Warning!

Puhti and Mahti are being decommissioned in stages, and their storage areas will become fully unavailable from 15 October 2026. Clean up unnecessary files and move any data you need to keep by 31 August 2026. See the Roihu data migration guide for instructions on transferring your data to Roihu.

Puhti scratch is very full: keep only active data there and move or delete everything else. No new Puhti scratch quota will be granted.

Deployment Security

This section controls image verification and vulnerability enforcement.

Administrators can enforce security policies such as:

Allowing only signed images

Two image signature verification mechanisms are there, cosign and Notation. If enabled, only signed images can be deployed. It ensures image integrity and authenticity.

Preventing the use of vulnerable images

If 'Prevent vulnerable images from running' is enabled, Satama blocks deployment of images that contain vulnerabilities above a selected severity level.

You can adjust severity threshold from dropdown. If 'Low' vulnerability severity is selected, that means if any vulnerability (Low, Medium, High, Critical) exists, deployment can be blocked.
