Launching iTerm2 from macOS Finder

(Based on info from Peter Downs' gitub but with modified behavior to open a new terminal window for each invocation instead of reusing an already open window.)

The following three ways to launch an iTerm2 window from Finder have been tested on iTerm2 version 3+ running on macOS Mojave+.

Requirements

1. socat
2. kubectl with proper ~/.kube/config that can connect to your cluster
3. Working knowledge of kubectl client
4. OpenSSH client

How does it work?

1. kubectl does port forwarding to sshd port of your pod. I'm using pm2 process managed to keep my services alive in my workstation container. If you have only sshd, easiest to use is dropbear
2. ProxyCommand of OpenSSH client uses socat to redirect two way fd - to forwarded port of kubectl
3. Voila! You are in

HOW TO

Why

Copy Paste (CTRL+C) command doesn't work for Linux terminals as CTRL+C is used for SIGINT signal to stop/interrupt works on Linux shell.

Prerequisites

You are on Windows but need to have Linux shell like bash or zsh and using one of popular terminal emulators

Steps

1. Download and Install AHK (AutoHotKey) // https://autohotkey.com/
2. Put copy-paste.ahk anywhere in your machine and double click after saving it.
3. Voila, now Alt + C (same position as CMD + C) will work just like Macbook on most of Linux Terminal emulators on Windows (tested with Cmder, MinTTY, Hyper.JS)
