docker-django

配置

1. 在根目录创建Dockerfile

   FROM python:3
   ENV PYTHONUNBUFFERED 1
   WORKDIR /code/djangoblog/
   
   
   #RUN  apt-get install ln -sf /usr/share/zoneinfo/Asia/Shanghai  /etc/localtime \
   ADD requirements.txt requirements.txt
   RUN pip install --upgrade pip  && \
           pip install -Ur requirements.txt  && \
           pip install gunicorn[gevent] && \
           pip cache purge
   
   EXPOSE 8099
   ADD . .
   RUN chmod +x bin/docker_start.sh
   ENTRYPOINT ["bin/docker_start.sh"]
   

2. 创建需要的依赖的配置文件

   使用命令行创建
   pip freeze > requirements.txt 
   pip install -Ur requirements.txt
   

3. 创建在运行脚本

   #!/usr/bin/env bash
   python manage.py runserver 0.0.0.0:8099
   

打包成docker镜像

 docker build -t houses:v0.1 . 

推送和拉取到docker Hub

 //设置标签
 docker tag houses:v0.1 shanhui/houses:tagname
 //推送到docker Hub
 docker push shanhui/houses:tagname
 
 //拉取
 docker pull shanhui/houses:houses

docker运行Django

docker run -d  -p 8099:8099 3a16afa66aab[images]

删除容器

docker image rmi shanhui/houses:tagname

如果还有容器运行会报
Error response from daemon: conflict: unable to remove repository reference "shanhui/houses:tagname" (must force) - container 44d9766d8fd6 is using its referenced image 2b18f4236f3e

解决办法
 如果还有请反复执行
 docker stop 44d9766d8fd6
 docker rm 44d9766d8fd6
 docker image rmi shanhui/houses:tagname
