Kubernetes Operator Summary 18 Chapter 3–Templating Everything in Git Kustomize Helm Operators Combining Tools Summary The Path to GitOps | 3 Contents 22 Chapter 4–Git Argo CD can also work with Helm [2.2] and Kustomize [2.3] to render the YAML produced by those tools before applying them to the Kubernetes cluster. (We’ll look at Helm and Kustomize more closely in that Flux uses the Helm Golang [2.6] package. Flux doesn’t render the YAML, but instead deals with Helm directly. This design gives users a familiar feel if they are already using Helm often. Originally
