## 🎮 Usage
|
||||
### Health Check Configuration
|
||||
|
||||
### Interactive Mode (Default)
|
||||
```yaml
|
||||
healthCheck:
|
||||
interval: "3s" # Check frequency
|
||||
timeout: "2s" # Check timeout
|
||||
method: "data-transfer" # tcp-dial or data-transfer
|
||||
maxConnectionAge: "25m" # Reconnect before k8s timeout
|
||||
maxIdleTime: "10m" # Detect idle connections
|
||||
|
||||
reliability:
|
||||
tcpKeepalive: "30s"
|
||||
dialTimeout: "30s"
|
||||
retryOnStale: true
|
||||
```
|
||||
|
||||
Health check methods:
|
||||
- `tcp-dial` - Fast TCP connection test
|
||||
- `data-transfer` - Verifies tunnel functionality by attempting data read
|
||||
|
||||
Connection age reconnection only triggers when the connection is also idle, preventing interruption of active transfers like database dumps.
|
||||
|
||||
### mDNS Hostnames
|
||||
|
||||
Enable mDNS to access forwards via `.local` hostnames:
|
||||
|
||||
```yaml
|
||||
mdns:
|
||||
enabled: true
|
||||
|
||||
contexts:
|
||||
- name: production
|
||||
namespaces:
|
||||
- name: default
|
||||
forwards:
|
||||
- resource: service/postgres
|
||||
port: 5432
|
||||
localPort: 5432
|
||||
alias: prod-db # Accessible via prod-db.local:5432
|
||||
```
|
||||
|
||||
- Explicit `alias` becomes `<alias>.local`
|
||||
- Without alias, hostname is generated from resource name (`service/redis` → `redis.local`)
|
||||
- Works on macOS (Bonjour) and Linux (avahi-daemon)
|
||||
|
||||
Verify registration:
|
||||
```bash
|
||||
dns-sd -B _kportal._tcp local # macOS
|
||||
avahi-browse -t _kportal._tcp # Linux
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
### Interactive Mode
|
||||
|
||||
```bash
|
||||
kportal
|
||||
```
|
||||
|
||||
Starts the interactive TUI where you can:
|
||||
- View all configured port-forwards in a table
|
||||
- See real-time status updates (Active, Starting, Reconnecting, Error)
|
||||
- Toggle forwards on/off with Space key
|
||||
- View detailed error messages at the bottom of the screen
|
||||
|
||||
### Verbose Mode
|
||||
|
||||
```bash
|
||||
kportal -v
|
||||
```
|
||||
|
||||
Runs in verbose mode with:
|
||||
- Detailed logging to stdout
|
||||
- Periodic status table updates every 2 seconds
|
||||
- Full error traces
|
||||
- No interactive controls (for automation/debugging)
|
||||
|
||||
### Validate Configuration
|
||||
|
||||
```bash
|
||||
kportal --check
|
||||
```
|
||||
|
||||
Validates your configuration file without starting any forwards:
|
||||
- Checks YAML syntax
|
||||
- Validates all required fields
|
||||
- Detects duplicate local ports
|
||||
- Shows validation errors with line numbers
|
||||
|
||||
### Custom Configuration File
|
||||
### Custom Config File
|
||||
|
||||
```bash
|
||||
kportal -c /path/to/config.yaml
|
||||
```
|
||||
|
||||
### Version Information
|
||||
## Status Indicators
|
||||
|
||||
| Indicator | Description |
|
||||
|-----------|-------------|
|
||||
| `● Active` | Connection healthy |
|
||||
| `○ Starting` | Initial connection (10s grace period) |
|
||||
| `◐ Reconnecting` | Reconnecting after failure |
|
||||
| `✗ Error` | Connection failed |
|
||||
| `○ Disabled` | Manually disabled |
|
||||
|
||||
## Advanced Features
|
||||
|
||||
### Hot-Reload
|
||||
|
||||
Configuration changes are applied automatically. Manual reload:
|
||||
|
||||
```bash
|
||||
kportal --version
|
||||
# Output: kportal version 0.1.5
|
||||
kill -HUP $(pgrep kportal)
|
||||
```
|
||||
|
||||
## 🔄 kftray Migration
|
||||
### Port Conflict Detection
|
||||
|
||||
Migrate from kftray JSON configuration:
|
||||
kportal validates port availability at startup and during hot-reload, showing which process is using conflicting ports.
|
||||
|
||||
### Retry Strategy
|
||||
|
||||
Exponential backoff: 1s → 2s → 4s → 8s → 10s (max). Retries continue indefinitely until connection succeeds.
|
||||
|
||||
## Migration from kftray
|
||||
|
||||
```bash
|
||||
kportal --convert configs.json --convert-output .kportal.yaml
|
||||
```
|
||||
|
||||
**Example conversion:**
|
||||
## Signal Handling

## 🛠️ Advanced Features
|
||||
|
||||
### Hot-Reload
|
||||
|
||||
kportal automatically watches for configuration file changes and reloads:
|
||||
|
||||
```bash
|
||||
# Edit your config while kportal is running
|
||||
vim .kportal.yaml
|
||||
|
||||
# Changes are applied automatically within seconds:
|
||||
# - New forwards are started
|
||||
# - Removed forwards are stopped
|
||||
# - Existing forwards continue running unchanged
|
||||
```
|
||||
|
||||
Supports manual reload via `SIGHUP`:
|
||||
```bash
|
||||
kill -HUP $(pgrep kportal)
|
||||
```
|
||||
|
||||
### Health Checks
|
||||
|
||||
Built-in health monitoring system:
|
||||
- **Check interval**: Every 5 seconds
|
||||
- **Timeout**: 2 seconds per check
|
||||
- **Grace period**: 10 seconds for new connections
|
||||
- **Automatic updates**: Real-time status changes in UI
|
||||
- **Error tracking**: Detailed error messages for failed connections
|
||||
|
||||
### Error Display
|
||||
|
||||
When connections fail, errors are displayed below the table:
|
||||
|
||||
```
|
||||
Errors:
|
||||
• prod-postgres: dial tcp 127.0.0.1:5432: connect: connection refused
|
||||
• prod-redis: i/o timeout after 2.0s
|
||||
```
|
||||
|
||||
Errors automatically clear when:
|
||||
- Connection becomes healthy
|
||||
- Forward is disabled
|
||||
- Forward is removed
|
||||
|
||||
### Port Conflict Detection
|
||||
|
||||
kportal checks for port conflicts at multiple stages:
|
||||
|
||||
**At startup:**
|
||||
```
|
||||
Port conflicts detected:
|
||||
Port 8080:
|
||||
• Requested by: api-server (context: prod, namespace: default)
|
||||
• Currently used by: PID 1234 (chrome)
|
||||
```
|
||||
|
||||
**During hot-reload:**
|
||||
- Only validates new ports being added
|
||||
- Skips currently managed ports
|
||||
- Rejects configuration if conflicts found
|
||||
|
||||
### Pod Restart Handling
|
||||
|
||||
When a pod restarts:
|
||||
1. Port-forward connection breaks
|
||||
2. kportal immediately re-resolves the resource:
|
||||
- For prefix matches: Finds newest pod with matching prefix
|
||||
- For selectors: Re-queries pods with matching labels
|
||||
3. Reconnects to new pod
|
||||
4. Logs the switch: `Switched to new pod: old-pod-abc → new-pod-xyz`
|
||||
|
||||
### Retry Strategy
|
||||
|
||||
Exponential backoff with maximum interval:
|
||||
- **Intervals**: 1s → 2s → 4s → 8s → 10s (max)
|
||||
- **Infinite retries**: Continues until connection succeeds
|
||||
- **Independent**: Each forward has its own retry logic
|
||||
- **Grace period**: First 10 seconds show "Starting" instead of "Error"
|
||||
|
||||

|
||||
|
||||
## 🐛 Troubleshooting
|
||||
|
||||
### Port Already in Use
|
||||
|
||||
**Problem**: `Port 8080: already in use by PID 1234 (chrome)`
|
||||
|
||||
**Solutions**:
|
||||
```bash
|
||||
# Find the process
|
||||
lsof -i :8080
|
||||
|
||||
# Kill the process
|
||||
kill 1234
|
||||
|
||||
# Or use a different local port in config
|
||||
local_port: 8081
|
||||
lsof -i :<port>
|
||||
kill <pid>
|
||||
```
|
||||
|
||||
### Connection Refused
|
||||
|
||||
**Problem**: `dial tcp 127.0.0.1:8080: connect: connection refused`
|
||||
|
||||
**Common causes**:
|
||||
1. **Pod not ready yet** - Wait for status to change from "Starting" → "Active" (10s grace period)
|
||||
2. **Wrong port number** - Verify the pod/service actually exposes that port
|
||||
3. **Service not exposed** - Check with `kubectl get svc` and `kubectl describe svc <name>`
|
||||
|
||||
**Debug**:
|
||||
```bash
|
||||
# Check pod status
|
||||
kubectl get pods -n <namespace>
|
||||
|
||||
# Check if port is exposed
|
||||
kubectl describe pod <pod-name> -n <namespace>
|
||||
|
||||
# Check service endpoints
|
||||
kubectl get endpoints <service-name> -n <namespace>
|
||||
```
|
||||
1. Verify pod is running: `kubectl get pods -n <namespace>`
|
||||
2. Verify port is correct: `kubectl describe pod <pod>`
|
||||
3. Check service endpoints: `kubectl get endpoints <service>`
|
||||
|
||||
### Context Not Found
|
||||
|
||||
**Problem**: `context "prod" not found in kubeconfig`
|
||||
|
||||
**Solution**:
|
||||
```bash
|
||||
# List available contexts
|
||||
kubectl config get-contexts
|
||||
|
||||
# Verify context name matches
|
||||
kubectl config current-context
|
||||
|
||||
# Update your config to use the correct context name
|
||||
```
|
||||
|
||||
### Health Check Errors During Startup
|
||||
## 🔧 Development
|
||||
|
||||
**Problem**: Seeing "Error" status immediately after starting
|
||||
### Prerequisites
|
||||
|
||||
**This is normal!** kportal has a 10-second grace period. If the connection is still failing after 10 seconds, check:
|
||||
- Pod is running: `kubectl get pods`
|
||||
- Port is correct in config
|
||||
- Network connectivity to cluster
|
||||
- Go 1.23+
|
||||
- Kubernetes cluster access
|
||||
- kubectl configured
|
||||
|
||||
### Logs Covering UI
|
||||
### Build
|
||||
|
||||
**Problem**: Kubernetes client logs appearing over the interactive UI
|
||||
|
||||
**This is fixed in v0.1.5+**. The interactive mode now completely suppresses all logs including:
|
||||
- Standard Go `log` package
|
||||
- Kubernetes `klog` output
|
||||
- Any stderr/stdout leakage
|
||||
|
||||
If you still see logs, please file an issue!

## 🚀 Release Workflow
|
||||
|
||||
### Standard Release Process
|
||||
|
||||
1. **Develop features**
|
||||
1. **Make changes and test**
|
||||
```bash
|
||||
git checkout -b feature/my-feature
|
||||
# Make changes
|
||||
make test
|
||||
make all
|
||||
make test && make all
|
||||
```
|
||||
|
||||
2. **Commit with semantic messages**
|
||||
```bash
|
||||
git commit -m "feat: add amazing feature"
|
||||
git commit -m "fix: resolve bug in health check"
|
||||
```
|
||||
2. **Update CHANGELOG.md**
|
||||
|
||||
3. **Update CHANGELOG.md**
|
||||
```markdown
|
||||
## [0.2.0] - 2025-11-24
|
||||
|
||||
### Added

|
||||
3. **Tag and push**
|
||||
```bash
|
||||
git tag -a v0.2.0 -m "Release v0.2.0"
|
||||
git push origin main
|
||||
git push origin v0.2.0
|
||||
```
|
||||
|
||||
5. **CI/CD automatically**:
|
||||
- Builds all binaries
|
||||
- Creates GitHub release
|
||||
- Updates Homebrew formula
|
||||
- Attaches binaries and checksums
|
||||
## Version Bumping
|
||||
|
||||
### Version Bumping (Semantic Versioning)
|
||||
Version determined by commit message keywords:
|
||||
|
||||
Version is automatically determined by semver-gen from commit messages:
|
||||
| Bump | Keywords |
|
||||
|------|----------|
|
||||
| Patch (0.0.X) | `fix`, `bugfix`, `docs`, `test`, `refactor` |
|
||||
| Minor (0.X.0) | `feat`, `feature`, `add`, `enhance`, `update` |
|
||||
| Major (X.0.0) | `breaking`, `major`, `BREAKING CHANGE` |
|
||||
|
||||
- **Patch** (0.0.X): `fix`, `bugfix`, `hotfix`, `patch`, `docs`, `test`, `refactor`

||||
git push origin v0.1.5
|
||||
```
|
||||
|
||||
### 5. Test Installation Methods
|
||||
|
||||
After first release, test:
|
||||
```bash
|
||||
# Homebrew (once tap is set up)
|
||||
brew install lukaszraczylo/tap/kportal
|
||||
|
||||
# Quick install script
|
||||
curl -fsSL https://raw.githubusercontent.com/lukaszraczylo/kportal/main/install.sh | bash
|
||||
|
||||
# Manual download
|
||||
# Visit releases page and download binary
|
||||
```
|
||||
|
||||
## 🎨 Customization
|
||||
|
||||
### Update Website Colors
|
||||
|
||||
Edit `docs/index.html`:
|
||||
```javascript
|
||||
tailwind.config = {
|
||||
theme: {
|
||||
extend: {
|
||||
colors: {
|
||||
primary: '#3b82f6', // Blue
|
||||
secondary: '#8b5cf6', // Purple
|
||||
dark: '#0f172a', // Dark slate
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Update Release Notes Template
|
||||
|
||||
Edit `.github/workflows/release.yml` in the "Generate release notes" step.
|
||||
|
||||
## 📊 Monitoring
|
||||
|
||||
After releases, monitor:
|
||||
- GitHub Actions workflow runs
|
||||
- GitHub Releases page
|
||||
- Homebrew tap repository commits
|
||||
- Download statistics on releases page
|
||||
- Value: Personal access token with `repo` scope
|
||||
|
||||
## 🐛 Troubleshooting
|
||||
|
||||
### Release workflow fails
|
||||
- Check GitHub Actions logs
|
||||
- Verify all required secrets are set
|
||||
- Ensure tag follows v\d+.\d+.\d+ format
|
||||
- Verify secrets are configured
|
||||
- Ensure tag follows `v\d+.\d+.\d+` format
|
||||
|
||||
### Homebrew formula not updating
|
||||
- Verify HOMEBREW_TAP_TOKEN is valid
|
||||
### Homebrew not updating
|
||||
- Verify `HOMEBREW_TAP_TOKEN` is valid
|
||||
- Check tap repository permissions
|
||||
- Review release workflow logs
|
||||
|
||||
### Install script fails
|
||||
- Test locally with different OS/arch combinations
|
||||
- Check release binary naming matches script expectations
|
||||
- Verify binaries are attached to release
|
||||
|
||||

# Interactive Wizards
|
||||
|
||||
kportal includes wizards for adding and removing port forwards from the running UI.
|
||||
|
||||
## ⌨️ Quick Reference
|
||||
|
||||
| Key | Action |
|
||||
|-----|--------|
|
||||
| `a` | Add new forward |
|
||||
| `d` | Delete forwards |
|
||||
|
||||
## ➕ Add Forward Wizard
|
||||
|
||||
Press `a` from the main view to start the wizard.
|
||||
|
||||
### Steps
|
||||
|
||||
1. **Context** - Select Kubernetes context
|
||||
2. **Namespace** - Select namespace
|
||||
3. **Resource Type** - Choose pod (prefix), pod (selector), or service
|
||||
4. **Resource** - Enter prefix, selector, or select service
|
||||
5. **Remote Port** - Enter port on the resource
|
||||
6. **Local Port** - Enter local port (validates availability)
|
||||
7. **Confirm** - Review and optionally add an alias
|
||||
|
||||
### Navigation
|
||||
|
||||
| Key | Action |
|
||||
|-----|--------|
|
||||
| `↑↓` / `j/k` | Navigate options |
|
||||
| `Enter` | Confirm and proceed |
|
||||
| `Esc` | Go back / Cancel |
|
||||
| `Ctrl+C` | Cancel immediately |
|
||||
|
||||
## 🗑️ Delete Forward Wizard
|
||||
|
||||
Press `d` from the main view.
|
||||
|
||||
### Navigation
|
||||
|
||||
| Key | Action |
|
||||
|-----|--------|
|
||||
| `↑↓` / `j/k` | Navigate |
|
||||
| `Space` | Toggle selection |
|
||||
| `a` | Select all |
|
||||
| `n` | Deselect all |
|
||||
| `Enter` | Confirm deletion |
|
||||
| `Esc` | Cancel |
|
||||
|
||||
## 🎯 Resource Selection
|
||||
|
||||
### Pod by Prefix
|
||||
|
||||
Enter app name prefix to match pods:
|
||||
- `nginx` matches `nginx-deployment-abc123`
|
||||
- `postgres` matches `postgres-statefulset-0`
|
||||
|
||||
### Pod by Selector
|
||||
|
||||
Use Kubernetes label syntax:
|
||||
- `app=nginx`
|
||||
- `app=nginx,env=prod`
|
||||
|
||||
Matching pods are shown in real-time.
|
||||
|
||||
### Service
|
||||
|
||||
Select from discovered services in the namespace.
|
||||
|
||||
## 🔄 Auto Hot-Reload
|
||||
|
||||
Changes are applied automatically:
|
||||
1. Wizard writes to `.kportal.yaml` atomically
|
||||
2. File watcher detects change (~100ms)
|
||||
3. Manager reloads and starts forward
|
||||
4. UI updates
|
||||
|
||||
## Error Handling
|
||||
|
||||
The wizards handle:
|
||||
- Cluster unreachable - allows manual entry
|
||||
- Port conflicts - shows which process is using the port
|
||||
- Invalid selectors - real-time validation
|
||||
- Duplicate ports - prevents conflicts
|
||||
|
||||
## 🐛 Troubleshooting
|
||||
|
||||
### Wizard not appearing
|
||||
|
||||
Verify cluster connectivity:
|
||||
```bash
|
||||
kubectl cluster-info
|
||||
```
|
||||
|
||||
### Port validation delayed
|
||||
|
||||
Port checks run asynchronously. Wait briefly after typing.
|
||||
|
||||
### Changes not visible
|
||||
|
||||
Check:
|
||||
1. `.kportal.yaml` was written correctly
|
||||
2. No validation errors in file
|
||||
3. kportal process is running
