如何将brew安装到Dockerfile (`brew: not `brew‘)

Question

与其在a two-year old thread上发表文章，我决定提出一个新的问题。

我希望将brew (homebrew)添加到Docker容器中，但是我得到了一个brew: not found错误。

上一篇文章中建议的解决方案似乎行不通。这个新的文件..。

FROM rust:1.63.0-buster
WORKDIR app

RUN apt-get update && \
    apt-get install -y -q --allow-unauthenticated \
    git \
    sudo
RUN useradd -m -s /bin/zsh linuxbrew && \
    usermod -aG sudo linuxbrew &&  \
    mkdir -p /home/linuxbrew/.linuxbrew && \
    chown -R linuxbrew: /home/linuxbrew/.linuxbrew
USER linuxbrew
RUN /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

USER root
RUN chown -R $CONTAINER_USER: /home/linuxbrew/.linuxbrew

RUN brew install hello

给出这个错误..。我遗漏了什么？谢谢。

 => ERROR [6/6] RUN brew install hello                                                                   0.2s

这个Dockerfile在/home/linuxbrew/.linuxbrew/bin/brew中安装brew。在path中包含这个目录(使用ENV命令)就可以做到这一点。

...
ENV PATH="/home/linuxbrew/.linuxbrew/bin:${PATH}"
RUN brew install hello
