今天部署一个复杂的application。源码地址：中的No.4中的example-voting-app。里面包括5个模块。
个人主页：idig.com
Voting App
暴露给外边访问的，投票使用，里面有对应的候选人的选项。是个python项目。这个将投票结果放入redis中，在现实中投票的人都比较多，为了方便存储直接连通的redis内存中。
Dockfile
# 使用python2.7的镜像FROM python:2.7# 设置一个application的目录WORKDIR /app# 文件依赖，安装指定的目录，通过pip进行安装ADD requirements.txt /app/requirements.txtRUN pip install -r requirements.txt# Copy our code from the current folder to /app inside the containerADD . /app# 暴露端口80EXPOSE 80 # 启动容器命令CMD ["python", "app.py"]复制代码
Results App
暴露给外边访问的，实时的显示候选人的得票情况。是个node js项目。直接取PG数据库的结果。
Dockfile
FROM node:0.10RUN mkdir /appWORKDIR /appADD package.json /app/package.jsonRUN npm install && npm lsRUN mv /app/node_modules /node_modulesADD . /appENV PORT 80EXPOSE 80CMD ["node", "server.js"]复制代码
worker
读取redis效果，并将结果记录到PG数据库，是个java项目。

Dockfile
FROM java:7RUN apt-get update -qq && apt-get install -y maven && apt-get cleanWORKDIR /codeADD pom.xml /code/pom.xmlRUN ["mvn", "dependency:resolve"]RUN ["mvn", "verify"]# Adding source, compile and package into a fat jarADD src /code/srcRUN ["mvn", "package"]CMD ["/usr/lib/jvm/java-7-openjdk-amd64/bin/java", "-jar", "target/worker-jar-with-dependencies.jar"]复制代码
整合docker-compose.yml
里面配置文件包括5个项目：voting-app，result-app，worker，redis，db
docker-compose.yml
version: "3"services: voting-app: build: ./voting-app/. volumes: - ./voting-app:/app ports: - "5000:80" links: - redis networks: - front-tier - back-tier result-app: build: ./result-app/. volumes: - ./result-app:/app ports: - "5001:80" links: - db networks: - front-tier - back-tier worker: build: ./worker links: - db - redis networks: - back-tier redis: image: redis ports: ["6379"] networks: - back-tier db: image: postgres:9.4 volumes: - "db-data:/var/lib/postgresql/data" networks: - back-tiervolumes: db-data:networks: front-tier: back-tier:复制代码
docker-compose 一键部署
到docker-compose.yml目录
sudo service docker restartsudo docker-compose up#查看eth1的ip地址 映射了2个端口5000和5001ip a复制代码
PS：有老铁在安装worker项目的maven的时候报插件错误

我更新了worker目录下的Dockerfile文件，使用阿里云maven仓库地址覆盖了原来的maven地址。我是先找到docker所在的容器，通过install maven的时候maven的安装路径：/usr/share/maven/conf/ ，然后将本地的settings.xml覆盖原来的地址就可以解决了。
