Kustomize Integration

kluctl uses kustomize to render final resources. This means, that the finest/lowest level in kluctl is represented with kustomize deployments. These kustomize deployments can then perform further customization, e.g. patching and more. You can also use kustomize to easily generate ConfigMaps or secrets from files.

Generally, everything is possible via kustomization.yaml, is thus possible in kluctl.

We advise to read the kustomize reference . You can also look into the official kustomize example .

One way you might use this is to Kustomize a set of manifests from an external project.

For example:

# deployment.yml
deployments:
- git: git@github.com/example/example.git
  onlyRender: true
- path: kustomize_example

# kustomize_example/kustomization.yml
---
apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization
bases:
  - ../example
patches:
  - # your patches here
