How to Install WordPress in Docker

Using the official WordPress Docker image is a straightforward process. Here's a step-by-step guide on how to use it:

Install Docker on your machine if you haven't already. You can download Docker from the official Docker website.
Open a terminal window and create a new directory for your WordPress installation. For example, you can use the following command:
```
 bashCopy codemkdir ~/wordpress-docker
```
Navigate to the directory that you just created using the following command:
```
 bashCopy codecd ~/wordpress-docker
```
Create a new file called docker-compose.yml using the following command:
```
 bashCopy codetouch docker-compose.yml
```

Open the docker-compose.yml file in a text editor and paste the following contents:

 yamlCopy codeversion: '3.7'

 services:
   db:
     image: mysql:5.7
     volumes:
       - db_data:/var/lib/mysql
     restart: always
     environment:
       MYSQL_ROOT_PASSWORD: somewordpress
       MYSQL_DATABASE: wordpress
       MYSQL_USER: wordpress
       MYSQL_PASSWORD: wordpress

   wordpress:
     depends_on:
       - db
     image: wordpress:latest
     volumes:
       - wordpress_data:/var/www/html
     ports:
       - "8000:80"
     restart: always
     environment:
       WORDPRESS_DB_HOST: db:3306
       WORDPRESS_DB_USER: wordpress
       WORDPRESS_DB_PASSWORD: wordpress
       WORDPRESS_DB_NAME: wordpress

 volumes:
   db_data:
   wordpress_data:

This YAML file defines two services, one for the MySQL database and another for WordPress.

Save and close the docker-compose.yml file.
In the terminal, navigate to the ~/wordpress-docker directory and run the following command to start the Docker containers:
```
 Copy codedocker-compose up -d
```
This command will start the containers in the background (-d flag).
After a few seconds, the WordPress site should be up and running. Open a web browser and go to http://localhost:8000 to access your new WordPress site.

That's it! You have now successfully set up WordPress using the official Docker image.
