| # Internal Load Balancing in Google Cloud |
| |
| This provides a template for setting up internal load balancing in Google Cloud. It directly mirrors the tutorial in the [GCP Internal Load Balancing Documentation](https://cloud.google.com/compute/docs/load-balancing/internal/). |
| |
| To run the example, |
| |
| * Log in to gcloud with an account that has permission to create the necessary resources using `gcloud init`. |
| * Optionally update `variables.tf` to specify a default value for the `project_name` variable, and check other variables. |
| * Run with a command like this: |
| |
| ``` |
| terraform apply \ |
| -var="region=us-central1" \ |
| -var="region_zone=us-central1-b" \ |
| -var="region_zone_2=us-central1-c" \ |
| -var="project_name=my-project-id-123" \ |
| ``` |
| |
| |
| After you run `terraform apply` on this configuration, it will |
| automatically output the internal IP address of the load balancer. |
| |
| Since the load balancer is only reachable from within the network, ssh into the standalone instance using |
| |
| ``` |
| gcloud compute ssh --zone us-central1-b standalone-instance-1 |
| ``` |
| |
| |
| Using `curl` on the IP address given, the LB should respond with a simple header: |
| |
| ```html |
| <!doctype html><html><body><h1>ilb-instance-X</h1></body></html> |
| ``` |
