3-networks-hub-and-spoke/production

The purpose of this step is to set up base and restricted shared VPCs with default DNS, NAT (optional), Private Service networking, VPC service controls, onprem Dedicated Interconnect, onprem VPN and baseline firewall rules for environment nonproduction. This version of the Network step will makes usage of the Hub and Spoke network architecture.

Prerequisites

  1. 0-bootstrap executed successfully.
  2. 1-org executed successfully.
  3. 2-environments/envs/production executed successfully.
  4. 3-networks-hub-and-spoke/envs/shared executed successfully.
  5. Obtain the value for the access_context_manager_policy_id variable. Can be obtained by running gcloud access-context-manager policies list --organization YOUR_ORGANIZATION_ID --format="value(name)".

Inputs

Name Description Type Default Required
access_context_manager_policy_id The id of the default Access Context Manager policy created in step 1-org. Can be obtained by running gcloud access-context-manager policies list --organization YOUR_ORGANIZATION_ID --format="value(name)". number n/a yes
domain The DNS name of peering managed zone, for instance 'example.com.'. Must end with a period. string n/a yes
egress_policies A list of all egress policies, each list object has a from and to value that describes egress_from and egress_to.

Example: [{ from={ identities=[], identity_type="ID_TYPE" }, to={ resources=[], operations={ "SRV_NAME"={ OP_TYPE=[] }}}}]

Valid Values:
ID_TYPE = null or IDENTITY_TYPE_UNSPECIFIED (only allow indentities from list); ANY_IDENTITY; ANY_USER_ACCOUNT; ANY_SERVICE_ACCOUNT
SRV_NAME = "*" (allow all services) or Specific Services
OP_TYPE = methods or permissions		 
list(object({
    from = any
    to   = any
  }))
 [] no
enable_hub_and_spoke_transitivity Enable transitivity via gateway VMs on Hub-and-Spoke architecture. bool false no
ingress_policies A list of all ingress policies, each list object has a from and to value that describes ingress_from and ingress_to.

Example: [{ from={ sources={ resources=[], access_levels=[] }, identities=[], identity_type="ID_TYPE" }, to={ resources=[], operations={ "SRV_NAME"={ OP_TYPE=[] }}}}]

Valid Values:
ID_TYPE = null or IDENTITY_TYPE_UNSPECIFIED (only allow indentities from list); ANY_IDENTITY; ANY_USER_ACCOUNT; ANY_SERVICE_ACCOUNT
SRV_NAME = "*" (allow all services) or Specific Services
OP_TYPE = methods or permissions		 
list(object({
    from = any
    to   = any
  }))
 [] no
perimeter_additional_members The list of additional members to be added to the perimeter access level members list. To be able to see the resources protected by the VPC Service Controls in the restricted perimeter, add your user in this list. Entries must be in the standard GCP form: user:[email protected] or serviceAccount:[email protected]. list(string) n/a yes
remote_state_bucket Backend bucket to load Terraform Remote State Data from previous steps. string n/a yes
tfc_org_name Name of the TFC organization string "" no
