Create a subnet in GCP

To be able to deploy VMs in Google Cloud Platform, you will need to add private subnet IP addresses to your VMs. To obtain these IP addresses, create subnets of your global networks, and assign them to your virtual datacenters.

You can set a subnet as the default network to automatically create IP addresses if the user does not create a VM network configuration.

To create a custom mode subnet:

1. Go to myCloud virtual datacenters view → Global
2. Select a Google provider
3. Select a global network
4. On the Subnets page, click the + add button and complete the dialog
