Install and use Docker Compose on Ubuntu 22.04

How to install and use Docker Compose on Ubuntu 22.04 with 2 steps.

Introduction

Docker compose is a tool to define and run multi-containers for Docker applications. With compose, you use the YAML file to configure the services for your application. Then use the command to create and run from those configs. The steps to use are also quite simple, as follows:

• Declare the app’s environment in Dockerfile.
• Declare the services needed to run the application in the docker-compose.yml file.
• Run docker-compose up to start and run the app.

In this tutorial, AZDIGI will show you how to install Docker compose and create a new application using Docker compose on Ubuntu 22.04.

Prerequisites before installing Docker compose

1. You must have SSH access
2. The server must have Docker pre-installed.

Implementation Guide

Step 1: Install Docker Compose

• To install the latest version of Docker Compose from the GitHub repository, use the following command:

sudo curl -L https://github.com/docker/compose/releases/download/v2.5.0/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
    

• Permissions for the downloaded file

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

• Check results after installation

docker-compose --version
    

So Docker Compose has been successfully installed and you can start running containers.

Step 2: How to use Docker Compose

Docker Compose allows you to use YAML files to define multiple container applications. With the YAML file, you can run, build and configure all the containers.

• Create a project folder and move into that project folder, for example:

mkdir docker-project 
cd docker-project 
    

• Next, you need to create a YAML file. For example, I will create a yaml file for hello world.

sudo nano docker-compose.yml
    

Add the below content to the created file

version: '3.9'
services:
   hello-world:
      image:
         hello-world:latest

You can now execute the following command to pull the hello word image from Docker Hub.

docker-compose up
    

And here is the result after running the command:

So the hello-world image is taken from Docker Hub and docker-compose creates an attached container and runs the program.

• To view all existing containers, use the command:

docker ps -a
