Hazelcast in Docker in boot2docker“获取集群分区表时出错”

Question

我的设置：Hazelcast docker container 在 boot2docker vm 中运行（托管在 Windows 上，是的，端口 5701 被转发）。 那是 Hazelcast 3.4.2。

当我尝试将一个简单的 java 客户端连接到这个 hazelcast 实例时，我得到一个：

总结一下：客户端似乎看到了集群及其成员，但接下来发生的事情阻止了连接按预期工作。

有什么想法吗？

我猜你的问题是，Hazelcast 节点的内部地址和外部地址不同，即使由于 NAT 可以到达该节点，该节点也拒绝接受公共地址上的请求。 您可以使用以下配置配置公共地址：http://docs.hazelcast.org/docs/3.4/manual/html-single/hazelcast-documentation.html#public-address（参见上面的示例）。
