# 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>
|
|
```
