Warning!

Puhti and Mahti will be decommissioned after Roihu becomes available. Users should clean up unnecessary files and move any required data by the end of August 2026. See the Roihu data preparation instructions for details.

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

Using the web interface

All applications launched in OpenShift run within projects that can be created by any authenticated user. Each project has its own private virtual network and it is isolated from other projects. Users can only see projects they have created themselves or that have been shared with them. Any containers, volumes and other resources created by users are always created within a project. You might need to wait a few hours after your access application is accepted, before you can authenticate to Rahti.

You can either select applications to run from Ecosystem -> Software Catalog after creating a project or launch any applications using the primitives described in the background chapter.
