错误 发生意外错误："https://registry.yarnpkg.com/ansi-regex/-/ansi-regex-5.0.1.tgz: getaddrinfo EAI_AGAIN reg

Question

我遵循Docker官方指南中的指南，指南->Get started->Part 2: Containerize an application.

1. git clone https://github.com/docker/getting-started.git

2. 然后我创建了一个Dockerfile，内容如下:

   # syntax=docker/dockerfile:1
   FROM node:18-alpine
   WORKDIR /app
   COPY . .
   RUN yarn install --production
   CMD ["node", "src/index.js"]
   EXPOSE 3000
   

3. 我试图构建它，但发生错误

docker build -t getting-started .

错误信息如下:

这是我的环境:

• WIN10 Family Edition 22H2
• Docker Desktop 4.15.0 (93002)
  我已经尝试添加命令

yarn config set registry http://registry.npm.taobao.org/

在Dockerfile中，但这仍然发生了。修改后的Dockerfile如下:

# syntax=docker/dockerfile:1
FROM node:18-alpine
WORKDIR /app
COPY . .
RUN yarn config set registry http://registry.npm.taobao.org/ && yarn install --production
CMD ["node", "src/index.js"]
EXPOSE 3000

仍然没有修复错误。我找不到日志文件/app/yarn-error.log

Answer 1

你可能想要阅读docker build giving error in "yarn install"它详细地讨论了这个问题。

总而言之，这是一个网络和安全问题，尽管似乎有办法通过改变Dockerfile的内容来解决这个问题。，最简单的方法就是直接连接到另一个网络。

我用两台连接到同一网络的Windows 10电脑(在我家里，而不是公司网络)测试了这一点，两台电脑在docker构建时都失败了。

然后我将两台计算机从该网络断开，并将它们连接到移动网络，并成功构建并运行getting started

请注意，我不需要更改docker入门教程中的任何内容。
