搬運工構建與失敗無法解析「archive.ubuntu.com」

Question

我無法與以下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"] 

好像它有連接到互聯網，安裝Ubuntu的軟件包，並與失敗的煩惱：

Err http://archive.ubuntu.com trusty-updates InRelease 

Err http://archive.ubuntu.com trusty-security InRelease

有關如何解決或測試此問題的任何建議？在El Capitan OSX上運行

謝謝！

Answer 1

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

已回答這也影響百勝等回購經理，因爲我們希望他們可以訪問，但集裝箱已使主機

我只喜歡網絡設置

#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： 從下面的意見：在我的腳本開始添加這些線WH如果你在網絡之間移動，說wifi網絡之間或家庭與工作之間的容器不知道它在一個新的網絡。重新啓動VM或Docker機器是最好的解決方案。

Answer 2

參見https://github.com/boot2docker/boot2docker/issues/451#issuecomment-65432123。可能發生的情況是您的VirtualBox NAT DNS代理具有陳舊的路由。您通常必須重新啓動虛擬機才能再次運行。

另一個解決方法是讓虛擬機使用您的主機解析器（當DHCP實施新的名稱服務器時應更新它）。假設你的機器下泊塢窗機命名爲dev，你可以這樣做：

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

Answer 3

在Ubuntu主機我在/ etc /默認以下條目/泊塢窗

DOCKER_OPTS="--dns 172.21.32.182" 

，然後：

sudo systemctl daemon-reload 
sudo systemctl restart docker 

有助於解決網絡連接問題。當然你需要用你的dns替換172.21.32.182。

Answer 4

泊塢構建失敗，因爲警告 ---> [Warning] IPv4 forwarding is disabled. Networking will not work ，即使你可以在防火牆上解決archive.ubuntu.com 解決方案 -

• 。
• 在我的情況下centos7-添加到 /etc/sysctl.conf中：把net.ipv4.ip_forward = 1
• 應用sysctl設置： 的sysctl -p
