Deploying Prometheus and Grafana on Kubernetes

Introduction: This document explains how to deploy Prometheus and Grafana on a Kubernetes cluster manually, without using Helm or other automation tools. you will learn how to: Prerequisites: Create a section for what must be ready before starting: What is Prometheus? Kubernetes → Prometheus → Metrics + Alerts What is Grafana? Why Do We Need […]

Dynamic Storage in Kubernetes using OpenEBS with StatefulSets

Introduction: Persistent storage is a crucial requirement for stateful applications running on Kubernetes. OpenEBS provides a cloud-native solution for dynamic storage provisioning, enabling pods to retain data even when they are restarted or rescheduled. By leveraging OpenEBS, Kubernetes users can create custom StorageClasses and dynamically allocate Persistent Volumes (PVs) using Persistent Volume Claims (PVCs). This […]

Kubernetes Resource Management: Pods, Resource Requests, Limits, and ResourceQuota

Deploying a StatefulSet with Manual Persistent Volume (hostPath) in Kubernetes-(Tutorial-II)

Introduction In Kubernetes, StatefulSets are used to run stateful applications that require stable storage, ordered deployment, and persistent identities.In this guide, we manually create a PersistentVolume (PV) using hostPath, then deploy a StatefulSet that uses this PV for data persistence. In Kubernetes, some applications need to store data permanently and keep their names stable even […]

Kubernetes ServiceAccount and RBAC: Creating Pods with Controlled Permissions

Introduction In Kubernetes, a ServiceAccount is a special type of account used by pods to authenticate and interact with the kubernetes API. Every pod runs as a user, and the ServiceAccount determines what resources the pod can access. Role-Based Access Control (RBAC) is a security mechanism in Kubernetes that allows administrators to control who can […]

Introduction to Amazon Elastic Container Service (ECS)

Introduction Amazon ECS is a fully managed container orchestration service that helps you run, manage, and scale Docker containers on AWS. It removes the need to set up your own container management system by providing built-in scheduling, networking, and scaling features, so you can easily deploy containerized applications with high reliability and performance. Lab Steps […]

Create an AWS EC2 Instance and run some AWS CLI Commands.

Introduction. Creating an AWS EC2 Instance and running AWS CLI commands means launching a virtual server in AWS and then using the AWS Command Line Interface to perform basic operations such as checking resources, managing services, or testing AWS access directly from that server’s terminal. Lab Steps Step 1: Sign to the AWS Management Console 1. […]

Step-by-Step: Mount EFS on EC2.

Introduction. Amazon Elastic File System (EFS) is a scalable and fully managed network file system that allows multiple EC2 instances to access shared storage simultaneously. It is designed to provide elastic capacity, meaning it can automatically grow and shrink as you add or remove files, eliminating the need to provision storage in advance. Mounting EFS […]

How to Use Git the Right Way in a Team Environment.

Introduction. Using Git effectively in a team environment is more than just knowing commands. It is about collaboration, organization, and maintaining a clean history. Teams working on software projects face constant challenges. Code conflicts, inconsistent workflows, and lost changes are common pitfalls. Git provides a solution to these challenges by tracking changes. It allows multiple […]
