In this tutorial, I will walk you through how to install Docker and Docker Compose on Ubuntu and Debian.
Installation of Docker and docker-compose from the official repositories
Docker and docker-compose are part of the official repositories of both distributions (Ubuntu and Debian), so just run the two commands below:
sudo apt install docker.io
sudo apt install docker-compose
The problem as often with official repositories is the update time to the latest versions which can be long, so I will explain how to install Docker and docker-compose from the Docker repository in order to have the latest version .
Installing Docker and docker-compose from the Docker repository
Make sure you have your distribution up to date:
sudo apt update sudo apt upgrade
sudo apt-get install ca-certificates curl gnupg lsb-release -y
Add repository GPG key:
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
Update package list:
sudo apt update
sudo apt-get install docker-ce docker-ce-cli containerd.io -y
The Docker containerization engine is installed.
We will now move on to installing docker-compose which is optional to use containers.
The main advantage of using docker-compose is to use configuration files to launch the containers, which allows for easier administration and configuration.
To install docker-compose, we will retrieve the file directly from the Github repository :
sudo curl -L "https://github.com/docker/compose/releases/download/v2.7.0/docker-compose-linux-x86_64" -o /usr/local/bin/docker-compose
Now we make the docker-compose file executable:
sudo chmod +x /usr/local/bin/docker-compose
It’s finished, Docker and docker-compose are installed.
To save time, you can use this script:
All you have to do is deploy your containers.
Here you will find several applications ready to be used with docker-compose.
