Configure Pub/Sub notifications

This document describes how to set up notifications for updates to notes and occurrences.

Artifact Analysis provides notifications via Pub/Sub for vulnerabilities found by automated scanning and for other metadata. When a note or occurrence is created or updated, a message is published to the corresponding topic for each API version. Use the topic for the API version you are using.

Before you begin

Sign in to your Google Cloud account. If you're new to Google Cloud, create an account to evaluate how our products perform in real-world scenarios. New customers also get $300 in free credits to run, test, and deploy workloads.

In the Google Cloud console, on the project selector page, select or create a Google Cloud project.

Roles required to select or create a project

• Select a project: Selecting a project doesn't require a specific IAM role—you can select any project that you've been granted a role on.
• Create a project: To create a project, you need the Project Creator role (roles/resourcemanager.projectCreator), which contains the resourcemanager.projects.create permission. Learn how to grant roles.

Go to project selector

Enable the Container Analysis API.

Roles required to enable APIs

To enable APIs, you need the serviceusage.services.enable permission. If you created the project, then you likely already have this permission through the Owner role (roles/owner). Otherwise, you can get this permission through the Service Usage Admin role (roles/serviceusage.serviceUsageAdmin). Learn how to grant roles.

Enable the API

Install the Google Cloud CLI.

If you're using an external identity provider (IdP), you must first sign in to the gcloud CLI with your federated identity.

To initialize the gcloud CLI, run the following command:

gcloud init

In the Google Cloud console, on the project selector page, select or create a Google Cloud project.

1. Learn how to set up access control for metadata in your project. Skip this step if you only consume metadata from occurrences created by Artifact Analysis container scanning.

Create Pub/Sub topics

After you activate the Artifact Analysis API, Artifact Analysis automatically creates Pub/Sub topics with the following topic IDs:

• container-analysis-notes-v1
• container-analysis-occurrences-v1

If the topics were accidentally deleted or are missing, you can add them yourself. For example, the topics might be missing if your Google Cloud organization has an organization policy constraint that requires encryption with customer-managed encryption keys (CMEK). When the Pub/Sub API is in the deny list of this constraint, services cannot automatically create topics with Google-owned and Google-managed encryption keys.

To create the topics with Google-owned and Google-managed encryption keys:

gcloud pubsub topics create projects/PROJECT_ID/topics/container-analysis-notes-v1
gcloud pubsub topics create projects/PROJECT_ID/topics/container-analysis-occurrences-v1

To create the topics with CMEK encryption, see the Pub/Sub instructions for encrypting topics.

Anytime a note or an occurrence is created or updated, a message is published to the respective topic, though you must also create a Pub/Sub subscription to listen for events and receive messages from the Pub/Sub service.

Create Pub/Sub subscriptions

To listen to events, create a Pub/Sub subscription associated with the topic:

gcloud pubsub subscriptions create \
    --topic container-analysis-occurrences-v1 occurrences

gcloud pubsub subscriptions pull \
    --auto-ack occurrences

import com.google.cloud.pubsub.v1.Subscriber;
import com.google.cloud.pubsub.v1.SubscriptionAdminClient;
