GitHub - kapetacom/portpilot: Forward all your ports

PortPilot Port Forwarding Tool

This is a command-line tool written in Go that enables port forwarding to multiple Kubernetes services. It reads service configuration from a YAML file and establishes port forwarding connections to the specified services.

Prerequisites

Before contributing to this tool, ensure that you have the following prerequisites installed:

Go programming language (https://golang.org/dl/)
Kubernetes client Go library (go get k8s.io/client-go@v0.24.0)

Installation

Binary package

You can always download the latest binaries from the release page

RPM Package

sudo tee -a /etc/yum.repos.d/artifact-registry.repo << EOF
[kapeta-production-yum]
name=kapeta-production-yum
baseurl=https://europe-north1-yum.pkg.dev/projects/kapeta-production/kapeta-production-yum
enabled=1
repo_gpgcheck=0
gpgcheck=0
EOF

Then update the package list and install the tool:

sudo dnf update
sudo dnf install portpilot

Usage

Clone the repository and install the tool using go install.
Create a YAML file named .portpilot.yaml. The YAML file should contain the configuration for the services you want to port forward. Below is an example of the YAML file structure:
```
services:
- name: example-service1
  remotePort: 8080
  localPort: 8081
- name: example-service2
  remotePort: 8888
  localPort: 8889
```
Customize the name, remotePort, and localPort fields for each service as needed.
Open a terminal and navigate to the directory containing the services.yaml file.
Build and run the tool using the following command:

The tool will read the services.yaml file, establish port forwarding connections to the specified services, and print the local URLs for accessing each service.
To stop the port forwarding, press Ctrl+C in the terminal.

Configuration

The Kubernetes configuration is automatically read from the default kubeconfig file location ($HOME/.kube/config). Make sure you have a valid kubeconfig file configured for your cluster.
The tool uses the Kubernetes client Go library to interact with the cluster and perform the port forwarding.

Limitations

The tool assumes the Kubernetes cluster is reachable using the default kubeconfig configuration.
Only the first matching pod is used for each service. If multiple pods match the service selector, only the first pod will be used for port forwarding.
