Setting a MySQL ContainerWhen you start the MySQL image, you can adjust the configuration of the MySQL instance by passing one or more environment variables on the docker run command line.

Starting a MySQL instanceDockerfile

docker \

run \

--detach \

--env MYSQL_ROOT_PASSWORD=${MYSQL_ROOT_PASSWORD} \

--env MYSQL_USER=${MYSQL_USER} \

--env MYSQL_PASSWORD=${MYSQL_PASSWORD} \

--env MYSQL_DATABASE=${MYSQL_DATABASE} \

--name ${MYSQL_CONTAINER_NAME} \

--publish 3306:3306 \

mysql:5.7;

Starting a MySQL instanceDocker run

Data ContainerA common practice is to create a data container -- container whose sole purpose is to share data between other container. The main benefit of this approach is tha it provides a handy namespaces for volumenes that can be easily loaded using --volumes-from command.

$ docker run --name dbdata mysql echo “Data-only container for MySQL”

$ docker run -d --volumenes-from dbdata --name db1 mysql
