"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."
"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 provides a declarative way to define and manage multi-container Docker applications in a single docker-compose.yml file. Applications, networks, and volumes are described as services instead of running many separate docker run commands. A single command can start the entire application stack and manage relationships between services. Docker Compose requires installation before use. Beginners typically begin with a simple Compose file containing one service and use the services key as the root where each container configuration is defined. Compose simplifies orchestration for development and local testing of multi-container setups.
