Emacs Tramp and GCP

source

In order to get Emacs Tramp to work nicely with gcp's ssh'ing mechanism, some scripts and configurations need to be made.

gssh:

#!/bin/bash

HOST="$1"

if [[ $HOST = *"@"* ]] ; then

USER=$(echo $HOST | cut -d'@' -f1)

HOST=$(echo $HOST | cut -d'@' -f2)

fi

gcloud config list | grep 'Your active'

ZONE=$(gcloud compute instances list |grep -E "^$HOST[[:space:]]" | awk '{print $2}')

echo zone: $ZONE

gcloud compute ssh --zone=$ZONE "$@"

Once that is set, edit .emacs and add a configuration for Tramp to use gssh:

;; TRAMP gcloud ssh

(add-to-list 'tramp-methods

'("gssh"

(tramp-login-program "gssh")

(tramp-login-args (("%h")))

(tramp-async-args (("-q")))

(tramp-remote-shell "/bin/sh")

(tramp-remote-shell-args ("-c"))

(tramp-gw-args (("-o" "GlobalKnownHostsFile=/dev/null")

("-o" "UserKnownHostsFile=/dev/null")

("-o" "StrictHostKeyChecking=no")))

(tramp-default-port 22)))

Done.
