类似的问题是由于CNI(印花棉布)引起的,但不确定ICP中的解决方法是什么(请参见下面的journalctl -u kubelet日志)

Kubectl(主节点):我认为此时应该已经初始化并运行了kube,但似乎还没有。
kubectl get pods -s 127.0.0.1:8888 --all-namespaces
The connection to the server 127.0.0.1:8888 was refused - did you specify the right host or port?
以下是我尝试过的选项:
ifconfig tunl0返回以下内容(即,不分配IP):
tunl0 链接封套:IPIP隧道HWaddr
NOARP MTU:1480 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000
RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)
“ calicoctl获取配置文件”返回空,“ calicoctl获取节点”也返回空,我相信是因为尚未配置calico。
其他检查,想法和选择?

答案 0 :(得分:1)
首先,从ICP 2.1.0.3起,禁用了K8S apiserver的不安全端口8888,因此您不能使用此不安全端口与Kubenetes通讯。
对于此问题,您能告诉我以下信息或输出吗?
答案 1 :(得分:0)
问题似乎与我使用的Docker存储驱动程序(btrfs)有关。切换到“覆盖”后,我就可以继续前进了。
答案 2 :(得分:0)
我有相同的经历,至少是相同的高级错误消息:
“失败-重试:等待kube-dns启动”。
我必须做两件事才能通过此安装步骤:
完成后,安装完成。
