从 Intellij 的数据库工具连接到 MySql Docker-Container

Question

I have created a docker MySQL container like this

docker run --detach --name internal-mysql -p 6604:3306 -e MYSQL_ROOT_PASSWORD=user_pass -e MYSQL_DATABASE=internal -e MYSQL_USER=user -e MYSQL_PASSWORD=user_pass mysql

The container is running fine

CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES e802cd30e6a2 mysql "docker-entrypoint.s…" 42 seconds ago Up 41 seconds 33060/tcp, 0.0.0.0:6604->3306/tcp internal-mysql

Within the container I have checked the user host and it looks fine doesn't it?

+------------------+-----------+
| user             | host      |
+------------------+-----------+
| root             | %         |
| user             | %         |
| mysql.infoschema | localhost |
| mysql.session    | localhost |
| mysql.sys        | localhost |
| root             | localhost |
+------------------+-----------+

but when I try to connect to that DB from IntelliJ or my Spring-Boot app I always receive the same error

Of course I tried to google and figured out that for some cases it helped to figure out the container ip via docker inspect -f "{{range.NetworkSettings.Networks}}{{.IPAddress}}{{end}}" internal-mysql

which resulted in 172.17.0.2

I have tried to connect via jdbc:mysql://172.17.0.2:3306/internal-mysql

I have tried it with JDBC MYSQL Driver 8.0.21 and 5.1 with both no success.

Any idea please?

Since you published 3306 port of mysql container on port 6604 of your host - you should use 6604 port when trying to connect to your mysql docker container from the host.
