Roadmap To Become DevOps Engineer

Month 1: Linux, Networking, and Git Fundamentals

Goal: Get comfortable with Linux, servers, and version control.

Topics to Cover:

• Linux Basics:

  • File system, users & permissions

  • Shell scripting, cron jobs

  • Common commands (grep, awk, sed, curl, chmod, etc.)

• Networking Basics:

  • IP, DNS, HTTP/HTTPS, SSH, ports

  • Load balancing and firewalls

• Version Control (Git/GitHub):

  • Branching, merging, pull requests

  • Git workflows (Git Flow, feature branching)

Mini Projects:

• Automate system updates using bash script

• Backup script using cron job

• Create and manage GitHub repositories

Tools:

• Ubuntu / CentOS

• Git & GitHub

• VS Code Terminal

Month 2: Scripting & CI/CD Fundamentals

Goal: Learn automation scripting and continuous integration.

Topics to Cover:

• Scripting Languages:

  • Bash scripting (loops, functions, conditionals)

  • Python basics for automation (os, subprocess, boto3 for AWS)

• CI/CD Concepts:

  • Continuous Integration vs Deployment

  • Build, test, deploy lifecycle

  • Pipeline stages: build → test → deploy → monitor

• Jenkins / GitHub Actions:

  • Install & configure Jenkins

  • Create pipelines using Jenkinsfile

  • GitHub Actions workflow setup

Mini Projects:

• Build Jenkins pipeline to deploy a sample Node.js/React app

• Automate test execution on code push

Tools:

• Jenkins / GitHub Actions

• Docker (intro)

• Python 3

Month 3: Containers & Orchestration (Docker + Kubernetes)

Goal: Containerize applications and orchestrate using Kubernetes.

Topics to Cover:

• Docker:

  • Images, containers, volumes, networks

  • Dockerfile & Docker Compose

  • Multi-container apps (Frontend + Backend + DB)

• Kubernetes (K8s):

  • Pods, Deployments, Services, ReplicaSets

  • ConfigMaps & Secrets

  • Ingress, Scaling, Rolling updates

  • kubectl commands

• Container Registries: DockerHub, ECR, GCR

Mini Projects:

• Containerize a MERN app using Docker Compose

• Deploy a Dockerized app on Minikube / GKE

• Create a multi-pod deployment on Kubernetes

Tools:

• Docker

• Minikube / Kind / GKE

• kubectl

Month 4: Cloud, Infrastructure as Code (IaC), and Monitoring

Goal: Automate infrastructure provisioning and learn cloud operations.

Topics to Cover:

• Cloud Platforms (Pick One):

  • AWS (EC2, S3, IAM, CloudWatch, EKS, Lambda)

  • GCP (Compute Engine, GKE, Cloud Storage)

• Infrastructure as Code (IaC):

  • Terraform:

    • Providers, resources, variables, state

    • Terraform Cloud / Remote state

    • Automate EC2 + S3 setup

• Monitoring & Logging:

  • Prometheus + Grafana

  • CloudWatch / ELK Stack (ElasticSearch, Logstash, Kibana)

Mini Projects:

• Use Terraform to provision EC2 instance

• Deploy Dockerized app to AWS EC2 or GKE

• Setup monitoring dashboards for app metrics

Tools:

• Terraform

• AWS / GCP

• Prometheus + Grafana

Month 5: CI/CD + DevOps Projects + Resume Building

Goal: Build end-to-end CI/CD pipelines and prepare for DevOps interviews.

Topics to Cover:

• End-to-End DevOps Pipeline:

  • Code → Build → Test → Deploy → Monitor

  • Integration of Git + Jenkins + Docker + K8s + Cloud

• Security & Best Practices:

  • Secrets management (Vault / AWS Secrets Manager)

  • Role-based access control (RBAC)

• Advanced Tools (optional but valuable):

  • Ansible (Configuration Management)

  • Helm (K8s package manager)

  • ArgoCD (GitOps)

Projects (Choose 1–2):

1. CI/CD for MERN App:
   GitHub → Jenkins → Docker → K8s → AWS

2. Terraform + Jenkins Automation:
   Provision infrastructure + auto-deploy app

3. Monitoring Pipeline:
   Prometheus + Grafana + AlertManager

Resume Portfolio:

• Host your projects on GitHub

• Create DevOps Resume + LinkedIn portfolio

• Include architecture diagrams for each project
