Requirements for installation from source

The following things are required when there is no wheel available for the target system.

• Rust installed and available in the path (https://www.rust-lang.org/tools/install)
• Python (at least v3.7 - below was never tested but might work)

Pip knows how to install portforward.

pip install portforward

Quickstart

import requests

import portforward


def main():
    namespace = "test"
    pod_name = "web"  # You can also use a service name instead
    local_port = 9000  # from port
    pod_port = 80  # to port

    # No path to kube config provided - will use default from $HOME/.kube/config
    with portforward.forward(namespace, pod_name, local_port, pod_port):
        response = requests.get("http://localhost:9000")
        print(f"Done: \n'{response.status_code}'\n'{response.text[:20]}...'")


if __name__ == "__main__":
    main()

Features

• Native Kubernetes port-forwarding with the .kube/config from the home dir or any other path to config.
• Portforward for pods and services - the lib will first look for a pod with matching name then for a service
• Waiting for a pod to become ready
• Multiple forwards per pod or service
• As context manager, sync or async client

Development

In case you want to develop on this library itself please take a look at the CONTRIBUTING page.
