Flux Kustomize DependsOn Quick Fix - Kustomization Ordering

Flux Kustomization dependsOn ensures resources are applied in the correct order. Missing or circular dependencies cause reconciliation failures. This guide covers the fix.

Quick Fix

Wrong

apiVersion: kustomize.toolkit.fluxcd.io/v1beta2
kind: Kustomization
metadata:
  name: apps
spec:
  dependsOn:
  - name: infrastructure
  path: ./apps

The issue: dependsOn references infrastructure but does not specify namespace. If infrastructure is in a different namespace, the dependency never resolves.

Right

apiVersion: kustomize.toolkit.fluxcd.io/v1beta2
kind: Kustomization
metadata:
  name: apps
  namespace: teams
spec:
  dependsOn:
  - name: infrastructure
    namespace: infra
  - name: security
    namespace: infra
  path: ./apps
  prune: true

# Expected output after applying the fix
# Kustomization apps depends on infrastructure and security
# Dependencies reconciled first (infra namespace)
# apps reconciled after dependencies are ready
# Status: True (Ready)

Prevention

• Always specify both name and namespace in dependsOn
• Define explicit dependency chains for resource ordering
• Avoid circular dependencies between Kustomizations
• Verify dependency resolution with flux get kustomizations
• Use dependency chains for infrastructure before application resources
