default VPC Requirement

[hasibeg]

Thanks for stopping by to let us know something could be better!

Is your feature request related to a problem? Please describe.
Sometimes the new projects don't have the default VPC network by default and the create script fails because GCE instances cannot be created.

Describe the solution you'd like
It might be good to mention that "default" auto VPC is a pre-req for the script to create the sandbox environment

Describe alternatives you've considered
Another alternative could be creating it as part of the terraform script if it doesn't exist.

@hasibeg hello, thank you for your suggestion. we will add support for the custom network and subnetwork arguments in CLI (sandboxctl) in the next minor version (0.10).

@hasibeg I am in the same case, with an Org Policy removing the default VPC network from new projects. I have to create it manually, either from the console or with a gcloud command, then request a new provisioning.

@minherz These two options would definitely be good additions. I am not sure they solve the initial problem though. Delegating the creation of the default network to Terraform seems like a better, more seamless option.

@minherz @hasibeg I pushed #1052 to create the default network if it does not exist already, to ensure backward compatibility with a non-breaking change.

Thank you @lvaylet and the team for the update !

Fixed by #1052

It seems that when auto_create_subnetworks is omitted, the network is created without subnetworks. As a result, GKE cluster cannot be created because subnetworks are missing.
