我正在尝试在ubutnu上安装kubernetes (裸机安装)。我安装了一个主节点和一个节点,它看起来很好。我安装了ui插件,没有问题,但当我尝试安装dns插件时,pod不断地重新启动。
在kube-apiserver日志中,我得到:

我正在使用: ubuntu 14.04 kubernetes 1.1.2 add我尝试从kubernetes 1.1.2的addon目录创建dns插件

在更新api服务器的证书和密钥后,我也遇到了同样的问题。我在删除密钥后修复了DNS服务:
# Search the secret name
kubectl get pod --namespace=kube-system -l k8s-app=kube-dns -o yaml | grep -A1 serviceaccount
# Delete the current secret
kubectl delete secret/<name-of-the-secret> --namespace=kube-system我还需要重新启动整个POD,不知道是否有更好的方法:
kubectl delete svc/kube-dns rc/kube-dns-v9 --namespace=kube-system
kubectl create -f dns-addon.yaml 发布于 2016-01-23 02:41:02
我发现这不是skydns的问题,而是Kubernetes本身的问题。如果我将这个rc/service放在任何不同的名称空间中,它就能完美地工作。我在1.1.4 Kubernetes中遇到了这个问题
