ArgoCD Image Updater

Operational skill for configuring and troubleshooting ArgoCD Image Updater in multi-cluster GitOps environments. Covers Helm chart configuration, ImageUpdater CRD management, drift resolution, and environment-scoped update patterns.

Workflow Routing

Workflow Trigger File
ResolveDrift "fix drift", "resolve drift", "orphaned resources" Workflows/ResolveDrift.md
ConfigureImageUpdater "configure image updater", "setup image updates" Workflows/ConfigureImageUpdater.md
CreateImageUpdaterCrds "create ImageUpdater CRD", "scope image updates" Workflows/CreateImageUpdaterCrds.md

Quick Reference

  • Chart: argocd-image-updater v1.1.1 (app v1.1.0) from argo-helm
  • CRD API: argocd-image-updater.argoproj.io/v1alpha1 kind ImageUpdater
  • Custom resources via Helm: Use extraObjects values key
  • Config format: Flat dotted keys (e.g., config.log.level), NOT nested maps
  • Metrics: Use --metrics-secure=false + port 8080 for HTTP Prometheus scraping

Key Patterns

  • Environment scoping: Create per-environment ImageUpdater CRs with namePattern (e.g., dev-*, hlg-*, prd-*)
  • Drift resolution: Bring manually-applied resources under GitOps via extraObjects in Helm values
  • ServerSideApply: Enables ArgoCD to adopt existing resources without conflicts
  • Registry auth: pullsecret:namespace/secret-name format for ACR credentials
