Providing metadata for images

You can choose to provide your own vulnerability metadata to Container Analysis to satisfy a specific business need. For example, an organization that provides security management for their customers' Docker containers can use Container Analysis to store and retrieve security-related metadata for those images.

Follow the steps below to provide custom vulnerability metadata for your images using the Container Analysis API. You can use the same instructions to store and retrieve any kind of metadata that Container Analysis supports.

Before you begin

  1. Enable the Container Analysis API.

  2. Read the Container Analysis overview.

  3. Read how to configure Container Analysis access control for your projects.

Creating vulnerability notes and occurrences for projects

This section explains how third-party vulnerability providers can create notes and occurrences for their user's projects.

As a provider, you will create a note in your project for each vulnerability kind, and you will create an occurrence in your customer's project for an occurrence of that vulnerability.

Creating notes

To create a note:

API

  1. Create a file named note.json with vulnerability description and details. The following code shows an example note.json file:

         {
             "shortDescription": "A brief Description of the note",
             "longDescription": "A longer description of the note",
             "kind": "PACKAGE_VULNERABILITY",
             "vulnerabilityType": {
                 "details": [
                 {
                     "package": "libexempi3",
                     "cpeUri": "cpe:/o:debian:debian_linux:7",
                     "minAffectedVersion": { "name": "2.5.7", "revision": "1"},
                     "maxAffectedVersion": { "name": "2.5.9", "revision": "1"},
                 },
                 {
                     "cpeUri": "something else"
                 }
                 ]
             }
         }
    
  2. Run the following curl command to create a note where [PROVIDER_PROJECT_ID] is your project ID:

    curl -X POST -H "Content-Type: application/json" -H \
        "Authorization: Bearer $(gcloud auth print-access-token)" \
        https://containeranalysis.googleapis.com/v1/projects/[PROVIDER_PROJECT_ID]/notes?note_id=[NOTE_ID] -d @note.json

Creating occurrences for the notes

To create occurrences for a note:

API

  1. Create a file named occurrence.json with the following contents:

         {
             "resourceUrl": "<resource_url>",
             "noteName": "projects/<provider-project-id>/notes/<note_id>",

                     "affectedLocation": {
                         "cpeUri": "7",
                         "package": "a",
                         "version":  {
                             "epoch": "1"

                 }]
             }
         }
    
  2. Run the following curl command where [CUSTOMER_PROJECT_ID] is your customer's project ID:

    curl -v -X POST -H "Content-Type: application/json" -H \
        "Authorization: Bearer $(gcloud auth print-access-token)" \

Get all occurrences for a specific note

You can view all occurrences of a specific vulnerability across your customer's projects using notes.occurrences.list().

API

To list all the occurrences for a note, send a GET request as follows:

GET https://containeranalysis.googleapis.com/v1/projects/PROJECT_ID/notes/NOTE_ID/occurrences

Refer to the projects.notes.occurrences.list API endpoint for complete details.
