Helm Update

Apply changes to the Bifrost Helm chart, keep it in sync with config.schema.json, and update all changelogs.

Workflow

Step 1: Gather Current State

Read the current helm chart version and identify the last helm release commit:

# Current helm chart version
cat helm-charts/bifrost/Chart.yaml | grep '^version:'

# Latest docs helm changelog (= last released version)
ls -1t docs/changelogs/helm-v*.mdx | head -1

# Find the commit that added the latest helm changelog
LAST_HELM_MDX=$(ls -1t docs/changelogs/helm-v*.mdx | head -1)
git log --oneline -- "$LAST_HELM_MDX" | head -1

Save the last-release commit SHA — you'll need it to scope the config.schema.json diff.

Step 2: Check config.schema.json Changes Since Last Helm Release

LAST_COMMIT=$(git log --oneline -- "$(ls -1t docs/changelogs/helm-v*.mdx | head -1)" | awk '{print $1}')

# What changed in config.schema.json since then?
git diff ${LAST_COMMIT}..HEAD -- transports/config.schema.json

Identify any fields added, removed, or changed in config.schema.json that are not yet reflected in the helm chart. These are gaps that must be closed — even if the user did not explicitly ask for them. Note each gap; you will apply them alongside the user's requested changes.

Step 3: Apply User-Requested Changes + Fill Gaps

For every change (user-requested AND schema gaps detected in Step 2):

values.yaml

Add new fields as commented-out blocks with a realistic sample value. Place new sections near related existing fields. Keep existing uncommented defaults intact.

# bifrost.newFeature.someField -- brief description
# someField: "example-value"

values.schema.json

Add a matching JSON schema property with:

• Correct type (string/boolean/integer/object/array)
• description matching the config.schema.json description (paraphrased concisely)
• Any enum, default, minimum/maximum, or nested properties/items needed
• Mark required fields in the parent object's required array if mandatory

Locate the correct parent path in values.schema.json by searching for the nearest ancestor field.

_helpers.tpl

Wire new values into the generated config.json block inside {{- define "bifrost.config" -}}. Follow the existing rendering patterns:

• Simple scalar: {{- if .Values.bifrost.someField }} → emit "some_field": {{ .Values.bifrost.someField | toJson }}
• Optional block: wrap in {{- if ... }} / {{- end }}
• Duration strings: pass through toJson unchanged
• env.VAR_NAME references: pass through toJson unchanged

Search the existing template for a nearby field to find the right insertion point.

Step 4: Determine New Helm Chart Version

Read helm-charts/bifrost/Chart.yaml. Increment the patch version (third number) unless the scope of changes clearly warrants a minor bump. Ask the user if unsure:

Current: 2.1.27  →  New: 2.1.28

Update Chart.yaml:

version: 2.1.28   # updated line

Step 5: Update Helm README

File: helm-charts/bifrost/README.md

5a. Bump "Latest Version" line

Find and update:

**Latest Version:** 2.1.27

→

**Latest Version:** 2.1.28

5b. Update the Upcoming section

Look for an ### Upcoming section immediately after the ## Changelog heading. If it does not exist, insert one. On every run, append bullet points for the current changes to ### Upcoming — do not create a new versioned heading; that happens at release time.

Structure:

## Changelog

### Upcoming

- Brief bullet describing what was added/changed. Reference the values.yaml path (e.g. `bifrost.foo.bar`) and the config.json field it renders into (`foo_bar`). One bullet per logical change.

### 2.1.27
...existing entries...

Keep bullets concise — one line each. No paragraph prose. Mirror the style of existing changelog entries.

Step 6: Create Docs MDX Changelog

Create a new file docs/changelogs/helm-v<NEW_VERSION>.mdx:

---
title: "v<NEW_VERSION>"
description: "Helm v<NEW_VERSION> changelog - <YYYY-MM-DD>"
---

<Update label="Bifrost Helm" description="v<NEW_VERSION>">

## Changelog

- <bullet 1 — same content as README Upcoming bullets>
- <bullet 2>
...

</Update>

Use today's date (2026-07-10 or whatever the current date is). Mirror the bullet style from docs/changelogs/helm-v2.1.26.mdx.

Step 7: Update docs.json Navigation

In docs/docs.json, find the "item": "Helm" group (under changelogs). Prepend the new entry at the top of its pages array:

"pages": [
  "changelogs/helm-v2.1.28",   ← insert here
  "changelogs/helm-v2.1.27",
  ...
]

Step 8: Final Diff Review (Correctness Check)

After all edits, run a fresh perspective check:

git diff -- helm-charts/bifrost/values.yaml helm-charts/bifrost/values.schema.json helm-charts/bifrost/templates/_helpers.tpl

For every new field in the diff, verify:

1. values.yaml — field exists (commented out with sample value)
2. values.schema.json — matching property with correct type and description
3. _helpers.tpl — field is rendered into config.json output under the correct JSON key
4. config.schema.json counterpart — confirm the JSON key emitted by _helpers.tpl exists in transports/config.schema.json (or is a known helm-only field like replicaCount)

If any field fails check 4, either fix the mapping or flag it to the user explicitly.

Report a short table:

Common Rendering Patterns in _helpers.tpl

{{/* Simple optional string */}}
{{- if .Values.bifrost.server.readBufferSize }}
"read_buffer_size": {{ .Values.bifrost.server.readBufferSize | toJson }},
{{- end }}

{{/* Optional boolean */}}
{{- if hasKey .Values.bifrost.loadBalancer "directionSelectionEnabled" }}
"direction_selection_enabled": {{ .Values.bifrost.loadBalancer.directionSelectionEnabled | toJson }},
{{- end }}

{{/* Nested object — only emit if any subfield set */}}
{{- if .Values.bifrost.newFeature }}
"new_feature": {
  {{- if .Values.bifrost.newFeature.timeout }}
  "timeout": {{ .Values.bifrost.newFeature.timeout | toJson }},
  {{- end }}
},
{{- end }}

Important Rules

• Never omit the ### Upcoming section after Step 5 — always ensure it exists and is populated.
• Never promote ### Upcoming to a versioned heading — that is done by the changelog-writer skill at release time.
• Never write values.yaml fields as uncommented unless they were already uncommented (i.e., they are mandatory defaults like replicaCount).
• Always verify config.schema.json mapping in the final diff review.
• If a config.schema.json gap is found but its helm mapping would be complex (e.g. a new top-level plugin system), flag it to the user rather than silently skipping.
• Keep changelog bullets brief: one line, what was added/changed, what values.yaml path, what config.json key it renders into.
