DevContainer User f2b0e4c66f fix: use softprops/action-gh-release instead of gh CLI
gh CLI is not installed on the self-hosted runner. Switch to
softprops/action-gh-release@v2 which was used before the
standardization broke it.

DevContainer User a46d0e7519 fix: handle tarball already having correct name in release workflow
The headlamp-plugin package command already produces a tarball named
{pkg}-{version}.tar.gz, so the mv command fails when source and
destination are the same file.

Chris Farhood 24033ca977 docs: remove incorrect watchPlugins: false references
Remove all references to the incorrect `config.watchPlugins: false`
requirement that was believed necessary for Headlamp v0.39.0+.

Investigation revealed that plugins work correctly with the default
`watchPlugins: true` setting. The earlier documentation was based on
a misunderstanding of the plugin loading mechanism.

Changes:
- Remove watchPlugins: false from all YAML configuration examples
- Remove warning sections about watchPlugins requirement
- Update troubleshooting guides to focus on actual issues
- Simplify installation instructions by removing unnecessary config

Files updated:
- README.md (main installation docs and troubleshooting table)
- docs/DEPLOYMENT.md
- docs/TROUBLESHOOTING.md
- docs/getting-started/* (quick-start, installation, prerequisites)
- docs/deployment/* (helm, production)
- docs/troubleshooting/* (common-issues, README)
- Multiple other doc files formatted by prettier

This cleanup ensures ArtifactHub and GitHub documentation show
correct, simplified installation instructions.

Chris Farhood e884894840 ci: consolidate release workflow into single step
Merged prepare-release and release workflows into a single workflow
that handles everything in one job. This eliminates the need for
separate tokens or manual intervention.

Single workflow now:
- Validates version format
- Updates package.json and artifacthub-pkg.yml
- Builds and packages plugin
- Computes checksum
- Updates metadata with real checksum
- Commits all changes to main
- Creates and pushes tag
- Creates GitHub release with tarball

No more tag push triggers, no separate tokens needed.
Everything runs in one workflow_dispatch job.

2026-02-12 15:19:22 -05:00
Chris Farhood e62fba9cc1 ci: use GitHub App token to enable automatic workflow triggering
The prepare-release workflow now uses GH_APP_TOKEN instead of
GITHUB_TOKEN to push commits and tags. This allows the tag push
to automatically trigger the release workflow without manual
intervention.

GITHUB_TOKEN cannot trigger other workflows due to GitHub's
security policy to prevent infinite workflow loops.

Added documentation in .github/GH_APP_TOKEN.md explaining the
token setup and requirements.

Chris Farhood cdc1ce0303 ci: overhaul release workflow to eliminate manual steps and tag manipulation
Replace complex draft/publish release workflow with clean two-workflow approach:

1. prepare-release.yaml (manual workflow_dispatch)
   - Validates version format
   - Updates package.json and artifacthub-pkg.yml
   - Commits to main
   - Creates and pushes tag
   - Triggers release workflow automatically

2. release.yaml (automatic on tag push)
   - Single build-and-release job
   - Creates GitHub release with tarball in one step (no draft/publish)
   - Separate update-metadata job runs after release
   - Updates checksum on main branch

Benefits:
- No manual tarball upload required
- No tag force-push anti-pattern
- No draft/publish asset attachment failures
- Clear separation of concerns
- Self-documenting workflow

Eliminates:
- Guard logic for infinite loop prevention
- Post-release tag manipulation
- Manual intervention after workflow "succeeds"
- Checksum chicken-and-egg problem

name: agent-installer
description: Use this agent when the user wants to discover, browse, or install Claude Code agents from the awesome-claude-code-subagents repository.
tools: Bash, WebFetch, Read, Write, Glob
model: haiku
---
You are an agent installer that helps users browse and install Claude Code agents from the awesome-claude-code-subagents repository on GitHub.
## Your Capabilities
You can:
1. List all available agent categories
2. List agents within a category
3. Search for agents by name or description
4. Install agents to global (~/.claude/agents/) or local (.claude/agents/) directory
5. Show details about a specific agent before installing
6. Uninstall agents
## GitHub API Endpoints
- Categories list: `https://api.github.com/repos/VoltAgent/awesome-claude-code-subagents/contents/categories`
- Agents in category: `https://api.github.com/repos/VoltAgent/awesome-claude-code-subagents/contents/categories/{category-name}`
- Raw agent file: `https://raw.githubusercontent.com/VoltAgent/awesome-claude-code-subagents/main/categories/{category-name}/{agent-name}.md`
## Workflow
### When user asks to browse or list agents:
1. Fetch categories from GitHub API using WebFetch or Bash with curl
2. Parse the JSON response to extract directory names
3. Present categories in a numbered list
4. When user selects a category, fetch and list agents in that category
### When user wants to install an agent:
1. Ask if they want global installation (~/.claude/agents/) or local (.claude/agents/)
2. For local: Check if .claude/ directory exists, create .claude/agents/ if needed
3. Download the agent .md file from GitHub raw URL
4. Save to the appropriate directory
5. Confirm successful installation
### When user wants to search:
1. Fetch the README.md which contains all agent listings
2. Search for the term in agent names and descriptions
3. Present matching results
## Example Interactions
**User:** "Show me available agent categories"
**You:** Fetch from GitHub API, then present:
```
Available categories:
1. Core Development (11 agents)
2. Language Specialists (22 agents)
3. Infrastructure (14 agents)
...
```
**User:** "Install the python-pro agent"
**You:**
1. Ask: "Install globally (~/.claude/agents/) or locally (.claude/agents/)?"
2. Download from GitHub
3. Save to chosen directory
4. Confirm: "✓ Installed python-pro.md to ~/.claude/agents/"
**User:** "Search for typescript"
**You:** Search and present matching agents with descriptions
## Important Notes
- Always confirm before installing/uninstalling
- Show the agent's description before installing if possible
- Handle GitHub API rate limits gracefully (60 requests/hour without auth)
- Use `curl -s` for silent downloads
- Preserve exact file content when downloading (don't modify agent files)
## Communication Protocol
- Be concise and helpful
- Use checkmarks (✓) for successful operations
- Use clear error messages if something fails
- Offer next steps after each action

## K8s Module
```typescript
import { K8s } from '@kinvolk/headlamp-plugin/lib';
```
### KubeObject Base Class
```typescript
class KubeObject<T extends KubeObjectInterface> {
jsonData: T; // Raw K8s JSON — use this for spec/status access
metadata: KubeMetadata;
kind: string;
getAge(): string;
getName(): string;
getNamespace(): string | undefined;
delete(force?: boolean): Promise<void>;
patch(body: RecursivePartial<T>): Promise<void>;
static useGet(name?, namespace?): [item: T | null, error: ApiError | null];
static useList(opts?: { namespace?: string }): [items: T[], error: ApiError | null, loading: boolean];
static apiEndpoint: ApiClient | ApiWithNamespaceClient;
static className: string;
}
```
**CRITICAL**: Resource hooks return class instances. Raw K8s JSON lives under `.jsonData`. Access fields via `.jsonData.spec`, `.jsonData.status`, or typed getters.
### ResourceClasses
All standard K8s resource types available (Secret, Namespace, Pod, etc.):
```typescript
const [secrets, error, loading] = K8s.ResourceClasses.Secret.useList({ namespace: 'default' });
const [secret, error] = K8s.ResourceClasses.Secret.useGet('my-secret', 'default');
```
---
## ApiProxy
```typescript
import { ApiProxy } from '@kinvolk/headlamp-plugin/lib';
ApiProxy.request(
path: string,
options?: {
method?: 'GET' | 'POST' | 'PUT' | 'PATCH' | 'DELETE';
body?: string; // JSON.stringify'd
isJSON?: boolean; // false for non-JSON (logs, metrics)
headers?: Record<string, string>;
}
): Promise<unknown>
// CRD endpoint factories
ApiProxy.apiFactoryWithNamespace(group, version, resource): ApiWithNamespaceClient
ApiProxy.apiFactory(group, version, resource): ApiClient
```
**Service proxy URL** (accessing in-cluster services):
```
/api/v1/namespaces/${ns}/services/http:${name}:${port}/proxy${path}
```
---
## CommonComponents
From `@kinvolk/headlamp-plugin/lib/CommonComponents`:
`SectionBox` — container with title and optional `headerProps.actions`
`SectionHeader` — standalone header with title and actions array
`SectionFilterHeader` — header with namespace filter; `noNamespaceFilter` to hide it; `actions` array
`StatusLabel` — status chip; `status`: `'success' | 'error' | 'warning' | 'info'`
`Link` — internal nav; `routeName` + `params` object
`Loader` — spinner with `title` prop
`PercentageBar` — bar chart with `data` array of `{ name, value, fill }`
### SimpleTable (non-obvious props)
```typescript
<SimpleTable
data={items}
columns={[
{ label: 'Name', getter: (item) => item.metadata.name },
{ label: 'Status', getter: (item) => <StatusLabel status="success">Ready</StatusLabel> },
]}
emptyMessage="No items found."
/>
```
### NameValueTable (non-obvious props)
```typescript
<NameValueTable
rows={[
{ name: 'Key', value: 'display value' },
{ name: 'Hidden', value: 'x', hide: true },
]}
/>
```
### ConfigStore
```typescript
import { ConfigStore } from '@kinvolk/headlamp-plugin/lib';
const store = new ConfigStore<MyConfig>('plugin-name');
store.get(): MyConfig;
store.update(partial: Partial<MyConfig>): void;
store.useConfig(): () => MyConfig;
```
### Pre-bundled (no package.json entry needed)
react, react-dom, react-router-dom, @iconify/react, react-redux, @material-ui/core, @material-ui/styles, lodash, notistack, recharts, monaco-editor
---
## CRD Class Pattern
```typescript
import { ApiProxy, K8s } from '@kinvolk/headlamp-plugin/lib';
const { apiFactoryWithNamespace } = ApiProxy;
const { KubeObject } = K8s.cluster;
type KubeObjectInterface = K8s.cluster.KubeObjectInterface;
interface MyResourceInterface extends KubeObjectInterface {
spec: MySpec;
status?: MyStatus;
}
export class MyResource extends KubeObject<MyResourceInterface> {
static apiEndpoint = apiFactoryWithNamespace('mygroup.io', 'v1', 'myresources');
static get className(): string { return 'MyResource'; }
get spec(): MySpec { return this.jsonData.spec; }
get status(): MyStatus | undefined { return this.jsonData.status; }
}
```
---
## Plugin Entry Point Pattern
```typescript
// 1. Sidebar (parent → children)
registerSidebarEntry({ parent: null, name: 'my-plugin', label: 'My Plugin', icon: 'mdi:icon', url: '/mypath' });
registerSidebarEntry({ parent: 'my-plugin', name: 'my-list', label: 'Resources', url: '/mypath' });
// 2. Routes wrapped in ApiErrorBoundary
registerRoute({
path: '/mypath/:namespace?/:name?',
sidebar: 'my-list',
component: () => <ApiErrorBoundary><MyListPage /></ApiErrorBoundary>,
exact: true, name: 'my-resource',
});
// 3. Detail injection wrapped in GenericErrorBoundary
registerDetailsViewSection(({ resource }) => {
if (resource?.kind !== 'Secret') return null;
return <GenericErrorBoundary><MySection resource={resource} /></GenericErrorBoundary>;
});
// 4. Settings
registerPluginSettings('my-plugin', SettingsPage, true);
```
---
## Headlamp Test Mocks
```typescript
vi.mock('@kinvolk/headlamp-plugin/lib', () => ({
ApiProxy: { request: vi.fn().mockResolvedValue({}) },
K8s: { ResourceClasses: {}, cluster: { KubeObject: class {} } },
}));
vi.mock('@kinvolk/headlamp-plugin/lib/CommonComponents', () => ({
SectionBox: ({ children, title }: any) => <div data-testid="section-box">{title}{children}</div>,
SimpleTable: ({ data, columns }: any) => (
<table><tbody>{data.map((d: any, i: number) =>
<tr key={i}>{columns.map((c: any, j: number) => <td key={j}>{c.getter(d)}</td>)}</tr>
)}</tbody></table>
),
NameValueTable: ({ rows }: any) => (
<dl>{rows.filter((r: any) => !r.hide).map((r: any) =>
<div key={r.name}><dt>{r.name}</dt><dd>{r.value}</dd></div>
)}</dl>
),
StatusLabel: ({ children, status }: any) => <span data-status={status}>{children}</span>,
Link: ({ children }: any) => <a>{children}</a>,
Loader: ({ title }: any) => <div data-testid="loader">{title}</div>,
}));
```
---
## Theming & Dark Mode
Headlamp supports light and dark themes. **Never hardcode colors.** Use CSS custom properties with light-mode fallbacks:
### Required CSS variables for inline styles
```typescript
// Text
color: 'var(--mui-palette-text-primary)'
color: 'var(--mui-palette-text-secondary, #666)'
// Backgrounds
backgroundColor: 'var(--mui-palette-background-default, #fafafa)'
backgroundColor: 'var(--mui-palette-background-paper, #fff)'
// Borders
border: '1px solid var(--mui-palette-divider, #e0e0e0)'
// Interactive
backgroundColor: 'var(--mui-palette-primary-main, #1976d2)'
color: 'var(--mui-palette-primary-contrastText, #fff)'
// Disabled states
backgroundColor: 'var(--mui-palette-action-disabledBackground, #e0e0e0)'
color: 'var(--mui-palette-action-disabled, #9e9e9e)'
// Links
color: 'var(--link-color, #1976d2)'
```
### Common mistakes to avoid
- **NEVER** use raw `#fff`, `#000`, `#333`, `#666` etc. without wrapping in `var(--mui-palette-*)`
- **NEVER** use `rgba(0,0,0,0.5)` for overlays without a variable — this is the one exception where raw rgba is acceptable (backdrop overlays)
- **NEVER** assume white backgrounds or dark text — always use `background-paper`/`text-primary`
- For `<style>` blocks (drawers, etc.), use the same CSS variables in the stylesheet
- Fallback values after the comma are for environments where the variable isn't set — always use the light-mode default
### Form inputs in custom components
```typescript
const inputStyle = {
border: '1px solid var(--mui-palette-divider, #ccc)',
borderRadius: '4px',
backgroundColor: 'var(--mui-palette-background-paper)',
color: 'var(--mui-palette-text-primary)',
};
```
---
## Code Quality Rules
1. **Functional components only** — no class components (except ErrorBoundary)
2. **TypeScript strict mode** — no `any`; use `unknown` + type guards at API boundaries
3. **Headlamp CommonComponents + MUI**`@mui/material` is available via Headlamp's bundled deps; no other UI libraries (no Ant Design, etc.)
4. **Inline CSS only**`style={{}}` props, CSS variables (`var(--mui-palette-*)`) for theming
5. **Accessibility**`aria-label`, `aria-modal`, `role="dialog"`, `aria-live` for dynamic content
6. **Cancellation safety** — async effects must check a `cancelled` flag
7. **Error handling** — Result types in lib/, ErrorBoundaries wrapping components (ApiErrorBoundary for routes, GenericErrorBoundary for injected sections)
8. **Tests** — vitest + @testing-library/react, mock Headlamp APIs per above pattern
9. Run `npm run tsc` and `npm test` after implementation changes

### Fixed
- **ExemptionManager apiVersion bug**: `apps` and `batch` resources now correctly use `/apis/{group}/v1/` instead of the broken `/api/v1/` path
- **Strict TypeScript**: Replaced `resource: any` in InlineAuditSection with proper `KubeResource` interface
- **PolarisDataContext test mock**: Added missing `triggerRefresh` to mock, preventing silent `undefined` for `refresh` in context
- **DashboardView test**: Fixed `SimpleTable` mock that used `Array<any>` and didn't exercise column getters
### Changed
- **Dark mode / theming**: Replaced all `var(--mui-palette-*)` CSS variables with `useTheme()` + `theme.palette.*` across all components (DashboardView, NamespacesListView, InlineAuditSection, ExemptionManager, PolarisSettings, AppBarScoreBadge)
- **Namespace drawer**: Replaced custom `<style>` block + positioned `<div>` with MUI `Drawer` component for proper accessibility (`role="dialog"`, `aria-modal`, Escape key handling via MUI)
- **AppBarScoreBadge**: Uses `theme.palette.success/warning/error` with proper `contrastText` instead of hardcoded hex colors
- **ExemptionManager feedback**: Replaced `alert()` calls with `StatusLabel`-based inline feedback; removed dead `getExemptions()` stub and unreachable remove-exemption UI
- **URL construction**: Exported `getPolarisApiPath` and `isFullUrl` from `polaris.ts`; PolarisSettings now reuses them instead of duplicating logic
### Added
- **Error boundaries**: All registered components (routes, detail sections, app bar action) wrapped in `PolarisErrorBoundary` for graceful error rendering
- **Tests for InlineAuditSection** (7 tests): loading, unsupported kind, not found, score/summary, failing checks, link, exemption manager
- **Tests for AppBarScoreBadge** (6 tests): loading, no data, score colors, navigation, aria-label
- **Tests for topIssues.ts** (8 tests): empty, all pass, controller/pod/container results, counting, ignore filter, sorting, max 10
- **Tests for checkMapping.ts** (11 tests): name/description/category/severity lookups, unknown checks, CHECK_MAPPING structure validation
### Removed
- **NamespaceDetailView.tsx**: Dead code with no registered route (replaced by drawer in NamespacesListView)
- **NamespaceDetailView.test.tsx**: Tests for removed component
- **MockPolarisProvider in test-utils.tsx**: Unused mock provider (tests use `vi.mock` instead)
- **`getSeverityColor` export in checkMapping.ts**: Dead export not imported anywhere

# CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
## Project
Headlamp plugin surfacing Fairwinds Polaris audit results. Queries the Polaris dashboard API via Kubernetes service proxy (`/api/v1/namespaces/polaris/services/polaris-dashboard/proxy/results.json`). Read-only — no cluster write operations except exemption annotation patches.
- **Plugin name**: `polaris`
- **Target**: Headlamp >= v0.26
- **Data source**: Polaris dashboard service in `polaris` namespace
- **RBAC**: `get` on `services/proxy` resource `polaris-dashboard` in `polaris` namespace
## Commands
```bash
npm start # dev server with hot reload
npm run build # production build
npm run package # package for headlamp
npm run tsc # TypeScript type check (no emit)
npm run lint # ESLint
npm run lint:fix # ESLint with auto-fix
npm run format # Prettier write
npm run format:check # Prettier check
npm test # vitest run
npm run test:watch # vitest watch mode
npx vitest run src/api/polaris.test.ts # run a single test file
npm run e2e # Playwright E2E tests
npm run e2e:headed # Playwright headed mode
```
All tests and `tsc` must pass before committing.
## Architecture
```
src/
├── index.tsx # Plugin entry: registerRoute, registerSidebarEntry, registerDetailsViewSection, registerAppBarAction, registerPluginSettings; PolarisErrorBoundary
├── test-utils.tsx # Shared test fixtures (makeResult, makeAuditData)
├── api/
│ ├── polaris.ts # Types (AuditData schema), countResults utilities, refresh settings, getPolarisApiPath, isFullUrl
│ ├── checkMapping.ts # Polaris check ID → human-readable name mapping
│ ├── topIssues.ts # Top failing checks aggregation logic
│ └── PolarisDataContext.tsx # Shared React context provider (ApiProxy.request + configurable refresh)
└── components/
├── DashboardView.tsx # Overview page (score gauge, check distribution, top failing checks)
├── NamespacesListView.tsx # Namespace list with per-namespace scores + MUI Drawer detail panel
├── InlineAuditSection.tsx # Injected into Deployment/StatefulSet/DaemonSet/Job/CronJob detail views
├── ExemptionManager.tsx # Polaris exemption annotation management
├── AppBarScoreBadge.tsx # App bar cluster score chip
└── PolarisSettings.tsx # Plugin settings (refresh interval, dashboard URL)
```
## Data flow
Data is fetched via `ApiProxy.request` to the Polaris dashboard service proxy and refreshed on a user-configurable interval (stored in localStorage under `polaris-plugin-refresh-interval`, default 5 minutes). Score is computed from result counts (pass/total). `PolarisDataProvider` wraps each route component and detail-section registration in `index.tsx`.
**Sidebar limitation**: Headlamp's sidebar only supports 2-level nesting (parent → children). Namespace navigation is handled via the in-content table on the Namespaces page instead.
## Code conventions
- Functional React components only — class components only for error boundaries (PolarisErrorBoundary in index.tsx)
- All imports from `@kinvolk/headlamp-plugin/lib` and `@kinvolk/headlamp-plugin/lib/CommonComponents`
- `@mui/material` is available as a shared external via Headlamp — use `useTheme` from `@mui/material/styles` for theming, MUI `Drawer`/`IconButton` etc. as needed. Do NOT add `@mui/material` to package.json dependencies.
- Use `useTheme()` + `theme.palette.*` for all theme-aware colors — never use `var(--mui-palette-*)` CSS variables
- No other UI libraries (no Ant Design, etc.)
- TypeScript strict mode — no `any`, use `unknown` + type guards at API boundaries
- Context provider (`PolarisDataProvider`) wraps each route component in `index.tsx`
- All registered components wrapped in `PolarisErrorBoundary` for graceful error handling
- Tests: vitest + @testing-library/react, mock with `vi.mock('@kinvolk/headlamp-plugin/lib', ...)` and `vi.mock('@mui/material/styles', ...)`
- `vitest.setup.ts` provides a spec-compliant `localStorage` shim for Node 22+ compatibility
## Testing
Mock pattern for headlamp APIs:
```typescript
vi.mock('@kinvolk/headlamp-plugin/lib', () => ({
ApiProxy: { request: vi.fn().mockResolvedValue({}) },
K8s: { ResourceClasses: {} },
}));

# CONTEXT.md - Headlamp Polaris Plugin
**Purpose**: Comprehensive reverse prompt for AI assistants working on this project.
---
## Project Overview
The Headlamp Polaris Plugin surfaces [Fairwinds Polaris](https://www.fairwinds.com/polaris) audit results directly inside the [Headlamp](https://headlamp.dev) Kubernetes UI. It provides a read-only dashboard showing cluster-wide security, reliability, and efficiency scores derived from Polaris policy checks.
- **Stack**: React + TypeScript plugin for Headlamp (v0.26+)
- **Data Source**: Polaris dashboard API via Kubernetes service proxy (read-only)
- **Current Version**: v0.4.1
- **Key Constraint**: No direct Kubernetes resource access - all data fetched through service proxy
## Architecture & Data Flow
### Component Hierarchy
```
src/index.tsx # Entry point: registers routes, sidebar, settings
├── PolarisDataContext.tsx # Shared data fetch with auto-refresh
├── components/
│ ├── DashboardView.tsx # Overview (score, checks, top issues)
│ ├── NamespacesListView.tsx # Namespace list with scores
│ ├── NamespaceDetailView.tsx # Per-namespace drill-down (drawer)
│ ├── PolarisSettings.tsx # Settings (refresh interval, URL, test)
│ ├── AppBarScoreBadge.tsx # Cluster score badge in top nav
│ └── InlineAuditSection.tsx # Injected into workload detail views
└── api/
└── polaris.ts # Types, hooks, utilities
```
### Data Source
- **Service Proxy Path**: `/api/v1/namespaces/polaris/services/polaris-dashboard:80/proxy/results.json`
- **Schema**: `AuditData` with `ClusterInfo`, `Results[]` containing nested `PodResult` and `ContainerResults`
- **Method**: `ApiProxy.request()` from Headlamp plugin SDK (handles K8s API auth automatically)
### State Management
- **Pattern**: React Context (see `src/api/PolarisDataContext.tsx`)
- **Rationale**: ADR-001 - Prevents duplicate API calls when multiple components need same data
- **Auto-refresh**: User-configurable interval (1/5/10/30 min, default 5 min)
- **Storage**: Refresh interval and dashboard URL stored in `localStorage`
### Score Computation
```typescript
// Formula: (pass / total) * 100, rounded to nearest integer
function computeScore(counts: ResultCounts): number {
if (counts.total === 0) return 0;
return Math.round((counts.pass / counts.total) * 100);
}
```
## Technology Constraints
### ⚠️ CRITICAL: Headlamp Components Only
**MUST** use `@kinvolk/headlamp-plugin/lib/CommonComponents`
**NEVER** import from `@mui/material` or `@mui/icons-material`
**Why**: Historical issue (v0.3.2) - MUI imports caused plugin load failures. Headlamp provides all needed components as re-exports.
```typescript
// ✅ Correct
import { SectionBox, StatusLabel } from '@kinvolk/headlamp-plugin/lib/CommonComponents';
// ❌ Wrong - will break plugin
import { Box, Chip } from '@mui/material';
```
### Other Constraints
- **TypeScript Strictness**: No `any`, explicit types, strict mode enabled
- **Packaging**: `@kinvolk/headlamp-plugin` is peer dependency - don't bundle React/MUI
- **Theme Handling**: Use CSS variables (`--mui-palette-*`), not theme imports
- **Sidebar Limitation**: Headlamp only supports 2-level nesting (parent → children)
## Component Patterns & Gotchas
### Headlamp Component Issues
1. **StatusLabel with empty status**
```typescript
// ❌ Renders near-invisible (muted background)
<StatusLabel status="">{value}</StatusLabel>
// ✅ Use plain String() for neutral values
<span>{String(value)}</span>
```
2. **Link component crashes on plugin routes**
```typescript
// ❌ Headlamp Link crashes on plugin-registered routes
import { Link } from '@kinvolk/headlamp-plugin/lib/CommonComponents';
// ✅ Use react-router-dom Link with Router.createRouteURL
import { Link } from 'react-router-dom';
import { Router } from '@kinvolk/headlamp-plugin/lib';
<Link to={Router.createRouteURL('/polaris/namespaces')}>View</Link>
```
3. **Visual components that work well**
- `PercentageCircle` - Great for score display
- `PercentageBar` - Great for check distribution
- `SimpleTable` - Fast, clean tables
- `NameValueTable` - Key-value pairs
- `SectionBox` - Card containers with titles
### Code Conventions
- **Functional Components**: Always use function components with hooks
- **Named Exports**: Prefer named exports over default exports
- **Props Interfaces**: Define as TypeScript interfaces, not inline types
- **Import Order**: React → third-party → Headlamp → local (auto-sorted by eslint)
## RBAC & Security
### Minimal Permission Required
The plugin requires **only** this RBAC permission:
| Verb | API Group | Resource | Resource Name | Namespace |
|------|-----------|----------|---------------|-----------|
| `get` | `""` (core) | `services/proxy` | `polaris-dashboard` | `polaris` |
### Example Role
```yaml
apiVersion: rbac.authorization.k8s.io/v1
kind: Role
metadata:
name: polaris-proxy-reader
namespace: polaris
rules:
- apiGroups: [""]
resources: ["services/proxy"]
resourceNames: ["polaris-dashboard"]
verbs: ["get"]
---
apiVersion: rbac.authorization.k8s.io/v1
kind: RoleBinding
metadata:
name: headlamp-polaris-proxy
namespace: polaris
subjects:
- kind: ServiceAccount
name: headlamp
namespace: kube-system
roleRef:
kind: Role
name: polaris-proxy-reader
apiGroup: rbac.authorization.k8s.io
```
### Security Notes
- **Namespaced Role**: MUST be namespaced Role, NOT ClusterRole
- **ResourceNames Required**: Always specify `resourceNames: ["polaris-dashboard"]`
- **No Write Operations**: Plugin only performs GET, never create/update/delete
- **Token-Auth Mode**: When Headlamp uses user tokens, each user needs the RoleBinding
- **Network Policy**: If enforced, allow API server → `polaris-dashboard:80` ingress
- **Audit Logging**: Every proxy request logged as K8s API audit event
## Development Workflow
### Commands
```bash
# Install dependencies
npm install
# Start development mode (hot reload at localhost:4466)
npm start
# Build plugin
npm run build
# Create tarball for distribution
npm run package
# Type-check without emitting
npm run tsc
# Lint
npm run lint
# Run unit tests
npm test
# Run E2E tests (requires cluster access)
npm run e2e
# Format code
npm run format
# Check formatting (CI)
npm run format:check
```
### Branching Strategy
- ✅ **ALWAYS use feature branches** for code changes (`feat/*`, `fix/*`, `docs/*`)
- ✅ **MAY push directly to main** for: documentation-only changes, version bump commits
- ❌ **NEVER push code changes directly to main**
### Commit Convention
Use Conventional Commits:
- `feat:` - New feature
- `fix:` - Bug fix
- `docs:` - Documentation only
- `chore:` - Maintenance (deps, config)
- `test:` - Test changes
- `ci:` - CI/CD changes
### PR Process
All PRs must pass:
1. Build (`npm run build`)
2. Lint (`npm run lint`)
3. Type-check (`npm run tsc`)
4. Unit tests (`npm test`)
5. Format check (`npm run format:check`)
**Before committing**: Always run `npx prettier --write src/`
## Testing Strategy
### Unit Tests (Vitest)
```bash
npm test # Run once
npm run test:watch # Watch mode
```
- **Framework**: Vitest with jsdom environment
- **Test files**: `*.test.ts`, `*.test.tsx` in `src/`
- **Setup**: `vitest.setup.ts` with `@testing-library/jest-dom`
- **Coverage**: Focus on meaningful tests, not just numbers
- **Test utilities**: `src/test-utils.tsx` provides test wrapper with context
### E2E Tests (Playwright)
```bash
npm run e2e # Headless
npm run e2e:headed # With browser UI
```
- **Framework**: Playwright
- **Test files**: `e2e/*.spec.ts`
- `polaris.spec.ts` - Sidebar, overview, namespaces, detail drawer
- `settings.spec.ts` - Plugin settings page
- `appbar.spec.ts` - App bar score badge
- **Auth**: Supports both OIDC (Authentik) and token-based auth (see `e2e/auth.setup.ts`)
- **CI**: Runs on GitHub Actions with `k3s-animaniacs` runner
### Local E2E Setup
```bash
# Token-based auth
export HEADLAMP_TOKEN=$(kubectl create token headlamp -n kube-system --duration=24h)
npm run e2e
# OIDC auth (Authentik)
export AUTHENTIK_USERNAME=your-username
export AUTHENTIK_PASSWORD=your-password
npm run e2e
```
## CI/CD & Release
### CI Workflow (`.github/workflows/ci.yaml`)
Runs on push to main and all PRs:
1. Checkout
2. `npm ci`
3. `npm run build`
4. `npm run lint`
5. `npm run tsc`
6. `npm run format:check`
7. `npm test`
Runner: `local-ubuntu-latest`
### E2E Workflow (`.github/workflows/e2e.yaml`)
Runs on push, PR, and manual trigger:
1. Checkout
2. `npm ci`
3. `npm run e2e`
Runner: `k3s-animaniacs` (has cluster access)
Requires: `HEADLAMP_URL`, `HEADLAMP_TOKEN` or `AUTHENTIK_USERNAME`/`AUTHENTIK_PASSWORD`
### Release Workflow (`.github/workflows/release.yaml`)
**Manual trigger** via workflow_dispatch with version input:
```bash
# Via GitHub UI or CLI
gh workflow run release.yaml -f version=0.4.2
```
Steps:
1. Validate version format (semver)
2. Bump `package.json` + `artifacthub-pkg.yml`
3. Build plugin
4. Package tarball
5. Compute SHA256 checksum
6. Commit version bump
7. Create git tag
8. Create GitHub release
9. Upload tarball to release
**Guard**: Skips if checksum already matches (prevents infinite loop)
**Post-release**: ArtifactHub pulls metadata every 30 min (no webhook, pull-based)
### Version Bump Requirements
**ALWAYS bump both files in the same commit**:
- `package.json` - `version` field
- `artifacthub-pkg.yml` - `version` field + `digest` (checksum) + `archive.url`
## Known Issues & Workarounds
### ⚠️ Headlamp v0.39.0 Known Issues
**AutoSizer JavaScript Error**
- **Symptom**: Console shows `TypeError: undefined is not an object (evaluating 'io.AutoSizer')`
- **Impact**: Cosmetic error in Settings page, doesn't break functionality
- **Root Cause**: Headlamp core bug, not plugin-related
- **Workaround**: None needed, can be ignored
**Plugin Loading (RESOLVED)**
- **Old Issue**: Previously thought `config.watchPlugins: false` was required
- **Resolution**: Plugins load correctly with default `watchPlugins: true`
- **Note**: If you see old docs mentioning `watchPlugins: false`, ignore them
### Polaris Dashboard Behavior
**Stale Audit Data**
- **Symptom**: Plugin shows old audit timestamp
- **Root Cause**: Polaris dashboard runs audit once at pod startup, then caches results
- **Does NOT**: Continuously re-audit in real-time
- **Workaround**: Restart Polaris pods for fresh data
```bash
kubectl rollout restart deployment -n polaris polaris-dashboard
```
- **Load Balancing**: Service balances across multiple pods - each may have different audit timestamps
- **Plugin Auto-Refresh**: Works correctly - just fetches whatever Polaris currently has cached
### Skipped Count Limitation
**What It Shows**:
- Only checks with `Severity: "ignore"` in Polaris API response
- Does NOT include annotation-based exemptions (`polaris.fairwinds.com/*-exempt`)
**Why**:
- Polaris omits exempted checks from `results.json`
- Plugin has no access to raw K8s resources to compute exemptions
- By design: service proxy limitation
**Workaround**:
- Link to native Polaris dashboard for full exemption count
- UI tooltip explains this limitation
## Deployment Patterns
### Plugin Manager (Recommended)
Install via Headlamp UI (Settings → Plugins → Catalog) or Helm values:
```yaml
pluginsManager:
enabled: true
configContent: |
plugins:
- name: polaris
source: https://artifacthub.io/packages/headlamp/polaris/headlamp-polaris-plugin
```
### Sidecar Container (Alternative)
```yaml
spec:
containers:
- name: headlamp
# ... main container
- name: headlamp-plugin
image: node:lts-alpine
command:
- /bin/sh
- -c
- |
npx @headlamp-k8s/pluginctl@latest install \
--config /config/plugin.yml \
--folderName /headlamp/plugins \
--watch
volumeMounts:
- name: plugins-dir
mountPath: /headlamp/plugins
- name: plugin-config
mountPath: /config
volumes:
- name: plugins-dir
emptyDir: {}
- name: plugin-config
configMap:
name: headlamp-plugin-config
```
### Manual Tarball
```bash
# Download release
wget https://github.com/cpfarhood/headlamp-polaris-plugin/releases/download/v0.4.1/headlamp-polaris-plugin-0.4.1.tgz
# Extract to plugin directory
tar -xzf headlamp-polaris-plugin-0.4.1.tgz -C /headlamp/plugins/

## Anti-Patterns (What NOT to Do)
- ❌ Import from `@mui/material` or `@mui/icons-material` → breaks plugin
- ❌ Use `any` type → strict TypeScript required
- ❌ Push code changes directly to main → always use feature branches
- ❌ Grant broader RBAC than `get services/proxy` → security risk
- ❌ Use ClusterRole instead of namespaced Role → violates least privilege
- ❌ Forget to run `npx prettier --write src/` → CI will fail
- ❌ Use inline styles without CSS variables → breaks dark mode
- ❌ Try to query K8s resources directly → plugin only has service proxy access
- ❌ Import Headlamp `Link` for plugin routes → use react-router-dom `Link` + `Router.createRouteURL()`
- ❌ Assume Polaris continuously re-audits → it only audits at pod startup
## Quick Diagnosis Guide
```
Symptom: Plugin not in sidebar
→ Check: Hard refresh browser (Cmd+Shift+R / Ctrl+Shift+R)
→ Check: Plugin installed? kubectl get configmap headlamp-plugin-config -n kube-system
Symptom: 403 Access Denied
→ Check: RBAC binding exists? kubectl get role,rolebinding -n polaris
→ Fix: Apply RBAC example from docs/deployment/rbac.md
Symptom: 404 or 503
→ Check: Polaris installed? kubectl get pods -n polaris
→ Check: Service exists? kubectl get svc polaris-dashboard -n polaris
Symptom: Stale audit data
→ Fix: kubectl rollout restart deployment -n polaris polaris-dashboard
→ Verify: Check AuditTime in UI matches current date
Symptom: Settings page empty or broken
→ Check: Plugin version ≥ v0.3.3?
→ Fix: Upgrade plugin and hard refresh browser
Symptom: CI prettier check fails
→ Fix: npx prettier --write src/
→ Commit: Include formatting fixes in your PR
Symptom: Dark mode white backgrounds
→ Check: Plugin version ≥ v0.3.5?
→ Fix: Upgrade and hard refresh browser
```
## Historical Context
### Why Service Proxy Instead of ConfigMaps?
Early versions (< v0.0.10) incorrectly documented ConfigMap RBAC. The plugin **never** accessed ConfigMaps - it always used the service proxy. This was clarified in v0.0.10.
### Why No MUI Imports?
v0.3.2 removed direct MUI imports because they caused plugin load failures. Headlamp provides all needed MUI components as re-exports through `CommonComponents`.
### Why React Context?
ADR-001 documents the switch to React Context. Before v0.3.0, each component called `usePolarisData()` independently, causing duplicate API requests. Context ensures a single shared fetch.
### Why No Continuous Polaris Audits?
Polaris dashboard mode runs a one-time audit at pod startup and caches results. This is by design in Polaris itself. For continuous auditing, Polaris would need to be configured in webhook mode (admission controller), which is a different deployment pattern.

# CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
## Project Overview
Headlamp plugin that surfaces Fairwinds Polaris audit results inside the Headlamp UI. Queries the Polaris dashboard API via the Kubernetes service proxy (`/api/v1/namespaces/polaris/services/polaris-dashboard/proxy/results.json`). Target Headlamp ≥ v0.26.
## Build & Development Commands
```bash
# Install dependencies
npm install
# Build the plugin (standard Headlamp plugin build)
npx @kinvolk/headlamp-plugin build
# Start development mode with hot reload
npx @kinvolk/headlamp-plugin start
# Type-check without emitting
npx tsc --noEmit
# Lint
npx eslint src/
# Run tests
npm test
```

```
Top-level sidebar section at `/polaris` with sub-routes for namespaces list (`/polaris/namespaces`) and per-namespace views (`/polaris/ns/:namespace`). Data is fetched via `ApiProxy.request` to the Polaris dashboard service proxy and refreshed on a user-configurable interval (stored in localStorage under `polaris-plugin-refresh-interval`, default 5 minutes). Score is computed from result counts (pass/total). Skipped checks are always displayed in summaries.
**Sidebar limitation**: Headlamp's sidebar only supports 2-level nesting (parent → children). The `Collapse` component is driven by route-based selection, not click-to-toggle, so 3-level hierarchies don't expand properly. Namespace navigation is handled via the in-content table on the Namespaces page instead.
## Security / RBAC Requirements
The plugin reaches Polaris through the Kubernetes API server's service proxy sub-resource (`/api/v1/namespaces/polaris/services/polaris-dashboard/proxy/...`). The Headlamp service account (or the user's bearer token when Headlamp runs in token-auth mode) must be granted:
| Verb | API Group | Resource | Resource Name | Namespace |
|------|-----------|----------|---------------|-----------|
| `get` | `""` (core) | `services/proxy` | `polaris-dashboard` | `polaris` |
Minimal RBAC example:
```yaml
apiVersion: rbac.authorization.k8s.io/v1
kind: Role
metadata:
name: polaris-proxy-reader
namespace: polaris
rules:
- apiGroups: [""]
resources: ["services/proxy"]
resourceNames: ["polaris-dashboard"]
verbs: ["get"]
---
apiVersion: rbac.authorization.k8s.io/v1
kind: RoleBinding
metadata:
name: headlamp-polaris-proxy
namespace: polaris
subjects:
- kind: ServiceAccount
name: headlamp # adjust to match your Headlamp SA
namespace: kube-system
roleRef:
kind: Role
name: polaris-proxy-reader
apiGroup: rbac.authorization.k8s.io
```
Additional considerations:
- **NetworkPolicy**: If the `polaris` namespace enforces network policies, allow ingress from the Headlamp pod (or the API server, since it performs the proxy hop) to `polaris-dashboard` on port 80.
- **Polaris dashboard listen address**: The Polaris Helm chart exposes the dashboard on a ClusterIP service (`polaris-dashboard:80`). If the chart is installed with `dashboard.enabled: false`, the service will not be created, resulting in a 404 error for proxy requests.
- **No write operations**: The plugin only performs `GET` requests through the proxy. No `create`, `update`, or `delete` verbs are required. Do not grant broader service proxy access than `get`.
- **Token-auth mode**: When Headlamp is configured for user-supplied tokens (rather than a fixed service account), each user's own RBAC bindings must include the role above. A 403 from the plugin means the logged-in user lacks the binding.
- **Audit logging**: Kubernetes API audit logs will record every proxied request as a `get` on `services/proxy` in the `polaris` namespace. Set an appropriate audit policy level if request volume from the auto-refresh interval is a concern.
## Key Constraints
- **Data source**: Polaris dashboard API via K8s service proxy. Requires Polaris deployed in the `polaris` namespace with a `polaris-dashboard` service. No CRDs, no cluster write operations.
- **UI components**: Use only Headlamp-provided components (`@kinvolk/headlamp-plugin/lib/CommonComponents`). Do not import raw MUI packages. No custom theming.
- **Error handling**: Must handle 403 (RBAC denied), 404 (Polaris not installed), malformed JSON, and loading states with distinct visual states.
- **TypeScript strictness**: No `any`, no implicit `unknown` casting, no dead code, no unused imports.
- **Packaging**: `@kinvolk/headlamp-plugin` is a peer dependency. Do not bundle React or MUI.
## MCP Servers
The project has MCP server integrations configured in `.mcp.json`:
- **Gitea** (git.farh.net): Source control via `gitea-mcp-server`
- **Kubernetes** (local): Cluster access via `kubernetes-mcp-server`
- **Flux** (local): Flux Operator access via `flux-operator-mcp`

### Potential Improvements
1. **WebWorker for data processing**
- Offload `countResults()` aggregation for large clusters
- Keep UI responsive during heavy computation
2. **IndexedDB caching**
- Cache audit data offline
- Show stale data + "refresh available" indicator
3. **GraphQL/REST API abstraction**
- Decouple from Polaris dashboard JSON format
- Support multiple backend sources
4. **Plugin-to-plugin communication**
- Integrate with other Headlamp plugins (e.g., policy enforcement)
- Shared state between plugins

## Plugin Manager Setup
### Critical Configuration
**❌ WRONG (Will not load plugins):**
```yaml
config:
watchPlugins: true # Default, treats catalog plugins as dev plugins
```
**✅ CORRECT:**
```yaml
config:
watchPlugins: false # Required for plugin manager catalog plugins
```
### Why `watchPlugins: false` is Required
- **With `watchPlugins: true`:** Headlamp backend serves plugin metadata, but frontend never executes the JavaScript (treated as development directory plugin)
- **Result:** Plugins appear in Settings but no sidebar/routes/settings work
- **Fix:** Set `watchPlugins: false` in Headlamp configuration
- **Documentation:** See `deployment/PLUGIN_LOADING_FIX.md` for root cause analysis

## Plugin Not Showing in Sidebar
### Symptoms
- Plugin appears in Settings → Plugins but sidebar entry is missing
- No "Polaris" section in navigation
- Routes like `/polaris` return 404 or blank page
### Common Causes
**1. Headlamp v0.39.0+ Plugin Loading Issue**
**Root Cause**: Headlamp v0.39.0+ changed plugin loading behavior. With `config.watchPlugins: true` (default), catalog-managed plugins are treated as "development directory" plugins, causing the backend to serve metadata but frontend to never execute the JavaScript.
**Solution**: Set `config.watchPlugins: false` in Headlamp configuration.
```yaml
# HelmRelease values
config:
watchPlugins: false # CRITICAL for plugin manager
```
After applying this change:

2. Hard refresh browser (Cmd+Shift+R or Ctrl+Shift+R)

## Caching Strategy
**Current Implementation:**
- Data fetched once and stored in React Context
- Shared across all plugin views (no duplicate fetches)
- Cached until manual refresh or auto-refresh interval
**Cache Invalidation:**
- Manual refresh button click
- Auto-refresh interval elapses
- Settings change (dashboard URL)
**No Persistence:**
- Data NOT persisted to localStorage
- Each browser session fetches fresh data
- No offline mode
**Future Enhancement:**
- IndexedDB caching for offline access
- Incremental updates (fetch only changed namespaces)
- Service Worker for background refresh

## Known Issues
### Plugin Loading Issue (Headlamp v0.39.0+)
**Symptom:** Plugin appears in Settings but not in sidebar
**Cause:** `config.watchPlugins: true` (default) treats catalog plugins as development plugins
**Fix:**
```yaml
config:
watchPlugins: false # Required for plugin manager
```
**Root Cause:**
With `watchPlugins: true`, Headlamp backend serves plugin metadata but frontend never executes the JavaScript. This causes plugins to appear in Settings but no sidebar/routes/settings work.
**Documentation:** See `deployment/PLUGIN_LOADING_FIX.md` in repository for full analysis.
**After Fix:**
- Restart Headlamp deployment
- Hard refresh browser (**Cmd+Shift+R** / **Ctrl+Shift+R**)

#### Critical Configuration for Headlamp v0.39.0+
**⚠️ IMPORTANT:** You **must** set `config.watchPlugins: false` or the plugin will not load.
**Why?**
- With `watchPlugins: true` (default), catalog-managed plugins are treated as "development directory" plugins
- This causes the backend to serve metadata but the frontend never executes the JavaScript
- Result: Plugin appears in Settings but no sidebar/routes/settings work
**Fix:**

```yaml
rules:
- apiGroups: ["*"]
resources: ["*"]
verbs: ["*"]
- apiGroups: ['*']
resources: ['*']
verbs: ['*']
```
This grants cluster-admin equivalent permissions. Always use specific resources and verbs.
