Gatus is an open-source application status page powered by Golang. It allows you to monitor your applications, services, and systems in real-time. In this tutorial, we will provide step-by-step instructions on how to install Gatus on Debian Latest.

Prerequisites

Before starting with the installation process, make sure that you have the following prerequisites:

A Debian Latest Server
A non-root user with sudo privileges
A firewall enabled on your server

Step 1 - Install Golang

Gatus is built using the Go programming language, so we need to install Golang on our server.

First, update the package repositories and upgrade the system.
```
sudo apt update && sudo apt upgrade -y
```
Install Golang using the apt package manager.
```
sudo apt install golang-go -y
```

Step 2 - Clone the Gatus Repository

Now that we have installed Golang, we can clone the Gatus repository from Github.

Install git using the apt package manager.
```
sudo apt install git -y
```
Clone the Gatus repository using the git clone command.
```
git clone https://github.com/TwiN/gatus.git
```

Step 3 - Build the Gatus Binary

After we have cloned the Gatus repository, we can build the Gatus binary using the make command.

Change into the Gatus directory.
```
cd gatus
```
Run the make command to build the Gatus binary.
