I'm trying to Use an Image Volume With a Pod, but having no luck. Wondering if someone has ever gotten it working?
My Setup:
bash-3.2$ minikube version
minikube version: v1.34.0
commit: 210b148df93a80eb872ecbeb7e35281b3c582c61
bash-3.2$ kubectl version
Client Version: v1.31.1
Kustomize Version: v5.4.2
Server Version: v1.31.0
I start Minikube with minikube start --feature-gates=ImageVolume=true
and confirm that ImageVolume feature is enabled:
bash-3.2$ kubectl get --raw /metrics | grep kubernetes_feature_enabled | grep -i imagevolume
kubernetes_feature_enabled{name="ImageVolume",stage="ALPHA"} 1
I tried to follow the example at Use an Image Volume With a Pod but step 1 (create the pod on your cluster fails):
bash-3.2$ kubectl apply -f https://k8s.io/examples/pods/image-volumes.yaml
pod/image-volume created
bash-3.2$ k get pods
NAME READY STATUS RESTARTS AGE
image-volume 0/1 ErrImagePull 0 7s
bash-3.2$ k describe pods image-volume
results in this error: Failed to pull image "quay.io/crio/artifact:v1": invalid rootfs in image configuration
I changed spec.volumes.image.reference to just use debian and then
bash-3.2$ k describe pods image-volume
results in Successfully pulled image "debian" in 607ms (607ms including waiting). Image size: 138845227 bytes. (yay!!)
but also Error: Error response from daemon: invalid volume specification: ':/volume'
I've tried with my own images and I always get the error invalid volume specification
I also tried to follow this Medium article - Kubernetes Image Volumes: A deep dive, but this seems to be doing things incorrectly since spec.volumes.imageVolume is wrong:
Pod in version "v1" cannot be handled as a Pod: strict decoding error: unknown field "spec.volumes[0].imageVolume"
I understand that ImageVolume is a new feature. But I hope someone has gotten it working. If so, can you please share a working example. Or help me figure out what's going wrong in my attempts?
Thanks!
