刚开始接触 kubernetes。我有三台物理机：1台master，2台节点。我基本上做了入门配置。一切似乎都已启动并正在运行，节点可以与主节点通信，但是当我尝试安装示例应用程序（请参阅以下 kubernetes 指南）时，我一遍又一遍地收到此警告：

kubelet does not have ClusterDNS IP configured and cannot create Pod using "ClusterFirst" policy. Falling back to DNSDefault policy.

我无法访问该应用程序：master_ip:30001

知道发生了什么以及如何解决它吗？

配置

这是配置：

$ kubectl get nodes

NAME                     STATUS    AGE       VERSION
master-precision-t1600   Ready     19h       v1.7.4
node2-precision-t1600    Ready     19h       v1.7.4

$ kubectl get pods --all-namespaces

NAMESPACE     NAME                                             READY     STATUS    RESTARTS   AGE
kube-system   etcd-master-precision-t1600                      1/1       Running   1          19h
kube-system   kube-apiserver-master-precision-t1600            1/1       Running   1          19h
kube-system   kube-controller-manager-master-precision-t1600   1/1       Running   1          19h
kube-system   kube-dns-2425271678-xrlp4                        3/3       Running   3          19h …

我有以下代码:

byte[] S = new byte[256];
byte[] T = new byte[256];

for (int i = 0; i < 256; ++i) {
    S[i] = (byte)i;
    T[i] = 13;
}

int j = 0;
int i2 = 0;
while (i2 < 256) {
    j = j + S[i2] + T[i2] & 255;
    byte[] arrby = S;
    int n2 = i2;
    arrby[n2] = (byte)(arrby[n2] ^ S[j]);
    byte[] arrby2 = S;
    int n3 = j;
    arrby2[n3] = (byte)(arrby2[n3] ^ S[i2]);
    byte[] arrby3 = S; …
