Kustomize Integration

Kustomize can be extended to understand CRD objects through the use of transformer configs. Using transformer configs, kustomize can be "taught" about the structure of a Rollout object and leverage kustomize features such as ConfigMap/Secret generators, variable references, and common labels & annotations. To use Rollouts with kustomize:

  1. Download rollout-transform.yaml into your kustomize directory.

  2. Include rollout-transform.yaml in your kustomize configurations section:

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

configurations:
- rollout-transform.yaml
With Kustomize 3.6.1 it is possible to reference the configuration directly from a remote resource:

configurations:
  - https://argoproj.github.io/argo-rollouts/features/kustomize/rollout-transform.yaml

A example kustomize app demonstrating the ability to use transformers with Rollouts can be seen here.
