How to install Cabot on NixOS

Cabot is an open-source self-hosted monitoring platform. In this tutorial, we're going to install Cabot on a NixOS latest server.

Prerequisites

• NixOS server
• Root access to the server

Step 1: Install Required Packages

Firstly, update the package list and install the required packages.

sudo nix-channel --update
sudo nix-env -i git python37

Step 2: Install Cabot

The next step is to install Cabot using git. Clone Cabot's git repository into /opt/.

sudo git clone https://github.com/arachnys/cabot.git /opt/cabot

Step 3: Install Dependencies

Now we need to install the dependencies required by Cabot. The best way to do this is by using a virtual environment. Firstly, install virtualenv package.

sudo nix-env -i python37Packages.virtualenv

Create a virtual environment in our Cabot directory.

cd /opt/cabot
virtualenv venv

Activate your virtual environment.

source venv/bin/activate

Finally, install the dependencies by running the following command.

pip install -r requirements.txt

Step 4: Configure Cabot

sudo cp conf/production.env.example conf/production.env
sudo sed -i "s/DEBUG=false/DEBUG=true/g" conf/production.env

This will create a new configuration file named production.env with DEBUG set to true.

Step 5: Start Cabot

To start Cabot, activate your virtual environment and run the following command.

source venv/bin/activate
PYTHONPATH=. python3 bin/cabot run

Step 6: Access Cabot
