环境
默认你已安装好docker环境
django项目大概结构
(p3s) [root@opsweb]# tree opsweb opsweb ├── apps ├── logs ├── manage.py ├── media ├── opsweb ├── README.md ├── requirements.txt └── static
编写Dockerfile
这里指定 Python 版本为docker官方提供的
"0.0.0.0:8000" 这里笔者开启容器中 8000 端口 FROM python:3.6 RUN mkdir -p /usr/src/app COPY pip.conf /root/.pip/pip.conf COPY opsweb /usr/src/app/ COPY run_web.sh /usr/src/app/ RUN pip install -r /usr/src/app/requirements.txt WORKDIR /usr/src/app CMD [ "sh", "./run_web.sh"]
编写pip文件
这里是为了使用镜像 pip install速度快些 使用阿里云源
[global] index-url = http://mirrors.aliyun.com/pypi/simple/ [install] trusted-host=mirrors.aliyun.com
完整目录结构
[root@opsweb]# ls Dockerfile opsweb pip.conf run_web.sh
build镜像
docker build -t ops:v0.1 . Sending build context to Docker daemon 4.849 MB Step 1 : FROM python:3.6 ---> 3e4c2972dc8d Step 2 : RUN mkdir -p /usr/src/app ---> Running in 8ddd929f5c18 ---> 89dc0a1ffdf0 Removing intermediate container 8ddd929f5c18 Step 3 : COPY pip.conf /root/.pip/pip.conf ---> 5a4a165fed90 Removing intermediate container 37f3fdc7e5d2 Step 4 : COPY opsweb /usr/src/app/opsweb ---> f602e72ffd4c Removing intermediate container 8d4bb616916d Step 5 : COPY opsweb/requirements.txt /usr/src/app/ ---> 6fe11a6fcbe0 Removing intermediate container faeadee32fed Step 6 : RUN pip install -r /usr/src/app/requirements.txt ---> cc09c17d53da Removing intermediate container d7b45bec6993 Step 7 : WORKDIR /usr/src/app ---> Running in c22dfdddbe81 ---> c5c944b6df45 Removing intermediate container c22dfdddbe81 Step 8 : CMD python ./manage.py runserver 0.0.0.0:8000 ---> Running in 29d5f0f53f6e ---> 10d37173fd13 Removing intermediate container 29d5f0f53f6e Successfully built 10d37173fd13
结语
这样镜像就build好了,然后你可以直接docker run -p8000:8000 ops:v0.1 -d启动就行,或者也可以部署到k8s上去也很简单这里就不细讲了。
