Guidelines

In order to make this discovery module work, the following naming convention should be adopted:

Common variables referenced in naming standards

Variable RegExp Example
<availability_zone> [a-z]{2}-[a-z]{1,}-[1-2][a-f] us-east-1a, us-west-2c, eu-west-1a

VPC Resources Naming Standards

AWS Resource Resource Naming Comment Example
VPC <vpc_name>-vpc mycloud
Private Subnets <vpc_name>-private-<availability_zone> Tag: Tier=private mycloud-private-us-east-1b
Public Subnets <vpc_name>-public-<availability_zone> Tag: Tier=public mycloud-public
Private Route Tables <vpc_name>-private-<availability_zone> mycloud-private-us-east-1b
Public Route Tables <vpc_name>-public mycloud-public
Nat Gateway <vpc_name>-nat-<availability_zone> mycloud-nat-us-east-1b
Internet Gateway <vpc_name>-igw mycloud-igw
