Install and use Docker Compose Ubuntu 22.04

Install and use Docker Compose Ubuntu 22.04 2 very simple steps..

Introduce

Docker compose is a tool used 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. Using is also quite simple according to the steps:

• Declare 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, I will show you how to install Docker compose and create a new application using Docker compose on Ubuntu 22.04.

DNecessary conditions before installation Docker compose

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

Installation Instructions

Step 1: Install Docker Compose

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
    

• The file permissions have just re-downloaded

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

• Test after installation

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

Step 2: Using 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 
    

• Create a YAML file, for the basic example I will create a yaml file for hello world.

sudo nano docker-compose.yml
    

Add 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.

And here is the result after running

And so the hello-world image is taken from Docker Hub and docker-compose creates a container, attaches it and runs the program.

• To view all existing containers, use the command:
