    5. Hands-on: Lab: Install FluxCD and bootstrap a GitOps repo for a Kubernetes cluster
  • Module 4: GitOps Repository Design (Single Env and Multi-Env Delivery)
    1. Repo structure patterns (apps vs infra, mono-repo vs multi-repo)
    2. Single environment structure (simple production-ready layout)
    3. Multi-environment structure (dev/stage/prod) and promotion workflow
    4. Ownership boundaries and scalable structure for multiple teams
    5. Hands-on: Workshop: Design a multi-environment GitOps repo layout with promotion rules
  • Module 5: Deploying Apps with Raw YAML and Kustomize (Flux Kustomization)
    1. Deploying raw YAML using Flux Kustomization
    2. Kustomize fundamentals (bases, overlays, patches)
    3. Config patterns using ConfigMaps and Secrets (safe injection concepts)
    4. Validation and build failures (common Kustomize error patterns)
    5. Hands-on: Lab: Deploy an application using Kustomize overlays for dev and prod environments
  • Module 6: Helm GitOps with Flux (HelmReleases and Reconciliation)
    1. Helm in GitOps workflows (values as code)
    2. HelmRepository and HelmRelease objects
    3. Version pinning, upgrades, and rollback patterns
    4. Helm reconciliation troubleshooting (timeouts, chart errors, values issues)
    5. Hands-on: Lab: Deploy an application with HelmRelease and override values per environment
  • Module 7: Production-Ready Kubernetes Workloads for GitOps
    1. Probes (liveness/readiness) and safe rollout behavior
    2. Resource requests/limits and stability patterns (OOMKilled prevention)
    3. securityContext hardening (runAsNonRoot, drop capabilities concepts)
    4. Configuration best practices (ConfigMaps, Secrets, env patterns)
    5. Hands-on: Lab: Harden a workload with probes, resources, and securityContext and deploy via Flux
  • Module 8: GitOps Lifecycle (Promotion, Rollback, Drift Self-Heal)
    1. Promotion via pull requests (environment overlays and approvals)
    2. Rollback via Git revert and last-known-good commit pinning
    3. Drift detection and self-healing behavior in Flux
    4. Release safety practices (progressive changes and verification)
    5. Hands-on: Lab: Promote a version dev → prod, simulate drift, and rollback using Git revert
  • Module 9: Troubleshooting FluxCD and Kubernetes Failures
    1. Sync issues (auth problems, repo fetch failures, source not ready)
    2. Kustomize build failures (invalid patches, missing resources, wrong paths)
    3. Helm reconciliation problems (chart fetch failures, values mismatch, timeouts)
    4. Workload failures (CrashLoopBackOff, ImagePullBackOff, OOMKilled, Service/Ingress issues)
    5. Hands-on: Lab: Fix broken GitOps deployments by reading Flux status, events, and logs
