mapping native? 127.0.0.1?

did you use your local navicat to connect to the mysql in Aliyun docker?
mysql does not allow remote connections by default. You need to open remote connections in mysql.

docker has not been used, but it should be about the same as VM. Let's take a look at whether the mysql service is started. My telnet 139.199.17.176 3306 cannot be accessed. Normally, the firewall is enabled and port 3306 is not open.
in addition, it is recommended to perform select host,user from mysql.user; post to see

MySQL5.7 version can not be connected with Navicat for MySQL, to change to Navicat Premium or Workbench client
