Install gluetun as vpn network service with docker-compose

Gluetun VPN is a VPN (Virtual Private Network) service that helps protect the privacy and security of a user's Internet connection

Intro

Gluetun VPN uses the OpenVPN protocol to create a secure and encrypted connection between the user's computer and the Gluetun VPN server.

The advantages of Gluetun VPN are numerous. First, it hides the user's IP address, which prevents websites, advertisers, and third parties from tracking and collecting user information. Moreover, the end-to-end encryption provided by Gluetun VPN ensures that all data sent and received by the user is secure and private.

Additionally, Gluetun VPN helps bypass geo-restrictions by giving the user access to websites and services that might otherwise be blocked in their region. For example, if a user is in a country where certain sites are blocked, he can use Gluetun VPN to connect to a server located in a country where these sites are available.

Finally, Gluetun VPN is easy to use and configure with tools like Docker and Compose, making it accessible to users of all technical skill levels.

Setup

You need to create a docker-compose.yml file in a folder of your choice.In this file, you need to define the services you want to run using Gluetun as VPN service. Here is an example of a basic configuration file:

version: '3'
services:
  gluetun:
    image: qmcgaw/gluetun
    volumes:
      - gluetun:/gluetun
    cap_add:
      - NET_ADMIN
    devices:
      - /dev/net/tun:/dev/net/tun
  myapp:
    image: myapp:latest
    network_mode: "service:gluetun"

Here you have two services: gluetun and myapp. The gluetun service is configured to run the Gluetun container with the necessary options to manage VPN connections.The myapp service is configured to use the gluetun service's network via the network_mode: "service:gluetun" option, which means that all outgoing network connections from the myapp container go through the VPN managed by the gluetun container.example configuration using gluetun VPN and amule
