Is it possible to have a dynamic namePrefix/nameSuffix in kustomize?

In Helm, it is possible to specify a release name using

helm install my-release-name chart-path

This means, I can specify the release name and its components (using fullname) using the CLI.

In kustomize (I am new to kustomize), there is a similar concept, namePrefix and nameSuffix which can be defined in a kustomization.yaml

apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization

namePrefix: overlook-

resources:
- deployment.yaml

However, this approach needs a custom file, and using a "dynamic" namePrefix would mean that a kustomization.yaml has to be generated using a template and kustomize is, well, about avoiding templating.

Is there any way to specify that value dynamically?

You can use kustomize edit to edit the nameprefix and namesuffix values.

For example:

Deployment.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: the-deployment
spec:
  replicas: 5
  template:
    containers:
      - name: the-container
        image: registry/conatiner:latest

Kustomization.yaml

apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization

resources:
- deployment.yaml

Then you can run kustomize edit set nameprefix dev- and kustomize build . will return following:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: dev-the-deployment
spec:
  replicas: 5
  template:
    containers:
    - image: registry/conatiner:latest
      name: the-container
