Penny dropped - why is my job immutable ?

I'm tinkering with kube-bench at present, and wanted to deploy it as a Kubernetes Job using the job.yaml that's included with the repo.

However, my custom-built kube-bench image is stored in a private registry ( via IBM Container Registry ) so I needed to reference a Kubernetes Secret which I'd previously defined within my K8s cluster.

So far, so good ...

Having defined the Secret, I needed to reference it in the Job description ( job.yaml ) via an imagePullSecrets which I'd added to the YAML: -

---
apiVersion: batch/v1
kind: Job
metadata:
  name: kube-bench
spec:
  template:
    metadata:
      labels:
        app: kube-bench
    spec:
      hostPID: true
      imagePullSecrets:
        - name: mysecret
      containers:
        - name: kube-bench
          image: aquasec/kube-bench:latest
          command: ["kube-bench"]

However, when I tried to apply the YAML: -

kubectl apply -f job.yaml 

The Job "kube-bench" is invalid: spec.template: Invalid value: core.PodTemplateSpec{ObjectMeta:v1.ObjectMeta{Name:"", GenerateName:"", Namespace:"", SelfLink:"", UID:"", ResourceVersion:"",

What the heck ?

Then I read this: -


which says, in part: -

This is not a bug, you can't change the template after the job has been created.

Ah!!!

I listed my jobs: -

kubectl get jobs -A

So the job already exists - so how can I change the job description for an inflight job ?

Oh, yeah, I can just delete it ...

kubectl delete job kube-bench
