Managing Kubernetes Resources with Kustomize

Helm is the de-facto standard for managing groups of Kubernetes resources that belong to an application as a package. It comes with its own ecosystem to build, configure and distribute these packages. In some cases, this is an appropriate approach but sometimes we just want to manage our resources as yaml files and need a simple way to slightly modify the resources for different environments. In this article we will have a look at how Kustomize can help us with this.
