# Terraform config for creating VPC and subnets
2020-04-23 10:40:08 +08:00
These config will create the following resources on AWS. The VPC CIDR is hard-coded as 10.0.0.0/16. The subnets will sit in different availablity zones for redundancy. Resources are all tagged from a globaltag list.
2020-04-23 10:36:56 +08:00
* 1 VPC
2020-04-23 10:40:08 +08:00
* public subnets in all AZs
* private subnets in all AZs
2020-04-23 10:36:56 +08:00
* 1 internet gateway
* 1 nat gateway

## Revision notes
2020-04-23 10:40:08 +08:00
* Previously terraform plan would fail to compute the count for routing table association. This is now corrected by setting count = number of AZs
