Cleanup Setting

This section explains how to configure Aqua server to remove selected artifacts of a certain age. To configure the Cleanup settings, you should navigate to Settings > Cleanup. You can configure the following settings in this page:

  • Remove old images from repositories automatically
  • Remove old audit events automatically


Remove old images automatically

You can configure Aqua server to remove the oldest images automatically from the repositories configured in Aqua. This has two benefits: 

  • Force users to use more recent images
  • Improve the performance of Aqua scanners by reducing the number of images to be scanned
  • Control the number of images stored in each repository before it reaches the limit set for Advanced or Team tier customers
Limitations on the repositories and images stored in Aqua for scanning:

- If you use Aqua Advanced plan, you can add a maximum of 100 repositories and unlimited images in each repository.

- If you use Aqua Team plan, you can add a maximum of 40 repositories and 10 images in each repository.

In both the Team and Advanced plans, Adding each repository consumes 250 Aqua units from your account.


When the old images are removed automatically from Aqua, the actual images are not deleted, either from the registry or from the host on which they are located. You can configure the maximum number of images to store in your repositories (other than the limit set for your Aqua edition). You can also set the criterion for determining the age of each image since: 

  • created time in registry
  • recent scan date
  • it was registered in the Aqua server


If adding an image to a repository exceeds the threshold set, Aqua removes the oldest image automatically, according to the selected criterion, from the repository. This applies to all methods of adding the images: through Images page > Add Image, new images pulled from registries regularly, or new images added through scanner Command Line Interface (CLI).


To configure this Cleanup setting:

  1. Enable the Remove the oldest images in each repository checkbox.
  2. Set the time of the day for the image cleanup to occur. 
  3. Select either Daily or Specific Days of the week for the image cleanup to occur at the specified time of the day.
  4. Set the maximum number of images allowed to store in each repository. (50 number set in the example)
  5. From the dropdown, select one of the following criteria to calculate age of the image:
  • Time of Creation in Registry
  • Last Scan Date
  • Time of Image Registration

      6. Click Save


In the example shown below, Aqua removes oldest images at 12:00 am every Wednesday, Friday, and Sunday when total number of images exceeds 50 in any repository. In this example, age of the images is calculated from the time of image registration in Aqua server.


Cleanup settings are applied to all repositories on the Aqua server.
