The DevOps Journey

🛠 Prerequisites Windows 7+ / Windows Server 2012+ PowerShell (run as Administrator ) Internet connection 🔹 Step 1: Open PowerShell as Administrator Press Start → Search "PowerShell" Right-click → Run as administrator 🔹 Step 2: Run the Chocolatey Installation Script Copy and paste the following command into PowerShell: Set-ExecutionPolicy Bypass -Scope Process -Force; ` [System.Net.ServicePointManager]::SecurityProtocol = ` [System.Net.ServicePointManager]::SecurityProtocol -bor 3072; ` iex ((New-Object System.Net.WebClient).DownloadString('https://community.chocolatey.org/install.ps1')) ⚠️ Make sure PowerShell is running as administrator — otherwise it will fail. 🔹 Step 3: Verify Chocolatey Installation After installation, close and reopen PowerShell or Command Prompt. Then check: choco --version ✅ You should see something like 1.4.0 or the latest version. 🎯 Done!

The choice between "Quick configuration (with EKS Auto Mode)" and "Custom configuration" (whether Auto Mode is enabled or disabled) depends on your specific needs, expertise, and level of control required. 🔹 1. Quick Configuration (with EKS Auto Mode) What it is: A simplified, wizard-driven option in the AWS Console designed to get an EKS cluster running in Auto Mode with minimal setup. It uses AWS-recommended defaults for IAM roles, VPC, subnets, and add-ons. When it's recommended: Getting Started / Proof of Concept: Ideal for beginners wanting to quickly try EKS. Developers Focused on Apps: Great for teams that don’t want to manage infrastructure. Simple Workloads: Suitable for apps without complex infrastructure needs. Reduced Operational Overhead: Combines automation of node management, scaling, patching, and add-ons with simple UI-driven setup. ✅ Pros: Fastest way to spin up a cluster. Minimal configuration effort. E...

When running an Amazon EKS (Elastic Kubernetes Service) cluster, worker nodes are the compute resources that run your application Pods. AWS provides several powerful options to support a variety of operational, cost, and control needs. In this post, we’ll break down the four primary worker node options in EKS , along with their pros, trade-offs, and best practices. Whether you're a beginner or a seasoned DevOps engineer, this guide will help you choose the right approach for your workloads. ✅ 1. EKS Auto Mode (Recommended for Most New Deployments) 🔍 What It Is: EKS Auto Mode is the latest and most automated way to run worker nodes. AWS provisions and manages EC2 instances behind the scenes using a Karpenter-powered model. It also handles scaling, patching, and core Kubernetes add-ons. ⚙️ Management Level: Very High – AWS manages everything: nodes, add-ons, and scaling logic. 🔒 Control: Limited control over EC2 instances, but flexible via NodeClasses for spe...

Published on: June 16, 2025 Author: Shubham Agrawal 🔍 Introduction In the world of DevOps, “you can’t improve what you can’t measure.” Monitoring is no longer a post-deployment afterthought — it’s a core pillar of modern DevOps practices . A robust monitoring strategy helps teams detect issues early, maintain uptime, improve performance , and deliver a better customer experience. In this post, we’ll explore what monitoring means in DevOps, key tools, best practices, and how it fits into the overall DevOps lifecycle. 📌 What is DevOps Monitoring? DevOps Monitoring is the continuous process of collecting, analyzing, and visualizing system data to understand application behavior and infrastructure performance. It covers: Application Monitoring Infrastructure & Server Monitoring Log Monitoring Network Monitoring Security Monitoring User Experience Monitoring The goal is simple: get real-time visibility across the entire stack — from code to produc...

Learn how to configure the AWS CLI, build a Docker image, and push it to Amazon Elastic Container Registry (ECR) in a few simple steps. 🔧 Prerequisites ✅ Docker installed and running ✅ AWS CLI installed ( aws --version ) ✅ IAM user with programmatic access and ECR permissions ✅ Access Key and Secret Key for the IAM user ✅ An Amazon ECR repository already created (e.g.  731733338449.dkr.ecr.ap-south-1.amazonaws.com/myrepo ) ✅ Step 1: Configure AWS CLI Run the command: aws configure Provide: AWS Access Key ID :  Your IAM access key AWS Secret Access Key :  Your IAM secret key Default region name :  ap-south-1 Default output format :  json This saves config in  ~/.aws/credentials  and  ~/.aws/config ✅ Step 2: Authenticate Docker with Amazon ECR aws ecr get-login-password --region ap-south-1 \ | docker login --username AWS --password-stdin 731733338449.dkr.ecr.ap-south-1.amazonaws.com On success: Login Succeeded ✅ Step 3: Create a Dockerfile (Optio...
