Deploy a VPC with Terraform

Deploy a VPC with Terraform

Learn how to use Infrastructure Manager to deploy a Virtual Private Cloud (VPC).

This quickstart uses a Terraform configuration that is stored in a public GitHub repository. The configuration defines the VPC to provision.

Before you begin

1. Sign in to your Google Account.

   If you don't already have one, sign up for a new account.

2. Install the Google Cloud CLI.

3. To initialize the gcloud CLI, run the following command:

   gcloud init

4. Create or select a Google Cloud project.

   Note: If you don't plan to keep the resources that you create in this procedure, create a project instead of selecting an existing project. After you finish these steps, you can delete the project, removing all resources associated with the project.

   • Create a Google Cloud project:

     gcloud projects create PROJECT_ID

     Replace PROJECT_ID with a name for the Google Cloud project you are creating.

   • Select the Google Cloud project that you created:

     gcloud config set project PROJECT_ID

     Replace PROJECT_ID with your Google Cloud project name.

5. Make sure that billing is enabled for your Google Cloud project.

6. Enable the Infrastructure Manager API:

   gcloud services enable config.googleapis.com

7. Set up authentication:

   1. Create the service account:

      gcloud iam service-accounts create SERVICE_ACCOUNT_NAME

      Replace SERVICE_ACCOUNT_NAME with a name for the service account.

   2. Grant the roles/config.agent IAM role to the service account:

      gcloud projects add-iam-policy-binding PROJECT_ID --member="serviceAccount:SERVICE_ACCOUNT_NAME@PROJECT_ID.iam.gserviceaccount.com" --role=roles/config.agent

      Replace the following:

      • SERVICE_ACCOUNT_NAME: the name of the service account
      • PROJECT_ID: the project ID where you created the service account
      Note: The --role flag affects which resources the service account can access in your project. You can revoke these roles or grant additional roles later.
8. Install the Google Cloud CLI.

9. To initialize the gcloud CLI, run the following command:

   gcloud init

10. Create or select a Google Cloud project.

    Note: If you don't plan to keep the resources that you create in this procedure, create a project instead of selecting an existing project. After you finish these steps, you can delete the project, removing all resources associated with the project.

    • Create a Google Cloud project:

      gcloud projects create PROJECT_ID

      Replace PROJECT_ID with a name for the Google Cloud project you are creating.

    • Select the Google Cloud project that you created:

      gcloud config set project PROJECT_ID

      Replace PROJECT_ID with your Google Cloud project name.

11. Make sure that billing is enabled for your Google Cloud project.

12. Enable the Infrastructure Manager API:

    gcloud services enable config.googleapis.com

13. Set up authentication:

    1. Create the service account:

       gcloud iam service-accounts create SERVICE_ACCOUNT_NAME

       Replace SERVICE_ACCOUNT_NAME with a name for the service account.

    2. Grant the roles/config.agent IAM role to the service account:

       gcloud projects add-iam-policy-binding PROJECT_ID --member="serviceAccount:SERVICE_ACCOUNT_NAME@PROJECT_ID.iam.gserviceaccount.com" --role=roles/config.agent

       Replace the following:

       • SERVICE_ACCOUNT_NAME: the name of the service account
       • PROJECT_ID: the project ID where you created the service account
       Note: The --role flag affects which resources the service account can access in your project. You can revoke these roles or grant additional roles later.

Grant permissions for resources in the configuration

You have granted permissions needed to run Infra Manager, but you also need to grant permissions that are specific to the resources described in the configuration you are deploying.

Grant permissions for the VPC, which is the resource defined in the Terraform configuration.

gcloud projects add-iam-policy-binding PROJECT_ID \
    --member=serviceAccount:SERVICE_ACCOUNT_NAME@PROJECT_ID.iam.gserviceaccount.com \
    --role=roles/compute.networkAdmin

Replace the following:

• SERVICE_ACCOUNT_NAME: the name of the service account.
• PROJECT_ID: your project ID.

Preview the deployment

Before you create a deployment, you can create a preview of the deployment. You can use this preview to verify the resources that are planned to be provisioned.

The following command has four values populated that don't have a default value. These values are: your project ID, the service account name, the location us-central1, and the name quickstart-vpc for the network you're creating.

To create a preview, use the following command:

    gcloud infra-manager previews create projects/PROJECT_ID/locations/us-central1/previews/quickstart-preview \
        --service-account projects/PROJECT_ID/serviceAccounts/SERVICE_ACCOUNT_NAME@PROJECT_ID.iam.gserviceaccount.com \
        --git-source-repo=https://github.com/terraform-google-modules/terraform-google-network \
        --git-source-directory=modules/vpc \
        --git-source-ref=master \
        --input-values=project_id=PROJECT_ID,network_name=quickstart-vpc

After you create a preview, you can review the preview results. This quickstart skips this step, but you can see Export and view preview results if you want more details.

Create a deployment

Use Infra Manager to create a deployment. This means that Infra Manager provisions the resources that are defined in the Terraform configuration.

The configuration for this quickstart has four values that don't have a default value. The following command adds these values: your project ID, the service account name, the location us-central1, and the name quickstart-vpc for the network you're creating.

gcloud infra-manager deployments apply projects/PROJECT_ID/locations/us-central1/deployments/quickstart-deployment \
    --service-account=projects/PROJECT_ID/serviceAccounts/SERVICE_ACCOUNT_NAME@PROJECT_ID.iam.gserviceaccount.com \
    --git-source-repo=https://github.com/terraform-google-modules/terraform-google-network \
    --git-source-directory=modules/vpc \
    --git-source-ref=master \
    --input-values=project_id=PROJECT_ID,network_name=quickstart-vpc

When the deployment is done, you see:

Creating the deployment...done

The VPC is now created and configured as described in the configuration.

View the build results in Cloud Build

To view the Cloud Build job that Infra Manager used to create the deployment, open the Build History page in the Google Cloud console:

Open the Build History page

View the status of the deployment

Now that the deployment is done, you can view its description to review information about it, including the state.

View the description of the deployment:

gcloud infra-manager deployments describe projects/PROJECT_ID/locations/us-central1/deployments/quickstart-deployment

The output has details about the deployment, including the timestamp of the deployment, the name of the latest revision, and the state.

For the state, you see ACTIVE.

View details about the provisioned VPC

View details about the provisioned VPC:

gcloud infra-manager resources list --revision=projects/PROJECT_ID/locations/us-central1/deployments/quickstart-deployment/revisions/REVISION_ID

Replace REVISION_ID with the ID of the latest revision. This ID is r-0, unless you deployed multiple times. You can see the ID of the latest revision in the deployment description in the previous section.

View the VPC in the console

View the VPC in the console:

Go to VPC networks

You see the VPC named quickstart-vpc. This is the VPC that Infra Manager provisioned.

Clean up

To avoid incurring charges to your Google Cloud account for the resources used on this page, make sure that you delete resources that you no longer need.

Delete the VPC

Delete the VPC and the metadata about the deployment:

gcloud infra-manager deployments delete projects/PROJECT_ID/locations/us-central1/deployments/quickstart-deployment

Optional: Delete the project

If you deployed the solution in a new Google Cloud project, and if you no longer the project, then delete it by completing the following steps:

Caution: If you delete a project, all the resources in the project are permanently deleted.

1. In the Google Cloud console, go to the Manage resources page.

   Go to Manage resources

2. In the project list, select the project that you want to delete, and then click Delete.
3. At the prompt, type the project ID, and then click Shut down.
