上周左右，我一直在尝试使用本指南在OpenStack中设置一个Kubernetes集群。我在这个过程中遇到了一些问题，其中一个问题在这个问题中描述了->kube-up.sh在OpenStack 中失败
在发出./cluster/kube-up.sh脚本时，它会尝试使用openstack堆栈创建步骤(Log)来启动集群。在这里，由于某种原因，kubernetes master没有正确出现，这里是安装失败的地方。我能够SSH到主节点，并在/var/log/cloud-init-output.log中发现了这一点

在进一步挖掘时，我在/var/log/messages文件->中发现了这个片段https://paste.ubuntu.com/23733430/
所以我假设Docker守护进程没有启动。此外，我的etcd配置也出现了问题，因此法兰绒服务也没有启动。这是service flanneld status的输出

我的etcd守护进程正在运行：
[root@kubernetesstack-master salt]# netstat -tanlp | grep etcd
tcp 0 0 192.168.173.3:4379 0.0.0.0:* LISTEN 20338/etcd
tcp 0 0 192.168.173.3:4380 0.0.0.0:* LISTEN 20338/etcd
尽管它在非标准端口上运行。
我也在一个代理下的公司网络中。任何关于如何进一步调试的建议都将受到赞赏。到目前为止，我对如何进行这项工作已经走到了死胡同。在kubernetes松弛的渠道询问也产生了零结果！
/usr/bin/flanneld -etcd-endpoints=
假设你在发布输出之前没有删除输出，那么这一行就是你的麻烦来源。在非标准端口上运行etcd会让你的情况变得更糟，但谢天谢地，我认为这两个问题的解决方案实际上是相同的。
我希望运行systemctl cat flanneld.service(根据系统设置的严格程度，您可能需要sudo)来输出flanneld的统一系统描述符，包括任何"插入"、覆盖等。如果我的理论正确，其中一个将是Environment=或EnvironmentFile=，这就是我打赌flanneld.service希望ETCD_ENDPOINTS=或FLANNELD_ETCD_ENDPOINTS=(如图所示)可用于Exec的地方。
因此，希望该文件要么缺失，要么实际上是空白的，在任何一种情况下，你都只需要一个快速的vi，就可以教法兰绒关于你的etcd端点的知识，让世界上的一切都恢复正常。
