gcp-cloud-nat
A Cloud NAT gateway for one region: a google_compute_router plus a
google_compute_router_nat so private instances (no external IPs) get outbound
internet access. Sensible, secure defaults: auto-allocated NAT IPs, NAT
all subnet ranges, and logging on. Works with Terraform and
OpenTofu (>= 1.6), Google provider >= 7.0, < 8.0.
What you get:
- A Cloud Router (optionally BGP-enabled) in the chosen region
- A Cloud NAT gateway:
AUTO_ONLYIP allocation,ALL_SUBNETWORKS_ALL_IP_RANGESby default, tunable idle timeouts and per-VM port minimums - Cloud NAT logging (
ERRORS_ONLYby default)
Requirements
| Requirement | Version |
|---|---|
| Terraform / OpenTofu | >= 1.6 |
