helm cronjob multiple containers - yaml

Question

I need to run multiple containers in one cronjob execution. Currently I have the following cronjob.yaml template:
jobTemplate:
spec:
template:
metadata:
labels:
app: {{ .Release.Name }}
cron: {{ .Values.filesjob.jobName }}
spec:
containers:
- image: "{{ .Values.image.repository }}:{{ .Values.image.tag }}"
env:
- name: FILE_MASK
value: "{{ .Values.filesjob.fileMask }}"
- name: ID
value: "{{ .Values.filesjob.id }}"
imagePullPolicy: {{ .Values.image.pullPolicy }}
name: {{ .Values.filesjob.jobName }}
volumeMounts:
- mountPath: /data
name: path-to-clean
- name: path-logfiles
mountPath: /log
- image: "{{ .Values.image.repository }}:{{ .Values.image.tag }}"
env:
- name: FILE_MASK
value: "{{ .Values.filesjob.fileMask }}"
- name: ID
value: "{{ .Values.filesjob.id }}"
imagePullPolicy: {{ .Values.image.pullPolicy }}
name: {{ .Values.filesjob.jobName2 }}
volumeMounts:
- mountPath: /data
name: path2-to-clean
- name: path2-logfiles
mountPath: /log
The above generates a cronjob which executes two containers with passing different env variables. can I generate the same using values.yaml by iterating over a variable?

I was able to solve this basing on example from this article - https://nikhils-devops.medium.com/helm-chart-for-kubernetes-cronjob-a694b47479a
Here is my template:
{{- if .Values.cleanup.enabled -}}
apiVersion: batch/v1beta1
kind: CronJob
metadata:
name: registry-cleanup-job
namespace: service
labels:
{{- include "some.labels" . | nindent 4 }}
spec:
schedule: {{ .Values.cleanup.schedule }}
concurrencyPolicy: Forbid
successfulJobsHistoryLimit: 2
failedJobsHistoryLimit: 1
jobTemplate:
spec:
template:
spec:
containers:
{{- range .Values.cleanup.crons }}
- name: {{ .name | quote }}
image: {{ $.Values.cleanup.imageName }}
imagePullPolicy: {{ $.Values.cleanup.pullPolicy }}
args:
- {{ .command }}
{{- end}}
restartPolicy: Never
{{- end }}
And related values:
cleanup:
enabled: true
schedule: "0 8 * * 5"
imageName: digitalocean/doctl:1.60.0
pullPolicy: IfNotPresent
crons:
- command0:
name: "cleanup0"
command: command0
- command1:
name: "cleanup1"
command: command1
- command2:
name: "cleanup2"
command: command2
- command3:
name: "cleanup3"
command: command3
- command4:
name: "cleanup4"
command: command4
