First, create the MySQL docker container using the following command

sudo docker run -e MYSQL_ROOT_HOST=your_ip -p 3309:3306 -e MYSQL_ROOT_PASSWORD=root mysql/mysql-server:latest

Now check the available docker container using the following command

sudo docker ps

once the container created a login to the container using the following command

sudo docker exec -it your_container_name /bin/bash

now connect the MySQL server

mysql -uroot -proot

Now once login to database create your database and enter the following command

ALTER USER ‘root’@’your_ip' IDENTIFIED WITH mysql_native_password BY ‘root’;

Bingo that’s all you have to do to connect to docker MySQL

Now exit from the docker and MySQL with your local pc.
