It is recommended to use Ubuntu or Raspberry Pi OS 64bit to set up this environment, which is quite easy and only requires a single command. When installing, please ensure that your device can smoothly access the internet.

  • Update and upgrade software repository 
sudo apt update

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