CronJob creation fails during fabric8:apply goal

[smoyer64]

FMP accepts a manifest (or template) for a kind: CronJob but fails to deploy it to the Kubernetes cluster. Apparently the kubernetes-client library used by FMP doesn't support CronJob yet, so while FMP processes it, pushing it to the cluster causes the following error:

[ERROR] Failed to execute goal io.fabric8:fabric8-maven-plugin:3.5.38:apply (deploy) on project academics-student-importer: Failed to create CronJob from kubernetes.yml. io.fabric8.kubernetes.client.KubernetesClientException: No handler found for object:CronJob(
<the generated manifest>), status=null, additionalProperties={}) -> [Help 1]

See fabric8io/kubernetes-client#1018 for the kubernetes-client roadmap

@smoyer64 : Hi, Do you use CronJobs with v2alpha or v1beta1? Actually, I pushed a change in kubernetes-client for using v1beta1 for CronJob. And after this release of kubernetes-client, we will upgrade fmp to latest kubernetes-client.

Here's the (slightly anonymized) YAML for several of our projects:

apiVersion: batch/v1beta1
kind: CronJob
metadata:
  name: application-importer
spec:
  schedule: "*/5 * * * *"
  jobTemplate:
    spec:
      template:
        spec:
          containers:
          - name: application-importer
            image: application-importer:${timestamp}
            imagePullPolicy: IfNotPresent
            envFrom:
            - configMapRef:
                name: application-config
            - secretRef:
                name: application-secret
          restartPolicy: Never

@smoyer64 : okay, I see you're using v1beta1. Cool ;-) . Thanks for your feedback

Since fmp now has latest kubernetes client i.e v4.0.4, this issue can be closed ;-)
