通过了CSR认证，却没有获取到nodes的信息

[root@k8s-01 ssl]# kubectl get csr NAME AGE REQUESTOR CONDITION csr-b0gpz 6m kubelet-bootstrap Pending csr-swnf0 27m kubelet-bootstrap Pending [root@k8s-01 ssl]# kubectl certificate approve csr-b0gpz csr-swnf0 certificatesigningrequest "csr-b0gpz" approved certificatesigningrequest "csr-swnf0" approved [root@k8s-01 ssl]# kubectl get nodes No resources found. [root@k8s-01 ssl]#

看看 kubelet 的日志有没有 Error、Warning 类的信息。

同样的问题，我是kubelet节点重做系统了，但之前已经执行kubectl delete node了

kubelet log

I1201 22:54:13.154470   12258 bootstrap.go:58] Using bootstrap kubeconfig to generate TLS client cert, key and kubeconfig file
I1201 22:54:13.182429   12258 csr.go:96] csr for this node already exists, reusing
I1201 22:54:13.184398   12258 csr.go:104] csr for this node is still valid

新的csr没有Issued字段

kubectl get csr
NAME                                                   AGE       REQUESTOR           CONDITION

换了一个apiserver后莫名好了，详细待查

zhangbei59 commented 6 years ago

解决了吗？

lijunyong commented 6 years ago

@okletswin 我也遇到了，你怎么解决的？

SchoIsles commented 6 years ago

@lijunyong 集群里有3个apiserver，在写kubeconfig时填了其它实例的地址，就好了。。。

MikelPan commented 6 years ago

我今天也遇到了这个问题，不知道怎么解决

通过了CSR认证，却没有获取到nodes的信息

[root@k8s-01 ssl]# kubectl get csr NAME AGE REQUESTOR CONDITION csr-b0gpz 6m kubelet-bootstrap Pending csr-swnf0 27m kubelet-bootstrap Pending [root@k8s-01 ssl]# kubectl certificate approve csr-b0gpz csr-swnf0 certificatesigningrequest "csr-b0gpz" approved certificatesigningrequest "csr-swnf0" approved [root@k8s-01 ssl]# kubectl get nodes No resources found. [root@k8s-01 ssl]#

有approved 但没有issued，是因为申请通过认证但是没有正常颁发证书。查看一下kube-controller-manager的日志是不是报错了

查看kube-controller-manager是否报错，我的是这个问题
