Commit: d0f68cb9b0e4f1b45a871859edd5b5517ce6c339 (Oliver Meyer) coder/coder@d0f68cb
Failure Date: 2026-06-29

What failed:

• gen job: ./scripts/check_unstaged.sh reported unstaged changes in Helm golden files
• test-go-pg, test-go-pg-17, test-go-race-pg: helm/coder/tests TestRenderChart subtests
  • TestRenderChart/default/listenerset
  • TestRenderChart/default/listenerset_redirect
  • TestRenderChart/coder/listenerset

Key error output:

• gen job:

  • Unstaged changes in:
    • helm/coder/tests/testdata/listenerset.golden
    • helm/coder/tests/testdata/listenerset_coder.golden
    • helm/coder/tests/testdata/listenerset_redirect.golden
    • helm/coder/tests/testdata/listenerset_redirect_coder.golden
  • Diff snippet (example):
    • name: CODER_CLUSTER_HOST
      valueFrom:
      fieldRef:
      fieldPath: status.podIP

• test-go-race-pg/test-go-pg/test-go-pg-17:

  • Expected vs actual diff adds the same env var:

    •    - name: CODER_CLUSTER_HOST
      

    •      valueFrom:
      

    •        fieldRef:
      

    •          fieldPath: status.podIP
      

Root Cause: Code change added CODER_CLUSTER_HOST to the helm chart output, but the listenerset* golden files were not regenerated/committed, so TestRenderChart comparisons and gen check_unstaged fail deterministically.

Assignment Analysis (per ownership rules):

• git log --oneline -10 helm/coder/templates/coder.yaml
  • d0f68cb9 feat: add listenerset (Oliver Meyer)
• git log --oneline -10 helm/coder/tests/testdata/listenerset.golden
  • d0f68cb9 feat: add listenerset (Oliver Meyer)
• git log --oneline -10 helm/coder/tests/chart_test.go
  • cd92220 feat(helm): add setting to disable service account creation (MaxTNielsen)

Most recent meaningful changes to the helm template and listenerset golden files are in d0f68cb9 (Oliver Meyer), so assigning to Ben Potter (co-author) for helm chart ownership triage.

Reproduction:

• go test ./helm/coder/tests -run TestRenderChart -count=1
• To fix: go test ./helm/coder/tests -update and commit updated golden files (also re-run make gen to verify clean working tree)

Related Issues:

• None found (searches: listenerset, CODER_CLUSTER_HOST, TestRenderChart, helm/coder/tests)

Failure Date: 2026-06-29

Key evidence:

• gen job (Check for unstaged files):
  • Unstaged changes in helm/coder/tests/testdata/listenerset*.golden
  • Diff snippet:

    •    - name: CODER_CLUSTER_HOST
      

    •      valueFrom:
      

    •        fieldRef:
      

    •          fieldPath: status.podIP
      

• test-go-race-pg/test-go-pg-17/test-go-pg (ubuntu-latest):
  • TestRenderChart/* listenerset variants fail with the same expected vs actual diff adding CODER_CLUSTER_HOST.

Notes:

• Searched race logs for "WARNING: DATA RACE"; none found. Failure is deterministic golden mismatch, same root cause as issue.
