Docker compose workshop

Docker Compose allows defining and running multi-container Docker applications. It uses YAML files to configure the application's services and Docker to run the containers. Compose works by separating the configuration of services (what runs in containers) from the Docker daemon (what runs the containers). This allows defining and sharing common configurations and ensuring services are always deployed together.
