Docker Compose Tutorial: Installing, Configuring, and Running a WordPress Application

Docker Compose allows managing multi‑container Docker applications via a single configuration file, eliminating the need for shell scripts.

System environment: Ubuntu 17.04 x64, Docker CE 17.12.0‑ce, Docker Compose 1.18.0.

Installation: download the latest binary with curl and apply executable permission:

curl -L https://github.com/docker/compose/releases/download/1.18.0/docker-compose-$(uname -s)-$(uname -m) -o /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose
docker-compose --version

Uninstall by removing the binary:

rm /usr/local/bin/docker-compose

Example: a WordPress site with a MySQL database. Create project directory and docker‑compose.yml:

mkdir my_wordpress
cd my_wordpress
cat > docker-compose.yml <
Start the services in detached mode:
docker-compose up -d
Verify that the containers are pulling images and running, then access the site at
http://localhost:8000
.
Additional commands to inspect containers, images, and to enter the MySQL container for data verification are provided, demonstrating volume mounting and persistence.
