# TASK: Create CLAUDE.md + cleanup + statusIcon fix (felhom.eu repo)

## Context

The `felhom.eu` repo lacks a CLAUDE.md with build instructions for the hub, has no `.gitignore` (so `hub.exe` got committed), and has a statusIcon rendering bug on the hub dashboard.

**Current state:** Hub v0.1.2 running on k3s. Controller v0.6.2 on demo node.

All changes in this task are in the **felhom.eu repo** only.

---

## Task 1: Create CLAUDE.md

Create `CLAUDE.md` in the repo root (`E:\git\felhom.eu\CLAUDE.md`) with the following content.
Use the controller's `CLAUDE.md` (in `deploy-felhom-compose`) as a style reference.

The CLAUDE.md should include these sections:

### Project overview

This repo (`felhom.eu`) contains:
- **Website** (`website/`) — Static HTML pages at felhom.eu, served via k3s nginx + git-sync sidecar
- **Hub** (`hub/`) — Go application (felhom-hub) — centralized dashboard for monitoring customer controllers, runs on k3s at hub.felhom.eu
- **K8s manifests** (`manifests/`) — k3s deployment manifests for all felhom-system services

See `README.md` for full architecture, DNS, email, and SEO documentation.
See `TASK.md` for the current task to implement (if it exists).

### Code quality rules

Same as controller CLAUDE.md:
- Always double-check generated code for bugs, logic issues, syntax errors
- Handle edge cases without overcomplicating
- Add debug capabilities for troubleshooting
- Ask for more input rather than guessing

### SSH access

SSH key-based authentication configured. No password prompts.

| Host | IP | User | Role |
|------|----|------|------|
| Build server (k3s node) | 192.168.0.180 | kisfenyo | Build + push images, kubectl |
| Demo node | 192.168.0.162 | kisfenyo | Test deployment (demo-felhom.eu) |

**Note:** `kubectl` on the build server requires `sudo` (k3s kubeconfig permissions).

### Build & deploy workflow — Hub

After making code changes to `hub/`, you **MUST** build, push, and deploy the new image.
Do NOT leave code changes uncommitted or undeployed.

#### Step 1: Commit and push changes

```bash
cd /e/git/felhom.eu
git add -A && git commit -m "<descriptive message>" && git push
```

#### Step 2: Build + push the container image on the build server

The build server (192.168.0.180) has the build toolchain. The build script lives at
`~/build/felhom-hub/build.sh` on the build server (NOT in this repo).

First, check the current running version:
```bash
ssh kisfenyo@192.168.0.180 "sudo kubectl get deploy -n felhom-system hub -o jsonpath='{.spec.template.spec.containers[0].image}'"
```

Then build with the next version (e.g., if current is 0.1.2, use 0.1.3):
```bash
ssh kisfenyo@192.168.0.180 "cd ~/build/felhom-hub && ./build.sh <NEW_VERSION> --push"
```

The build script:
- Pulls latest code from Gitea (`git pull` on the felhom.eu repo)
- Copies `hub/` source to a clean build workspace
- Builds Docker image with version + build-time ldflags
- Pushes to `gitea.dooplex.hu/admin/felhom-hub:<VERSION>` and `:latest`

#### Step 3: Deploy to k3s

```bash
ssh kisfenyo@192.168.0.180 "sudo kubectl set image -n felhom-system deploy/hub hub=gitea.dooplex.hu/admin/felhom-hub:<NEW_VERSION>"
```

#### Step 4: Verify the deployment

```bash
ssh kisfenyo@192.168.0.180 "sudo kubectl get pods -n felhom-system -l app=hub && echo '---' && sudo kubectl logs -n felhom-system -l app=hub --tail 10"
```

Should show pod Running and `[INFO] felhom-hub <VERSION> starting` in logs.

#### Build workflow summary

| Step | Command | Where |
|------|---------|-------|
| 1. Commit + push | `git add -A && git commit && git push` | Local (this repo) |
| 2. Build + push image | `ssh 192.168.0.180 "cd ~/build/felhom-hub && ./build.sh <VER> --push"` | Build server |
| 3. Deploy | `ssh 192.168.0.180 "sudo kubectl set image -n felhom-system deploy/hub hub=...:<VER>"` | Build server (kubectl) |
| 4. Verify | `ssh 192.168.0.180 "sudo kubectl get pods -n felhom-system -l app=hub"` | Build server |

### Build & deploy workflow — Website

The website auto-deploys via git-sync sidecar. Just push to `main`:

```bash
cd /e/git/felhom.eu
git add -A && git commit -m "<message>" && git push
```

Changes are live within 1-2 minutes. No build step needed.

For emergency edits, use FileBrowser at `https://files.felhom.eu`.

### Build & deploy workflow — K8s Manifests

Manifests are applied manually:

```bash
ssh kisfenyo@192.168.0.180 "sudo kubectl apply -f /home/kisfenyo/git/felhom.eu/manifests/<manifest>.yaml"
```

Remember to `git pull` on the build server first if you pushed changes locally.

### Tech stack (Hub)

- **Language:** Go 1.24+
- **Web framework:** stdlib `net/http` + `html/template`
- **Database:** SQLite via `modernc.org/sqlite` (pure Go, no CGo)
- **Auth:** bcrypt password hash + basic auth
- **Deployment:** Docker container on k3s (felhom-system namespace)
- **Storage:** Longhorn PVC at `/data/` (SQLite DB)
- **Config:** YAML file mounted via k8s ConfigMap at `/etc/felhom-hub/hub.yaml`

### Key patterns

- Hub receives reports from customer controllers via `POST /api/v1/report` (Bearer token auth)
- Dashboard shows all customers in a table with status, CPU, memory, disk, containers, backup age
- Customer detail page shows system info, report history, full JSON report
- Status logic: OK (report < 30m), WARN (30m-1h or health=warn), DOWN (> 1h or health=fail)
- SQLite timestamps may vary in format — use `parseSQLiteTime()` for robust parsing
- Auto-refresh: dashboard and detail pages refresh every 60 seconds via `<meta http-equiv="refresh">`
- Geo-restricted to Hungary via nginx ingress annotation

### File encoding

All HTML files in `website/` are **UTF-8 with BOM**. Ensure your editor preserves this.
Hub Go source files are standard UTF-8 (no BOM).

## Task 2: Create .gitignore

Create `.gitignore` in the repo root with appropriate entries:

```gitignore
# Go binaries
hub/hub
hub/hub.exe
hub/bin/

# Build artifacts
*.exe
*.dll
*.so
*.dylib

# Test and coverage
*.test
*.out
coverage.html

# IDE
.idea/
.vscode/
*.swp
*.swo
*~

# OS
.DS_Store
Thumbs.db

# Temporary files
*.tmp
*.bak
```

## Task 3: Remove hub.exe from git history

After creating `.gitignore`, remove the committed binary:

```bash
git rm --cached hub/hub.exe
```

This removes it from tracking but the `.gitignore` prevents re-adding. No need to rewrite
history — just remove from current tree.

Also check for any other binaries that shouldn't be tracked:
```bash
find hub/ -name "*.exe" -o -name "hub" -type f -executable
```

## Task 4: Fix hub statusIcon rendering

**File:** `hub/internal/web/server.go`

**Problem:** `statusIcon()` returns HTML entities (`&#x1F7E2;`), but Go's `html/template`
auto-escapes them to literal text (`&amp;#x1F7E2;`). Additionally, emoji don't respond to
CSS `color` — but the templates already apply `style="color: {{statusColor .OverallStatus}}"`.

**Fix:** Change `statusIcon()` to return `●` (U+25CF, BLACK CIRCLE) — a plain Unicode character
that responds to CSS color styling. The existing `statusColor()` function handles color differentiation.

```go
// BEFORE (broken):
func statusIcon(status string) string {
	switch status {
	case "ok":
		return "&#x1F7E2;" // green circle
	case "warn":
		return "&#x1F7E1;" // yellow circle
	case "down", "fail":
		return "&#x1F534;" // red circle
	default:
		return "&#x26AA;" // white circle
	}
}

// AFTER (works with CSS color):
func statusIcon(status string) string {
	return "●"
}
```

No template changes needed — `statusColor()` already provides the correct color per status.

**Verification:**
1. Dashboard: colored dot (green/yellow/red) before customer name, no `&#x` text
2. Customer detail: colored dot in header
3. Colors match status (green=OK, yellow=WARN, red=DOWN)

---

## Build & Deploy

After all changes, commit and deploy hub v0.1.3:

```bash
# 1. Commit
cd /e/git/felhom.eu
git add -A && git commit -m "add CLAUDE.md, .gitignore, fix statusIcon rendering" && git push

# 2. Build
ssh kisfenyo@192.168.0.180 "cd ~/build/felhom-hub && ./build.sh 0.1.3 --push"

# 3. Deploy
ssh kisfenyo@192.168.0.180 "sudo kubectl set image -n felhom-system deploy/hub hub=gitea.dooplex.hu/admin/felhom-hub:0.1.3"

# 4. Verify
ssh kisfenyo@192.168.0.180 "sudo kubectl rollout status -n felhom-system deploy/hub && sudo kubectl logs -n felhom-system -l app=hub --tail 5"
```

## Post-deploy checklist

- [ ] `hub.felhom.eu` shows colored `●` dot, not `&#x1F7E2;` text
- [ ] `hub.exe` no longer in repo (`git ls-files hub/hub.exe` returns empty)
- [ ] `CLAUDE.md` exists in repo root
- [ ] `.gitignore` exists in repo root
