概述
我們使用前面《SpringCloudAlibaba注冊中心與配置中心之利器Nacos實戰與源碼分析（中）》的兩個微服務示例，分別是庫存微服務和訂單微服務，基於Nacos注冊中心和配置中心的使用，前面Nacos我們已基於dock-compose方式部署，我們增加配置數據，這里我們暫時也不把數據打包進去，各位可以直接將容器以dokcer export方式導入為鏡像，微服務使用訂單、庫存MySQL數據庫暫時也不單獨做成鏡像，各位可以做成SQL腳本執行導入方式。
整體工程結構
- docker目錄docker compose編排腳本目錄
- bin目錄：包含初始化腳本、啟動腳本、停止腳本、更新腳本
- env目錄：存在為微服務環境變量
- yaml目錄：存在全局環境腳本變量、微服務docker-compose腳本
- 庫存微服務
- bin目錄：存在微服務啟動腳本
- conf目錄：存在啟動配置文件和日志配置文件
- Dockerfile文件
- 訂單微服務
- bin目錄：存在微服務啟動腳本
- conf目錄：存在啟動配置文件和日志配置文件
- Dockerfile文件

上面訂單微服務pom文件添加docker-maven-plugin，mvn install階段，當執行mvn install時 就會執行docker build 和docker push，我們前面也介紹Docker Harbor私有倉庫的部署，可以通過插件直接推送內網的Harbor私有倉庫里。
打包
# 由於需要進行docker build 和docker push，打包機器需要安裝docker，直接執行mvn clean install 即可，如果需要單獨mvn clean install# 如果是單獨針對庫存微服務只進行docker build，可以進入庫存微服務目錄mvn clean package docker:bulid
docker build兩個微服務的鏡像文件如下，這個是我單獨docker build沒有push.如果install的話上傳內網Harbor倉庫本地先生成鏡像，然后再上傳最后刪除本地的鏡像。
部署
env目錄
訂單微服務環境變量ecom-order-service.env，這里NACOS_CONFIG_SERVER簡單先用地址，如果是在單個宿主機或者K8s環境下，並且在同個容器網絡內可以直接使用容器名，可不需要Nacos地址配置，這里我們就先用暴露宿主機端口，先重點放在兩個微服務容器上。
SPRING_PROFILES_ACTIVE=dev
NACOS_CONFIG_SERVER=192.168.50.95:8848

制作Docker-Compose編排文件
我這里做法沒有將多個微服務編排的一個Docker-Compose文件里，而已單獨做一個Docker-Compose，通過shell腳本串聯起來執行，各位也可以直接編寫一個Docker-Compose
全局環境變量.env存放全局參數信息，例如各微服務的版本信息
ECOM_STORAGE_VERSION=1.0ECOM_ORDER_VERSION=1.0
庫存微服務Docker-Compose文件ecom-storage-service.yml,如果是本地build則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:

volumes:

ports:
- "4080:4080"
networks:

restart: always
networks:
simple_ecommerce:

訂單微服務Docker-Compose文件ecom-order-service.yml

Usage:
$WAITFORIT_cmdname host:port [-s] [-t timeout] [-- command args]
-h HOST | --host=HOST Host or IP under test
-p PORT | --port=PORT TCP port under test
Alternatively, you specify the host and port as host:port
-s | --strict Only execute subcommand if the test succeeds
-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

查看容器運行情況，容器正常運行
查看nacos服務的注冊信息
訪問訂單接口http://192.168.50.95:4070/create/1001/1001/3 ，返回成功結果
查看訂單表和庫存表的數據都已更新，至此部署完畢
