What is the roadmap should i follow to learn DevOps?

Phase 1: Foundation — Understand What DevOps Really Is

Goal: Know what DevOps means and why it exists.

Learn:

• What is DevOps? (Culture + Practices + Tools)

• DevOps lifecycle: Plan → Code → Build → Test → Release → Deploy → Monitor → Feedback

• The difference between Agile, CI/CD, and DevOps

• Core DevOps principles: Collaboration, Automation, Continuous Delivery

Resources:

• “The Phoenix Project” (Book)

• YouTube: “What is DevOps in 10 minutes”

Phase 2: Learn Linux Fundamentals

Goal: Be comfortable working in Linux environments — most DevOps tools run on Linux.

Learn:

• Basic commands (ls, cat, grep, awk, sed, etc.)

• File system structure

• Users, groups, permissions

• Package management (apt, yum)

• Shell scripting (bash/zsh)

• System monitoring (top, htop, df, ps, netstat)

Project Idea:
Write a Bash script that backs up log files and compresses them daily using cron.

Phase 3: Master Git & GitHub (Version Control)

Goal: Learn how teams collaborate and manage code versions.

Learn:

• Git basics: init, clone, commit, push, pull, merge

• Branching strategies (feature branches, GitFlow)

• Resolving conflicts

• Working with pull requests

• GitHub Actions (basic CI/CD pipelines)

Project Idea:
Create a GitHub repo, push code, and set up a CI workflow that runs tests on every commit.

Phase 4: Build Automation & Package Management

Goal: Automate builds and dependency management.

Learn:

• Build tools: Maven, Gradle, or npm/yarn (based on tech stack)

• Package managers (NuGet, pip, npm)

• Continuous Integration basics

Project Idea:
Set up a Node.js or .NET project and use GitHub Actions or Jenkins to build it automatically on every push.

Phase 5: Learn CI/CD (Continuous Integration & Deployment)

Goal: Automate the build → test → deploy pipeline.

Tools to Learn:

• Jenkins (Most popular)

• GitHub Actions

• GitLab CI/CD

• Azure DevOps Pipelines

Learn:

• CI/CD pipeline stages

• Build triggers

• Environment variables and secrets

• Artifact management

• Rollback and versioning

Project Idea:
Create a Jenkins pipeline that builds and deploys a simple web app to a staging server automatically.

Phase 6: Learn Docker (Containerization)

Goal: Package applications into portable containers.

Learn:

• Docker architecture (client, daemon, images, containers)

• Dockerfile (writing and building images)

• Docker Compose

• Volume, Networks, Ports

• Multi-stage builds

Project Idea:
Containerize a simple React + .NET API app and run both with docker-compose.

Phase 7: Learn Kubernetes (Orchestration)

Goal: Deploy, scale, and manage containers in clusters.

Learn:

• Kubernetes architecture (Pod, Node, Cluster, Deployment, Service)

• kubectl commands

• YAML manifests (deployment, service, ingress)

• ConfigMaps, Secrets

• Helm (package manager for K8s)

• Scaling and self-healing

Project Idea:
Deploy your Dockerized app on a local Kubernetes cluster (Minikube or Kind) and expose it using a LoadBalancer.

Phase 8: Learn Cloud Platforms

Goal: Learn how to deploy infrastructure and apps on the cloud.

Start with One Cloud:

• Azure (recommended for .NET developers)

• AWS

• GCP

Learn:

• Compute (VMs, App Services, Lambda)

• Storage (S3, Blob)

• Networking (VNet, Load Balancer)

• Identity (IAM, Managed Identity)

• Monitoring (CloudWatch, Azure Monitor)

Project Idea:
Deploy your containerized app on Azure Kubernetes Service (AKS) or AWS EKS.

Phase 9: Infrastructure as Code (IaC)

Goal: Automate infrastructure setup using code.

Tools:

• Terraform (most widely used)

• Ansible or Chef (for configuration management)

• Pulumi (modern alternative)

Learn:

• Terraform basics (provider, resource, variable, module)

• Ansible playbooks & roles

• Deploy full infrastructure on AWS/Azure using Terraform

Project Idea:
Use Terraform to create a Kubernetes cluster and deploy your app automatically.

Phase 10: Monitoring, Logging & Security

Goal: Ensure system reliability and observability.

Tools:

• Prometheus + Grafana (monitoring)

• ELK Stack (Elasticsearch, Logstash, Kibana) (logging)

• Datadog, New Relic, or Azure Monitor

• SonarQube, Snyk, or Trivy (security & vulnerability scanning)

Project Idea:
Set up a Grafana dashboard to monitor CPU, memory, and network usage of your Kubernetes pods.

Phase 11: Advanced Topics

Learn:

• Service Mesh (Istio, Linkerd)

• GitOps (ArgoCD, FluxCD)

• Secrets Management (Vault, AWS Secrets Manager)

• Blue-Green / Canary Deployments

• DevSecOps – integrating security into DevOps pipelines

• FinOps – cost optimization in the cloud

Phase 12: Build Real-World Projects

1. CI/CD for a Full-Stack App

   • React frontend + .NET API + SQL Server

   • Jenkins pipeline → Docker → AKS

2. Terraform + Ansible Automation

   • Automate VM provisioning and configuration

3. Monitoring Stack Setup

   • Prometheus + Grafana dashboard on Kubernetes
