     1  # Basic Two-Tier Architecture in Google Cloud
     2  
     3  This provides a template for running a simple two-tier architecture on Google Cloud.
     4  The premise is that you have stateless app servers running behind
     5  a load balancer serving traffic.
     6  
     7  To simplify the example, this intentionally ignores deploying and
     8  getting your application onto the servers. However, you could do so either via
     9  [startup script](http://terraform.io/docs/providers/google/r/compute_instance.html#metadata_startup_script) or
    10  [provisioners](https://www.terraform.io/docs/provisioners/) and a configuration
    11  management tool, or by pre-baking configured images with
    12  [Packer](https://packer.io/docs/builders/googlecompute.html).
    13  
    14  After you run `terraform apply` on this configuration, it will
    15  automatically output the public IP address of the load balancer.
    16  After your instance registers, the LB should respond with a simple header:
    17  
    18  ```html
    19  <h1>Welcome to instance 0</h1>
    20  ```
    21  
    22  The index may differ once you increase `count` of `google_compute_instance`
    23  (i.e. provision more instances).
    24  
    25  To run, configure your Google Cloud provider as described in
    26  
    27  https://www.terraform.io/docs/providers/google/index.html
    28  
    29  Run with a command like this:
    30  
    31  ```
    32  terraform apply \
    33  	-var="region=us-central1" \
    34  	-var="region_zone=us-central1-f" \
    35  	-var="project_name=my-project-id-123" \
    36  	-var="account_file_path=~/.gcloud/Terraform.json" \
    37  	-var="public_key_path=~/.ssh/gcloud_id_rsa.pub" \
    38  	-var="private_key_path=~/.ssh/gcloud_id_rsa"
    39  ```
