Hi我已经部署了3个节点的kubernetes集群(一个主节点，两个工作节点(，如下所示：
kubectl get nodes
NAME STATUS ROLES AGE VERSION
master.domain.com Ready control-plane 161m v1.24.4
worker1.domain.com Ready <none> 154m v1.24.4
worker2.domain.com Ready <none> 153m v1.24.4
我使用了cri-o容器运行时，尝试创建一些pod，但由于以下事件而失败：
Events:
Type Reason Age From Message
---- ------ ---- ---- -------
Normal Scheduled 40s default-scheduler Successfully assigned default/nginx to worker2.domain.com
Normal BackOff 26s kubelet Back-off pulling image "nginx"
Warning Failed 26s kubelet Error: ImagePullBackOff
Normal Pulling 11s (x2 over 32s) kubelet Pulling image "nginx"
Warning Failed 2s (x2 over 27s) kubelet Failed to pull image "nginx": rpc error: code = Unknown desc = Error reading manifest latest in registry.hub.docker.com/nginx: unauthorized: authentication required
Warning Failed 2s (x2 over 27s) kubelet Error: ErrImagePull
吊舱定义文件如下：
apiVersion: v1
kind: Pod
metadata:
name: nginx
labels:
app: frontend
spec:
containers:
- name: nginx
image: nginx
和我用mysql而不是nginx尝试的一样，我在mysql pod中得到了下面的事件，看起来它可以提取图像，但不能运行pod：
Type Reason Age From Message
---- ------ ---- ---- -------

以下是POD状态：
NAME READY STATUS RESTARTS AGE
mysql 0/1 CrashLoopBackOff 8 (4m51s ago) 23m
nginx 0/1 ImagePullBackOff 0 3m26s
您实际上不需要任何额外的配置就可以从公共映像注册表中提取映像
容器/映像库用于从注册表中提取映像。目前，它支持Docker模式
2/version 1和模式2/version 2。它还通过了所有Docker和Kubernetes测试。
cri容器图像
因此，只要提到具有正确URI的图像，它就会起作用。
