How to connect MySQL client with server running in Docker

Question

I am using Docker first time. I am trying to connect docker based MySQL with my Navicat client. How do I get docker IP and then use it for connection? Here are a few details:

CONTAINER ID        IMAGE                    COMMAND                  CREATED             STATUS              PORTS                                      NAMES

Answer 1

If you need to access the mysql container from the outside. Than you need to map the container port on the port of your server (using -p ).

docker run --name mysql -p 3306:3306 -e MYSQL_ROOT_PASSWORD=my-secret-pw  -e MYSQL_USER=test -e MYSQL_PASSWORD=test -d mysql:latest

Now you can connect to your container using the IP of your server + the port. In my case I'm in a VLAN. The IP of my server is 192.168.140.30. So eg when I ssh to my server I use that IP. Now I've mapped the port of my container on the port of my server (with -p 3306:3306 which means: map the port 3306 of my container to port 3306 of my server. (so I can use the server IP to connect).

If you need use client to connect to MySQL in Docker container you need do port mapping with the host machine.

I see you MySQL container not use mapping the container port to host port so you can not use MySQL client to connect the MySQL server.

You can use -p parameter specify the port mapping. for example if you need use port 3306 to connect to MySQL server, use following command to create the MySQL container. PS: you need change some setting for following command.

docker run --name container-name -d -p 3306:3306 -e MYSQL_ROOT_PASSWORD=password -e MYSQL_DATABASE=database-name -e MYSQL_USER=user -e MYSQL_PASSWORD=password  mysql:5.7
