Deploying WordPress with Docker Compose on CentOS 7

Docker Compose is a powerful tool for defining and running multi-container Docker applications. In this article, we will explore how to deploy a WordPress application using Docker Compose on CentOS 7.

The first step is to create a directory for our WordPress site:

```

mkdir wordpress-site

```

Next, we need to pull the latest WordPress and MySQL container images from Docker Hub:

```

docker pull wordpress

```

Now, let's create a `docker-compose.yml` file in our `wordpress-site` directory. This file will define the services for our applications and container images.

Here is an example of what the `docker-compose.yml` file might look like:

```

version: '3'

services:

db:

image: mysql:latest

environment:

MYSQL_ROOT_PASSWORD: your_root_password

MYSQL_DATABASE: wordpress

MYSQL_USER: wordpress

MYSQL_PASSWORD: your_wordpress_password

wordpress:

image: wordpress:latest

ports:

- '80:80'

depends_on:

db:

condition: service_healthy

environment:

WORDPRESS_DB_HOST: db

WORDPRESS_DB_USER: wordpress

WORDPRESS_DB_PASSWORD: your_wordpress_password

```

This `docker-compose.yml` file defines two services: `db` and `wordpress`. The `db` service uses the latest MySQL image, and the `wordpress` service uses the latest WordPress image.

To deploy our containers with Docker Compose, we need to navigate to the directory containing our `docker-compose.yml` file:

```

cd wordpress-site

```

Then, we can start our containers using the following command:

```

docker-compose up -d

```

This will start our containers in detached mode. To verify that everything is working as expected, we can check the status of our containers using:

```

docker-compose ps

```

If everything is running smoothly, we should see output similar to this:

```

Name Command State Ports

----------------------------------------------------------------------------wordpress-site_db_1 docker-entrypoint.sh mysql Running

wordpress-site_wordpress_1 /app/hooks/start Running 0.0.0.0:80->80/tcp

```

Finally, we can access our WordPress site by navigating to `http://localhost` in a web browser.

That's it! We have successfully deployed a WordPress application using Docker Compose on CentOS 7. This is just the beginning of what you can do with Docker Compose - feel free to experiment and learn more about its capabilities.
