What is ArgocdImageUpdater?

A guide for ArgoCD Image Updater, a tool that updates container images managed by ArgoCD, a Kubernetes delivery system. It covers configuration, update rules, and fixing differences between the intended and running setup.

Use it to configure Image Updater, manage its custom resources, resolve drift, and diagnose related ArgoCD problems.

It helps troubleshoot image-update drift and keep image updates scoped to the right environments and clusters.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00059	$0.00472
Opus 5	$0.00030	$0.00236
Sonnet 5	$0.00012	$0.00094
Haiku 4.5	$0.00006	$0.00047

Security

Grade A, and why

ArgocdImageUpdater scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

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

Full documentation: See context files in this skill directory.

Files

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
