sudo apt-get update && sudo apt-get upgradeStep 2: Download and Install Docker on Raspberry Pi
curl -fsSL https://get.docker.com -o get-docker.sh
sudo sh get-docker.shStep 3: Add a Non-Root User to Docker Group
sudo usermod -aG docker [user_name]Step 4: Check Docker Version and Info

sudo apt -y install docker.io
“sudo apt -y install docker.io” installs docker in a very old version -> 18.09
