Need Help With Emacs Tramp Mode For 'gcloud compute ssh'

[Samuel Banya]

Hello there,

I have looked high and low on the internet, and can't find a decent answer on 
how to utilize Tramp Mode for 'gcloud compute ssh'.

This is the command I need to run for work, since I remote into gcloud (GCP) 
based jump boxes, so I need to use the '--project' parameter accordingly:
gcloud compute ssh --project ops-dist-(client's environment name) (client's 
environment name)-cli

I have the following present in my Emacs config so far, but am completely stuck 
as all there's to go off is the source code itself, and I really only use Org 
Mode and Emacs for notes, and super light programming:

** WORK-SPECIFIC Add 'tramp' to easily ssh into gcp jumpbox and ssh into 
'aa-master'
#+BEGIN_SRC emacs-lisp
  (use-package tramp
    :ensure t
    :config
    (add-to-list 'tramp-methods
'("gcssh"
   (tramp-login-program "gcloud compute ssh")
   (tramp-login-args (("%h --project example-project example-project-cli")))
   (tramp-async-args (("-q")))
   (tramp-remote-shell "/bin/bash")
   (tramp-remote-shell-args ("-c"))
   (tramp-gw-args (("-o" "GlobalKnownHostsFile=/dev/null")
   ("-o" "UserKnownHostsFile=/dev/null")
   ("-o" "StrictHostKeyChecking=no")))
   (tramp-default-port 22))))

  (defun gcp-box-connect ()
    (interactive)
    (find-file "/gcssh:compute-instance:/path/to/filename.clj"))

  ;; NOTE: Uncommenting when I figure out the full path to what I need to add 
and will most likely add it to a 'secrets' file:
  ;; Suggested format:
  ;; C-x C-f /gcssh:compute-instance:/path/to/filename.clj
  (global-set-key (kbd "C-M-g") 'gcp-box-connect)
