A Hub with Spokes that Do Not Export Everything

A hub with no spokes connects nothing; a VPC spoke advertises every subnet to every other spoke unless told otherwise, which is how a sandbox learns the production database range; and site-to-site data transfer routes branches through Google at its rates. Spokes come with the hub, each VPC spoke narrows its exports or says why not, and branch transit is off unless accepted.

This is the operations reference: version drift, dependants and neighbours. For what the module provisions, its inputs and outputs, and how to download it, see the catalogue entry.

Provider drift

This artifact declares no Terraform provider requirements, so there is nothing to drift. Provider freshness applies to Terraform and OpenTofu modules.

What depends on this

No reference architecture names this module, so changing it affects only configurations that reference it directly.

Nearest alternatives

Same cloud, same category. These are what you would weigh against it without changing provider.

The same job on other clouds

Transit Hub on other providers. Useful when the cloud is still open, or when you are pricing a second one. How far a comparison like that can be trusted is covered in comparing clouds.

Installing it

module "gcp_network_connectivity_center" {
  source  = "www.iac-bazaar.com/iac-bazaar/gcp-network-connectivity-center/gcp"
  version = "1.0.0"
}

A registry token is required for the download itself. Installing through the registry protocol has the two credential steps.
