In the following, we give examples for Debian-based operating systems using the apt package manager. If you are using an OS with a different package manager (for example, Fedora Linux with the yum package manager), please adapt the commands shown to your specific system.

First, please ensure that your system is up-to-date and has the latest OS kernel installed.

sudo apt-get update
sudo apt-get upgrade

Next, install the Docker runtime, as well has the docker-compose stack. Create a file install-docker.sh with the following contents:

#!/bin/bash

# This file is install-docker.sh

# Set terminal output
set -xe

# Install Docker
curl -fsSL https://get.docker.com -o get-docker.sh
sudo sh get-docker.sh

# Install docker-compose 1.26.2
sudo curl \
 -L "https://github.com/docker/compose/releases/download/1.26.2/docker-compose-$(uname -s)-$(uname -m)" \
 -o /usr/local/bin/docker-compose

sudo chmod +x /usr/local/bin/docker-compose

Then set this file as executable and run it to add the docker and docker-compose commands to your system:

chmod a+x install-docker.sh
./install-docker.sh

The following commands should run successfully and print the version numbers for docker and docker-compose:

docker -v
docker-compose -v

Finally, install the native WireGuard® network protocol and kernel extensions for your OS:

sudo apt-get update
sudo apt-get install -y wireguard wireguard-dkms wireguard-tools

The following command should run successfully and print the version number for wireguard-tools:

wg -v

Now it is time to reboot the host:

sudo reboot now
