Tengo una Raspberry PI 4 de 8 GB y estoy haciendo un servidor para que contenga contenedores docker.  En este post voy a estar mostrando como tener docker en nuestra distro Raspberry Pi OS

Obs:

•  Se utiliza Raspberry Pi OS (Debian Buster) de 64 bits.

Entramos a la terminal y tecleamos lo siguiente:

sudo apt update
sudo apt upgrade
sudo apt install raspberrypi-kernel raspberrypi-kernel-headers
curl -sSL https://get.docker.com | sh

Para que docker se inicie cuando se encienda el equipo:

sudo systemctl enable docker.service
