Summary

  • Advanced ArgoCD operations beyond the core CLI/API — multi-cluster ApplicationSet generators, automated image updates, new-cluster bootstrapping, and workload onboarding via templated ApplicationSets.
  • USE WHEN working with ApplicationSet CRDs (list, cluster, git, matrix, merge, SCM, pull request, plugin generators), configuring ArgoCD Image Updater (semver/digest/newest-build update strategies + git write-back), bootstrapping a new Kubernetes cluster into a multi-repo GitOps setup, registering clusters with proper labels for ApplicationSet targeting, onboarding a new workload via the standard ApplicationSet template, or troubleshooting any of these.
  • For routine app sync/status/diff work use the core `argocd` skill instead.

ArgoCD Advanced

Routing entrypoint for advanced/automation-oriented ArgoCD operations. Each sub-area has its own deep reference, preserved verbatim from the pre-consolidation skills, under References/.

Scope routing

If you need to… Read
Implement multi-cluster app propagation with ApplicationSet generators (list / cluster / git / matrix / merge / SCM / pull-request / plugin) References/applicationset.md plus References/applicationset/ for deep-dive reference docs

Decision tree

Need new cluster registered with ArgoCD?           -> cluster-bootstrapping
Need new service deployed to existing clusters?    -> application-install
Need to fan one app definition across N clusters?  -> applicationset
Need images to roll forward automatically?         -> image-updater

Gotchas

  • ApplicationSet generators are ordered. With matrix/merge generators, the parent generator's result is the input to the child — get the order wrong and you get an empty parameter set with no error.
  • Image Updater + git write-back requires a write credential. A read-only repo cred will silently leave images stuck on the original version. Check Image Updater pod logs for permission denied on push.
  • Bootstrap cluster secrets must carry the labels your ApplicationSet generators select on. A cluster registered without the expected label key/value is invisible to existing ApplicationSets — and there is no error, just zero apps.
  • application-install ships a your organization/ExampleApp-specific template. The Workflows assume the multi-repo layout. If you're not in that environment, treat it as a reference pattern, not a runnable recipe.
  • CRD versions matter. ApplicationSet ships with ArgoCD 2.3+; certain generators (SCM, pull request) need 2.5+. Read References/applicationset.md Version Compatibility before adopting.
