搬运工构建与失败无法解析“archive.ubuntu.com”

Question

我无法与以下Dockerfile打造自己的形象：

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"] 

好像它有连接到互联网，安装Ubuntu的软件包，并与失败的烦恼：

有关如何解决或测试此问题的任何建议？在El Capitan OSX上运行

谢谢！

Answer 1

这在 Docker build "Could not resolve 'archive.ubuntu.com'" apt-get fails to install anything

已回答这也影响百胜等回购经理，因为我们希望他们可以访问，但集装箱已使主机

我只喜欢网络设置

#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" 

更新： 从下面的意见：在我的脚本开始添加这些线WH如果你在网络之间移动，说wifi网络之间或家庭与工作之间的容器不知道它在一个新的网络。重新启动VM或Docker机器是最好的解决方案。

Answer 2

参见https://github.com/boot2docker/boot2docker/issues/451#issuecomment-65432123。可能发生的情况是您的VirtualBox NAT DNS代理具有陈旧的路由。您通常必须重新启动虚拟机才能再次运行。

另一个解决方法是让虚拟机使用您的主机解析器（当DHCP实施新的名称服务器时应更新它）。假设你的机器下泊坞窗机命名为dev，你可以这样做：

docker-machine stop dev 
VBoxManage modifyvm dev --natdnsproxy1 off --natdnshostresolver1 off 
docker-machine start dev 

Answer 3

在Ubuntu主机我在/ etc /默认以下条目/泊坞窗

DOCKER_OPTS="--dns 172.21.32.182" 

，然后：

sudo systemctl daemon-reload 
sudo systemctl restart docker 

有助于解决网络连接问题。当然你需要用你的dns替换172.21.32.182。

Answer 4

泊坞构建失败，因为警告 ---> [Warning] IPv4 forwarding is disabled. Networking will not work ，即使你可以在防火墙上解决archive.ubuntu.com 解决方案 -

• 。
• 在我的情况下centos7-添加到 /etc/sysctl.conf中：把net.ipv4.ip_forward = 1
• 应用sysctl设置： 的sysctl -p
