How to Install Pomerium on Void Linux

Pomerium is an open-source identity-aware access proxy that is designed to offer secure authentication and authorization for modern web applications. This tutorial will guide you through the process of installing Pomerium on Void Linux.

Prerequisites

Before you start, ensure that you have the following prerequisites:

A user account with sudo privileges.
Docker installed on your system.

Installation

The installation of Pomerium involves the following steps:

Install Certbot and create SSL certificates

To run Pomerium properly, you need to have a valid SSL certificate. Certbot allows you to obtain an SSL certificate for your domain. To install Certbot on Void Linux, execute the following command:
```
sudo xbps-install certbot
```
After the installation completes, run the following command to obtain the SSL certificate:
```
sudo certbot certonly --standalone -d example.com
```
Replace example.com with your domain name. Follow the on-screen instructions to generate the SSL Certificate.
Install Pomerium

Once you have the SSL certificate, run the following command to install Pomerium:
```
sudo docker run -it -p 443:443 -v /etc/letsencrypt/live/example.com/:/etc/certs/ pomerium/pomerium:v0.17.0
```
Replace example.com with your domain name. This command will download the latest Pomerium image from Docker Hub and start it with a mounted SSL certificate.

Note: You can replace v0.17.0 with the version of Pomerium that you want to install.
Configure Pomerium

Pomerium is now installed on your system, but it needs to be configured before you can use it. The configuration file for Pomerium is located at /etc/pomerium/config.yaml.

Create this file and add the following contents:
```
route:
  from: "https://example.com"
  to: "http://localhost:8080"
```
Replace example.com with your domain name and localhost:8080 with the address of the server you want to redirect traffic to.

Save the changes to the configuration file and exit the text editor.
Start Pomerium

To start Pomerium, execute the following command:
```
sudo docker run -it -p 443:443 -v /etc/letsencrypt/live/example.com/:/etc/certs/ -v /etc/pomerium:/etc/pomerium pomerium/pomerium:v0.17.0 -config /etc/pomerium/config.yaml
```
Replace example.com with your domain name.

Congratulations! Pomerium is now running on your system and redirecting traffic from your domain to the specified server.
