Ubuntu 24.04 - Install Docker

#Introduction

In this article, we will learn how to install Docker on Ubuntu 24.04. Docker is a containerization platform that allows you to package and run applications in containers, which are lightweight, portable, and self-sufficient.

#Add Docker Repository

Before installing Docker, we need to add the Docker repository to our system. This can be done by running the following command:

bash

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
 
echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

#Install Docker Package

After adding the Docker repository, we can install the Docker package by running the following command:

bash

sudo apt update && apt-cache policy docker-ce && sudo apt install docker-ce
 
sudo systemctl status docker

#Add Current User to Docker Group

After installing Docker, we need to add the current user to the Docker group to allow the user to run Docker commands without using sudo. This can be done by running the following command:

bash

sudo usermod -aG docker ${USER} && su - ${USER}

#Install Docker Compose

After installing Docker, we can install Docker Compose by running the following command:

bash

sudo apt update && sudo apt install docker-ce-cli containerd.io docker-compose-plugin docker-compose
 
docker compose version

#Docker Command Cheatsheet

There are several Docker commands that we can use to manage and run our containers. Here are some of the most Docker commands that we can use:

#List Container

docker ps -a

#Enter Into Container Interactive Shell

Change container_name with actual container name

bash

docker exec -it container_name /bin/bash
