GCP Compute Engine Driver

Preevy can provision virtual machines on GCP using the gce driver. Google compute engine provisioning time for a VM is usually less than a minute, the default machine size in use is e2-small (2GB, 2vCpu) which costs around $12 per month. Google Compute also offers a $300 free credit for new users which is suited for trying out preevy.

Supported options

option	flag	description	required	default
project-id	--gce-project-id	Google Cloud project ID	required	(none)
zone	--gce-zone	Google Cloud zone in which resources will be provisioned	required	(none)
machine-type	--gce-machine-type	Machine type to be provisioned	optional	e2-small

Overriding options

Similar to other drivers, options are saved in the Preevy profile to be used as default values for all operations.

Options can be overridden for a specific compose file by adding them to the x-preevy section:

services:
  ...
x-preevy:
  driver: gce
  drivers:
    gce:
      machine-type: e2-medium

Options can also be overridden using a CLI flag per command execution:

preevy up --gce-machine-type=e2-medium

Credentials Configuration

Preevy uses the Google SDK which uses application default credentials (https://cloud.google.com/docs/authentication/application-default-credentials). The simplest way is to use gcloud auth application-default login command.

Also, you can check out the video below for a step-by-step guide on how to configure GCP credentials and use them with Preevy.
