docker 容器 Mysql 端口外部访问问题

Question

I've a mysql inside docker container, which is running on the server. And I can run it normally inside the container using

mysql -u root -h localhost --port=3306 -p

I've mapped the container 3306 to host 33069 port.

netstat -tnlp | grep :33069

the above command runed on the server shows me the following result

tcp6       0      0 :::33069                :::*                    LISTEN      120562/docker-proxy

from which it's clear that mysql is available not only for localhost . However when I try to connect to the mysql from my local machine using the command

mysql -u root -h myAddress.com --port=33069 -p

I get the error Can't connect to MySQL server on... after timeout. What I've missed?

Answer 1

if you are using the docker run command, the container's port 3306:33069 needs to be exposed, and the docker MySql container host's server port, if the firewall is enabled for the port 33069.

Afterwards on your local pc, the port 33069 needs to be open, to communicate to MySql docker container.
