Argo CD Tutorial: App of Apps in 8 Minutes

hello and welcome to this video on the app of apps pattern for Argo CD I'm Nicholas Mori a developer Advocate at Acuity the Enterprise Argo company created by the founders of the Argo project so you're just starting off with Argo CD you're probably already a kubernetes user you're trying to implement get Ops principles for

managing the deployment of manifest to your kubernetes cluster now you've probably already learned that the application resource is at the core of Argo CD it's a declarative representation of how argocd will deploy a set of manifests to a kubernetes cluster it includes where to Source the Manifest from which cluster to create them in and

how to manage the deployment in the cluster and you know that an application can be created through the Argo CD dashboard using the Argo cdcli or by creating an application custom resource in kubernetes but you may have noticed that none of these methods are following git Ops principles they're all imperative even the one where you're creating a resource

in kubernetes you're still doing it manually so the question that you might ask yourself and that I asked myself when I was starting out with Argo CD is how can you manage applications declaratively well this is where the app of apps pattern comes in an application is simply another kubernetes resource along with the rest of the configuration for

Argo CD they're all represented as resources in kubernetes so you can use an application to deploy another application this is known as the app of apps pattern the app of apps pattern is most commonly used in the cluster bootstrapping scenario where you have Argo CD running you have a bear cluster ready for you to
