Running Multiple Wordpress Instances In Docker

When running multiple instances of WordPress in docker, this will be very helpful.

docker run -e MYSQL_ROOT_PASSWORD='strongpassword' \ -e MYSQL_USER=wpuser -e MYSQL_PASSWORD='strongpassword' -e MYSQL_DATABASE=website_db \ -v /var/www/website/database:/var/lib/mysql --name website_db \ -d --restart always mariadb

You must make sure to run mysql or mariadb container first. Because it will in on the network created by docker before you create wordpress instance

docker run -e WORDPRESS_DB_HOST=website_db -e WORDPRESS_DB_USER=wpuser \ -e WORDPRESS_DB_PASSWORD='strongpassword' -e WORDPRESS_DB_NAME=website_db \ -p 8081:80 -v /var/www/website/html:/var/www/html --name website_wordpress \ --link [db container name]:mysql -d --restart always wordpress

you can certainly access volumes from /var. And also use docker exec to add dbdump files.
