- kubectl get pods -A -o wide
- 查看日志发现
-
pods "kube-flannel-ds-amd64-xxxxx" is forbidden: User "system:serviceaccount:kube-system:flannel" cannot get resource "pods" in API group "" in the namespace "kube-system"
-
也就是说flannel用户不能访问kube-system空间下的pods资源
-
但kube-flannel空间下的pod都正常，说明这个集群角色绑定需要再把kube-system空间再绑一下即可
-
kubectl describe clusterrolebinding -A
kubectl get clusterrole -A |grep flannel
flannel
kubectl describe clusterrole flannel

查到有一个clusterrole=flannel 集群角色，直接给他们绑定即可
- kubectl create clusterrolebinding add-on-flannel
- --clusterrole=flannel
- --serviceaccount=kube-system:flannel
kubectl describe clusterrolebinding -A
-
#新添加的clusterrolebinding将flannel用户绑定到了kube-system空间，解决上面的异常

三个节点上的kube-flannel-ds-amd64-xxxxx容器过会都自动启动了
