Kustomize

Even though the kustomization.yaml from Kustomize deployments are not really Kubernetes resources (as they are not really deployed), they have the same structure as Kubernetes resources. This also means that the kustomization.yaml can define metadata and annotations. Through these annotations, additional behavior on the deployment can be controlled.

Example:

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

metadata:
  annotations:
    kluctl.io/barrier: "true"
    kluctl.io/wait-readiness: "true"

resources:
  - deployment.yaml

kluctl.io/barrier

If set to true, kluctl will wait for all previous objects to be applied (but not necessarily ready). This has the same effect as barrier from deployment projects.

kluctl.io/wait-readiness

If set to true, kluctl will wait for readiness of all objects from this kustomization project. Readiness is defined the same as in hook readiness .
