This module will help provision an managed instance group on GCP with Terraform

This module will:

• Create a instance template
• Create a managed instance group with created instance template
• Adding default service account, and roles for service account

Usages

Attentions: There are two ways to set image for instance template, you could use your own image, or base image on GCP. To use base image, please define family_image and project_image_id as example below. Otherwise, you must set image by use source_image.
