ARM64架构MacOS下Dockerfile安装Miniconda报错及解决

初始Dockerfile #

# installing conda
RUN wget https://repo.anaconda.com/miniconda/Miniconda3-latest-MacOSX-arm64.sh -O ~/miniconda.sh && bash ~/miniconda.sh -b -p $HOME/miniconda3 -b
ENV PATH=/$HOME/miniconda3/bin:$PATH
RUN conda update -y conda \
    && rm miniconda.sh

执行报错 #

executor failed running [/bin/sh -c wget https://repo.anaconda.com/miniconda/Miniconda3-latest-MacOSX-arm64.sh -O ~/miniconda.sh && bash ~/miniconda.sh -b -p $HOME/miniconda3 -b]: exit code: 127

报错原因明确：环境中缺少md5命令。

尝试brew安装未解决 #

添加以下指令安装brew及md5sha1sum后，仍出现相同报错：

# installing brew & md5sha1sum
RUN /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)" \
RUN brew install md5sha1sum

最终解决方法 #

改用CMD指令并创建md5的符号链接后问题解决，修改后的Dockerfile如下：

RUN wget https://repo.anaconda.com/miniconda/Miniconda3-latest-MacOSX-arm64.sh
CMD ["sudo ln -s md5sum /bin/md5"]
CMD ["chmod +x Miniconda3-latest-MacOSX-arm64.sh"]
CMD ["./Miniconda3-latest-MacOSX-arm64.sh -b -p $HOME/miniconda3 -b"]
ENV PATH=/$HOME/miniconda3/bin:$PATH
CMD ["conda update -y conda"]
RUN rm Miniconda3-latest-MacOSX-arm64.sh
