SpringCloudAlibaba微服务docker容器打包和部署示例实战
2022/4/19 23:13:12
本文主要是介绍SpringCloudAlibaba微服务docker容器打包和部署示例实战，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！
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
库存微服务
编写配置文件

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。
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=devNACOS_CONFIG_SERVER=192.168.50.95:8848NACOS_CONFIG_NAMESPACE=a2b1a5b7-d0bc-48e8-ab65-04695e61db01NACOS_CONFIG_GROUP=order-groupJAVA_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"

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:${ECOM_STORAGE_VERSION} container_name: ecom-storage-service env_file: - ../env/ecom-storage-service.env volumes: - ../logs/ecom-storage-service/:/home/simple_ecommerce/ecom-storage-service/logs ports: - "4080:4080" networks: - simple_ecommerce restart: alwaysnetworks: simple_ecommerce: external: true
订单微服务Docker-Compose文件ecom-order-service.yml
version: "3"services: ecom-order-service: image: registry.itxs.cn/simple_ecommerce/ecom-order-service:${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: alwaysnetworks: simple_ecommerce: external: true
部署脚本
bin目录下我们创建操作脚本，init.sh初始化检查环境、安装docker和docker-compose、
#!/usr/bin/env bashecho "############当前操作系统版本##############"if ! type yum >/dev/null 2>&1; then echo "【ERROR】目前脚本仅支持CentOS7.X系统" exit 8else osVersion=$(echo `cat /etc/redhat-release | sed -r 's/.* ([0-9]+)\..*/\1/'`) if [[ "$osVersion" != "7" ]]; then echo "【ERROR】目前脚本仅支持CentOS7.X系统" exit 8 else echo '版本校验成功' fifiecho "############判断是否安装了docker##############"if ! type docker >/dev/null 2>&1; then echo 'docker 未安装'; echo '开始安装Docker....'; yum install -y yum-utils yum-config-manager \ --add-repo \ https://download.docker.com/linux/centos/docker-ce.repo #安装docker核心引擎、命令行客户端、容器 yum install docker-ce docker-ce-cli containerd.io echo 'docker 安装完毕'; #启动docker echo '配置Docker开启启动'; systemctl enable docker systemctl start dockercat >> /etc/docker/daemon.json << EOF{ "registry-mirrors": ["https://b9pmyelo.mirror.aliyuncs.com"]}EOF systemctl restart dockerelse echo 'docker 安装完毕';fiecho "############判断是否安装了wget##############"if ! type wget >/dev/null 2>&1; then echo 'wget 未安装'; echo '开始安装wget....'; yum -y install wgetelse echo 'wget 已安装';fiecho "############判断是否安装了dos2unix##############"if ! type dos2unix >/dev/null 2>&1; then echo 'dos2unix 未安装'; echo '开始安装dos2unix....'; yum -y install dos2unix*else echo 'dos2unix 已安装';fiecho "############判断是否安装了docker-compose##############"if ! type docker-compose >/dev/null 2>&1; then echo 'docker-compose 未安装'; echo '开始安装docker-compose....'; wget http://www.itxiaoshen.com:3001/assets/docker-compose chmod +x docker-compose mv docker-compose /usr/local/bin/ docker-compose -v echo 'docker-compose安装完毕....';else echo 'docker-compose 已安装';fiecho '创建simple_ecommerce网络';docker network create simple_ecommerce# 添加执行权限chmod +x ../bin/startup-all.shchmod +x ../bin/shutdown-all.shchmod +x ../bin/update.shchmod +x ../bin/wait-for-it.sh# 修改编码echo "修改编码...."dos2unix startup-all.shdos2unix shutdown-all.shdos2unix update.shdos2unix wait-for-it.shsh startup-all.sh

-q | --quiet Don't output any status messages
-t TIMEOUT | --timeout=TIMEOUT
Timeout in seconds, zero for no timeout
-- COMMAND ARGS Execute command with args after the test finishes

容器启动脚本startup-all.sh，其他只是示例流程，可以一步步完善补充

更新镜像脚本update.sh，包含关闭容器、下载新的镜像、启动容器
#!/usr/bin/env bash

sh shutdown-all.sh
#echo '=====开始更新ecom-gateway====='

执行测试
# 进入到bin目录下，由于我这里本地有镜像，少了pull流程 sh ./init.sh
查看容器运行情况，容器正常运行
查看nacos服务的注册信息
访问订单接口http://192.168.50.95:4070/create/1001/1001/3 ，返回成功结果
查看订单表和库存表的数据都已更新，至此部署完毕
