Kuberntes master在OpenStack heat中未启动

Question

在过去的一周左右，我一直在尝试使用this guide在OpenStack中建立一个Kubernetes集群。在这个过程中，我遇到了一些问题，下面的问题-> kube-up.sh failes in OpenStack描述了其中一个问题

在发出./cluster/kube-up.sh脚本时，它尝试使用openstack stack create步骤(Log)启动集群。在这里，由于某些原因，kubernetes master不能正常出现，这就是安装失败的地方。我能够通过SSH连接到主节点，并在/var/log/cloud-init-output.log中找到了以下内容

进一步深入研究后，我在/var/ https://paste.ubuntu.com/23733430/ /messages文件->中找到了以下代码片段

所以我假设Docker守护进程没有启动。另外，我的etcd配置也有问题，因为flanneld服务也没有启动。下面是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

尽管它在非标准端口上运行。

我也在一个代理公司的网络里。任何关于如何进一步调试这方面的建议都将不胜感激。到目前为止，我已经走到了一个死胡同，关于如何继续进行这件事。在kubernetes闲置通道中询问也没有产生任何结果！

Answer 1

/usr/bin/flanneld -etcd-endpoints=

这一行是你麻烦的来源，假设你在发布输出之前没有省略它。在非标准端口上运行etcd会使您的情况变得更糟，但值得庆幸的是，我认为这两个问题的解决方案实际上是相同的。

我期望运行systemctl cat flanneld.service (您可能需要sudo，这取决于您的系统设置的严格性)来输出flanneld的统一systemd描述符，包括任何“插件”、重写等，如果我的理论是正确的，那么它们中的一个将是Environment=或EnvironmentFile=，我打赌flanneld.service期望在<代码>d12中有ETCD_ENDPOINTS=或FLANNELD_ETCD_ENDPOINTS= (作为seen here)可用。

因此，希望该文件要么丢失了，要么实际上是空白的，在这两种情况下，您都离教授flanneld关于您的etcd端点以及世界上的一切都很好只有一步之遥( vi )。
