Why Learn DevOps?
DevOps bridges the gap between development and operations, enabling organizations to deliver software faster and more reliably. With cloud-native technologies like Docker and Kubernetes, DevOps practices have become essential for modern software engineering. This roadmap covers everything from version control to production monitoring.
DevOps Roadmap
- Version Control & GitBranching strategies, pull requests, code review workflows, and Git hooks.
- Linux & ScriptingLinux command line, shell scripting, process management, and system administration.
- CI/CD PipelinesAutomated builds, testing, and deployment with GitHub Actions, Jenkins, or GitLab CI.
- Containerization with DockerDockerfiles, multi-stage builds, Docker Compose, container networking, and registries.
- Orchestration with KubernetesPods, deployments, services, ingress, ConfigMaps, secrets, and Helm charts.
- Infrastructure as CodeTerraform or Pulumi for provisioning cloud resources. Declarative infrastructure management.
- Monitoring & ObservabilityPrometheus, Grafana, Loki, ELK stack, and distributed tracing with OpenTelemetry.
- Cloud PlatformsAWS, GCP, or Azure fundamentals. Compute, storage, networking, and managed services.
Key DevOps Skills
- Docker — Container creation, orchestration, multi-stage builds
- Kubernetes — Cluster management, pod scheduling, service discovery
- CI/CD — Pipeline design, automated testing, deployment strategies
- Cloud — AWS/GCP/Azure, serverless, managed services
- Monitoring — Metrics, logs, traces, alerting, dashboard creation
Sample Dockerfile
FROM node:20-alpine AS builder
WORKDIR /app
COPY package*.json ./
RUN npm ci
COPY . .
RUN npm run build
FROM node:20-alpine
WORKDIR /app
COPY --from=builder /app/dist ./dist
COPY package*.json ./
RUN npm ci --production
EXPOSE 3000
CMD ["node", "dist/index.js"]
Recommended Projects
- Set up a complete CI/CD pipeline for a web application
- Deploy a microservices app on Kubernetes
- Build a monitoring stack with Prometheus and Grafana
