Meet my homeLab Part-1

MireCloud Series — Part 1 I Was kubectl apply -ing Everything. Here's How I Stopped. Building MireCloud — the right way, from the ground up. EC Emmanuel Catin Senior Platform Engineer · CKA Vault ESO cert-manager ArgoCD Cilium I have a confession. For months, my homelab was held together with notes, memory, and hope. Keycloak was running. Grafana was up. GitLab was accessible. But if you asked me why something worked, half the time the honest answer was: "because I ran some commands six weeks ago and I haven't touched it since." Passwords lived in a notes file. Certificates were generated once with OpenSSL and forgotten until they expired. Secrets were committed to Git — sometimes as plaintext, sometimes base64-encoded, which is the same thing with extra steps. Every rebuild started ...

Building a Static Website on AWS with Terraform

The Journey to a Fully Automated Website Deployment A few weeks ago, I found myself needing to deploy a simple static website . Manually setting up an S3 bucket, configuring permissions, and linking it to a CloudFront distribution seemed like a tedious process. As someone who loves automation, I decided to leverage Terraform to simplify the entire process. Why Terraform? Infrastructure as Code (IaC) is a game-changer. With Terraform, I could:  Avoid manual setup errors  Easily reproduce and  Automate security best practices Instead of clicking through AWS settings, I wrote a few Terraform scripts and deployed everything in minutes. Let me walk you through how I did it!  Architecture Overview The architecture consists of three main components: User:  The end user accesses the website via a CloudFront URL.  CloudFront Distribution:  Acts as a content delivery network (CDN) to distribute content efficiently, reduce latency, and enhance security. It ...

Deploying a Scalable Monitoring Stack Lab on AWS using Terraform and Ansible

Deploying a Scalable Monitoring Stack Lab on AWS using Terraform and Ansible Introduction Effective monitoring is a cornerstone of cloud infrastructure management, ensuring high availability and performance. This guide provides a professional walkthrough on deploying Prometheus , Grafana , and Node Exporter on AWS using Terraform for infrastructure provisioning and Ansible for configuration management. This lab will create a prometheus server and a grafana server, It will install node exporter on both server. You should be able to see the metrics in grafana, we already install a node exporter dashboard for the user. The diagram below will give you an idea of what the architecture will look like If you want to replicate this lab, you can find the complete code repository here: GitHub - MireCloud Terraform Infra .  Infrastructure Setup with Terraform 1. Creating a Dedicated VPC To ensure isolation, we define a VPC named Monitoring with a CIDR block of 10.0.0.0/16 . reso...

FastAPI Instrumentalisation with prometheus and grafana Part1 [Counter]

welcome to this hands-on lab on API instrumentation using Prometheus and FastAPI! In the world of modern software development, real-time API monitoring is essential for understanding usage patterns, debugging issues, and ensuring optimal performance. In this lab, we’ll demonstrate how to enhance a FastAPI-based application with Prometheus metrics to monitor its behavior effectively. We’ve already set up the lab environment for you, complete with Grafana, Prometheus, and a PostgreSQL database. While FastAPI’s integration with databases is outside the scope of this lab, our focus will be entirely on instrumentation and monitoring. For those interested in exploring the database integration or testing , you can review the code in our repository: FastAPI Monitoring Repository . What You’ll Learn In this lab, we’ll walk you through: Setting up Prometheus metrics in a FastAPI application. Instrumenting API endpoints to track: Number of requests HTTP methods Request paths Using Grafana to vi...
