Step seven   perform docker Deploy

docker run -id \
>  -p 3306:3306 –name= mysql  -v $PWD/conf.d : /etc/mysql/conf.d  -v  $ PWD/logs : /logs   -v $PWD /data: /var/lib/mysql -e MYSQL_ROOT_PASSWORD=123456   mysql

I don’t know why I can’t write by myself

docker run -p 3306:3306 –name my-mysql  -e MYSQL_ROOT_PASSWORD=123456 -d mysql
