如何将Vagrant计算机连接到在OpenStack集群中运行的Consul服务器？

我在OpenStack集群中有2个实例。一个作为Consul服务器（agent-one）运行，另一个作为客户端（agent-two）运行。他们加入并报告通过健康检查。

在我的本地机器上，我在本地计算机上启动了一个Vagrant（vagrant-one）并希望加入OpenStack的领事方。

此时，领事登录流浪者 - 读取：

2014/09/26 18:02:42 [INFO] serf: EventMemberJoin: vagrant-one 10.0.2.15
2014/09/26 18:02:42 [ERR] agent: failed to sync remote state: No known Consul servers

我跑了consul join <consul-server-hostname>并报告：

Successfully joined cluster by contacting 1 nodes.

然后日志报告了vagrant-one上的以下事件序列：

2014/09/26 18:07:22 [INFO] agent.rpc: Accepted client: 127.0.0.1:39070
2014/09/26 18:07:22 [INFO] agent: (LAN) joining: [consul-server-hostname]

2014/09/26 18:07:57 [ERR] agent: failed to sync remote state: No known Consul servers

所以看起来它最初可以连接。它获取在OpenStack集群中运行的两个consul代理的节点名称。 OpenStack集群中的节点上的健康检查都没有通过，并且流氓 - 最终还原为＆＃34;没有已知的Consul服务器＆＃34;。

如果我向OpenStack Consul代理添加-advertise <associated-ip>标志，那么vagrant-one似乎能够接收代理二的健康检查，但由于某种原因而不是代理一。虽然此时此问题似乎是一个网络问题。

您的Vagrant框在Virtualbox（或VMWare）的虚拟NAT上运行。 Openstack群集中的节点暴露给LAN，但Vagrant盒子不是。最简单的解决方法是将您的Vagrant盒暴露给外部网络。将以下内容添加到您的Vagrant文件中。

config.vm.network "public_network"

将Vagrant连接到OpenStack中的Consul服务器
