What does this script do?

It logs into an GCP organisation, obtains a list of all projects attached to it and then adds them one by one to Dome9 if they don't already exist. It can be used as an Google Function to run daily to sweep up any new projects not already onboarded so cloud estate visibility is maintained.

Standalone Windows executable

If you need to run the tool as a one off and don't want the faff of all the steps below, you can download the ZIP archive. This is a portable version of the tool for Windows only, all batteries included. Download and extract the ZIP and run gcp-onboard.exe. For a Linux or Mac version of this, please open an issue and I will address this. Remember to set environment variables prior to running the tool (see below).

Pre-requisites

To run this script, you will need the following:-

1. Python 3.6 (or newer)

2. A GCP Service Account

   • Create a dedicated security project to manage the Service Account (optional but recommended)
   • Go to IAM, Service Accounts and Create Service Account
   • Create the Service Account with a meaningful name (D9-onboard or similar)
   • Note the e-mail address of the Service Account, you will need this later
   • Click Create
   • Click Continue (no need to assign a role yet)
   • Click Create Key and save as JSON format, the key file will automatically download. Click Done
   • Click the Organisation object from the top drop down box in the GCP Console
   • Click IAM and click Add
   • In the New Members box, copy the e-mail address of the Service Account you created earlier (e.g. myserviceaccount@security-project-9999.iam.gserviceaccount.com), pick the user when they are looked up
   • Add the Service Account to the Project Viewer role and click Save

3. Dome9 API key with admin permissions to add subscriptions (https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doGoviewsolutiondetails=&solutionid=sk144514&partition=General&product=CloudGuard)

   • Dome9 API key
   • Dome9 API secret

4. Run git clone https://github.com/chrisbeckett/gcpd9-autoonboarding.git

5. Run python -m venv gcpd9-autoonboarding

6. Run scripts\activate.bat to enable the Python virtual environment

7. Run pip install -r requirements.txt to install required Python modules

Setup

To run the script locally, you need to set several environment variables which are then read in by the script. This prevents any secret keys being hard coded into the script. Set the following:-

• SET D9_API_KEY=xxxxxxxxxxx
• SET D9_API_SECRET=xxxxxxxxxxxx
• SET GOOGLE_APPLICATION_CREDENTIALS=C:\Users\AUser\Downloads\mykey.json (for example)

Running the script

Simply run the script gcp-onboard.py from the command line

Troubleshooting

Error : "There was an error with the project, please check credentials and that it does not already exist in Dome9"

Fix : Each project to be onboarded needs a minimum number of APIs to be enabled. You can do this with the gcloud tool

    - gcloud services enable cloudapis.googleapis.com
    - gcloud services enable compute.googleapis.com
    - gcloud services enable cloudresourcemanager.googleapis.com

Error : "Unknown error onboarding subscription to Dome9: project-id Status Code: 409"

Fix : This is a cosmetic error and means the project has already been onboarded to Dome9
