我一直在尝试使用this guide在OpenStack的最后一周左右设置一个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有所描述 - > kube-up.sh failes in OpenStack
在发出./cluster/kube-up.sh
脚本时,它会尝试使用openstack stack create步骤(Log)启动集群。在这里,出于某种原因,kubernetes master无法正常启动,这里安装失败。我能够通过SSH进入主节点并在/var/log/cloud-init-output.log

所以我假设Docker守护进程没有启动。还有一些事情搞砸了我的etcd配置,因为flanneld服务也没有启动。这是service flanneld status

我的etcd守护程序正在运行:
[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
虽然它在非标准端口上运行。
我也在代理下的公司网络中。任何有关如何进一步调试这一点的指示表示赞赏。到目前为止,我已经达成了如何处理这个问题的死胡同。询问kubernetes松弛的渠道也产生了零结果!
答案 0 :(得分:0)
/usr/bin/flanneld -etcd-endpoints=
假设您在发布之前没有删除输出,那么该行就是您的麻烦的来源。在非标准端口上运行的etcd使你的情况变得更糟,但幸运的是我认为两者的解决方案实际上都是同样的解决方案。
我希望运行systemctl cat flanneld.service
(您可能需要sudo
,具体取决于系统设置的严格程度)输出flanneld
的统一systemd描述符,包括任何“drop-ins” “,覆盖等,如果我的理论是正确的,其中一个将是Environment=
或EnvironmentFile=
,这就是我打赌flanneld.service
期望有ETCD_ENDPOINTS=
或FLANNELD_ETCD_ENDPOINTS=
可以使用Exec
(seen here}。
所以希望这个文件丢失或者实际上是空白的,在任何一种情况下,你都可以快速vi
教授关于你的etcd端点的flanneld,并且世界上的一切都很好。
