在 Docker 构建期间安装自制程序包

Question

我正在尝试安装 docker 映像，并希望在运行容器时预安装某些 Homebrew 软件包。我能够很好地构建它并且版本语句按预期工作但是当我运行时安装的包丢失了。知道我做错了什么吗？

RUN git clone https://github.com/Homebrew/brew ~/.linuxbrew/Homebrew \
&& mkdir ~/.linuxbrew/bin \
&& ln -s ../Homebrew/bin/brew ~/.linuxbrew/bin \
&& eval $(~/.linuxbrew/bin/brew shellenv) \
&& brew --version \
&& brew tap aws/tap && brew install aws-sam-cli \
&& sam --version

您必须在 Dockerfile 中设置 PATH 环境变量：

ENV PATH=~/.linuxbrew/bin:~/.linuxbrew/sbin:$PATH

这是一个完整的工作 Dockerfile：

FROM debian
RUN apt-get update && apt-get install -y git curl binutils clang make
RUN git clone https://github.com/Homebrew/brew ~/.linuxbrew/Homebrew \
&& mkdir ~/.linuxbrew/bin \
&& ln -s ../Homebrew/bin/brew ~/.linuxbrew/bin \
&& eval $(~/.linuxbrew/bin/brew shellenv) \
&& brew --version \
&& brew tap aws/tap && brew install aws-sam-cli \
&& sam --version
ENV PATH=~/.linuxbrew/bin:~/.linuxbrew/sbin:$PATH
