How to migrate windows scheduled job(exe) to AKS?

Question

One on - premise enterprise application needs to be migrated to AKS. Multiple windows scheduled jobs need to be migrated to AKS. What is the best practice?

1. Should we keep it in AKS and schedule? if yes then how?
2. Should use any other Azure service to accomplish? if yes then how?
3. Can we use Control-M agent for that?

@Pratim Das, Partha C Firstly, apologies for the delay in responding on this and any inconvenience this issue may have caused.

Are workloads mentioned already running in containers as I suspect not based on the detail provided? If it isn’t then you can refer to this article.

There is not enough info to provide a good recommendation, however, have you looked at CronJob resource in k8s?

Here’s an example of such job definition:

apiVersion: batch/v1beta1  
kind: CronJob  
metadata:  
  name: {{ include "deploymentName" . }}  
  labels:  
{{ include "labels" . | indent 4 }}  
spec:  
  schedule: "0 */1 * * *" # Once an hour  
  concurrencyPolicy: Replace  
  jobTemplate:  
    spec:  
{{ include "retrieve-secrets-spec" . | indent 6 }}  

It includes below line:

{{- define "retrieve-secrets-spec" -}}  
template:  
  spec:  
    serviceAccountName: {{ .Values.keyvaultAgent.name }}  
    restartPolicy: OnFailure  
    {{- with .Values.keyvaultAgent.nodeSelector }}  
    nodeSelector:  
    {{- toYaml . | nindent 6 }}  
    {{- end }}  
    imagePullSecrets:  
      - name: "{{ .Values.keyvaultAgent.image.pullSecret }}"  
    containers:  
      - name: keyvault-agent  
        image: "{{ .Values.keyvaultAgent.image.repository }}:{{ .Values.keyvaultAgent.image.tag }}"  
        imagePullPolicy: {{ .Values.keyvaultAgent.image.pullPolicy }}  
        env:  
          - name: SERVICE_PRINCIPLE_FILE_PATH  
            value: /host/azure.json  
          - name: VAULT_BASE_URL  
            value: "{{ .Values.keyvaultAgent.vaultBaseUrl }}"  
          - name: CREATE_KUBERNETES_SECRETS  
            value: "true"  
          - name: SECRETS_NAMESPACE  
            value: "{{ .Values.keyvaultAgent.secretsNamespace }}"  
          - name: SECRETS_FOLDER  
            value: /secrets  
          - name: SECRETS_KEYS  
            value: "{{ .Values.keyvaultAgent.secretNames}}"  
          - name: SECRETS_TYPE  
            value: "kubernetes.io/tls"  
        volumeMounts:  
          - name: host-sp  
            mountPath: /host  
            readOnly: true  
    volumes:  
      - name: host-sp  
        hostPath:  
          # this file contains the cluster service-principal, it exists on every node by default  
          path: /etc/kubernetes  
{{- end -}}
