How To Install Docker Compose on Fedora 38

In this tutorial, we will show you how to install Docker Compose on Fedora 38. Docker Compose simplifies the deployment of complex applications by allowing you to define multi-container environments in a single file. It automates the process of creating and starting containers, making it a must-have tool for developers and DevOps professionals.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the Docker Compose on a Fedora 38.

Prerequisites

• A server running one of the following operating systems: Fedora 38.
• It’s recommended that you use a fresh OS install to prevent any potential issues.
• SSH access to the server (or just open Terminal if you’re on a desktop).
• An active internet connection. You’ll need an internet connection to download the necessary packages and dependencies for Docker Compose.
• A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install Docker Compose on Fedora 38

Step 1. Before proceeding, it’s essential to update your system’s package list. Use the following commands:

sudo dnf clean all
sudo dnf update

Step 2. Installing Docker.

We’ll begin by installing the Docker repository. This repository contains the Docker Engine packages:

sudo dnf config-manager --add-repo=https://download.docker.com/linux/fedora/docker-ce.repo

Once the repository is added, proceed to install the Docker Engine:

sudo dnf install docker-ce

Now that Docker is installed, start the service and enable it to start on boot:

sudo systemctl start docker
sudo systemctl enable docker

To ensure that Docker is correctly installed and running, run the following command:

sudo docker --version

Step 3. Installing Docker Compose on Fedora 38.

Docker Compose allows you to define and run multi-container applications with ease. It uses a simple YAML file to configure the services, networks, and volumes of your application. We will need the Docker Compose binary. You can check the latest release on the Docker Compose GitHub page:

sudo curl -L "https://github.com/docker/compose/releases/latest/download/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

After downloading, make the binary executable:

sudo chmod +x /usr/local/bin/docker-compose

Move the Docker Compose binary to a directory included in your system’s PATH. This ensures that you can execute it from any location:

sudo mv /usr/local/bin/docker-compose /usr/bin/docker-compose

To confirm the successful installation of Docker Compose, check the version:

docker-compose --version

This should display the installed Docker Compose version.

Run the following command to verify the installation:

docker-compose

Step 4. Using Docker Compose.

• A. Compose Files and YAML Syntax

Docker Compose relies on YAML files for configuration. These files define the services, networks, and volumes required for your application.

• B. Defining Services in a Compose File

Create a docker-compose.yml file in your project directory to define your services. For instance, a simple Compose file for a web application might look like this:

version: '3'
services:
web:
image: nginx:alpine
db:
image: postgres:alpine

• C. Building and Starting Containers

To create and start the containers specified in your Compose file, navigate to the directory containing the file and run:

docker-compose up

• D. Managing Multi-Container Applications

Docker Compose simplifies managing multi-container applications. Use commands like docker-compose start, docker-compose stop, and docker-compose restart to manage your services effectively.

• E. Networking and Volumes with Docker Compose

Docker Compose automatically handles networking between containers and allows you to specify volumes for data persistence.
