SpringCloudAlibaba微服务docker容器打包和部署示例实战

2022年5月18日09:37:40

概述

我们使用前面《SpringCloudAlibaba注册中心与配置中心之利器Nacos实战与源码分析（中）》的两个微服务示例，分别是库存微服务和订单微服务，基于Nacos注册中心和配置中心的使用，前面Nacos我们已基于dock-compose方式部署，我们增加配置数据，这里我们暂时也不把数据打包进去，各位可以直接将容器以dokcer export方式导入为镜像，微服务使用订单、库存MySQL数据库暂时也不单独做成镜像，各位可以做成SQL脚本执行导入方式。

整体工程结构

  • docker目录docker compose编排脚本目录
    • bin目录：包含初始化脚本、启动脚本、停止脚本、更新脚本
    • env目录：存在为微服务环境变量
    • yaml目录：存在全局环境脚本变量、微服务docker-compose脚本
  • 库存微服务
    • bin目录：存在微服务启动脚本
    • conf目录：存在启动配置文件和日志配置文件
    • Dockerfile文件
  • 订单微服务
    • bin目录：存在微服务启动脚本
    • conf目录：存在启动配置文件和日志配置文件
    • Dockerfile文件

编写配置文件

      config:
        server-addr: ${spring.cloud.nacos.server-addr}
        file-extension: yaml

        extension-configs:

            group: commons-group

        shared-configs:

可以看到库存微服务pom文件添加docker-maven-plugin，mvn install阶段，当执行mvn install时 就会执行docker build 和docker push，我们前面也介绍Docker Harbor私有仓库的部署，可以通过插件直接推送内网的Harbor私有仓库里。

上面订单微服务pom文件添加docker-maven-plugin，mvn install阶段，当执行mvn install时 就会执行docker build 和docker push，我们前面也介绍Docker Harbor私有仓库的部署，可以通过插件直接推送内网的Harbor私有仓库里。

打包

# 由于需要进行docker build 和docker push，打包机器需要安装docker，直接执行mvn clean install 即可，如果需要单独mvn clean install# 如果是单独针对库存微服务只进行docker build，可以进入库存微服务目录mvn clean package docker:bulid

docker build两个微服务的镜像文件如下，这个是我单独docker build没有push.如果install的话上传内网Harbor仓库本地先生成镜像，然后再上传最后删除本地的镜像。

SpringCloudAlibaba微服务docker容器打包和部署示例实战

部署

env目录

订单微服务环境变量ecom-order-service.env，这里NACOS_CONFIG_SERVER简单先用地址，如果是在单个宿主机或者K8s环境下，并且在同个容器网络内可以直接使用容器名，可不需要Nacos地址配置，这里我们就先用暴露宿主机端口，先重点放在两个微服务容器上。

SPRING_PROFILES_ACTIVE=dev
NACOS_CONFIG_SERVER=192.168.50.95:8848
NACOS_CONFIG_NAMESPACE=a2b1a5b7-d0bc-48e8-ab65-04695e61db01
NACOS_CONFIG_GROUP=order-group
JAVA_OPT_EXT="-XX:+PrintGCDetails -XX:+PrintGCDateStamps -Xms1024m -Xmx1024m -Xmn1024m -XX:-UseAdaptiveSizePolicy -XX:SurvivorRatio=4 -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -XX:-CMSConcurrentMTEnabled -XX:CMSInitiatingOccupancyFraction=70 -XX:+CMSParallelRemarkEnabled -XX:MetaspaceSize=256m -XX:MaxMetaspaceSize=256m"

库存微服务环境变量ecom-storage-service.env

SPRING_PROFILES_ACTIVE=dev
NACOS_CONFIG_SERVER=192.168.50.95:8848
NACOS_CONFIG_NAMESPACE=a2b1a5b7-d0bc-48e8-ab65-04695e61db01

制作Docker-Compose编排文件

我这里做法没有将多个微服务编排的一个Docker-Compose文件里，而已单独做一个Docker-Compose，通过shell脚本串联起来执行，各位也可以直接编写一个Docker-Compose

全局环境变量.env存放全局参数信息，例如各微服务的版本信息

ECOM_STORAGE_VERSION=1.0ECOM_ORDER_VERSION=1.0

库存微服务Docker-Compose文件ecom-storage-service.yml,如果是本地build则image去掉registry.itxs.cn/

version: "3"
services:
  ecom-storage-service:
    image: registry.itxs.cn/simple_ecommerce/ecom-storage-service:${ECOM_STORAGE_VERSION}
    container_name: ecom-storage-service
    env_file:
      - ../env/ecom-storage-service.env
    volumes:
      - ../logs/ecom-storage-service/:/home/simple_ecommerce/ecom-storage-service/logs
    ports:
      - "4080:4080"
    networks:
      - simple_ecommerce
    restart: always
networks:
  simple_ecommerce:
    external: true

订单微服务Docker-Compose文件ecom-order-service.yml

version: "3"
services:
  ecom-order-service:
    image: registry.itxs.cn/simple_ecommerce/ecom-order-service:${ECOM_ORDER_VERSION}
    container_name: ecom-order-service
    env_file:
      - ../env/ecom-order-service.env
    volumes:
      - ../logs/ecom-order-service/:/home/simple_ecommerce/ecom-order-service/logs
    ports:
      - "4070:4070"
    networks:
      - simple_ecommerce
    restart: always
networks:
  simple_ecommerce:
    external: true

部署脚本
