Docker - Run MySQL

zzh@ZZHPC:~$ docker run -p 3306:3306 -e MYSQL_ROOT_PASSWORD=verysecretpass -e MYSQL_DATABASE=order mysql

In this case, our data source URL is
root:verysecretpass@tcp(127.0.0.1:3306)/order

 

docker run -d \
--name my-mysql \
-e MYSQL_ROOT_PASSWORD=my-secret-pw \
-v /your/local/path/mysql-data:/var/lib/mysql \
mysql:8

 

zzh@ZZHPC:~$ docker run --name mysql8 -p 3306:3306 -e MYSQL_ROOT_PASSWORD=aaa -e MYSQL_DATABASE=simple_bank -d mysql
