Help Needed on Running Image Volume Feature #8499
-
|
I'd like to try the image volume feature in Kubernetes v1.31 (https://kubernetes.io/docs/tasks/configure-pod-container/image-volumes/), so I rebuilt a Minikube Docker image to update CRI-O to v1.30.4. My Minikube start command is as follows: minikube stop
minikube delete
minikube image load kicbase:crio-v1.30.4
minikube start --container-runtime=cri-o --kubernetes-version=v1.31.0 --feature-gates=ImageVolume=true --base-image="kicbase:crio-v1.30.4"Everything seemed fine, but after applying a YAML file for a pod with an OCI image volume, the pod failed to start with the following error: ---
apiVersion: v1
kind: Pod
metadata:
name: pod
spec:
containers:
- name: test
image: ubuntu:22.04
command: ["sleep", "infinity"]
imagePullPolicy: IfNotPresent
volumeMounts:
- name: oci-volume
mountPath: /volume
volumes:
- name: oci-volume
image:
reference: ubuntu:20.04
pullPolicy: IfNotPresentI double-checked all the versions, and everything looks good: ➜ OCIVolume docker exec -it minikube bash
root@minikube:/# crio --version
crio version 1.30.4
Version: 1.30.4
