This README is a simple roadmap to learn Kubernetes and related topics: CI/CD, GitOps, DevSecOps, and Kubeflow Pipelines. Each section explains:

• What it is (in plain words)
• Why it’s useful
• What you’ll learn
• The best videos and GitHub repos
• A tiny action to try

• Start with the section that feels right for you (beginner → advanced).
• Watch the YouTube video(s) and skim the GitHub repo(s).
• Do the small action at the end to practice.
• Take notes in a notes/ folder so you remember what worked.
• If this guide helps you, please ⭐ star the repo — it encourages more updates.

Why: Deploying a 3-tier app (frontend, backend, database) teaches you Deployments, Services, Ingress, and health checks.

You’ll learn:

• Service discovery via ClusterIP Services
• Liveness/readiness probes in Deployments
• Ingress routing for external traffic

Resources:

• YouTube:
  • Jenkins to Kubernetes pipeline overview: https://www.youtube.com/watch?v=RRCrY12VY_s
• GitHub:
  • Sample 3-tier app on AWS/K8s: https://github.com/iam-veeramalla/aws-devops-zero-to-hero/blob/main/day-22/sample-app.md

Action:

• Draft manifests for a simple frontend, backend, and Postgres.
• Add probes and expose via Ingress. Test rollouts and failures.

Why: Automate build, test, image packaging, and deployment using GitOps instead of manual kubectl.

You’ll learn:

• Jenkins pipelines and stages (build/test/package)
• Pushing images to a container registry
• GitOps with a manifests repo and Argo CD sync
• Quality gates with SonarQube

Resources:

• YouTube:
  • GitOps with Argo CD: https://www.youtube.com/watch?v=jNPGo6A4VHc
• GitHub:
  • Jenkins + Sonar + Argo CD + Helm K8s: https://github.com/iam-veeramalla/Jenkins-Zero-To-Hero/tree/main/java-maven-sonar-argocd-helm-k8s

Action:

• Write a Jenkinsfile that builds, tests, docker-builds, and pushes.
• Create a GitOps repo (Helm/Kustomize) and configure Argo CD to sync it.

Why: ML workflows are orchestrated as containerized steps; Kubeflow Pipelines lets you build and run DAGs on Kubernetes.

You’ll learn:

• Components and pipelines (DAGs)
• Uploading and running pipelines via KFP UI
• Monitoring runs and viewing artifacts

Resources:

• YouTube:
  • Ingress basics and routing (context on cluster exposure): https://www.youtube.com/watch?v=6wWdNg0GMV4
• GitHub:
  • Digits recognizer (Kubeflow example): https://github.com/flopach/digits-recognizer-kubeflow

Action:

• Implement a simple pipeline with two components (prep + train or echo).
• Upload it to KFP and inspect logs/results.

Why: Security isn’t a checkbox—integrate it across CI/CD and runtime for real resilience.

You’ll learn:

• GitHub Actions for CI
• Docker containerization
• Trivy for vulnerability scanning
• Argo CD for GitOps deployment
• Logging/monitoring strategies

Resources:

• YouTube:
  • DevSecOps-focused walkthrough: https://www.youtube.com/watch?v=Ke_Wr5zPE0A
• GitHub:
  • DevSecOps demo: https://github.com/iam-veeramalla/devsecops-demo

Action:

• Build a GitHub Actions workflow: build/test → docker build → Trivy scan → push image.
• Deploy to Kubernetes with Argo CD and add basic logs/metrics.

• Week 1: K8s fundamentals + Multi-tier app
• Week 2: CI pipeline + Docker registry
• Week 3: GitOps + SonarQube quality gates
• Week 4: DevSecOps + a simple Kubeflow pipeline

• Keep a notes/ folder with diagrams, learnings, and commands you used.
• Record short clips showing deployments and pipeline runs.
• Write a small blog post summarizing each section.
