SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

An ArgoCD app reports OutOfSync but argocd app diff shows no output. The drift is caused by a CRD managed by an operator that applies default field values after install, values that ArgoCD never renders in its diff.

Core Features & Use Cases

  • Detect OutOfSync with an effectively empty diff caused by operator-defaults on CRDs.
  • Compare desired Helm-rendered specs with live cluster, identify differences that ignoreDifferences misses.
  • Update ArgoCD Application ignoreDifferences to account for operator-defaulted fields and verify sync.

Quick Start

Run the guided steps to compare Helm-rendered and live CRD specs and update ArgoCD ignoreDifferences accordingly.

FAQPage Schema
Why does my ArgoCD app show OutOfSync when argocd app diff shows no output?▼

An ArgoCD app shows OutOfSync with an empty diff when an operator applies default field values to a CRD after install, causing cluster drift that ArgoCD detects but does not render.

How do I fix ArgoCD OutOfSync status on operator-managed CRDs?▼

Fix ArgoCD OutOfSync on operator-managed CRDs by comparing the Helm-rendered desired state with the live cluster, identifying the operator-defaulted fields, and adding them to the Application ignoreDifferences list.

What is the best way to find CRD drift that ArgoCD ignoreDifferences misses?▼

To find CRD drift that ignoreDifferences misses, compare the Helm-rendered desired spec against the live cluster resource to expose operator-defaulted fields causing the silent OutOfSync status.

Can I use ignoreDifferences to resolve ArgoCD OutOfSync caused by Kubernetes operator defaults?▼

Yes, you can resolve ArgoCD OutOfSync from operator defaults by identifying the exact default fields injected into the live CRD and updating the ignoreDifferences configuration to exclude those fields.

When should I update ArgoCD ignoreDifferences for an OutOfSync CRD?▼

Update ArgoCD ignoreDifferences for an OutOfSync CRD when an operator sets default values post-install, creating live cluster drift that prevents the application from reaching a Synced state.

Does this approach work for ArgoCD apps deployed with Helm and managed by a Kubernetes operator?▼

Yes, this approach works for ArgoCD apps deployed with Helm where a Kubernetes operator sets default CRD fields after installation, causing the live state to diverge from the rendered desired state.
