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.
To start, download your credentials from Google Cloud Console; 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:
<h1>www</h1>
And the following at the /video/ url:
<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" \
