如何在 Docker 容器内的 Ubuntu 上安装自制软件

Question

当我在 Ubuntu 18.04

上尝试 install 自制软件时

# Dockerfile
FROM ubuntu:18.04

RUN apt-get update && apt-get install build-essential curl file git -y
RUN sh -c "$(curl -fsSL https://raw.githubusercontent.com/Linuxbrew/install/master/install.sh)"

出现错误：

==> Add Ruby to your PATH by running: PATH=/root/.linuxbrew/Homebrew/Library/Homebrew/vendor/portable-ruby/current/bin:$PATH Don't run this as root!

Answer 1

您有什么理由不能使用 official image (docker pull linuxbrew/linuxbrew)？它基于 Ubuntu 16.04 / Xenial。

如果一定要使用Bionic(18.04)，正确安装homebrew的方法是按照官方Dockerfile.

中的步骤

但是要让您的 Dockerfile 正常工作，您需要安装 ruby，创建一个非 root 用户并以该用户身份执行安装脚本。像这样，

FROM ubuntu:18.04

RUN apt-get update && \
    apt-get install build-essential curl file git ruby-full locales --no-install-recommends -y && \
    rm -rf /var/lib/apt/lists/*

RUN localedef -i en_US -f UTF-8 en_US.UTF-8

RUN useradd -m -s /bin/bash linuxbrew && \
    echo 'linuxbrew ALL=(ALL) NOPASSWD:ALL' >>/etc/sudoers

USER linuxbrew
RUN sh -c "$(curl -fsSL https://raw.githubusercontent.com/Linuxbrew/install/master/install.sh)"

USER root
ENV PATH="/home/linuxbrew/.linuxbrew/bin:${PATH}"

PS：我添加了 --no-install-recommends 以忽略可选的依赖项，并添加了 rm -rf /var/lib/apt/lists/* 以删除 apt-get 剩余部分，从而减小了图像大小。此外，添加 locales 以安装 UTF-8 或 brew 将在您运行命令时发出警告。

Answer 2

新的正确方法是：

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)"

Answer 3

加布里埃尔的回答大部分对我有用，但漏掉了一步。我需要 chown /home/linuxbrew/.linuxbrew 文件夹给用户运行 Homebrew:

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