FYI, you can use "heredoc" syntax for RUN commands in your Dockerfile, which makes it easier to read and maintain:

FROM debian:11

ARG MINIFORGE_VERSION="24.11.2-1"
RUN <<EOF
apt-get update -y
apt-get install -y vim wget git
apt-get clean all
EOF

RUN groupadd conda-users

RUN <<EOF
wget -O Miniforge3-installer.sh https://github.com/conda-forge/miniforge/releases/download/${MINIFORGE_VERSION}/Miniforge3-${MINIFORGE_VERSION}-Linux-x86_64.sh
bash Miniforge3-installer.sh -b -p /opt/conda
rm Miniforge3-installer.sh
chgrp -R conda-users /opt/conda/ && chmod -R 775 /opt/conda/
/opt/conda/bin/conda clean -afy
echo "source /opt/conda/etc/profile.d/conda.sh" >> /root/.bashrc
EOF

ENV PATH=/opt/conda/bin:$PATH
