Question

我在Ubuntu 16.04上

我对docker完全陌生，我正在尝试遵循本教程： https://docs.docker.com/get-started/part2/

当我给出命令时： docker build --tag bulletinboard:1.0 .

我被困在：

Step 4/7 : RUN npm install
 ---> Running in c39c53244bbc

我还尝试在--verbose命令后放置npm install，这除了卡住之外，我还能得到以下结果：

npm info it worked if it ends with ok
npm verb cli [ '/usr/local/bin/node', '/usr/local/bin/npm', 'install', '--verbose' ]
npm info using npm@6.14.4
npm info using node@v12.16.2
npm verb npm-session 6c1c828b01ec87d3
npm info lifecycle vue-event-bulletin@1.0.0~preinstall: vue-event-bulletin@1.0.0

npm verb stack     at processTimers (internal/timers.js:492:7)

npm verb argv "/usr/local/bin/node" "/usr/local/bin/npm" "install" "--verbose"
npm verb node v12.16.2
npm verb npm  v6.14.4
npm ERR! network timeout at: https://registry.npmjs.org/bootstrap
npm verb exit [ 1, true ]

这似乎是网络问题（即我的Docker容器无法连接到互联网）。我尝试了很多来自Internet的解决方案，但似乎没有任何效果对我有用。确实令人沮丧，因为这是Docker指南的第二篇教程。

能帮我吗？

Answer 1

这是一个简单的防火墙问题。

运行

sudo firewall-cmd --permanent --zone=trusted --add-interface=docker0

然后重新启动防火墙，

sudo systemctl restart firewalld

在Docker中构建并运行映像-网络问题
