无法连接到Docker内部的Coherence集群
我已经在两个容器中创build了一个简单的Coherence（3.7）集群。 一个容器有一个caching节点，另一个容器有一个代理节点。 两个容器都以网桥模式启动，我可以从日志文件中正确地看到它们形成一个集群：
MasterMemberSet( ThisMember=Member(Id=2, Timestamp=2017-11-14 14:13:50.376, Address=172.17.0.2:9155, MachineId=22297, Location=site:,rack:4500a,machine:f0ace732de72,process:23,member:proxy, Role=sandbox_proxy) OldestMember=Member(Id=1, Timestamp=2017-11-14 14:13:19.81, Address=172.17.0.3:8150, MachineId=20222, Location=site:,rack:4500a,machine:40e89ba7487c,process:24,member:storage, Role=sandbox_cache) ActualMemberSet=MemberSet(Size=2 Member(Id=1, Timestamp=2017-11-14 14:13:19.81, Address=172.17.0.3:8150, MachineId=20222, Location=site:,rack:4500a,machine:40e89ba7487c,process:24,member:storage, Role=sandbox_cache) Member(Id=2, Timestamp=2017-11-14 14:13:50.376, Address=172.17.0.2:9155, MachineId=22297, Location=site:,rack:4500a,machine:f0ace732de72,process:23,member:proxy, Role=sandbox_proxy) ) MemberId|ServiceVersion|ServiceJoined|MemberState 1|3.7.1|2017-11-14 14:13:19.81|JOINED, 2|3.7.1|2017-11-14 14:13:50.738|JOINED 我有caching节点的WKA端口映射到主机，以及代理节点的代理端口：
40e89ba7487c coh_storage "/usr/local/cohere..." About an hour ago Up About an hour 0.0.0.0:8150->8150/tcp, 0.0.0.0:8151->8151/udp coh-storage f0ace732de72 coh_proxy "/usr/local/cohere..." About an hour ago Up About an hour 0.0.0.0:10099->10099/tcp coh-proxy
注意：存储节点映射8151 / udp的原因是因为我们启用了自动增量选项，我发现存储节点在容器内正在监听端口。
我可以看到主机上可用的端口，可以telnet到他们，所以我不认为这个问题是networking相关的：
> netstat -an | grep 8150 tcp6 0 0 ::1.8150 *.* LISTEN tcp4 0 0 *.8150 *.* LISTEN > telnet 127.0.0.1 8150 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'.
问题是我们有2个应用程序，1个连接到存储节点，1个连接到代理节点（通过Coherence Extend）。 后者完美的工作，但前者不。 应用程序无法连接到存储节点，而是尝试形成自己的群集：

这是应用程序用于连接到caching节点的tangosol覆盖文件：
