Hello Everyone and Let’s get start with the new blog on Kustomize.
Welcome to the new blog where we are going to introduce a new topic in the field of deployment technology called Kustomize or Kustomization
Introduction to Kustomize
deployment, services, configMaps and many more for multiple domains or environments without changing the actual
Kubernetes manifest files.
It works on the base and overlays approach where we have a base where we have all the manifest files of Kubernetes
and in overlays, we have multiple defined files that can be configured for each environment as well.
Concept of Kustomization

Like, we have:-
And also, we have
Kustomization.yml which stores all the resource files which is or can be needed to changed as per the
In overlays, we use patches to modify the configuration of Kubernetes manifest files. It consists of:
patches: - target: kind: Deployment name: test-deployment patch: |- - op: replace path: /spec/replicas value: 3
Similarly, we can use other configuration files like deployment, configMap, services and many more for different environments so that we can deploy the application across various domains.
