https://docs.docker.com/compose/rails/ 我跟着这个教程发现卡在了 apt-get 上

这个把-pp 去掉后打印的打印

➜  assign_docker docker-compose run web rails new . --force --no-deps --database=postgresql

一直卡在这儿，Get:5 http://deb.debian.org/debian buster/main amd64 Packages [7907 kB]

google 了下，docker build apt-get update stuck, 也没有合适的结果。。

代理开/关，全局/自动，各种情况都试过了。。

好像是网络哪里出问题了

试试在 apt-get update 前修改为国内的 debian mirror：

RUN cp /etc/apt/sources.list /etc/apt/sources.list.backup
RUN printf "deb http://mirrors.aliyun.com/debian stretch main \ndeb http://mirrors.aliyun.com/debian stretch-updates main \ndeb http://mirrors.aliyun.com/debian-security stretch/updates main\n" | cat - /etc/apt/sources.list.backup > /etc/apt/sources.list

以上代码未在 docker 测试，仅供参考思路

@zhengpd 谢谢，不过换了 source 之后，还是要重新 get 原先 source 的 buster 然后就又卡住了

没留意到是 buster，你把 printf 那行的 stretch 全部替换成 buster 试试

@zhengpd 老样子😅

source 确实换了，但是还是卡住了

应该就是网络问题 设置一下命令行的 http_proxy 变量，再 docker build 试试。

# 换源
RUN sed -i [email protected]@mirrors.tuna.tsinghua.edu.cn@g /etc/apt/sources.list
RUN sed -i [email protected]@mirrors.tuna.tsinghua.edu.cn@g /etc/apt/sources.list

RUN apt-get update && apt-get install -y nodejs postgresql-client

心血来潮，跟着教程试一试了。遇到了两个小坑（都有错误提示）：

  1. 要自己手动安装 bundler
  2. postgres 指定密码或者使用 POSTGRES_HOST_AUTH_METHOD: 'trust'

还有就是源的问题也要考虑进去。
