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.

Tag Retention Policy

Container registries can accumulate many image versions over time. Tag retention policies help automatically remove unused or old image tags to save storage space.

Instead of manually deleting images, administrators can define rules that determine which tags should be kept and which should be removed.

How to Configure Tag Retention

To configure tag retention, open the Project in Satama and go to Policy tab.

Policy tab

Click on Tag Retention section. Click on Add rule. A pop-up window will open

Add tag Retention

Create a rule specifying which images should be retained and which should be deleted.

For example, * Keep the latest 10 tags * Delete tags older than 30 days * Keep tags matching release- pattern*

Once configured, Satama will automatically apply the policy according to the defined schedule.
