![]() This service uses the nginx:alpine image and sets up a port redirection with the ports directive. In your case, you have a single service called web. You then have the services block, where you set up the services that are part of this environment. This will tell Docker Compose which configuration version you’re using. The docker-compose.yml file typically starts off with the version definition. To verify that the installation was successful, you can run:ĭocker-compose.yml version : '3.7' services : web : image : nginx :alpine Now you can install Docker Compose, which is a plugin for Docker: While there is no Rocky Linux specific repository from Docker, Rocky Linux is based upon CentOS and can use the same repository. Next, add the official Docker repository if you didn’t do so during your Docker install: To make sure you obtain the most updated stable version of Docker Compose, you’ll download this software from the official Docker repository.įirst, let’s update the package database: Docker installed on your server or local machine, following Steps 1 and 2 of How To Install and Use Docker on Rocky Linux 9.To set these up, please refer to our Initial Server Setup Guide for Rocky Linux 9. If you’re using a remote server, it’s advisable to have an active firewall installed. Access to a Rocky Linux 9 local machine or development server as a non-root user with sudo privileges.In this guide, you’ll demonstrate how to install Docker Compose on a Rocky Linux 9 server and how to get started using this tool. It uses service definitions to build fully customizable environments with multiple containers that can share networks and data volumes. Docker Compose is a tool that allows you to run multi-container application environments based on definitions set in a YAML file. This allows developers to break down an application environment into multiple isolated services.įor applications depending on several services, orchestrating all the containers to start up, communicate, and shut down together can quickly become unwieldy. While containers are similar to virtual machines in certain ways, they are more lightweight and resource-friendly. ![]() Docker simplifies the process of managing application processes in containers.
