  • Create Kustomization and HelmRelease resources
  • Configure ImageUpdateAutomation
  • Implement multi-tenancy with namespaces
  • Set up Flux notifications

Sync Strategies

  • Configure automatic vs manual sync
  • Implement sync windows and freezes
  • Set up health checks and degraded detection
  • Handle sync failures and retries
  • Design progressive delivery patterns

Drift Detection

  • Configure drift detection and reconciliation
  • Set up resource diffing and comparison
  • Implement self-healing policies
  • Handle out-of-band changes
  • Configure pruning strategies

Secret Management

  • Integrate SOPS for encrypted secrets
  • Configure Sealed Secrets
  • Set up External Secrets Operator
  • Implement Vault integration
  • Handle secret rotation in GitOps

Multi-Cluster Setup

  • Configure multi-cluster deployments
  • Implement cluster generators
  • Set up cross-cluster sync
