This repository contains a set of GitOps infrastructure-as-code designs for Argo CD. Three designs that grow in complexity (as well as feature set) are in this repositories design directories.
design-01 Only uses Application resources. While simpler to understand and implement, this design requires PRs for each new app to be "watched" by Argo CD.
design-02 This design uses ApplicationSet to watch a group of apps via a single kubectl apply. This is a good enhancement over design-01 because it reduces the number of PRs needed to add a new app or environment. No real downsides once you understand both Application and ApplicationSet resources.
design-03 This design uses Argo CD Autopilot to manage Argo CD itself, as well as the namespaces and Application Sets. Everything but a single kubectl apply is automated by Argo CD. The repo and YAML relationships are more complex, and introduces AppProject and additional JSON files. This design is the most complex, but also the most powerful.
