"What is Docker Compose?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 is a tool for defining and managing multi-container Docker applications using a declarative docker-compose.yml file. It replaces multiple docker run commands by describing services, networks, and volumes in one place. A single command can spin up the entire application stack, allowing coordinated startup and management of related containers. Installation of Docker Compose is required before use. A simple Compose file can begin with a single service. The services key serves as the root where all containers (services) that constitute the application are defined.
