Question

我在CoreOS上真的很新，我尝试使用official doc创建一个包含Vagrant的3个节点的群集。但是，当我访问其中一个节点并执行命令：fleetctl list-machines时，输出显示一些错误：

E0729 09:29:05.725714 01013 fleetctl.go:141] error attempting to check latest fleet version in Registry: 501: All the given peers are not reachable (Tried to connect to each peer twice and failed) [0]
Error retrieving list of active machines: 501: All the given peers are not reachable (Tried to connect to each peer twice and failed) [0]

我可以通过代理访问互联网 - ＆gt; 172.23.1.0:3128

我怀疑发生了错误，因为无法连接节点 https://discovery.etcd.io/2bef6823259cdef6751632f1f7052ff3 但是我不确定问题是什么，我做的是不知道如何解决它。

我正在使用：

Vagrant -----＆gt; 1.6.3

VirtualBox - ＆gt; 4.3.10_Ubuntu

CoreOS包装盒 - ＆gt; 367.1.0（稳定）

这些是我的资源文件：

Answer 1

最后，我从github repo下载 etcd ，然后在IP地址为10.10.10.10的永久主机上运行 etcd 。然后，受到运行your own discovery endpoint的CoreOS指令的启发，我在 user-data：中设置了发现地址，如下所示：

discovery: http://10.10.10.10:4001/v2/keys/2bef6823259cdef6751632f1f7052ff3

在此之后，我可以执行vagrant up，当我检查http://10.10.10.10:4001/v2/keys/2bef6823259cdef6751632f1f7052ff3时，所有CoreOS实例都已注册。

Answer 2

我为etd打开an issue以通过env vars支持代理，类似于CoreOS update_engine。

要在短期内解决此问题，您可以通过cli flag或配置文件对机器的对等地址列表进行硬编码。 --peers或--peers-file可能是您最好的选择。

Answer 3

我遇到了同样的问题。就我而言，它是由＃cloud-config中的陈旧发现URL引起的。我通过从https://discovery.etcd.io/new

获取新的发现网址来修复它
