docker發布nacos server通過docker-compose(將nacos配置保存到數據中)

• 直接通過docker啟動nacos-server

1. 簡單發布nacos-serve，直接拉取nacos-server鏡像，然后啟動docker即可
   ps如果啟動報錯，提示內存不夠，則修改docker啟動參數
   eg： docker run --name nacos -d -p 8848:8848 -e JVM_XMS=256m -e JVM_XMX=256m -e MODE=standalone  nacos/nacos-server:latest
   不過多解釋參數含義。
2. 啟動后查看服務是否正常使用即可，docker ps -a | grep nacos 查詢是否有該服務。
3. 如果有問題docker logs nacos查詢報錯信息。

• 通過docker-compose啟動，包含mysql配置設置

1. 在此不去解讀docker-compose的使用，提供配置信息
2. 文件結構
   

    

    

3. docker-compose.yml配置信息
   

   version: '2'
   services:
     nacos:
       image: nacos/nacos-server
       ports:
         - 8848:8848
       container_name: nacos
       environment:
         - JVM_XMS=256m
         - JVM_XMX=256m
         - MODE=standalone
       #掛載配置
       volumes:
         - ./nacos:/home/nacos/conf
       depends_on:
         - db
       # network_mode: bridge
       # networks:
       #   - default
       #   - outside
       # command: -e JVM_XMS=256m -e JVM_XMX=256m --env MODE=standalone 
     db:
       environment:
         MYSQL_ROOT_PASSWORD: "root1111"
         MYSQL_USER: "user"
         MYSQL_PASSWORD: "user1111"
         MYSQL_DATABASE: "nacos"
       image: "docker.io/mysql:latest"
       restart: always
       container_name: "mysql8.0"
       volumes:
         - "./mysql/db:/var/lib/mysql"
         - "./mysql/conf/:/etc/my.cnf"
       ports:
         - "23306:3306"
   # networks:
   #   outside:
   #     external: true

    application.properties配置信息
   使用nacos自帶的配置信息即可，需要注意的是需要打開mysql的配置，
   以及jdbc的url配置host要配置成docker-compose.yml中的services.db屬性中的container_name，這一點比較重要。

4. 拉取鏡像，docker-componse pull 
5. 啟動項目，docker-componse up -d 
   重啟，docker-compose.exe up -d --force-recreate
6. 啟動后訪問http://127.0.0.1:8848/nacos  用戶名密碼默認是nacos 查看nacos是否正常，連接mysql是否正常，
7. mysql啟動后需要自建表結構，將nacos提供的建表sql執行即可，當然這個地方可以優化成啟動mysql的鏡像的時候將建表語句通過腳本的方式執行，這樣是最好的。
8. 測試添加一個配置data_id后，mysql中config_info是否有數據
