Voting App

暴露給外邊訪問的，投票使用，裡面有對應的候選人的選項。是個python專案。這個將投票結果放入redis中，在現實中投票的人都比較多，為了方便儲存直接連通的redis記憶體中。

Dockfile

# 使用python2.7的映象
FROM python:2.7

# 設定一個application的目錄
WORKDIR /app

# 檔案依賴，安裝指定的目錄，通過pip進行安裝
ADD requirements.txt /app/requirements.txt
RUN pip install -r requirements.txt

# Copy our code from the current folder to /app inside the container
 

ADD . /app

# 暴露埠80
EXPOSE 80 

# 啟動容器命令
CMD ["python", "app.py"]

Results App

暴露給外邊訪問的，實時的顯示候選人的得票情況。是個node js專案。直接取PG資料庫的結果。

Dockfile

FROM node:0.10

RUN mkdir /app
WORKDIR /app

ADD package.json /app/package.json
RUN npm install && npm ls
RUN mv /app/node_modules /node_modules

ADD . /app

ENV PORT 80
 

EXPOSE 80

CMD ["node", "server.js"]

worker

讀取redis效果，並將結果記錄到PG資料庫，是個java專案。

Dockfile

FROM java:7

RUN apt-get update -qq && apt-get install -y maven && apt-get clean

WORKDIR /code

ADD pom.xml /code/pom.xml
RUN ["mvn", "dependency:resolve"]
RUN ["mvn", "verify"]

# Adding source, compile and package into a fat jar
 

ADD src /code/src
RUN ["mvn", "package"]

CMD ["/usr/lib/jvm/java-7-openjdk-amd64/bin/java", "-jar", "target/worker-jar-with-dependencies.jar"]

整合docker-compose.yml

裡面配置檔案包括5個專案：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-tier

volumes:
  db-data:

networks:
  front-tier:
  back-tier:

docker-compose 一鍵部署

到docker-compose.yml目錄

sudo service docker restart
sudo docker-compose up
#檢視eth1的ip地址 映射了2個埠5000和5001
ip a

PS：有老鐵在安裝worker專案的maven的時候報外掛錯誤

我更新了worker目錄下的Dockerfile檔案，使用阿里雲maven倉庫地址覆蓋了原來的maven地址。我是先找到docker所在的容器，通過install maven的時候maven的安裝路徑：/usr/share/maven/conf/ ，然後將本地的settings.xml覆蓋原來的地址就可以解決了。
