Creating A Docker Compose File

Setting up your WordPress site with Docker involves creating a Docker Compose file. This file will define the services, networks, and volumes for your WordPress site. Let’s break down how to create this file step-by-step.

Understanding Docker Compose

Docker Compose is a tool for defining and running multi-container Docker applications. With a single command, you can create and start all the services from your configuration.

In a Docker Compose file, you specify the services you need. This can include a web server, database, and other components. Docker Compose allows you to manage everything in one place.

Each service is defined with a set of parameters. These parameters include the image to use, ports to expose, and volumes to mount.

Sample Docker Compose File

Below is an example of a Docker Compose file for a WordPress setup. This file includes WordPress and MySQL services.


version: '3.7'

services:
  wordpress:
    image: wordpress:latest
    ports:
      - "8000:80"
    environment:
      WORDPRESS_DB_HOST: db
      WORDPRESS_DB_USER: exampleuser
      WORDPRESS_DB_PASSWORD: examplepass
      WORDPRESS_DB_NAME: exampledb
    volumes:
      - wordpress_data:/var/www/html

  db:
    image: mysql:5.7
    environment:
      MYSQL_DATABASE: exampledb
      MYSQL_USER: exampleuser
      MYSQL_PASSWORD: examplepass
      MYSQL_ROOT_PASSWORD: rootpass
    volumes:
      - db_data:/var/lib/mysql

volumes:
  wordpress_data:
  db_data:

The version indicates the version of the Docker Compose file format. The services section defines two services: WordPress and MySQL.

In the wordpress service:

The image used is the latest WordPress image.
Ports are mapped from 8000 on the host to 80 in the container.
Environment variables configure the database connection.
A volume is mounted to persist WordPress data.

In the db service:

The image used is MySQL version 5.7.
Environment variables configure the database user, password, and name.
A volume is mounted to persist MySQL data.

The volumes section defines named volumes for data persistence. These volumes ensure that your data is not lost when containers are recreated.

Launching WordPress Container

Launching your WordPress container using Docker is simple. This tutorial will guide you through the process step by step. You’ll have your WordPress site running in no time.
