Error from server (BadRequest): error when creating "secrets.yaml": Secret in version "v1" cannot be handled as a Secret: v1.Secret.Data: decode base64: illegal base64 data at input byte 0, error found in #10 byte of ...|ord":"pwd","username|..., bigger context ...|{"apiVersion":"v1","data":{"password":"pwd","username":"usernametest"},"kind":"Secret","metad|...

可能为secret中data字段中的值不是正确的BASE64.可用如下java代码检测看看是否报错：

        String str= new String(Base64.getDecoder().decode("dmFsdWUtMg0K"));
        System.out.println(str);
