Installing WordPress with Docker

1. Firstly, let us pull WordPress docker using the following command:

   docker pull wordpress

2. Before we proceed further, let us learn the environment variables and docker parameters below:
   -e WORDPRESS_DB_PASSWORD= Set the same database password here.
   –name wordpress – Gives the container a name.
   –link wordpressdb:mysql – Links the WordPress container with the MariaDB container so that the applications can interact. You should have created “wordpressdb” when you install MariaDB docker container
   -p 80:80 – Tells Docker to pass connections from your server’s HTTP port to the containers internal port 80.
   -v “$PWD/html”:/var/www/html – Sets the WordPress files accessible from outside the container. The volume files will remain even if the container was removed.
   -d – Makes the container run on background
   wordpress – Tells Docker what to install. Uses the package downloaded earlier with the docker pull wordpress -command.
3. We can now execute the following command to complete the installation with docker:
   docker run -e WORDPRESS_DB_USER=root -e WORDPRESS_DB_PASSWORD=password-here –name wordpress –link wordpressdb:mysql -p 80:80 -v “$PWD/html”:/var/www/html -d wordpress
4. Finally, you may complete WordPress installation by using your browser to visit your server and complete the web-based wizard.
