Docker is an innovative technology that developed in a short period (about two years) and is in great demand in modern IT industries today.

Docker Raspberry Pi is a tool for developing, deploying and executing applications using containers. It is lightweight and most effective as compared to virtual machines. In this article, we will understand how this Raspberry Pi technology is different and innovative in terms of other competitive technologies.

Installing Docker Raspberry Pi

For installing Docker using Raspberry Pi, we need to follow the below steps.

  • Keep your system upgraded and updated.
  • Install the package and download the installation script.
  • Give access to a non-root developer to perform Docker commands. 
  • Confirm the installation and check the Docker version. It should be updated.
  • Check the Setup and Test by executing a “hello-world” using the container.

Let us now understand these steps in detail.

Step 1:

Upgrade and Update 

In this step, keep upgrading and updating your system and install the most advanced software version.

Run this command "sudo apt-get update && sudo apt-get upgrade" as shown in the below screenshot.


Step 2:

Download the right script and install Docker on the Raspberry Pi environment. 

Push this below installation script.

curl -fsSL -o

Run the script with the help of the below command:

sudo sh

This establishes the expected packages on the Raspbian Linux administration environment.


Here is the running output of the Docker version as per the above command.

Step 3:

Append a non-root user on the Docker group

As per the Raspberry Pi process, whichever user has the administrative rights whom we can consider as root user can execute containers. For example, if a case user is not logged in to the admin root, then they should use the sudo prefix.

We can also add the non-root users to the Docker group, which will enable running the executed docker commands.

Here is the syntax for adding users to the Docker group:

sudo usermod -aG docker [user_name]

We can consider it the default user for adding the Pi user in Raspbian.

Refer to the below command:

 sudo usermod -aG docker Pi

We need to log out of the system to check the output process.

Step 4:

For checking the Updated Docker Version and info details on your Raspberry Pi, refer to the below command.

docker version

The below output screenshot will show the docker version with all the relevant details.

For getting the system-wide details, which involve the list of containers, kernel version, and docker images, run this below command.

docker info

Step 5:

Execute/run the sample Hello World Container. Here we need to configure and set up this below command.

docker run hello-world

After running the above command, it will contact the Docker daemon and pull the “hello-world” image. 

The output will show the “installation appears to be working correctly” message.


Docker Raspberry Pi 4

  • Raspberry Pi 4 can work as a low-cost Docker resolution for application development and various responsibilities. It has the latest 8GB version.
  • A Raspberry Pi 4 is a single-board processor. To connect Docker on your Raspberry Pi 4, we need the following:
  • A Raspberry Pi 4 Type-C power accumulation.
  • A microSD card has a minimum of 32GB storage space, including the Raspberry Pi OS image on it.
  • Internet connectivity using the Raspberry Pi 4.
  • A laptop or computer for VNC remote desktop accessibility using SSH way to the Raspberry Pi 4.

Installing Docker Raspberry Pi 4 

Below is the command for updating Raspberry Pi OS.

$ sudo apt update


After running the command, it will show the below output.


Run the below command to update all the Raspberry Pi OS environment packages.

 $ sudo apt upgrade




Raspberry Pi 4 Docker

Raspberry Pi 4 can be applied to build a private cloud resolution with Ansible and Docker, which are great tools used by various large-scale cloud systems that automate the tasks, configure them, and enable containerization for the applications.

After booting your system, the following commands can implement the most advanced Rasbian updates.

$ sudo apt update

$ sudo apt dist-upgrade

To define the hostname, we need to add two files as per the below command.

$ sudo nano /etc/hostname

$ sudo nano /etc/hosts
