"If you've ever struggled with running multiple docker run commands for a complex application, Docker Compose is your solution. It's a tool that allows you to define and manage multi-container Docker applications using a single, declarative configuration file. Instead of a long list of commands, you describe all your services, networks, and volumes in a docker-compose.yml file. With one command, you can spin up your entire application stack."
"Docker Compose manages multiple containers. Enough theory - let's get our hands dirty. If you don't have Docker Compose installed yet, follow this guide first. We'll start by creating a simple Compose file with a single service. Create a file named docker-compose.yml and paste the following code: services: This is the root key where you define all the containers (services) that make up your application."
Docker Compose simplifies running complex, multi-container Docker applications by letting users declare all services, networks, and volumes in a single YAML file. The docker-compose.yml file uses a top-level services key to list each containerized service that comprises the application. Compose operates declaratively, replacing multiple docker run commands with one compose command that builds and starts the entire stack. Users should ensure Docker Compose is installed before proceeding and can begin by creating a simple compose file with a single service to learn the format.
