m venv venv && \
    . venv/bin/activate && \
    python3 -m ensurepip && \
    ln -s /usr/bin/pip3 /usr/bin/pip && \
    pip install setuptools && \
    scripts/installers/make-exe && \
    unzip -q dist/awscli-exe.zip && \
    aws/install --bin-dir /aws-cli-bin && \
    /aws-cli-bin/aws --version

Opened a fix for this in #10095. The root cause is an outdated pkg_resources.py2_warn hidden import in the PyInstaller hook that is no longer needed (resolved upstream in PyInstaller 5.5+), combined with setuptools >= 81 emitting a deprecation warning when pkg_resources is imported at runtime. The fix removes the outdated hidden import and adds a PyInstaller runtime hook to suppress the warning.
