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.

Why this container report permission denied errors?

The most common reason for a container to fail to run in Rahti, is that the container image expects to be run as root. As Rahti does not run images as root, permission denied errors will stop the execution.

The solution is to use a different image. The first option is to find another image that is prepared to be run as a non root user. If there is not an image already prepared to run in OpenShift, or it is not provided by a trustable source, the other option is to modify the current image to make it work with a non root user, for example as described in the Creating images section.
