How to Install Tuber on NixOS Latest

Tuber is an open-source self-hosted video chat platform that allows individuals and organizations to securely communicate with others. This tutorial will guide you through the process of installing Tuber on NixOS Latest.

Prerequisites

Before installing Tuber on NixOS Latest, make sure that you have the following prerequisites:

• A running instance of NixOS Latest.
• Sudo access or root privileges on that instance.
• Basic knowledge of the command-line interface.

Step 1: Enable the NixOS Unstable Channel

As Tuber is not available in the stable NixOS repository, we need to enable the NixOS unstable channel to install it. Run the following command to enable the NixOS unstable channel:

$ sudo nix-channel --add https://nixos.org/channels/nixos-unstable nixos
$ sudo nix-channel --update

Step 2: Install Required Dependencies

Tuber requires the following dependencies to be installed on your NixOS instance:

• Git
• Nginx
• OpenSSL
• SQLite

Run the following command to install these dependencies:

$ sudo nix-env -iA \
    nixos.git \
    nixos.nginx \
    nixos.openssl \
    sqlite

Step 3: Clone the Tuber Repository

Clone the Tuber repository from the official Trail of Bits Github account:

$ sudo git clone https://github.com/trailofbits/tuber.git /var/www/tuber

Step 4: Configure Nginx

Create a new Nginx configuration file, /etc/nginx/sites-available/tuber, by running the following command:

$ sudo nano /etc/nginx/sites-available/tuber

Paste the following configuration into the file:

server {
    listen 0.0.0.0:443 ssl;
    server_name your_domain.com;

    ssl_certificate /etc/ssl/server.pem;
    ssl_certificate_key /etc/ssl/server-key.pem;

    location / {
        proxy_pass http://127.0.0.1:3000;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_set_header Host $host;
    }
}

Make sure to replace the server_name value with your own domain name. Save the file.

Make a symlink of the Nginx configuration file:

$ sudo ln -s /etc/nginx/sites-available/tuber /etc/nginx/sites-enabled/tuber

Reload Nginx to apply the changes:

$ sudo systemctl reload nginx

Step 5: Generate SSL Certificates

Generate Let's Encrypt SSL certificates by running the following command:

$ sudo certbot certonly --standalone -d your_domain.com

Follow the on-screen prompts and provide the required details. Once the process is complete, the SSL certificates will be generated and saved to /etc/letsencrypt/live/your_domain.com.

Step 6: Update Tuber Configuration

Update the Tuber configuration by editing the .env.production file located in the /var/www/tuber folder:

$ sudo nano /var/www/tuber/.env.production

Update the following values in the file:

DATABASE_URL=/var/www/tuber/db.sqlite
ROOT_URL=https://your_domain.com
PORT=3000

Make sure to replace your_domain.com with your own domain name. Save the file.

Step 7: Build and Start Tuber

Run the following command to build and start Tuber:

$ sudo nix-build -A app && \
    sudo /var/www/tuber/result/bin/tuber

Your Tuber instance is now up and running! Access Tuber by visiting https://your_domain.com in your web browser.
