Documentation
gcp-managed-instance-group
A zonal Managed Instance Group built from a hardened instance template:
Shielded VM, Debian 12, private by default (no external IP). Optional
CPU-based autoscaling and autohealing. The instance template is created
with create_before_destroy, so template changes roll without an outage. Works
with Terraform and OpenTofu (>= 1.6), Google provider >= 7.0, < 8.0.
What you get:
- A
google_compute_instance_template(e2-micro, 10 GBpd-balancedDebian 12, Shielded VM, OS Login) withcreate_before_destroy - A zonal
google_compute_instance_group_managerwith named ports, an update policy, and optional autohealing - An optional
google_compute_autoscaler(CPU target) that owns the group size
