In some scenarios when we interrupt a MOSB and we use the rebuild label in the MOSC to rebuild the interrupted MOSB, the image is never rebuilt.

Always
    

We add here the steps using the new API, it should be the same with the old API

    1. Create an infra pool
apiVersion: machineconfiguration.openshift.io/v1
kind: MachineConfigPool
metadata:
  name: infra
spec:
  machineConfigSelector:
    matchExpressions:
      - {key: machineconfiguration.openshift.io/role, operator: In, values: [worker,infra]}
  nodeSelector:
    matchLabels:
      node-role.kubernetes.io/infra: ""


    2. Create a MOSC for the infra pool
oc create -f - << EOF
apiVersion: machineconfiguration.openshift.io/v1
kind: MachineOSConfig
metadata:
  name: mosc-infra
spec:
  machineConfigPool:
    name: infra
  currentImagePullSecret:
    name: $(oc get secret -n openshift-config pull-secret -o json | jq "del(.metadata.namespace, .metadata.creationTimestamp, .metadata.resourceVersion, .metadata.uid, .metadata.name)" | jq '.metadata.name="pull-copy"' | oc -n openshift-machine-config-operator create -f - &> /dev/null; echo -n "pull-copy")

  imageBuilder:
    imageBuilderType: Job
  baseImagePullSecret:
    name: $(oc get secret -n openshift-config pull-secret -o json | jq "del(.metadata.namespace, .metadata.creationTimestamp, .metadata.resourceVersion, .metadata.uid, .metadata.name)" | jq '.metadata.name="pull-copy"' | oc -n openshift-machine-config-operator create -f - &> /dev/null; echo -n "pull-copy")
  renderedImagePushSecret:
    name: $(oc get secret -n openshift-config pull-secret -o json | jq "del(.metadata.namespace, .metadata.creationTimestamp, .metadata.resourceVersion, .metadata.uid, .metadata.name)" | jq '.metadata.name="pull-copy"' | oc -n openshift-machine-config-operator create -f - &> /dev/null; echo -n "pull-copy")
  renderedImagePushSpec: "quay.io/mcoqe/layering:ocl"
EOF

    3. Wait for the image to be created
    4. Delete the MOSC resource created in step 2
    5. Delete the infra pool
    6. Create a MOSC for the worker pool 
oc create -f - << EOF
apiVersion: machineconfiguration.openshift.io/v1
kind: MachineOSConfig
metadata:
  name: mosc-worker
spec:
  machineConfigPool:
    name: worker
  currentImagePullSecret:
    name: $(oc get secret -n openshift-config pull-secret -o json | jq "del(.metadata.namespace, .metadata.creationTimestamp, .metadata.resourceVersion, .metadata.uid, .metadata.name)" | jq '.metadata.name="pull-copy"' | oc -n openshift-machine-config-operator create -f - &> /dev/null; echo -n "pull-copy")

  imageBuilder:
    imageBuilderType: Job
  baseImagePullSecret:
    name: $(oc get secret -n openshift-config pull-secret -o json | jq "del(.metadata.namespace, .metadata.creationTimestamp, .metadata.resourceVersion, .metadata.uid, .metadata.name)" | jq '.metadata.name="pull-copy"' | oc -n openshift-machine-config-operator create -f - &> /dev/null; echo -n "pull-copy")
  renderedImagePushSecret:
    name: $(oc get secret -n openshift-config pull-secret -o json | jq "del(.metadata.namespace, .metadata.creationTimestamp, .metadata.resourceVersion, .metadata.uid, .metadata.name)" | jq '.metadata.name="pull-copy"' | oc -n openshift-machine-config-operator create -f - &> /dev/null; echo -n "pull-copy")
  renderedImagePushSpec: "quay.io/mcoqe/layering:ocl"
EOF

    7. Wait until the new Job is created and delete it to interrupt the MOSB resource

$ oc get machineosbuild
NAME                                           PREPARED   BUILDING   SUCCEEDED   INTERRUPTED   FAILED   AGE
mosc-infra-b9e2aca7838fb9be42ee2755c9ff35fc    False      False      True        False         False    8m
mosc-worker-2b5aaa0c9933f34e763039e753b7aefa   False      True       False       False         False    37s

    8. Add the rebuild label to rebuild the interrupted MOSB

$ oc patch machineosconfig mosc-worker --type json -p '[{"op": "add", "path": "/metadata/annotations/machineconfiguration.openshift.io~1rebuild", "value":""}]'
machineosconfig.machineconfiguration.openshift.io/mosc-worker patched




    

A new job is triggered, and then it is immediately terminated

$ l job
NAME                                                 STATUS        COMPLETIONS   DURATION   AGE
build-mosc-worker-2b5aaa0c9933f34e763039e753b7aefa   Terminating   0/1           21s        21s


The MOSB resources is recreated, but it is immediately reported as Interrupted again
$ oc get machineosbuild machineosbuild
NAME                                           PREPARED   BUILDING   SUCCEEDED   INTERRUPTED   FAILED   AGE
mosc-infra-b9e2aca7838fb9be42ee2755c9ff35fc    False      False      True        False         False    47m
mosc-worker-2b5aaa0c9933f34e763039e753b7aefa   False      False      False       True          False    119s

    

The MOSB resource should be rebuilt without problems
