What changes shall I made in order to fix this?为了解决这个问题,我应该做哪些更改?
Use flannel yaml from the official documentation使用官方文档中的flannel yaml
kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/2140ac876ef134e0ed5af15c65e414cf26827915/Documentation/kube-flannel.yml

serviceaccount/flannel unchanged
configmap/kube-flannel-cfg configured

As @suren correctly mention - the issue is in the apiVersion: extensions/v1beta1
正如@suren 正确提到的那样 - 问题出在
apiVersion: extensions/v1beta1
In latest yaml it looks like在最新的 yaml 中,它看起来像
---
apiVersion: apps/v1
kind: DaemonSet
metadata:
name: kube-flannel-ds-amd64
namespace: kube-system
labels:
tier: node
app: flannel
spec:
selector:
matchLabels:
app: flannel
template:
metadata:
labels:
tier: node
app: flannel
...
That's a versioning issue with the DaemonSet and your kubernetes cluster.这是 DaemonSet 和您的 kubernetes 集群的版本控制问题。 You are using
extensions/v1beta1
, but DaemonSets
have been promoted to apps/v1
.您正在使用
extensions/v1beta1
,但DaemonSets
已升级为apps/v1
。
If you already have api-server
running, try kubectl explain daemonset
, and it will tell you what should be the apiVersion
for the DaemonSets
.如果您已经运行了
api-server
,请尝试kubectl explain daemonset
,它会告诉您apiVersion
的DaemonSets
应该是什么。
If not, just download the flannel file, edit it, change the apiVersion: extensions/v1beta1
, by apiVersion: apps/v1
, and it should work.如果没有,只需下载法兰绒文件,编辑它,更改
apiVersion: extensions/v1beta1
,通过apiVersion: apps/v1
,它应该可以工作。
