# kpf - A better way to port-forward with kubectl
This is a Python utility that (attempts) to dramatically improve the experience of port-forwarding with kubectl.
Primary features:
Interactive service selection with colored tables and support for multiple Kubernetes resource types.
Automatically restarts port-forwards when endpoint changes are detected. Normally (without this tool), this is a terrible experience with the port-forward cli only updating after you switch to a browser and attempt to connect.
## Features
- 🔄 **Automatic Restart**: Monitors endpoint changes and restarts port-forward automatically
- 🎯 **Interactive Selection**: Choose services with a colorful, intuitive interface
- 🌈 **Color-coded Status**: Green for services with endpoints, red for those without
- 🔍 **Multi-resource Support**: Services, pods, deployments, and more
- 📊 **Rich Tables**: Beautiful formatted output with port information
- 🏷️ **Namespace Aware**: Work with specific namespaces or across all namespaces
## Installation
**Note**: `oh-my-zsh` kubectl plugin will conflict with this `kpf` command. If you prefer this tool, you can alias at the bottom of your `~/.zshrc` file or use a different alias.
If you have `uv` installed, you can "install" `kpf` with:
```bash
alias kpf="uvx kpf"
```
Install uv with pipx:
```bash
pipx install uv
```
## Usage
### Interactive Mode (Recommended)
**Warm Tip**: You can use the interactive mode to find the service you want, and the command to connect to that service directly next time is output just before the connection is established.
Select services interactively with a colored table:
```bash
# Interactive selection in current namespace
kpf --prompt
# or just:
kpf -p
# Interactive selection in specific namespace
kpf --prompt -n production
# or just:
kpf -p -n production
# Show all services across all namespaces
kpf --all
# Include pods and deployments with ports defined
kpf --all-ports
```
### Check Mode
Add endpoint status checking to service selection (slower but shows endpoint health):
```bash
# Interactive selection with endpoint status
kpf --prompt --check
# Show all services with endpoint status
kpf --all --check
# Include pods and deployments with status
kpf --all-ports --check
```
### Legacy Mode
Direct port-forward (backward compatible):
```bash
# Traditional kubectl port-forward syntax
kpf svc/frontend 8080:8080 -n production
kpf pod/my-pod 3000:3000
```
### Command Options
```sh
There is no default command. You must specify one of the arguments below.
You could alias kpf to -p to use interactive mode by default if you prefer.
Example of this in your ~/.zshrc:
alias kpf='uvx kpf -p'
Example usage:
kpf svc/frontend 8080:8080 -n production # Direct port-forward (backwards compatible with kpf alias)
kpf --prompt (or -p) # Interactive service selection
kpf --prompt -n production # Interactive selection in specific namespace
kpf --all (or -A) # Show all services across all namespaces
kpf --all-ports (or -l) # Show all services with their ports
kpf --prompt --check -n production # Interactive selection with endpoint status
```
## Examples
### Interactive Service Selection
Fast mode (without endpoint checking):
```bash
$ kpf --prompt -n kube-system
Services in namespace: kube-system
# Type Name Ports
1 SERVICE kube-dns 53, 9153
2 SERVICE metrics-server 443
3 SERVICE kubernetes-dashboard 443
Select a service [1]: 1
Local port (press Enter for 53): 5353
```
With endpoint status checking:
```bash
$ kpf --prompt --check -n kube-system
Services in namespace: kube-system
# Type Name Ports Status
1 SERVICE kube-dns 53, 9153 ✓
2 SERVICE metrics-server 443 ✓
3 SERVICE kubernetes-dashboard 443 ✗
✓ = Has endpoints ✗ = No endpoints
Select a service [1]: 1
Local port (press Enter for 53): 5353
```
### Cross-Namespace Discovery
```bash
$ kpf --all
Services across all namespaces
# Namespace Type Name Ports Status
1 default SERVICE kubernetes 443 ✓
2 kube-system SERVICE kube-dns 53, 9153 ✓
3 production SERVICE frontend 80, 443 ✓
4 production SERVICE backend 8080 ✗
```
## How It Works
1. **Port-Forward Thread**: Runs kubectl port-forward in a separate thread
2. **Endpoint Watcher**: Monitors endpoint changes using `kubectl get ep -w`
3. **Automatic Restart**: When endpoints change, gracefully restarts the port-forward
4. **Service Discovery**: Uses kubectl to discover services and their endpoint status
## Requirements
- Python 3.8+
- kubectl configured with cluster access
- Rich library for colored output
## Development
### Setup Development Environment
```bash
# Clone the repository
git clone https://github.com/jessegoodier/kpf.git
cd kpf
# Install with development dependencies
uv venv
uv pip install -e ".[dev]"
source .venv/bin/activate
```
### Code Quality Tools
```bash
# Format and lint code
uvx ruff check . --fix
uvx ruff format .
# Sort imports
uvx isort .
# Run tests
uv run pytest
# Bump version
uvx bump-my-version bump patch --allow-dirty --no-commit --no-tag
```
