在 kubernetes 中回退拉取镜像指标

如何解决在 kubernetes 中回退拉取镜像指标

我安装了 k8s 仪表板，如下为 github 仪表板地址。

kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.2.0/aio/deploy/recommended.yaml

和

的输出

kubectl get pods --all-namespaces

kubernetes-dashboard   dashboard-metrics-scraper-79c5968bdc-64wl9   0/1     ImagePullBackOff   0          48m
kubernetes-dashboard   kubernetes-dashboard-9f9799597-w9cp9         1/1     Running            0          48m

kubectl describe pod 的输出是
