Trying and failing to pull image (maria-db) on Raspberry Pi 3B+

I get the following error when I execute "kubectl logs nextcloud-team-nextcloud-db-75f7cd8c8f-qs2ng":

Error from server (BadRequest): container "nextcloud-team-nextcloud-db" in pod "nextcloud-team-nextcloud-db-75f7cd8c8f-qs2ng" is waiting to start: trying and failing to pull image.

The command "kubectl describe pods nextcloud-team-nextcloud-db-75f7cd8c8f-qs2ng" shows:

Normal BackOff 4m16s (x337 over 84m) kubelet, raspberrypi Back-off pulling image "mariadb"

I use Raspbian as an Operation System.

Start by reproducing the deployment on the Raspberry Pi 3B+ and inspect the pod with the kubectl logs and kubectl describe commands included in the issue. Check the reported image-pull events and determine what change is needed for the MariaDB container to start; done means the pod pulls its image and reaches a running state.
