Creating Kubernetes Pod per Kubernetes Job and Cleanup - kubernetes

Question

I'm trying to create Kubernetes job with the following requirements:
Only one pod can be created for each job at most
If the pod failed - the job will fail
Max run time of the pod will be 1 hour
If the job finished successfully - delete the job
I tried the following configurations:
apiVersion: batch/v1
kind: Job
metadata:
name: {{ .Release.Name }}
annotations:
"helm.sh/hook": post-install
"helm.sh/hook-delete-policy": hook-succeeded
spec:
template:
spec:
containers:
- name: {{ .Release.Name }}
image: {{ .Values.image }}
env:
- name: ARG1
value: {{ required "ARG1 is mandatory" .Values.ENV.ARG1 }}
- name: GITLAB_USER_EMAIL
value: {{ .Values.ENV.GITLAB_USER_EMAIL }}
envFrom:
- secretRef:
name: {{ .Release.Name }}
restartPolicy: Never
backoffLimit: 1
activeDeadlineSeconds: 3600
But it's not working as expected, any ideas?
Thanks !

Only one pod can be created for each job at most
The requested parallelism (.spec.parallelism) can be set to any non-negative value. If it is unspecified, it defaults to 1. If it is specified as 0, then the Job is effectively paused until it is increased.
For Cronjobs could be helpful successfulJobsHistoryLimit: 0, failedJobsHistoryLimit: 0 this will
remove the PODs if it's get failed or success so no history or
POD will stays. So only one pod will get created or run.
If the pod failed - the job will fail
That will be the default behavior, also restartPolicy: Never so it won't get restarted.
Max run time of the pod will be 1 hour
activeDeadlineSeconds: 3600 you have already added
If the job finished successfully - delete the job
ttlSecondsAfterFinished: 100 will solve your issue.
