自己构建django的docker镜像

适用于新手学习，生产环境需要优化

FROM centos:7#继承centos

ADD epel.repo /etc/yum.repos.d#将epel源文件，拷贝到容器/etc/yum.repos.d，ADD相比COPY，还带压缩解压

RUN yum update -y#执行yum更新
RUN yum install -y python36#下载python36
RUN yum install -y python36-pip#下载pip工具
RUN pip3 install setuptools#下载setuptools
ADD Django-2.1.7.tar.gz /opt/#将当前tar.gz包解压并复制到容器opt下

WORKDIR /opt/#更换工作目录
RUN mv Django-2.1.7 django#将解压后的Django-2.1.7移动到django文件夹下

WORKDIR /opt/django
RUN python3 setup.py install#执行安装命令

WORKDIR /opt
RUN django-admin.py startproject mypro#创建django项目mypro
ADD run.sh /opt/mypro/run.sh#将run.sh拷贝容器内
RUN sed -i "s/ALLOWED_HOSTS = \[\]/ALLOWED_HOSTS = \['\*'\]/g" /opt/mypro/mypro/settings.py#更改ALLOWED_HOSTS让其他IP能访问

WORKDIR /opt/mypro
RUN chmod 777 run.sh

EXPOSE 8000#暴露端口8000
CMD ["/bin/sh","run.sh"]#执行run.sh
