We are using mentioned image for our NFS caching of firmware to reduce the costs.
Unfortunately something happened with that image and it ceased to exist, which caused our NFS server to fail and
consequently computing clusters stopped to compile kernels.
Temporary i found alternative image, but it is not ideal, because it is not updated and it is not ours: docker.io/adnanhodzic/nfs-server-k8s
I will update the image in all clusters to the new one, but we need to find a long term solution for this, either by maintaining our own image or by finding a reliable one.
At the moment of writing work still on progress.
