# 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" \
|
|
``` |
