I have a simple helm chart with a Deployment and Job Object

apiVersion: apps/v1
kind: Deployment
metadata:
  name: {{ .Release.Name }}-parent
spec:
  selector:
    matchLabels:
      app: {{ .Release.Name }}-parent
  template:
    metadata:
      labels:
        app: {{ .Release.Name }}-parent
    spec:
      containers:
        - name: nginx
          image: nginx:latest
          
          # Add other container configuration as needed

and the job object

apiVersion: batch/v1
kind: Job
metadata:
  name: {{ .Release.Name }}-job
  ownerReferences:
    - apiVersion: apps/v1
      blockOwnerDeletion: true
      controller: true
      kind: Deployment
      name: {{ .Release.Name }}-parent
      uid: $(kubectl get deployment my-release-parent -o jsonpath='{.metadata.uid}')
spec:
  template:
    metadata:
      labels:
        app: {{ .Release.Name }}-job
    spec:
      containers:
        - name: busybox
          image: busybox:latest
      restartPolicy: Never
          # Add other container configuration as needed
      # Add other Job configuration as needed

I’m trying to dynamically parse the UID of the deployment object as the onwnerReference in the job manifest. Right now, if I deploy this chart, everything works fine except for the job that wont get deployed. When I remove the ownerReference from the job manifest, the job deploys perfectly, so I know the issue has to do with the way I parsed the UID…

I want a situation that whenever i delete my deployment, it deletes all the child resources. See more: onwerReference

i tried different ways to dynamically parse the UID, and this codes works if i directly run the commands after the deployment.

kubectl get deployment deploymentexample -o yaml | grep uid | cut -d ’ ’ -f 4

kubectl get deployment my-release-parent -o jsonpath=‘{.metadata.uid}’
