create a gcloud compute instance with an init script
Raw
README.md

if not done already, type :

$ gcloud init

Assuming you already have ssh keys on your local workstation, create a gcloud specific one by appending your_username: to the file. In the end it will have the following format (we'll name the file gcloud_id_rsa.pub) :

your_username : ssh-rsa kfjdlsfjsdjklfghjkghkflkdjetc...

Then send it to gcloud :

gcloud compute project-info add-metadata --metadata-from-file sshKeys=/your/.ssh/path/gcloud_id_rsa.pub

You can then verify it has been added :

gcloud compute project-info describe

Then create your instance with the following :

gcloud compute instances create you_choose_you_instance_name --metadata-from-file startup-script=/path/to/init.sh

You can also add a specific key to a specific instance, with the following command :

gcloud compute instances add-metadata [INSTANCE_NAME] --metadata-from-file ssh-keys=[KEY_FILE_NAME].pub
