docker - 为什么此Docker构建失败？

Question

以下是我的Dockerfile my-docker-file。

FROM ubuntu:14.04
RUN apt-get update
RUN apt-get -y upgrade
RUN apt-get install -y python python-pip git-all python-dev libxml2-dev libxslt1-dev libmysqlclient-dev gunicorn python-pycurl libcurl4-openssl-dev
RUN apt-get install -y rubygems-integration inotify-tools
RUN gem install sass -v 3.3.14
RUN apt-get install -y nodejs
RUN apt-get install -y npm
RUN npm install jsmin -g

但是它在最后一步中失败(请参见下文)。为什么会发生这种情况，我该如何解决？

$ docker build -f /path/to/my/project/my-docker-file .

这不是最好的解决方案，但这在这种情况下对我有用

FROM ubuntu:14.04
RUN apt-get update
RUN apt-get -y upgrade
RUN apt-get install -y python python-pip git-all python-dev libxml2-dev libxslt1-dev libmysqlclient-dev gunicorn python-pycurl libcurl4-openssl-dev
RUN apt-get install -y rubygems-integration inotify-tools
RUN gem install sass -v 3.3.14
RUN apt-get install -y nodejs
RUN apt-get install -y npm
RUN npm config set strict-ssl false <-- Ignore the SSL cert
RUN npm install jsmin -g

更新:

更好的解决方案是使用npm注册表的http版本，如下所示

FROM ubuntu:14.04
RUN apt-get update
RUN apt-get -y upgrade
RUN apt-get install -y python python-pip git-all python-dev libxml2-dev libxslt1-dev libmysqlclient-dev gunicorn python-pycurl libcurl4-openssl-dev
RUN apt-get install -y rubygems-integration inotify-tools
RUN gem install sass -v 3.3.14
RUN apt-get install -y nodejs
RUN apt-get install -y npm
RUN npm config set registry http://registry.npmjs.org/
RUN npm install jsmin -g
