How to Install Selenoid on NixOS Latest

In this tutorial, we will walk you through the steps required to install Selenoid on the latest version of NixOS. Selenoid is a powerful and lightweight alternative to Selenium for running Selenium tests. It provides better performance, stability, and more features than Selenium.

Prerequisites

Before you begin, make sure you have the following:

• A user account with sudo privileges
• The latest version of NixOS installed on your system

Step 1: Install Docker

Selenoid requires Docker to run, so the first step is to install Docker on your system. Run the following command to install Docker:

sudo nix-env -iA nixos.docker

Once installed, start Docker by running:

sudo systemctl start docker

And enable it at boot using:

sudo systemctl enable docker

Step 2: Install Selenoid

We will be installing Selenoid using the nix-env package manager. Run the following command to install Selenoid:

sudo nix-env -iA selenoid

This will install Selenoid and all of its dependencies.

Step 3: Configure Selenoid

To configure Selenoid, create a configuration file at /etc/selenoid/browsers.json with the following content:

{
  "chrome": {
    "default": "90.0",
    "versions": {
      "90.0": {
        "image": "selenoid/chrome:90.0",
        "port": "4444",
        "tmpfs": {"/tmp": "size=128m"}
      }
    }
  }
}

This configuration will set up the Chrome browser to run on port 4444.

Step 4: Start Selenoid

To start Selenoid, run the following command:

sudo systemctl start selenoid

You can now test Selenoid by accessing http://localhost:4444/status in your browser.
