1.环境: ubuntu 16.0.4

2. 利用docker-compose（jenkins+tomcat+tomcat+mysql+redis+nginx）,java+maven直接在虚拟机里搭建。

3.docker-compose文件：

version: "3"

services:
  redis:
    # 指定镜像
    image: redis
    container_name: redis
    ports:
      # 端口映射

    restart: always
    volumes:
      # 目录映射
      - "./redis/conf:/usr/local/etc/redis"
      - "./redis/data:/data"
    command:
      # 执行的命令
      redis-server --appendonly yes

    volumes:

      #外部的Java和maven路径，这个需要挂载到jenkins里，要不然在设置jenkins的时候会提示找不到Java，maven路径		
      - "/usr/local/java/jdk1.8.0_211/bin/java:/usr/java/jdk1.8.0_211/bin/java"
      - "/usr/local/java/jdk1.8.0_211:/usr/java/jdk1.8.0_211"
