This document explains how to enable the Container Scanning API, push an image to Artifact Registry, and see the list of vulnerabilities found in the image.
Artifact Analysis stores vulnerability information as notes. An occurrence is created for each instance of a note associated with an image. See the overview and pricing documents for more information.

- Create a Docker repository in Artifact Registry and push a container image
with your Go code to the repository. If you are not familiar with
Artifact Registry, see the
Docker quickstart.
For information on how you can use Cloud Build to build and containerize your Go applications, see Build Go applications.
Artifact Analysis does not automatically scan existing images. To scan an existing image, you must push it again.
View the image vulnerabilities
Artifact Analysis scans new images when they're uploaded to Artifact Registry. This scan extracts information about the packages in the container.
You can view vulnerability occurrences for your images in Artifact Registry using the Google Cloud console, Google Cloud CLI, or the Container Analysis API. If an image has vulnerabilities, you can then obtain the details.
Artifact Analysis only updates the metadata for images that were pushed or pulled in the last 30 days. Artifact Analysis archives metadata that is older than 30 days.To re-scan an image with archived metadata, pull that image. Refreshing metadata can take up to 24 hours.
View occurrences in the Google Cloud console
To see the vulnerabilities in an image:
Get the list of repositories.
In the repositories list, click a repository.
In the images list, click an image name.
Vulnerability totals for each image digest are displayed in the Vulnerabilities column.
To view the list of vulnerabilities for an image, click the link in the Vulnerabilities column.
The Scan results section displays a summary of the package types scanned, total vulnerabilities, vulnerabilities with fixes available, vulnerabilities without fixes, and effective severity.
The table of vulnerabilities lists the Common Vulnerabilities and Exposures (CVE) name for each vulnerability found, the effective severity, Common Vulnerability Scoring System (CVSS) score, fixes (when available), the name of the package that contains the vulnerability, and the package type.
You can filter and sort these files to check a specific file, directory, or type of file by file extension.
Google Cloud console displays up to 1200 vulnerabilities in this table. If your image has more than 1200 vulnerabilities, you must use gcloud or the API to view the full list.
For details about a specific CVE, click the CVE name.
To view vulnerability occurrence details such as version number and affected location, click View or View Fixed in the row with the name of the vulnerability. The link text is View for vulnerabilities without a fix, and View Fixed for vulnerabilities where a fix has been applied.
View occurrences using gcloud
To view occurrences for an image in Artifact Registry, run the following command:
gcloud artifacts docker images list --show-occurrences \
LOCATION-docker.pkg.dev/PROJECT_ID/REPOSITORY/IMAGE_ID
Where:
- LOCATION is the regional or multi-regional location of the repository.
- PROJECT_ID is your Google Cloud console project ID.
- REPOSITORY is the name of the repository where the image is stored.
IMAGE_ID is the name of the image in the repository. You cannot specify an image tag with this command.
By default, the command returns the 10 most recent images. To show a different number of images, use the
--show-occurrences-from
flag. For example, the following command returns the 25 most recent images.gcloud artifacts docker images list --show-occurrences-from=25 \ us-central1-docker.pkg.dev/my-project/my-repo/my-image
To view vulnerabilities for an image tag or a layer:
gcloud artifacts docker images describe \
LOCATION-docker.pkg.dev/PROJECT_ID/REPOSITORY/IMAGE_ID:TAG \
--show-package-vulnerability
or
gcloud artifacts docker images describe \
LOCATION-docker.pkg.dev/PROJECT_ID/REPOSITORY/IMAGE_ID@sha256:HASH \
--show-package-vulnerability
Where:
- LOCATION is the regional or multi-regional location of the repository.
- PROJECT_ID is your Google Cloud console project ID.
- REPOSITORY is the name of the repository where the image is stored.
- IMAGE_ID is the name of the image in the repository.
- TAG is the image tag about which you want to get information.
HASH is the image digest.
Artifact Analysis returns results including the
packageType
.
To filter the vulnerability occurrences:
gcloud artifacts docker images list --show-occurrences \
LOCATION-docker.pkg.dev/PROJECT_ID/REPOSITORY/IMAGE_ID \
--occurrence-filter=FILTER_EXPRESSION
Where:
- LOCATION is the regional or multi-regional location of the repository.
- PROJECT_ID is your Google Cloud console project ID.
- REPOSITORY is the name of the repository where the image is stored.
- IMAGE_ID is the name of the image in the repository.
- FILTER_EXPRESSION is a sample filter expression in the format explained in Filtering vulnerability occurrences.

curl -X GET -H "Content-Type: application/json" -H \
"Authorization: Bearer $(gcloud auth print-access-token)" \
https://containeranalysis.googleapis.com/v1/projects/PROJECT_ID/occurrences/OCCURRENCE_ID
View vulnerabilities in Cloud Build
If you're using Cloud Build, you can also view image vulnerabilities in the Security insights side panel within the Google Cloud console.
The Security insights side panel provides a high-level overview of build security information for artifacts stored in Artifact Registry. To learn more about the side panel and how you can use Cloud Build to help protect your software supply chain, see View build security insights.
Filter occurrences
You can use filter strings in the gcloud
commands and the
Artifact Analysis API to filter occurrences before viewing them. The
following sections describe the supported search filters.
View occurrences of a specific type
You can use the kind
value to filter by occurrence type. See available
kinds.
The following examples demonstrate how to filter to deployment occurrences for an image:
gcloud
In the gcloud CLI, run the following:
gcloud artifacts docker images list --show-occurrences \
--occurrence-filter='kind="DEPLOYMENT"' --format=json \
LOCATION-docker.pkg.dev/PROJECT_ID/REPOSITORY/IMAGE_ID
Where:
DEPLOYMENT
is the kind of occurrence.- LOCATION is the regional or multi-regional location of the repository.
- PROJECT_ID is your Google Cloud console project ID.
- REPOSITORY is the name of the repository where the image is stored.
- IMAGE_ID is the name of the image in the repository.
API
In your API query, use the following filter expression:
kind="DEPLOYMENT" AND resourceUrl="RESOURCE_URL"
Where:
DEPLOYMENT
is the kind of occurrence.- RESOURCE_URL is the complete URL of the image in the format
https://LOCATION-docker.pkg.dev/PROJECT_ID/REPOSITORY/IMAGE_ID@sha256:HASH
.
You can use the hasPrefix
function to filter with a wider scope.
For example, the following filters to occurrences of a specific kind across many images:
kind="NOTE_KIND" AND has_prefix(resourceUrl, "RESOURCE_URL_PREFIX")
Where:
- RESOURCE_URL_PREFIX specifies a substring from a resource URL.
- To filter for all versions of an image, omit the image digest. Use the format:
https://LOCATION-docker.pkg.dev/PROJECT_ID/REPOSITORY/IMAGE_ID@
- To filter for all images in a project, only specify the resource location and project. Use the format:
https://LOCATION-docker.pkg.dev/PROJECT_ID/
- To filter for all versions of an image, omit the image digest. Use the format:
View vulnerability occurrences
