最近需要开多个项目及多个模块,以前采用的是将jar包打进镜像里,现在多个项目多个模块多个环境就不好管理,制作此通用jar包镜像

### dockerfile ###

FROM openjdk:8-jre-alpine
    MAINTAINER    xuming<xuming9@163.com>
    LABEL description="public docker image.see readme.txt for more information "
    
    #modify timezone
    ENV TZ=Asia/Shanghai
    RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone
    #chinese
    ENV LANG C.UTF-8
    
    #auto run jar when starting
    ENTRYPOINT ["sh","/app_start.sh"]

#### build镜像 ####

docker build -t "pulic-image" .

### app\_start.sh ###

#!/bin/bash
    sh path/start.sh -a env_name -p jar_name

### [start.sh][] ###

#!/bin/bash
    param1=$1
    value1=$2
    param2=$3
    value2=$4
    param3=$5
    value3=$6
    active=test
    project=${
        PWD##*/}
    otherParams=""
    
    if [ "$param1" == "-a" ]; then
        if [ $value1 ]; then
            active=$value1
        fi
    fi
    
    if [ "$param2" == "-p" ]; then
        if [ $value2 ]; then
            project=$value2
        fi
    fi
    
    if [ "$param3" == "-o" ]; then
        if [ $value3 ]; then
            otherParams=$value3
        fi
    fi
    java -jar ${project}".jar" --spring.profiles.active=${active} ${otherParams}

### docker-compose ###

version: '2'
    services:
        eureka:
            image: public-image
            container_name: "platform-eureka"
            volumes:
                - /data/docker/platform/eureka/platform-service-eureka.jar:/platform-service-eureka.jar
                - /data/docker/platform/eureka/app_start.sh:/app_start.sh
                - /data/docker/public_image/start.sh:/start.sh
            ports:
                - "20100:20100"
        config:
            image: public-image
            container_name: "platform-config"
            volumes:
                - /data/docker/platform/config/platform-service-config.jar:/platform-service-config.jar
                - /data/docker/platform/config/app_start.sh:/app_start.sh
                - /data/docker/public_image/start.sh:/start.sh
            ports:
                - "20200:20200"
            depends_on:
                - "eureka"

公共镜像使用说明

1.  将app\_start.sh挂载至容器根目录
2.  运行jar包所在目录的文件名与jar包文件名相同
3.  将start.sh挂载至jar包所在目录
4.  修改app\_start.sh  
    4.1 修改start.sh的路径(path)  
    4.2 修改环境名称(env\_name)  
    4.3 修改jar包名称(jar\_name)

提示: 请根据jar包依赖jdk自行下载openjdk版本镜像,并修改dockerfile
