Closes: OCPBUGS-112465

- What I did
This updates the MachineOSBuild event and condition setting functions to handle pod building failures that will retry.

- How to verify it

  1. Launch a 5.1 cluster with this PR included.
  2. Enable OCL in a pool with a MachineOSConfig that will cause a MachineOSBuild failure. An example of how to do this is below.
$ oc create secret docker-registry quay-push-secret \
    -n openshift-machine-config-operator \
    --docker-server=quay.io \
    --docker-username=<>
    --docker-password=<>
$ oc create -f - << EOF
apiVersion: machineconfiguration.openshift.io/v1
kind: MachineConfigPool
metadata:
 name: layered
spec:
 machineConfigSelector:
  matchExpressions:
   - {key: machineconfiguration.openshift.io/role, operator: In, values: [worker,layered]}
 nodeSelector:
  matchLabels:
   node-role.kubernetes.io/layered: ""
EOF
$ oc label node <node> node-role.kubernetes.io/layered=
$ oc apply -f - << EOF
apiVersion: machineconfiguration.openshift.io/v1
kind: MachineOSConfig
metadata:
  name: layered
spec:
  machineConfigPool:
    name: layered
  containerFile:
  - containerfileArch: NoArch
    content: |-
      FROM configs AS final
      RUN dnf install -y nmap && \
        dnf clean all && \
        bootc container lint
  imageBuilder:
    imageBuilderType: Job
  renderedImagePushSecret:
    name: quay-push-secret
  renderedImagePushSpec: "quay.io/<repo-path>:ocl-testing"
EOF
  1. Track the MachineOSBuild events and status conditions to ensure information is clearly reflected to users.
$ oc get machineosbuild

Pipeline controller notification
This repo is configured to use the pipeline controller. Second-stage tests will be triggered either automatically or after lgtm label is added, depending on the repository configuration. The pipeline controller will automatically detect which contexts are required and will utilize /test Prow commands to trigger the second stage.

For optional jobs, comment /test ? to see a list of all defined jobs. To trigger manually all jobs from second stage use /pipeline required command.

Walkthrough

The build controller adds error-level logs for status evaluation, job updates, status lookups, reconciliation decisions, condition checks, and terminal-state evaluation. Existing behavior remains unchanged.

Changes

Build diagnostics

Layer / File(s) Summary
State and condition evaluation diagnostics
pkg/apihelpers/machineosbuild.go, pkg/controller/build/helpers.go, pkg/controller/common/mos_state.go
Logs condition inputs, transition paths, derived states, terminal-state checks, and build condition comparisons without changing behavior.
Job and build reconciliation diagnostics
pkg/controller/build/reconciler.go
Logs job updates, configuration lookups, status retrieval failures, retry handling, and status update decisions. The update-decision log uses general-value formatting.
Job status fixture diagnostics
pkg/controller/build/fixtures/helpers.go
Logs supplied job status fields before the existing job status update.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: 🟡 Moderate · up to 8e161

The PR adds reconciliation diagnostics that can expose full status content and emit error-level records on expected paths, creating a concrete logging/privacy and signal-quality risk in production. It should not be merged until the logs are redacted and downgraded to verbosity-gated informational output.


Important

Pre-merge checks failed

Please resolve all errors before merging. Addressing warnings is optional.

❌ Failed checks (1 error, 2 warnings)

Check name Status Explanation Resolution
No-Sensitive-Data-In-Logs ❌ Error New %v logs dump MachineOSBuildStatus, including DigestedImagePushSpec; its API permits customer registry hosts, including internal hostnames. Do not log whole statuses or conditions. Log only fixed state names and redacted identifiers, or explicitly sanitize image pullspec hosts and messages.
Docstring Coverage ⚠️ Warning Docstring coverage is 60.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 5 functions across 5 files. Write docstrings for the functions missing them to satisfy the coverage threshold.
Title check ⚠️ Warning The title describes functional handling of pod-failure retries, but the changes only add diagnostic logging and do not change event or condition behavior. Update the title to describe the added diagnostic logging for MachineOSBuild, job, and condition reconciliation.

Check name Status Explanation
Linked Issues check ✅ Passed Check skipped because no linked issues were found for this pull request.
Out of Scope Changes check ✅ Passed Check skipped because no linked issues were found for this pull request.
Stable And Deterministic Test Names ✅ Passed The origin/main...HEAD diff changes only five non-test Go files. It adds logging and comments, and introduces no It, Describe, Context, or When test titles.
Test Structure And Quality ✅ Passed The diff changes no Ginkgo test blocks or test waits; the fixture helper only adds logging, so no stated test-quality failure is introduced.
Microshift Test Compatibility ✅ Passed The PR diff changes only five existing Go implementation/helper files and adds no *_test.go files or Ginkgo declarations, so MicroShift test compatibility is not applicable.
Single Node Openshift (Sno) Test Compatibility ✅ Passed The diff against origin/main changes only five production/helper Go files; it adds no Ginkgo e2e tests, test files, or multi-node assumptions.
Topology-Aware Scheduling Compatibility ✅ Passed The diff changes only klog diagnostics, a comment, and whitespace; added lines contain no affinity, topology spread, replica, node-selector, toleration, or PDB constraints.
Ote Binary Stdout Contract ✅ Passed The diff adds klog calls only inside ordinary controller/helper methods. OTE main is unchanged, and its sole changed-package import uses only a constant; no affected call occurs in suite setup.
Ipv6 And Disconnected Network Test Compatibility ✅ Passed The pull request changes only five Go implementation/fixture-helper files; the diff adds no *_test.go or Ginkgo tests and contains no network or external-connectivity code.
No-Weak-Crypto ✅ Passed The PR diff adds logging, comments, and whitespace changes only; it introduces no MD5, SHA1, DES, RC4, 3DES, Blowfish, ECB, custom crypto, or secret comparisons.
Container-Privileges ✅ Passed The PR changes only five Go files. The diff adds no manifests or privilege settings such as privileged, hostPID, hostNetwork, hostIPC, SYS_ADMIN, or allowPrivilegeEscalation.

Closes: OCPBUGS-112465

- What I did
This updates the MachineOSBuild event and condition setting functions to handle pod building failures that will retry.

- How to verify it

  1. Launch a 5.1 cluster with this PR included.
  2. Enable OCL in a pool with a MachineOSConfig that will cause a MachineOSBuild failure. An example of how to do this is below.
$ oc create secret docker-registry quay-push-secret \
   -n openshift-machine-config-operator \
   --docker-server=quay.io \
   --docker-username=<>
   --docker-password=<>
$ oc create -f - << EOF
apiVersion: machineconfiguration.openshift.io/v1
kind: MachineConfigPool
metadata:
name: layered
spec:
machineConfigSelector:
 matchExpressions:
  - {key: machineconfiguration.openshift.io/role, operator: In, values: [worker,layered]}
nodeSelector:
 matchLabels:
  node-role.kubernetes.io/layered: ""
EOF
$ oc label node <node> node-role.kubernetes.io/layered=
$ oc apply -f - << EOF
apiVersion: machineconfiguration.openshift.io/v1
kind: MachineOSConfig
metadata:
 name: layered
spec:
 machineConfigPool:
   name: layered
 containerFile:
 - containerfileArch: NoArch
   content: |-
     FROM configs AS final
     RUN dnf install -y nmap && \
       dnf clean all && \
       bootc container lint
 imageBuilder:
   imageBuilderType: Job
 renderedImagePushSecret:
   name: quay-push-secret
 renderedImagePushSpec: "quay.io/<repo-path>:ocl-testing"
EOF
  1. Track the MachineOSBuild events and status conditions to ensure information is clearly reflected to users.
$ oc get machineosbuild
