vpc-sc

VPC Service Control Module

This module allows managing VPC Service Control (VPC-SC) properties:

• Access Policy
• Access Levels
• VPC-SC Perimeters

The Use of this module requires credentials with the correct permissions to use Access Context Manager.

Example VCP-SC standard perimeter

module "vpc-sc" {
  source              = "./modules/vpc-sc"
  organization_id     = "organizations/112233"

        required_access_levels = null
        members        = []
        negate         = false
        regions        = null

Example VCP-SC standard perimeter with one service and one project in dry run mode
