HTTPS Content-Based Load Balancer with Terraform
In this lab, you will create an HTTPS load balancer to forward traffic to a custom URL map. The URL map sends traffic to the region closest to you with static assets being served from a Cloud Storage bucket. The TLS key and certificate is generated by Terraform using the TLS provider.
The following is a diagram of the architecture you will be creating:
In this lab, you will:
- Learn about the load balancing modules for Terraform
- Configure Terraform in the Google Cloud environment
- Create a global HTTPS Content-Based Load Balancer
Setup and requirements
Before you click the Start Lab button
Read these instructions. Labs are timed and you cannot pause them. The timer, which starts when you click Start Lab, shows how long Google Cloud resources will be made available to you.
This hands-on lab lets you do the lab activities yourself in a real cloud environment, not in a simulation or demo environment. It does so by giving you new, temporary credentials that you use to sign in and access Google Cloud for the duration of the lab.
To complete this lab, you need:
- Access to a standard internet browser (Chrome browser recommended).
- Time to complete the lab---remember, once you start, you cannot pause a lab.
How to start your lab and sign in to the Google Cloud Console
Click the Start Lab button. If you need to pay for the lab, a pop-up opens for you to select your payment method. On the left is the Lab Details panel with the following:
- The Open Google Console button
- Time remaining
- The temporary credentials that you must use for this lab
- Other information, if needed, to step through this lab
Click Open Google Console. The lab spins up resources, and then opens another tab that shows the Sign in page.
Tip: Arrange the tabs in separate windows, side-by-side.
Note: If you see the Choose an account dialog, click Use Another Account.
If necessary, copy the Username from the Lab Details panel and paste it into the Sign in dialog. Click Next.
Copy the Password from the Lab Details panel and paste it into the Welcome dialog. Click Next.
Important: You must use the credentials from the left panel. Do not use your Google Cloud Skills Boost credentials. Note: Using your own Google Cloud account for this lab may incur extra charges.
Click through the subsequent pages:
- Accept the terms and conditions.
- Do not add recovery options or two-factor authentication (because this is a temporary account).
- Do not sign up for free trials.
After a few moments, the Cloud Console opens in this tab.
Activate Cloud Shell
Cloud Shell is a virtual machine that is loaded with development tools. It offers a persistent 5GB home directory and runs on the Google Cloud. Cloud Shell provides command-line access to your Google Cloud resources.
- Click Activate Cloud Shell at the top of the Google Cloud console.
When you are connected, you are already authenticated, and the project is set to your PROJECT_ID. The output contains a line that declares the PROJECT_ID for this session:
gcloud is the command-line tool for Google Cloud. It comes pre-installed on Cloud Shell and supports tab-completion.
(Optional) You can list the active account name with this command:
Your output should now look like this:
(Optional) You can list the project ID with this command:
gcloud, in Google Cloud, refer to the gcloud CLI overview guide.
Task 1. Install Terraform
Your Cloud Shell comes prepackaged with
Terraform but you will install it to ensure you have the correct version for the example code in this lab.
Download and unzip
Move the executable into your
Task 2. Clone the sample repository
In Cloud Shell, clone the

Task 3. Run Terraform
Initialize a working directory
terraform init command is used to initialize a working directory containing Terraform configuration files. This command performs several different initialization steps to prepare a working directory for use. This command is always safe to run multiple times, to bring the working directory up to date with changes in the configuration.
Run the command:
Create an execution plan
terraform plan command is used to create an execution plan. Terraform performs a refresh, unless explicitly disabled, and then determines what actions are necessary to achieve the desired state specified in the configuration files.
This command is a convenient way to check whether the execution plan for a set of changes matches your expectations without making any changes to real resources or the state. For example,
terraform plan might be run before committing a change to version control, to create confidence that it will behave as expected.
Make sure to replace
<PROJECT_ID>with your lab provided Project ID:
-out argument can be used to save the generated plan to a file for later execution with
List out current directory content. You will see the saved Terraform plan (
Apply the changes
terraform apply command is used to apply the changes required to reach the desired state of the configuration, or the pre-determined set of actions generated by a terraform plan execution plan.
Apply the Terraform plan:
Example output (yours will differ):
Verify the resources created by Terraform:
In the Navigation menu navigate to Network services > Load Balancing.
Wait until you see the green checkmark in the Backends column.
Click on ml-bk-ml-mig-bkt-s-lb load balancer and check the details.
Run the following to get the external URL:
- Click on the
EXTERNAL_IPlink that is returned to open the load balancer URL in a new browser tab.
You should see the Google Cloud logo and instance details from the group closest to your geographical region.
Click Check my progress to verify the objective.
- Now append the URL with
Your final URLs should look like (make sure to replace
EXTERNAL_IP with your load balancer IP):
group1: You should see the Google Cloud logo and instance details from the group in
group2: You should see the Google Cloud logo and instance details from the group in
group3: You should see the Google Cloud logo and instance details from the group in
In this lab, you learned how to configure load balancing modules in Terraform. You then used the modules to create a global HTTPS Content-Based Load Balancer, and used it to test its response to the group closest to your geographical region.
