GCP VPC

Objective

This document explains the various types of required policies that grant permissions for users to create or modify resources as part of deploying F5® Distributed Cloud Sites on GCP. This document also provides instructions to create a service account using the GCP cloud formation templates.

Note: Refer to the GCP IAM Documentation for information on the various GCP roles.

GCP VPC Policies

The required policies are managed in the IAM section of GCP portal. The following is the list of permissions required for deploying a GCP VPC site:

Create Role and Apply to Service Account

Perform the steps listed in this chapter to create role with permissions and apply it to a service account.

Prerequisite: Install gcloud command-line tool. See gcloud command-line tool for more information.

The following video tutorial shows how to create a GCP role and apply to service account:

Perform the following steps from CLI:

Step 1: Create the GCP role and permissions required to create F5 Distributed Cloud’s GCP VPC site.
gcloud iam roles create <ROLE_ID> --project=<GCP_PROJECT_ID> --file=f5xc_gcp_vpc_role.yaml
Copied!
  • ROLE_ID - The ID of the custom role to create. For example: f5xc_gcp_vpc_role.
  • GCP_PROJECT_ID - The project of the role you want to create.
  • f5xc_gcp_vpc_role.yaml - Download the custom role definition file here.
Step 2: Create the GCP service account.
gcloud iam service-accounts create <SERVICE_ACCOUNT_NAME>  --display-name=<SERVICE_ACCOUNT_NAME>
Copied!

SERVICE_ACCOUNT_NAME - The internal name of the new service account. For example: f5xc-gcp-vpc-service-account.

Step 3: Get the IAM internal email address for the above-created service account.
gcloud iam service-accounts list | grep <SERVICE_ACCOUNT_NAME> | awk '{print $2}'
Copied!

SERVICE_ACCOUNT_NAME - the service account name used in the previous step.

Step 4: Attach the role created on Step 1 to the IAM service account email address received from Step 3.
gcloud projects add-iam-policy-binding <PROJECT_ID> --member='serviceAccount:<SERVICE_ACCOUNT_IAM_EMAIL_ADDRESS>' --role=projects/<PROJECT_ID>/roles/<ROLE_ID>
Copied!
  • SERVICE_ACCOUNT_IAM_EMAIL_ADDRESS - the output of Step 3.
  • PROJECT_ID - the project ID.
  • ROLE_ID - the Role ID used in Step 1.
Step 5: Create the service account key.
gcloud iam service-accounts keys create --iam-account <SERVICE_ACCOUNT_IAM_EMAIL_ADDRESS> key.json
Copied!
  • SERVICE_ACCOUNT_IAM_EMAIL_ADDRESS - the output of Step 3
  • key.json is the output of the above command and will be used to create GCP Cloud Credentials on F5® Distributed Cloud Console.

Note: Enter the contents of the key.json file in the GCP cloud credential's Secret Info section.
