If you’re new to DevOps and don’t know where to begin — this blog is for you. Whether you’re a fresher, a student, or switching careers, this step-by-step DevOps roadmap will guide you from zero to job-ready in 2025.
Written in simple words, this blog gives you clarity on what to learn, how to practice, and where to build your portfolio.
Step 1: Understand What DevOps Is
DevOps = Development + Operations
It’s a way of working where developers and operations teams work together to:
• Build code
• Test and deploy quickly
• Automate infrastructure
• Monitor everything
DevOps focuses on automation, speed, reliability, and collaboration.
Step 2: Learn the Basics of Linux
You must learn how to use the command line.
Learn:
• Basic Linux commands
• File system navigation
• Permissions (chmod, chown)
• Bash scripting
Free Resource: LinuxCommand.org
Step 3: Learn Git and GitHub
Version control is key in DevOps.
Learn:
• git init, clone, add, commit, push
• git branch, merge, pull requests
• GitHub for hosting code
Free Resource: learngitbranching.js.org
Step 4: Learn Scripting (Shell or Python)
Scripts help automate repetitive tasks.
Start With:
• Bash scripting (for Linux tasks)
• Python (for advanced automation)
Project Idea: Write a script to backup files daily using cron
Step 5: Learn CI/CD Concepts
CI/CD = Continuous Integration and Continuous Deployment
Tools to Learn:
• GitHub Actions (easy)
• Jenkins (popular)
• GitLab CI (powerful)
Project Idea:
• Auto-deploy your website when you push code to GitHub
Step 6: Learn Containers (Docker)
Containers let you package your app with everything it needs.
Learn:
• What is Docker
• Dockerfile
• Docker CLI commands
Project Idea: Dockerize a simple web app
Step 7: Learn Container Orchestration (Kubernetes)
Kubernetes helps run many containers easily.
Learn:
• Pods, Deployments, Services
• YAML files
• Minikube for local testing
Step 8: Learn Infrastructure as Code (IaC)
You write code to create infrastructure.
Tool: Terraform
Learn:
• Create AWS EC2 using Terraform
• Provision S3 buckets
Step 9: Learn Monitoring and Logging
Tools: Prometheus, Grafana, ELK Stack
Learn:
• Set up dashboards
• Collect system metrics
• Create alerts
Step 10: Build and Showcase Projects
Your projects are your resume.
Project Ideas:
• CI/CD pipeline for a portfolio site
• Docker + Kubernetes app deployment
• Terraform AWS infra setup
• Monitoring setup with Grafana
Tip: Push everything to GitHub and add a README.
Bonus: Learn Cloud (AWS Free Tier)
Most companies use cloud. Learn:
• EC2 (servers)
• S3 (storage)
• IAM (permissions)
• VPC (networking basics)
Final Words
You don’t need a degree or years of experience. You need:
• A learning plan
• Consistency
• Real projects
Use this roadmap and start building. DevOps is one of the best-paying and high-demand skills in tech today.
Keep it simple. Keep it practical.
