When i tried to fetch data of mysql from env, iam getting FIND parament is not correct
================================================================
application is to create a database server:
docker rm -f (docker ps -qa)
$ docker run -d --name mariadb -e MYSQL_ROOT_PASSWORD=wordpress -e MYSQL_DATABASE=wordpress -e MYSQL_USER=wordpress -e MYSQL_PASSWORD=password mariadb

The next step is to run a WordPress container. In that command, we will link the wordpress container with the mariadb container:
$ docker run -d --name wordpress --link mariadb:mysql -p 8080:80 wordpress

Let’s check container environments with the docker exec command:
$ docker exec -it wordpress env|grep -i mysql
MYSQL_PORT=tcp://172.17.0.2:3306
MYSQL_PORT_3306_TCP=tcp://172.17.0.2:3306
