install docker on raspberry pi

Installing Docker on a Raspberry Pi is straightforward and convenient. Here is a step-by-step guide that will walk you through the process.

Prerequisites

Before starting, ensure your Raspberry Pi is running a recent version of the Raspbian operating system and is connected to the internet.

Step 1: Update your System

Open a terminal window and input the following commands:

sudo apt-get update
sudo apt-get upgrade

This will ensure that your system is up to date.

Step 2: Download and Install Docker

To download Docker, type the following command:

curl -fsSL https://get.docker.com -o get-docker.sh

After the Docker script has been downloaded, you can install Docker by typing:

sudo sh get-docker.sh

Wait for the process to complete, Docker should now be installed on your Raspberry Pi.

Step 3: Add Permission to Pi User to Run Docker Commands

To avoid inputting sudo each time you run the Docker command, add the pi user to the Docker group by typing:

sudo usermod -aG docker pi

Step 4: Test Docker Installation

To confirm your installation, you can run a simple hello-world container. Type:

docker run hello-world

You should see a message that your Docker installation appears to be working correctly.

Step 5: Update Docker

To keep Docker updated, use the standard updating commands:

sudo apt-get update
sudo apt-get upgrade

This will include Docker in the list of packages to be updated.

By following these simple steps, you can easily install Docker onto your Raspberry Pi and start developing your containerized applications. Have fun!
