README.md

Note

This guide provides a copy-paste-observe list of quick instructional steps to install Docker instantly on a RaspberryPi, assuming it has a Linux-based operating system on it.

Note

Verified on RaspberryPi 4B.

Instructions 📘

Run this command to download Docker’s GPG key and convert it into a format trusted by APT for secure package verification:

curl -fsSL https://download.docker.com/linux/debian/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg

Run this command to add the Docker APT repository for Debian (Bookworm) so your system can install Docker packages from the official source:

echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/debian bookworm stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

Run these commands to update your package index and install Docker Engine along with CLI tools, Buildx, and Compose plugins:

sudo apt update
sudo apt install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin -y

Run these commands to create the Docker user group and add your current user so Docker can be used without sudo:

sudo groupadd docker
sudo gpasswd -a $USER docker

Run this command to reboot your system so that group membership and Docker installation changes take full effect:

sudo reboot

Verify ✔️

Run docker ps below and you should see something similar below in your terminal:

CONTAINER ID   IMAGE                                COMMAND                  CREATED        STATUS                    PORTS                                                   NAMES
