代理后面的Docker Centos 7 easy_install supervisor ssl问题

在过去的两天里,我正在阅读docker-container并尝试设置Apache容器.

我支持代理.以下是我的Dockerfile的内容.

FROM centos:latest
ENV http_proxy 
ENV https_proxy 
ENV ftp_proxy 
RUN yum -y update
RUN yum -y install python-setuptools
RUN easy_install supervisor
RUN mkdir -p /var/log/supervisor
RUN yum -y install which
RUN yum -y install git

一切都很顺利RUN easy_install supervisor.我收到以下错误.

Step 6 : RUN easy_install supervisor
