SPRING_DATASOURCE_PLATFORM ：若不填，则默认创建内部数据库，若需使用外部数据库，填 mysql

部署命令

kubectl apply -f .

报错

Unknown column ‘encrypted_data_key’

原因

2.1.0版本config_info表中新增字段encrypted_data_key
2.1.0版本config_info_beta表中新增字段encrypted_data_key
2.1.0版本his_config_info表中新增字段encrypted_data_key

解决方案

1、新增字段

ALTER TABLE nacos.config_info ADD encrypted_data_key TEXT NOT NULL;
ALTER TABLE nacos.config_info_beta ADD encrypted_data_key TEXT NOT NULL;
ALTER TABLE nacos.his_config_info ADD encrypted_data_key TEXT NOT NULL;

2、降低 nacos 版本为 2.0.0
