每次在Ubuntu 16.04中kubeadm join命令都会超时 [英] kubeadm join command gets timed out every time in Ubuntu 16.04

问题描述

我正在使用Ubuntu 16.04(Xenial)，但是在将nodes联接到我的master时，我遇到了kubeadm的问题:

I am using Ubuntu 16.04 (Xenial) but here's a problem which I face with kubeadm while joinig nodes to my master:

将node加入我的master时，我不断遇到超时问题-

While joining a node to my master, I continuouly get a timeout issue -

[discovery] Failed to request cluster info, will try again: [Get 
https://{{MASTER_IP}}/api/v1/namespaces/kube- 
public/configmaps/cluster-info: dial tcp {{MASTER_IP}}: i/o timeout]
[discovery] Failed to request cluster info, will try again: [Get 
https://{{MASTER_IP}}/api/v1/namespaces/kube- 
public/configmaps/cluster-info: dial tcp {{MASTER_IP}}: i/o timeout]

注意:我故意将我的IP地址更改为{{MASTER_IP}}，但这只是主服务器的IP地址.

我可以从node ping master.我什至可以加入ssh，但是不能将其加入集群.我还必须提到，我不是在代理后面进行操作(我稍后添加了此内容)

I can ping the master from my node. I can even ssh into it but I can't join it to the cluster. I must also mention that I am not operating behind a proxy (I added this later)

我尝试过使用no_proxy={{MASTER_IP}}这样的标志.我还尝试使用命令

I have tried with flags like no_proxy={{MASTER_IP}} . I have also tried initiating the cluster on the master with the command

sudo kubeadm init --apiserver-advertise-address={{MASTER_IP}}

我可能在哪里出错?请帮助大家！！

P.S. -我已经解决了与此相关的git问题.我曾尝试过他们的解决方案，但徒劳无功.这是其中一个的链接- https://github.com/kubernetes/kubernetes/issues/58921

推荐答案

禁用防火墙对我有用.我可以使用kubeadm join将Node机器连接到master机器.

Disabling the firewall worked for me. I was able to connect my Node machine to the master machine using kubeadm join.
