Argo CD ApplicationSet lets you standardize deployments across clusters, store manifests in Git, and enforce trust boundaries while providing automated sync and health checks.
Use Argo CD ApplicationSet with the cluster generator to create one Application per registered cluster automatically, plus verification and RBAC limits.
Learn how a single ApplicationSet definition can create dozens of Argo CD Applications from a matrix of clusters and environments, reducing boilerplate while keeping sync policies and Helm value overrides under control.
When Argo CD’s ApplicationSet controller can’t clone a Git repo, logs show a "failed to clone" or "authentication failed" error. This guide walks through common credential issues, a diagnostic table, step‑by‑step checks, fixes, and escalation steps to restore sync.
Stop duplicating Argo CD manifests. Use ApplicationSets to automate the creation of multiple Applications across dev, staging, and prod using a single template.
Stop duplicating Argo CD Application manifests. Learn how to use ApplicationSets and generators to automate multi-cluster deployments from a single template.
Automatically create an Argo CD Application for each subdirectory under values/ in a Git repository, so that every environment (e.g., dev, staging, prod) gets its own Helm release using the same chart but its own values file.
Decide whether Argo CD ApplicationSet fits your multi-app rollout, compare generators, and validate generated Applications with kubectl and argocd CLI.
Stop copy-pasting Application manifests. Use Argo CD ApplicationSet generators to create Applications dynamically, with a practical example and operational caveats.
