Here is how to install Docker on Raspberry Pi in 2026.
Prerequisites
- Raspberry Pi 3, 4, or 5 with at least 2 GB RAM
- 64-bit OS recommended (Raspberry Pi OS or Ubuntu Server)
Install
curl -fsSL https://get.docker.com | sh
sudo usermod -aG docker $USER
newgrp dockerVerify
docker run hello-world
docker compose versionPerformance Tips
Use 64-bit OS for better Docker performance. Increase swap for memory-constrained Pis:
sudo dphys-swapfile swapoff
sudo sed -i 's/CONF_SWAPSIZE=100/CONF_SWAPSIZE=2048/' /etc/dphys-swapfile
sudo dphys-swapfile setup && sudo dphys-swapfile swapon
