Docker Kubernetes 1.18警告ImageGCFailed错误获取imageFs信息失败：无法在内存缓存中找到数据

我在Centos 7上带了我的Kubernetes 1.18。我们还使用定制的CIDR

kubectl apply-f“$（kubectl版本| base64 | tr-d'\n'）&env.IPALLOC_RANGE=IPALLOC

最初，Kubernetes运行正常，但当我们多次运行同一个pod进行测试时，Kubernetes每5秒就会重新启动一次

当我检查时

Kubectl获取事件

journalctl-u kubelet | grep-i垃圾

---

请告诉我如何解决此问题。

我得到了解决方案，似乎删除的docker图像没有正确清理。对此一无所知。但下面的解决方案对我有效

docker system prune
systemctl stop kubelet
systemctl stop docker
systemctl start docker
systemctl start kubelet
