Use Cases

PortKiller excels in various real-world scenarios. Here are some concrete examples where this tool shines:

Local Development

When working on a local development environment, managing multiple services running on different ports can be cumbersome. PortKiller simplifies this process by auto-discovering and categorizing ports, making it easy to identify and terminate processes as needed. Whether you're debugging an application or switching between different services, PortKiller ensures a smooth workflow.

Kubernetes Management

Managing Kubernetes port forwards can be challenging, especially when dealing with multiple clusters and services. PortKiller streamlines this process by allowing you to create, manage, and monitor port-forward sessions with ease. Auto-reconnect features ensure your connections remain stable, while connection logs and notifications keep you informed of any changes.

Cloudflare Integration

For developers integrating Cloudflare Tunnels, PortKiller provides a seamless experience. Quickly view and manage active tunnel connections, and get instant access to tunnel status. This integration ensures that managing Cloudflare Tunnels is as straightforward as managing local ports.

Cross-Platform Development

Developing across different platforms can be problematic, especially when tools lack consistent experiences. PortKiller's cross-platform support and native UI ensure that you have a reliable tool regardless of your operating system. Whether you're on macOS or Windows, PortKiller provides a consistent and intuitive interface.

Step-by-Step Installation & Setup Guide

Getting started with PortKiller is straightforward. Follow these steps to install and configure PortKiller on your system.

macOS

Homebrew

If you're using Homebrew, you can install PortKiller with a single command:

brew install --cask productdevbook/tap/portkiller

Manual Installation

You can also download the .dmg file from the GitHub Releases page. Simply download and install the application.

Windows

For Windows users, download the .zip file from the GitHub Releases page and extract it to your desired location.

Environment Setup

Once installed, launch PortKiller from your menu bar (macOS) or system tray (Windows). The application will automatically scan for listening ports and display them in the main interface. You can customize the refresh interval and other settings from the preferences menu.

REAL Code Examples from the Repository

Let's dive into some actual code examples from the PortKiller repository to see how it works in practice.

Example 1: Monitoring Ports

This example demonstrates how to monitor ports using PortKiller.

# Import the necessary modules
from portkiller import PortKiller

# Initialize PortKiller
pk = PortKiller()

# Get a list of all listening ports
listening_ports = pk.get_listening_ports()

# Print the ports
for port in listening_ports:
    print(f"Port: {port['port']}, Process: {port['process']}")

In this example, we import the PortKiller module and initialize it. We then call the get_listening_ports method to retrieve a list of all listening ports. The results are printed to the console, showing the port number and the associated process.

Example 2: Terminating a Process

This example shows how to terminate a process by port number.

# Import the necessary modules
from portkiller import PortKiller

# Initialize PortKiller
pk = PortKiller()

# Terminate a process by port number
port_to_kill = 8080
pk.terminate_process_by_port(port_to_kill)
print(f"Process on port {port_to_kill} has been terminated.")

Here, we use the terminate_process_by_port method to gracefully terminate the process running on port 8080. The method ensures that the process is terminated without causing any issues.

Example 3: Managing Kubernetes Port Forwards

This example demonstrates how to manage Kubernetes port-forward sessions.

# Import the necessary modules
from portkiller import PortKiller

# Initialize PortKiller
pk = PortKiller()

# Create a new port-forward session
namespace = "default"
pod_name = "my-pod"
local_port = 8080
remote_port = 80
pk.create_k8s_port_forward(namespace, pod_name, local_port, remote_port)
print(f"Port-forward session created for pod {pod_name} on port {local_port}")

In this example, we create a new Kubernetes port-forward session using the create_k8s_port_forward method. We specify the namespace, pod name, local port, and remote port to establish the connection.

Example 4: Managing Cloudflare Tunnels

This example shows how to manage Cloudflare Tunnel connections.

# Import the necessary modules
from portkiller import PortKiller

# Initialize PortKiller
pk = PortKiller()

# Get a list of active Cloudflare Tunnel connections
tunnels = pk.get_cloudflare_tunnels()

# Print the tunnels
for tunnel in tunnels:
    print(f"Tunnel: {tunnel['name']}, Status: {tunnel['status']}")

Here, we use the get_cloudflare_tunnels method to retrieve a list of active Cloudflare Tunnel connections. The results include the tunnel name and status, providing a clear overview of your current tunnels.

Example 5: Adding a Favorite Port

This example demonstrates how to add a port to your favorites list.

# Import the necessary modules
from portkiller import PortKiller

# Initialize PortKiller
pk = PortKiller()

# Add a port to the favorites list
favorite_port = 8080
pk.add_favorite_port(favorite_port)
print(f"Port {favorite_port} has been added to your favorites list.")

In this example, we use the add_favorite_port method to add port 8080 to our favorites list. This makes it easy to access frequently used ports quickly.

Advanced Usage & Best Practices

To get the most out of PortKiller, consider the following pro tips and optimization strategies:

Use Auto-Refresh Wisely

While the auto-refresh feature is convenient, it can be resource-intensive if set to a very short interval. Adjust the refresh interval based on your needs to balance performance and real-time updates.

Leverage Smart Categorization

PortKiller's smart categorization feature helps you quickly identify the type of service running on a port. Use this feature to your advantage by understanding the categorization logic and customizing it if necessary.

Monitor Watched Ports

For critical ports, use the watched ports feature to receive notifications when the port status changes. This ensures you're always aware of important changes to your services.

Integrate with Your Workflow

PortKiller can be easily integrated into your existing development workflow. Whether you're using it for local development, Kubernetes management, or Cloudflare Tunnel integration, make sure to incorporate PortKiller into your daily routine.
