   01. Log into the Linux device    02. Execute the following commands in a terminal:

update software repositories

sudo apt update

install necessary packages for https apt calls

sudo apt install apt-transport-https ca-certificates curl gnupg-agent software-properties-common

add docker GPG key

curl -fsSL https://download.docker.com/linux/raspbian/gpg | sudo apt-key add -

add docker software repository

echo "deb [arch=armhf] https://download.docker.com/linux/raspbian $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker-ce.list

install docker

sudo apt update sudo apt install docker-ce docker-ce-cli containerd.io

start docker service

sudo systemctl start docker

enable docker service on startup

sudo systemctl enable docker

create a docker group

sudo groupadd docker

add the current user to the docker group

sudo usermod -aG docker $USER    03. To run a basic Docker container, run the following command in a terminal: sudo docker run hello-world    04. Docker will download the hello-world container and execute it, displaying following output:          Hello from Docker!          This message shows that your installation appears to be working correctly.          To generate this message, Docker took the following steps:          1. The Docker client contacted the Docker daemon.          2. The Docker daemon pulled the "hello-world" image from the Docker Hub.          (amd64)          3. The Docker daemon created a new container from that image which runs the          executable that produces the output you are currently reading.          4. The Docker daemon streamed that output to the Docker client, which sent it          to your terminal.   Source:  https://docs.docker.com/engine/install/debian/
