15-Step Roadmap to Mastering DevOps: A Beginner-Friendly Guide

1. Understand the Basics of DevOps

• What is DevOps?: A methodology that integrates software development (Dev) and IT operations (Ops).
• Key Goals: Continuous integration, faster deployment, automation, and collaboration between teams.
• Key Concepts: CI/CD (Continuous Integration/Continuous Deployment), automation, and collaboration.

2. Learn Version Control (Git)

• Get familiar with Git: Learn how to use Git to manage and track code changes.
• Practice using GitHub/GitLab/Bitbucket: Host repositories, collaborate with others.
• Key commands: git clone, git commit, git push, git pull, git branch.

3. Understand Linux Basics

• Why Linux?: Most DevOps tools run on Linux.
• Learn basic Linux commands: ls, cd, mkdir, rm, cp, chmod, systemctl.
• Practice SSH: Learn to securely connect to remote servers using SSH.

4. Learn Scripting (Bash/Python)

• Why scripting?: Automating repetitive tasks is key in DevOps.
• Start with Bash: Learn to write simple scripts for task automation.
• Move to Python: A more versatile language used for automation, data processing, etc.

5. Get Started with Continuous Integration (CI)

• What is CI?: Automating the testing of your code every time you push changes.
• Tools: Jenkins, Travis CI, CircleCI.
• Learn how to create a CI pipeline: Integrate your GitHub/GitLab repository to trigger tests.

6. Learn Containerization (Docker)

• Why Docker?: Containers make apps portable, ensuring consistency across environments.
• Basic Docker commands: docker run, docker build, docker pull, docker-compose.
• Understand Dockerfiles: Learn to create Docker images.
• Docker Compose: Learn to manage multi-container apps.

7. Learn Infrastructure as Code (IaC)

• Why IaC?: Automating infrastructure provisioning using code.
• Start with Terraform: Learn to define cloud infrastructure in code.
• Use cloud providers: (AWS, GCP, Azure) and deploy resources like servers and databases.

8. Understand Configuration Management

• Why configuration management?: Automates the process of managing and configuring servers.
• Tools: Ansible, Puppet, Chef.
• Learn Ansible basics: Write playbooks to configure servers automatically.

9. Learn Continuous Deployment (CD)

• What is CD?: Automating the release of code to production.
• Tools: Jenkins, GitLab CI/CD, AWS CodePipeline.
• Learn to set up CD pipelines: Deploy code automatically after passing tests.

10. Learn Monitoring and Logging

• Why monitoring?: To track the health of your infrastructure and apps.
• Tools: Prometheus, Grafana (for monitoring), ELK Stack, Splunk (for logging).
• Learn to set up basic monitoring: Track CPU, memory, and network usage of your servers.

11. Understand Cloud Computing (AWS, GCP, Azure)

• Why cloud?: Most DevOps jobs require familiarity with cloud platforms.
• Learn basic services: Compute (EC2), Storage (S3), and Networking (VPC).
• Get hands-on: Deploy simple applications on a cloud platform (AWS free tier, GCP, or Azure).

12. Learn about Kubernetes (K8s)

• Why Kubernetes?: For managing containers at scale (Container Orchestration).
• Learn key concepts: Pods, deployments, services, namespaces.
• Practice with Minikube: Set up a local Kubernetes cluster.
• Understand Helm: A tool for managing Kubernetes applications.

13. Practice Building a Full DevOps Pipeline

• Combine all skills: CI/CD, Docker, Terraform, Ansible, and Kubernetes.
• Example project: Set up a full pipeline for an app from source code to production.

14. Focus on Security (DevSecOps)

• Why security matters: Integrating security practices into the DevOps pipeline is essential.
• Learn basic security practices: Secure code, server hardening, vulnerability scanning (Aqua, Clair).
• Integrate security tools into CI/CD pipeline.

15. Stay Updated & Practice

• Follow DevOps blogs and communities: DevOps.com, StackOverflow, Reddit.
• Contribute to open-source projects: Practice your skills and collaborate.
• Build projects: Automate and deploy personal projects using DevOps tools.
