 RUN mkdir / sparrow 
 RUN cp -a / tmp / node_modules / sparrow 
 
 WORKDIR / sparrow 
添加。 / sparrow / 
运行npm运行build 
 
＃ssh keys 
 WORKDIR / root 
 RUN mv /sparrow/.ssh / root / 
 
＃上传js和css 
 WORKDIR / sparrow / build 
＃上传到S3！ 
 
＃返回/ sparrow 
 WORKDIR / sparrow

解决方案

以
Docker构建无法解析archive.ubuntu.com apt-get无法安装任何内容

这也影响了yum和其他repo管理器，因为我们希望它们可以访问，但容器只有主持人允许的网络设置

我喜欢在脚本开头添加这些行：

  #DNS更新：这是运行yum并让Docker构建进程访问互联网所必需的。 
 RUNsh-cecho nameserver 8.8.8.8>> /etc/resolv.conf
  

更新：
从以下评论中：当您在WiFi网络之间或家庭和工作之间的网络之间移动时，容器不知道它在新的网络中。重新启动VM或Docker机器是最好的解决方案。

I cannot build my image with the following Dockerfile:

FROM ubuntu

RUN apt-get -y update && apt-get -y install \
nodejs npm ssh

# cache npm install when package.json hasn't changed
WORKDIR /tmp
ADD package.json package.json
RUN npm install
RUN npm install -g pm2

RUN mkdir /sparrow
RUN cp -a /tmp/node_modules /sparrow

WORKDIR /sparrow
ADD . /sparrow/
RUN npm run build

# ssh keys
WORKDIR /root
RUN mv /sparrow/.ssh /root/

# upload js and css
WORKDIR /sparrow/build
# UPLOAD TO S3!

# go back to /sparrow
WORKDIR /sparrow

ENV NODE_ENV production
ENV NODE_PATH "./src"

EXPOSE 8000
CMD ["pm2", "start", "./bin/server.js", "--no-daemon", "-i", "0"]

Seems like it's having trouble connecting to the internet to install ubuntu packages and failing with:

Any suggestions for how to resolve or test this problem? Running on El Capitan OSX

Thanks!

This has been answered at Docker build "Could not resolve 'archive.ubuntu.com'" apt-get fails to install anything

This also affects yum and other repo mangers since we expect them to be accessible but the containers have only the network settings allowed in the host

I like to add these lines at the start of my scripts:

#DNS update: This is needed to run yum and to let the docker build process access the internet. 
RUN "sh" "-c" "echo nameserver 8.8.8.8 >> /etc/resolv.conf"

Update: From the comments below: when you move between networks say between wifi networks or between home and work the container doesn't know it's in a new network. Restarting the VM or Docker machine is the best fix.
