It creates a bridge network called mysql_default，it is assigned a VIP 172.24.0.2 version: '2' se, its docker-compose.yml is as below. It starts 3 services, my observation is: 1) on the host machine, so I do a series of telnet connection test to the following IP-Port pairs a: (target at nacos containers with their VIPs in the overlay netw, successfully telnet to all the above IP-Port pairs 2) from inside mysql container: successfully telnet to a, what are the reasons? and how can I make the telnet successful?
