nacos v2.2 k8s部署启动报错：nacos server did not start because dumpservice bean construction failure. errMsg102, errllsg dataSource or tableName is null

背景#

最近搭建个nacos环境，用的镜像是2.2版本的，yaml如下：

nacos-conf

apiVersion: v1
kind: ConfigMap
metadata:
  name: nacos-cm
  namespace: nacos
data:
  mysql.host: "122.122.100.101" # mysql ip
  mysql.db.name: "nacos"      #上面创建数据库是指的的库名称
  mysql.port: "3306"           #端口
  mysql.user: "nacos_userName"          #用户
  mysql.password: "nacos_pwd"      #用户密码

          volumeMounts:
            - name: azure

        persistentVolumeClaim:
          claimName: mysql-pvc
  selector:
    matchLabels:
      app: nacos
      

一直报错：

nacos server did not start because dumpservice bean construction failure. errMsg:102, dataSource or tableName is null

我开始根据报错搜索，判断的原因有：

1、数据库连接信息不对，连不上；

2、MYSQL_SERVICE_DB_PARAM 这个环境变量没补上，要写上，明确给定时区；

结果发现这个发现是错的。

最后折腾了几天加了一个官方钉钉群，一个老哥幽幽地指出：

“你试试添加SPRING_DATASOURCE_PLATFORM”，然后我试试就逝世，加上了：

- name: SPRING_DATASOURCE_PLATFORM  #2.2版本一定要这个，官方的yaml漏了这个，不然会报错：
  value: "mysql"

启动成功！！WTF，官方示例太不讲究了，坑人！！！rnm，退钱！！诶，我好像没交钱，活生生把火憋了回去；
