First of all, thank you for putting this together! As a developer, I'm very excited about the premise of terraform.

I have followed the guide up to the terraform init command, at which point I get the following output:

$ terraform init
Initializing modules...

Initializing the backend...

Initializing provider plugins...
- Checking for available provider plugins...

Provider "google" v2.3.0 is not compatible with Terraform 0.12.8.

Provider version 2.5.0 is the earliest compatible version. Select it with
the following version constraint:

	version = "~> 2.5"

Terraform checked all of the plugin versions matching the given constraint:
    ~> 2.3.0

Consult the documentation for this provider for more information on
compatibility between provider and Terraform versions.


Provider "google-beta" v2.3.0 is not compatible with Terraform 0.12.8.

Provider version 2.5.0 is the earliest compatible version. Select it with
the following version constraint:

	version = "~> 2.5"

Terraform checked all of the plugin versions matching the given constraint:
    ~> 2.3.0

Consult the documentation for this provider for more information on
compatibility between provider and Terraform versions.


Error: incompatible provider version



Error: incompatible provider version

I briefly tried following the helpful suggestions in the output to change the versions for both the google and google-beta providers to "~> 2.5.0". While that does allow an exit code 0 terraform init command, we see different errors during terraform plan:

$ terraform plan

An argument named "master_authorized_networks_config" is not expected here.
Did you mean to define a block of type "master_authorized_networks_config"?

Would you recommend trying to make the existing main.tf compatible with the newer version of terraform? Or to downgrade terraform to another version? I'll try to dig in more later, but any help much appreciated!

Thank you,
Mike

@golubitsky Yes, I originally wrote this guide for an earlier version of both Terraform and our GCP modules. I'll upgrade it to use the latest versions and hope to ship something this week.
