dockerCompose批量部署docker项目

dockerCompose批量部署docker项目

1. 项目打包

	### 1.1  非compose配置文件url写ip

spring:
  redis:
    host: 127.0.1.1
  datasource:
    type: com.alibaba.druid.pool.DruidDataSource
    driverClassName: com.mysql.cj.jdbc.Driver
    druid:
       url: jdbc:mysql://127.0.1.1:3306/test?useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=true  

	### 1.2 使用compose配置文件url写服务名

spring:
  redis:
    host: redis
  datasource:
    type: com.alibaba.druid.pool.DruidDataSource
    driverClassName: com.mysql.cj.jdbc.Driver
    druid:
      url: jdbc:mysql://mysql:3306/test?useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=true    

2. 编写dockerFile

#base image
FROM adoptopenjdk/openjdk8:latest
#类似于执行 linux指令
RUN mkdir /opt/app
#类似于linux copy指令
COPY springboot-0.2.jar /opt/app/
#对外端口
EXPOSE 8080
#执行命令 java -jar /opt/app/springboot-0.2.jar
CMD ["java", "-jar", "/opt/app/springboot-0.2.jar"]

3. 打包镜像

# .代表DockerFile在当前目录
docker build -t name:0.2 .

3.1 修改镜像名称和tag

docker tag [imgid] [name]:[tag]
#修改后使用[name]:[tag]删除原镜像

4. 编写docker-compose.yml（严格要求缩进）

version: "3"
services:
    microService:
        image: order:0.2
        container_name: ms01
        ports:
          - "8080:8080"
        depends_on:
          - redis
          - mysql
    redis:
        image: redis
        ports:
          - "6379:6379"
        volumes:
          - /home/docker/redis/conf/redis.conf:/etc/redis/redis.conf
          - /home/docker/redis/data:/data
        command: redis-server /etc/redis/redis.conf
    mysql:
        image: mysql:5.7.41
        environment: 
            MYSQL_ROOT_PASSWORD: 'PASSWORD'
            MYSQL_ALLOW_EMPTY_PASSWORD: 'no'
            MYSQL_DATABASE: 'test'
            MYSQL_USER: 'root'
            MYSQL_PASSWORD: 'PASSWORD'
        ports:
          - "3306:3306"
        volumes:
          - /home/mysql/data:/var/lib/mysql
          - /home/mysql/conf:/etc/mysql/conf.d
          - /home/mysql/log:/var/log/mysql
        command: --default-authentication-plugin=mysql_native_password #解决外部无法访问

5. 启动/关闭项目

#尽量在docker-compose.yml所在文件夹执行命令
#启动命令
docker-compose up -d
#关闭命令
docker-compose stop
