Overview

This project involves deploying a web application with a Postgres database, a Django application, an NGINX reverse proxy, and monitoring tools (Prometheus and Grafana). The deployment uses Docker and Docker Compose.

Prerequisites

1. System Requirements:

   • Linux-based OS (Ubuntu/Debian recommended).

2. Installed Tools:

   • Docker (>= 20.x).
   • Docker Compose (>= 2.x).

3. Required Files:

   • docker-compose.yaml
   • deployment.yaml
   • start.yaml

Installing the Package

1. Clone the repository:

   #bash git clone https://github.com/Nobodyknwme/Testtask cd Testtask

2. Install the required packages: #bash sudo apt update && sudo apt install -y docker.io docker-compose

Deploying the System

A. Using script setup.sh (Recommended for Automation) #bash cd Testtask chmod +x setup.sh ./setup.sh

B. Manual Deployment

1. Build and Start the Containers:

   #bash sudo docker-compose -f deployment.yaml up --build

2. Verify Running Containers: Run the following command to ensure all services are running:

   #bash sudo docker ps

   Expected output:

   • Postgres database container (Testtask-db-1)
   • Django application container (Testtask-django-1)
   • NGINX proxy container (Testtask-nginx-1)
   • Prometheus monitoring container (prometheus)
   • Grafana visualization container (grafana)

3. Access the Services:

   • NGINX reverse proxy: http://<your_server_ip>
   • Prometheus: http://<your_server_ip>:9090
   • Grafana: http://<your_server_ip>:3000 (default username/password: admin/admin)

Validating the Solution

1. Application Availability

• Open the NGINX URL (http://<your_server_ip>).
• Verify the Django application is accessible and functioning as expected.

2. Grafana Dashboards

• Log in to Grafana and navigate to the "Dashboards" section.
• Verify the pre-provisioned dashboard is loading and displaying data collected by Prometheus.

Notes

• For advanced debugging, check container logs:

  #bash sudo docker logs <container_name>
