Update your Pi.

apt-get update
apt-get upgrade

Start the Docker service.

systemctl enable docker.service
systemctl start docker.service

Verify that Docker is installed and running.

docker info
docker ps

install docker-compose

apt-get install libffi-dev libssl-dev
apt install python3-dev
apt-get install -y python3 python3-pip

python3 and pip3 are installed, we can install Docker-Compose using the following command:

pip3 install docker-compose

check it

docker-compose --version

docker-compose ⇒ 1.27.4
