    Scan images in Alibaba Cloud Container Registry

    Configure Prisma Cloud to scan your Alibaba Cloud Container Registry. First, create a service account, and then specify the scan parameters.

    Create a service account

    Create a service account so Prisma Cloud can access your registry. Prisma Cloud needs the
    AliyunContainerRegistryReadOnly
     permission policy to query, download, and scan the images in your registry.
    1. In Alibaba Cloud, create a RAM account.
      Go to
      RAM > Users
      , and click
      Create User
      .
    2. Click
      Add Permissions
      .
    3. Search for
      registry
      , and then select
      AliyunContainerRegistryReadOnly
      .

    Scan images in Alibaba Cloud Container Registry

    To scan a repository in Alibaba Cloud Container Registry, create a new registry scan setting.
    Prerequisites:
    • You’ve installed a Container Defender somewhere in your environment.
    • You’ve already created an Alibaba Cloud Container Registry.
    • You have the service account credentials.
    1. Open Console, and go to 
      Defend > Vulnerabilities > Registry
      .

    2. Click
      Add registry
      .
    3. In the
      Add New Registry Setting Specification
       dialog, enter the following values:
      1. In the
        Version
         drop-down list, select 
        Docker Registry v2
        .
      2. In the
        Registry
         field, enter the Fully Qualified Domain Name (FQDN) for the registry. For example,
        registry-intl.cn-hangzhou.aliyuncs.com
        .
      3. In the
        Repository
         field, enter the name of the repository to scan. Example: 
        library/alpine
        .
      4. In the
        Tag
         field, enter an image tag. Leave this field blank to scan all images, regardless of their tag.
      5. In the
        Credential
         field, configure how Prisma Cloud authenticates with Alibaba Cloud Container Registry.
        Select a credential from the drop-down list. If there are no credentials in the list, click 
        Add new
        , and create a
        Basic authentication
         credential with the service account username and password.
      6. In the
        OS type
         field, specify whether the repo holds
        Linux
         or
        Windows
         images.
      7. In
        Scanners scope
        , specify the collections of defenders to use for the scan.
        Console selects the available Defenders from the scope to execute the scan job according to the
        Number of scanners
         setting. For more information, see deployment patterns.
      8. In
        Number of scanners
        , enter the number of Defenders across which scan jobs can be distributed.
      9. In
        Cap

        Set
        Cap
         to
        5
         to scan the five most recent images, or enter another value to increase or decrease the limit. Set
        Cap
         to
        0
