由未知权威机构签署的x509证书 - Kubernetes-Java 学习之路

我正在配置kubernetes集群，在coreos中有2个节点，如https://coreos.com/kubernetes/docs/latest/getting-started.html所述，没有 flannel . 两台服务器都在同一网络中 .

But I am getting: x509: certificate signed by unknown authority (possibly because of "crypto/rsa: verification error" while trying to verify candidate authority certificate "kube-ca") 在 Worker 中运行kubelet时 .

我在文档中讨论了在两台服务器上正确配置TLS cerficates .

主节点工作正常 . 而kubectl能够在主人身上解雇容器和 beans 荚 .

问题1：何解决这个问题？

问题2：有没有办法在没有TLS证书的情况下配置集群 .

VERSION_ID=899.15.0
BUILD_ID=2016-04-05-1035

Etcd conf：

$ etcdctl member list

那么回答你的第一个问题，我认为你必须做一些事情来解决你的问题 . 首先运行此链接中给出的命令（kubernetes.io/docs/setup/independent/create-cluster-kubeadm / ...）然后几个命令： 1）mkdir -p $ HOME / .kube 2）sudo cp -i /etc/kubernetes/admin.conf $ HOME / .kube / config 3）sudo chown $（id -u）：$（id -g）$ HOME /.kube/config . 这个admin.conf应该为kubectl所知，以便正常工作 .

请将此视为参考，并可能通过导出您的证书来帮助您解决问题：
```
kops export kubecfg "your cluster-name"
export KOPS_STATE_STORE=s3://"paste your S3 store"
```
希望有所帮助 .
