# This is an example script for setting up MATLAB Network License Manager on Google cloud platform.

    # Sample Requirements:
        # OS: Ubuntu20
        # Compute: n2-standard-4 machine
        # Number of nodes : 1
        # Existing GCP VPC & Subnet : True/False
        # Version : R2021a

## Recommended practice is to use the latest version of License manager.
# This supports previous version license checkout as well.
Version="R2021a"

# VM Operating system
BootDiskOS="ubuntu20"

## Set up a MATLAB Network License Manager on Google Cloud
Create_VPC=true
Create_Subnet=true

## The existing networks will be used only if above 2 inputs are set to false
Existing_VPC_network="tf-test-network"

# Configure variable `machine_types` with instance type
Instance="n2-standard-4"

# Unique tag for naming resources
TS=$(date +%s) && \
BUILD_TAG="mlm-${Version:(-3)}-${BootDiskOS}-${TS}"

# Initialize and Validate Terraform scripts
echo Initializing Terraform ...
