13GitOps Environment Layouts: Monorepo, Polyrepo, Overlays & Promotion PathsChoose a scalable repository layout for many services and environments, including ownership, review boundaries and promotion mechanics.Intermediate · 38 min readLockedLocked
14App of Apps Pattern: Bootstrapping Application Trees Without Losing OwnershipUse parent Applications to bootstrap groups of child Applications while understanding ordering, permission and blast-radius concerns.Advanced · 38 min readLockedLocked
15ApplicationSet Mental Model: Generate Applications Declaratively at ScaleUnderstand ApplicationSet as an Application generator for multi-cluster, multi-tenant and repository-driven fleet management.Intermediate · 40 min readLockedLocked
16ApplicationSet Generators: List, Git, Cluster, Matrix, Merge & Pull RequestSelect and combine ApplicationSet generators for cluster fleets, repository directories, environment matrices and preview workflows.Advanced · 48 min readLockedLocked
17Multi-Cluster GitOps: Cluster Registration, Credentials & Fleet BoundariesManage multiple Kubernetes clusters from Argo CD while controlling cluster credentials, destination permissions, failure domains and blast radius.Advanced · 44 min readLockedLocked
18AppProjects: Multi-Tenancy, Trusted Sources, Destinations & Resource KindsUse AppProjects as a guardrail around what applications may source, where they may deploy and which Kubernetes resource types they may manage.Advanced · 44 min readLockedLocked
19Argo CD RBAC, SSO & Least PrivilegeDesign Argo CD human and automation access using SSO groups, global RBAC, project roles and minimal default permissions.Advanced · 48 min readLockedLocked
20Repository Credentials, Private Git, Helm Repositories & Credential TemplatesConnect private Git and Helm sources securely, understand repository credential storage and avoid leaking tokens or SSH keys into manifests and logs.Intermediate · 40 min readLockedLocked
21Secrets in GitOps: External Secrets, Sealed Secrets, SOPS & Secret BoundariesKeep Git as the desired-state source without committing plaintext credentials, and understand common secret-reference/decryption patterns.Advanced · 46 min readLockedLocked
22Sync Hooks, Phases & Waves: Ordered Deployments Without Imperative PipelinesControl deployment ordering with PreSync, Sync and PostSync hooks plus sync waves, while avoiding fragile imperative orchestration.Advanced · 46 min readLockedLocked
23Resource Health, Custom Health Checks & Application ReadinessUnderstand built-in resource health, custom health behavior and why Kubernetes object existence is not the same as application readiness.Advanced · 40 min readLockedLocked
24Diffing & Ignore Differences: Drift Without False PositivesDebug persistent OutOfSync states caused by defaults, mutation and controller-owned fields, then use ignore rules narrowly and safely.Advanced · 46 min readLockedLocked
25Progressive Delivery with Argo Rollouts: Canary & Blue/Green IntegrationCombine GitOps reconciliation with Argo Rollouts for canary and blue/green strategies, traffic shifting and analysis-based promotion.Advanced · 48 min readLockedLocked
