Git Installation and Configuration – Version Control Foundation

Git is the cornerstone of every DevOps workflow, enabling collaboration, version history, and CI/CD integration. For Bangalore beginners, installing Git on Ubuntu is straightforward, but configuring it with SSH keys and local mirrors speeds up operations in shared networks. Start by updating your package list with sudo apt update, then sudo apt install git. Verify with git --version, which should show 2.34+ for modern features. On Windows, use Git Bash from the official installer, ensuring PATH is set for command line access. Configure your global settings with git config --global user.name "Your Name" and git config --global user.email "[email protected]". For SSH, generate keys with ssh-keygen -t ed25519 and add the public key to GitHub. Bangalore learners often face slow GitHub pushes due to ISP throttling; use git config --global http.postBuffer 524288000 to increase buffer size. DevOps Training Institute emphasizes early Git mastery, as 80% of interview questions involve branching strategies and merge conflicts. Practice with a sample repo: clone, branch, commit, and push your first change to build confidence.

Jenkins Setup – Your First CI/CD Pipeline Server

Jenkins, the de facto CI/CD tool, transforms code commits into deployable artifacts. In Bangalore's startup ecosystem, Jenkins runs 65% of pipelines, so setting it up correctly is crucial. On Ubuntu, add the repository with wget -q -O - https://pkg.jenkins.io/redhat-stable/jenkins.repo | sudo tee /etc/yum.repos.d/jenkins.repo, then sudo yum install jenkins. Start the service with sudo systemctl start jenkins and access via http://localhost:8080. Initial setup requires generating an admin password from sudo cat /var/lib/jenkins/secrets/initialAdminPassword. Install plugins like Pipeline, Docker Pipeline, and AWS Steps for comprehensive workflows. For Windows, download the .msi installer and run as a service. Configure security with role-based access and webhook integration from GitHub. Common Bangalore issue: port 8080 blocked by corporate firewalls; use sudo ufw allow 8080 or configure reverse proxy with Nginx. DevOps Training Institute starts every batch with building a simple "Hello World" pipeline, teaching you to troubleshoot agent disconnections and plugin conflicts early. This setup forms the backbone for deploying Docker images and Kubernetes manifests in later modules.

Docker Installation and Container Fundamentals

Docker revolutionizes application packaging, enabling consistent environments from dev to prod. In Bangalore's microservices-heavy landscape, 85% of DevOps roles require Docker proficiency. Install on Ubuntu with sudo apt update && sudo apt install docker.io, then add your user to the docker group: sudo usermod -aG docker $USER. Logout and login to apply. Verify with docker --version. For Windows, use Docker Desktop with WSL2 backend, ensuring Hyper-V is enabled. Pull your first image with docker pull nginx and run docker run -d -p 80:80 nginx. Explore volumes with docker run -v /host/path:/container/path nginx for data persistence. Bangalore learners face slow image pulls due to international bandwidth limits; configure domestic mirrors with daemon.json pointing to registry.aliyuncs.com. DevOps Training Institute dedicates Week 3 to Docker, where students build multi-stage images for Node.js apps, reducing size from 900MB to 120MB. This hands-on approach ensures you understand layering, caching, and security scanning with Trivy before moving to Kubernetes.

Kubernetes Installation – Local to Cloud Cluster Setup

Kubernetes, the container orchestrator, powers 59% of Bangalore's production workloads. Start locally with Minikube: curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64 && sudo install minikube-linux-amd64 /usr/local/bin/minikube. Launch with minikube start --driver=docker. For cloud, use AWS EKS: create cluster with eksctl create cluster --name my-cluster --region ap-south-1. Install kubectl with curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl". Verify connectivity with kubectl get nodes. Windows users use Chocolatey: choco install kubernetes-cli. Bangalore's variable internet makes local Minikube essential for offline practice; allocate 4GB RAM to avoid OOM kills. DevOps Training Institute teaches EKS setup in Week 5, where students deploy a 3-node cluster and scale it to handle 1,000 RPS. This project simulates Flipkart's Black Friday traffic, preparing you for high-load scenarios in interviews.

Terraform Setup – Infrastructure as Code Mastery

Terraform enables declarative infrastructure, reducing errors by 70%. Install with sudo apt-get install -y software-properties-common followed by wget -O- https://apt.releases.hashicorp.com/gpg | gpg --dearmor | sudo tee /usr/share/keyrings/hashicorp-archive-keyring.gpg and echo "deb [signed-by=/usr/share/keyrings/hashicorp-archive-keyring.gpg] https://apt.releases.hashicorp.com $(lsb_release -cs) main" | sudo tee /etc/apt/sources.list.d/hashicorp.list. Then sudo apt update && sudo apt install terraform. Verify with terraform version. For Windows, download the .exe from HashiCorp. Configure providers in terraform.tf with provider "aws" { region = "ap-south-1" }. Bangalore's multi-cloud trend requires AWS and Azure providers; set credentials via export AWS_ACCESS_KEY_ID=yourkey. DevOps Training Institute Week 6 focuses on Terraform, where students provision a VPC with EC2 instances and RDS, applying state locking with S3 backend.
