Daozy生产极限编程
以下是在MAC其他系统类似于上操作，需要更换相应的命令
安装Docker
# brew install --cask --appdir=/Applications docker 以下是安装成功

打开官网：https://hub.docker.com/
搜索django
$ docker pull django Using default tag: latest Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running? 这个报错是docker服务尚未启动。
方法 1 : 通过 launchctl 查看 docker server, 记住docker server 名:
$ launchctl list | grep docker - 0 com.docker.helper 86716 0 com.docker.docker.4180 然后关闭并启动它。
$ launchctl stop com.docker.docker.4180 && launchctl start com.docker.docker.4180 这种方法可能起不来。
方法 2 : 通过docker.app启动
$ open /Applications/Docker.app 继续安装django
# docker pull django 安装完成

自己build镜像
准备requirements.txt文件
pymongo==3.7.1 django==1.11.23 django-mongoengine==0.3.3 PyYAML==3.13 requests==2.8.1 准备Dockerfile文件：
FROM python:3.6 RUN apt-get update \ && apt-get install -y --no-install-recommends \ postgresql-client \ && rm -rf /var/lib/apt/lists/* WORKDIR /usr/src/app COPY . /user/src/app RUN pip install -r requirements.txt EXPOSE 8000 CMD ["python", "manage.py", "runserver", "0.0.0.0:8000"] COPY . /user/src/app 这句话的意思 ‘docker build -t daozy-django-app .’ 命令执行当前目录的内容copy到达容器/usr/src/app目录下。
build image
如果有问题，可能是你的文件位置不对。
