Dynamic variable use in kustomize yaml

Helm-Kustomize
#1

Hi Team,

May I know how to use the dynamic variable in kustomize file?

requesting to get the cluster name and update the value.yaml file. before converting the file as secret in argocd?

Example:-

#cat kustomization.yaml
apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization

generatorOptions:
disableNameSuffixHash: true

secretGenerator:

  • name: fluent-data-values
    namespace: fluentd
    files:
    • values.yml

resources:

  • deployment.yaml

=============================
#cat values.yml
namespace: “fluentd”
fluent:
config:
service: |
@SET cluster= k8sclustername # replace this k8sclustername from "kubectl get nodes -o=json| jq '.items[0].metadata.annotations."cluster.x-k8s.io/cluster-name"'"

Its personal project.

The kustomize file have value.yaml for generate the secret. The dynamic variable need to update in value.yaml file before generate the secret.

“kubectl get nodes -o=json| jq '.items[0].metadata.annotations.”[cluster.x-k8s.io/cluster-name"'"]

===============
secretGenerator:

  • name: fluent-data-values
    namespace: fluentd
    files:
    • values.yml
      ============

#cat values.yml
namespace: “fluentd”
fluent:
config:
service: |
@SET cluster= k8sclustername # replace this k8sclustername from "kubectl get nodes -o=json| jq '.items[0].metadata.annotations."cluster.x-k8s.io/cluster-name"'"
