How to Install Docker Compose on Ubuntu: A Complete Guide

Introduction

Docker Compose is an essential tool for developers working with Docker containers. It allows you to define and run multi-container Docker applications with ease. If you're using Ubuntu, installing Docker Compose is a straightforward process. This guide will walk you through each step of installing Docker Compose on your Ubuntu system, enabling you to get your containerized applications up and running quickly.

Prerequisites

Before installing Docker Compose, ensure you have:

• A machine running Ubuntu (we recommend using the latest LTS version).
• Docker installed on your Ubuntu system. If you haven't installed Docker yet, refer to our guide on How to Install Docker on Ubuntu.

Step 1: Download Docker Compose

First, download the latest version of Docker Compose. You can find the current release version on the Docker Compose GitHub repository. Use curl to download it into the /usr/local/bin/docker-compose directory, making it executable:

sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

Step 2: Set Permissions

After downloading, set the correct permissions to make the Docker Compose binary executable:

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

Step 3: Verify Installation

To ensure Docker Compose was installed successfully, run:

docker-compose --version

This command will display the Docker Compose version, confirming the installation.

Step 4: Getting Started with Docker Compose

With Docker Compose installed, you're ready to start using it to manage your containerized applications. Create a docker-compose.yml file in your project directory and define your application's services, networks, and volumes. Here's a simple example to get you started:

version: '3'
services:
  web:
    image: nginx
    ports:
      - "80:80"

Run docker-compose up to start your application.

Conclusion

Installing Docker Compose on Ubuntu is a simple process that opens up a world of possibilities for managing multi-container applications. With Docker Compose, you can easily configure, run, and scale your applications in a Docker environment. For more advanced Docker Compose functionalities, explore the official Docker documentation.

As you embark on deploying and scaling your containerized applications, consider the network performance and global reachability of your services. Docker Compose efficiently manages your applications' containerization, but the real test comes when users across the globe access your services. This is where Akmatori - a Globally Distributed TCP/UDP Balancer becomes invaluable.

Akmatori enhances your deployments by ensuring that your Dockerized applications are delivered with optimal performance, regardless of the users' location. By integrating Akmatori into your deployment strategy, you leverage smart routing and load balancing to reduce latency, prevent downtime, and secure your applications against network anomalies.
