# Content Based Load Balancing in Google Cloud
This provides a template for running an HTTP load balancer that distributes traffic to different instances based on the
path in the request URL. It is based on the tutorial at [https://cloud.google.com/compute/docs/load-balancing/http/content-based-example](https://cloud.google.com/compute/docs/load-balancing/http/content-based-example).
To start, [download your credentials from Google Cloud Console](https://www.terraform.io/docs/providers/google/#credentials); suggested path for downloaded file is `~/.gcloud/Terraform.json`.
Optionally update `variables.tf` to specify a default value for the `project_name` variable, and check other variables.
After you run `terraform apply` on this configuration, it will
automatically output the public IP address of the load balancer.
After your instance registers, the LB should respond with the following at its root:
```html
<h1>www</h1>
```
And the following at the /video/ url:
```html
<h1>www-video</h1>
```
To run, configure your Google Cloud provider as described in
https://www.terraform.io/docs/providers/google/index.html
Run with a command like this:
```
terraform apply \
-var="region=us-central1" \
-var="region_zone=us-central1-f" \
-var="project_name=my-project-id-123" \
-var="credentials_file_path=~/.gcloud/Terraform.json" \
```
