For users​

Using the Quay plugin in Backstage​

Quay is a front-end plugin that enables you to view the information about the container images.

Prerequisites​

• Your Backstage application is installed and running.
• You have installed the Quay plugin. For installation process, see Installation.

Procedure​

1. Open your Backstage application and select a component from the Catalog page.

2. Go to the Image Registry tab.

   The Image Registry tab in the Backstage UI contains a list of container images and related information, such as TAG, LAST MODIFIED, SECURITY SCAN, SIZE, EXPIRES, and MANIFEST.

   

3. If a container image does not pass the security scan, select the security scan value of the image to check the vulnerabilities.

   

   The vulnerabilities page displays the associated advisory with a link, severity, package name, and current and fixed versions.

   

   The advisory link redirects to the Red Hat Security Advisory page that contains detailed information about the advisory, including the solution.
