How To Install Docker on Debian 9 Stretch

Install Docker on Debian 9 Stretch

In this tutorial, we will show you how to install Docker on Debian 9 Stretch. For those of you who didn’t know, Docker is an open-source project that automates the deployment of the application inside the software container. The container allows the developer to package up all project resources such as libraries, dependencies, assets, etc. Docker is written in a Go Programming language and is developed by Dot cloud. It is basically a container engine that uses the Linux Kernel features like namespaces and control groups to create containers on top of an operating system and automates the application deployment on the container.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of Docker’s latest version on a Debian 9 (Stretch) server.


  • A server running one of the following operating systems: Debian 9 (Stretch).
  • It’s recommended that you use a fresh OS install to prevent any potential issues.
  • SSH access to the server (or just open Terminal if you’re on a desktop).
  • A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install Docker on Debian 9 Stretch

Step 1. Before we install any software, it’s important to make sure your system is up to date by running the following apt-get commands in the terminal:

apt-get update
apt-get upgrade

Step 2. Installing Docker on Debian 9 server.

First, install some additional packages prior to Docker installation:

apt-get install apt-transport-https ca-certificates curl software-properties-common

Add the GPG key for the Docker repository on your system:

sudo apt-key add gpg

Next, add the docker repository to your Debian Stretch machine with the command:

echo "deb [arch=amd64] $(lsb_release -cs) stable" | sudo tee -a /etc/apt/sources.list.d/docker.list

Update the apt database and install Docker:

apt-get install docker-ce

Once that is done, start and enable docker to run on bootup:

systemctl start docker
systemctl enable docker

Verify Docker installation:

### docker --version
Docker version 1.11.0, build 4dc5990

Step 3. Deploying your First Docker Image, “Hello World!”.

To be sure that we successfully installed Docker, we can start the all-time classic “hello-world” image:

docker run hello-world

If you see this message, then it’s working correctly:

Hello from Docker.
This message shows that your installation appears to be working correctly.

Congratulations! You have successfully installed Docker. Thanks for using this tutorial for installing Docker on Debian 9 Stretch server. For additional help or useful information, we recommend you check the official Docker website.
