Modular Internal Load Balancer for GCE using forwarding rules.

• TCP load balancer
• HTTP/S load balancer
• Internal load balancer

This module is meant for use with Terraform 1.3+ and tested using Terraform 1.3+. If you find incompatibilities using Terraform >=1.3, please open an issue.

The following guides are available to assist with upgrades:
