🔹 Introduction
In the previous blog, we explored what DevOps is, why it’s important, and how top companies use it to release software faster and more reliably.
Now, let’s take it a step further— How do you actually start learning DevOps? 🤔
With so many tools, technologies, and practices involved, getting started can feel overwhelming. But don’t worry! By following a structured approach, learning DevOps becomes clear and achievable.
👉 By the end of this blog, you’ll have a solid roadmap to navigate your DevOps journey effectively.
🛠 Step 1: Master the Fundamentals
🔹 1. Learn Linux & Command Line
Most DevOps environments run on Linux, so understanding its fundamentals is essential.
📌 Key Topics to Focus On:
✅ Basic Linux commands (ls, cd, mkdir, grep, find, chmod, chown)
✅ File system & permissions
✅ Process management (top, ps, kill)
✅ Networking basics (ping, curl, wget, netstat)
🛠 Hands-on Practice:
Use Ubuntu on WSL to practice commands.
Set up a simple web server using nginx or Apache.
🔹 2. Learn Git & Version Control
Version control is essential for tracking changes, collaborating, and automating workflows.
📌 Key Topics to Focus On:
✅ Git basics (clone, commit, push, pull, merge, rebase)
✅ Branching strategies (GitFlow, trunk-based development)
✅ Working with GitHub/GitLab
✅ Pull requests & code reviews
🛠 Hands-on Practice:
Create a GitHub repository and track code changes using Git.
Collaborate on open-source projects.
🔹 3. Understand Networking Concepts
A strong grasp of networking helps in troubleshooting, security, and optimizing cloud deployments.
📌 Key Topics to Focus On:
✅ OSI & TCP/IP models
✅ DNS, HTTP, HTTPS, SSL/TLS
✅ Load balancers & reverse proxies
✅ Firewall basics
🛠 Hands-on Practice:
Use cURL & Postman to test APIs.
Set up an NGINX reverse proxy on a local machine.
🚀 Step 2: Learn DevOps Core Practices
🔹 4. Understand CI/CD Pipelines
CI/CD (Continuous Integration & Continuous Deployment) enables fast and automated software releases.
📌 Key Topics to Focus On:
✅ What is CI/CD?
✅ Writing CI/CD pipelines (YAML syntax)
✅ Automating builds, tests, and deployments
✅ Popular CI/CD tools (Jenkins, GitHub Actions, GitLab CI/CD)
🛠 Hands-on Practice:
Build a simple CI/CD pipeline using GitHub Actions.
Set up Jenkins on Docker and create an automated job.
🔹 5. Learn Containers & Docker
Containers provide portability and scalability for applications.
📌 Key Topics to Focus On:
✅ Docker architecture & CLI commands
✅ Writing Dockerfiles & Docker Compose
✅ Container networking & volumes
🛠 Hands-on Practice:
Create a Dockerized Python/Node.js app.
Deploy it using Docker Compose.
🔹 6. Learn Kubernetes
Kubernetes is the leading container orchestration tool for managing microservices.
📌 Key Topics to Focus On:
✅ Kubernetes architecture (Pods, Nodes, Deployments, Services)
✅ YAML configuration for Kubernetes objects
✅ Helm Charts for package management
🛠 Hands-on Practice:
Deploy an app on Minikube.
Explore kubectl commands.
🏗 Step 3: Infrastructure as Code & Automation
🔹 7. Learn Infrastructure as Code (Terraform & Ansible)
Infrastructure as Code (IaC) allows for consistent and automated provisioning of infrastructure.
📌 Key Topics to Focus On:
✅ Terraform: Writing .tf files, deploying AWS/Azure resources
✅ Ansible: Writing playbooks for automation
🛠 Hands-on Practice:
Write a Terraform script to provision an EC2 instance.
Use Ansible to automate package installations.
📊 Step 4: Monitoring, Logging & Security
🔹 8. Learn Monitoring & Logging
Observability is critical for maintaining system performance and troubleshooting issues.
📌 Key Topics to Focus On:
✅ Prometheus (metrics collection)
✅ Grafana (data visualization)
✅ ELK Stack (log management)
🛠 Hands-on Practice:
Set up Prometheus & Grafana to monitor a Dockerized app.
Deploy ELK Stack for log management.
🔹 9. Security in DevOps (DevSecOps)
Security should be integrated at every stage of DevOps (Shift Left Approach).
📌 Key Topics to Focus On:
✅ Security best practices in CI/CD
✅ Popular security tools: SonarQube, Trivy, Aqua Security
🛠 Hands-on Practice:
Scan Docker images for vulnerabilities using Trivy.
Implement SonarQube to analyze code security.
☁️ Step 5: Cloud & Reliability Engineering
🔹 10. Learn Cloud Computing (AWS, Azure, GCP)
Cloud platforms provide scalability, reliability, and cost optimization for DevOps workflows.
📌 Key Topics to Focus On:
✅ AWS (EC2, S3, Lambda, IAM, CloudWatch)
✅ Azure (VMs, AKS, DevOps Services)
✅ GCP (Compute Engine, GKE, Cloud Run)
🛠 Hands-on Practice:
Deploy a static website on AWS S3.
Launch a Kubernetes cluster on Azure AKS.
