The Issue

Someone has deleted the Cloud-Provider-vSphere project in the gcr.io registry for container images. The default pull policy for the vSphere CSI when using VMware’s manifests is set to always, meaning that if you reboot your cluster, it will not come back online.

This is what my cluster looked like when I booted it up today;

❯ kubectl get pods -n vmware-system-csi
NAME READY STATUS RESTARTS AGE
vsphere-csi-controller-776fb75cd8-ptw4s 5/7 ErrImagePull 0 84m

vsphere-csi-node-ww2zx 2/3 ImagePullBackOff 89 (3m5s ago) 143d

And when describing the pod;

❯ kubectl describe pod -n vmware-system-csi vsphere-csi-controller-776fb75cd8-ptw4s

The Cause

Who knows? Maybe it cost Broadcom too much to host the images in Google Cloud. Or maybe they are moving to a model where you can only access the files when you pay for VCF.

The Workaround

Luckily the images are mirrored by Rancher, so I just updated the vSphere CSI manifest from:

– https://raw.githubusercontent.com/kubernetes-sigs/vsphere-csi-driver/v3.3.1/manifests/vanilla/vsphere-csi-driver.yaml

And updated the image locations, you can get the updated file from my GitHub Gist belo.
