由于docker-machine使用的vboxnet，Hazelcast多播不起作用

在我的macOs上安装dockerForMac和virtualbox之后，本地hazelcast成员不能使用hazelcast的多播configuration（不在容器中）看到对方。 看来他们俩都是不同港口的集群中的主人。 docker等东西安装后的差异是成员的IP地址。 这是我的本地IP地址，但现在它有192.168.99.1被vboxnet使用。 看我的ifconfig。 这个注释是关于多播发现function的端口使用的：看起来Hazelcast在UDP端口54327（默认情况下）使用多播地址224.2.2.3进行发现，然后使用端口5701进行TCP通信。 打开防火墙中的UDP端口54327为我解决了发现问题。 （我也打开了TCP端口5701，但这还不够。） 反正有榛树使用我的IP地址？ 或者有无论如何打开vnetbox这些端口？ 使用ifconfig： vboxnet0: flags=8842<BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 ether XX:XX:XX:00:00:00 vboxnet1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 ether XX:XX:XX:00:00:01 inet 192.168.99.1 netmask 0xffffff00 broadcast 192.168.99.255 节点1： 2017-09-21 12:52:20.882 DEBUG 74783 — [ main] chicluster.impl.MulticastJoiner : [192.168.99.1]:5701 [OSMAN] [3.8.4] PostJoin master: [192.168.99.1]:5701, isMaster: true 2017-09-21 12:52:20.882 INFO 74783 — [ main] chicluster.impl.MulticastJoiner […]

无法将远程Hazelcast客户端连接到在Docker容器中运行的群集

我有一个运行在Docker容器中的Hazelcast集群，使用动物园pipe理员的发现API。 这一切都正常工作，并启动群集，并按预期工作。 我的问题是连接客户端从另一台服务器的集群。 群集正在将127.0.0.1和172.17.0.1返回给zookeeper，因为它是群集地址，这意味着客户端可以在同一台机器上正常运行，但即使将172.17.0.1映射到客户端主机文件中，也不会从远程计算机连接到Hz集群的服务器ip。 我试着用net = host和-h启动容器，让它返回一个地址，我可以在客户端的主机文件中映射，但似乎没有任何工作。 我错过了什么吗？

在具有TCPIP的多节点docker环境中进行Hazelcast

我目前正在努力解决以下问题： 我有一个Java EE应用程序，应该能够在一个集群中运行（实际上是这样）。 对于节点之间的数据交换，我使用Hazelcast 3.3.3。 由于我们的客户害怕UDP，我们使用TCP。 所以我为每个节点configuration3个hazelcast参数：使用的networking接口，端口和集群成员。 在现实生活中（不是docker环境），一切正常。 现在我想把我的Java EE服务器放入Docker容器（每个节点一个），并通过Hazelcast链接它们。 我做的是： 在运行docker容器的主机上，我创build了几个虚拟networking接口（172.21.0.X）。 对于每个docker集装箱我给了networking映射像-p 172.21.0.X：5190：5190（5190是我用于Hazelcast的端口） 在我的Java EE应用程序的容器内我configuration了hazelcast来监听接口172.21.0.X，端口5190成员172.21.0.X：5190，……现在的问题是：docker会分配一个内部的IP号码到每个钱柜。 提前我不能确定哪个IP号码docker将分配。 它最初不是我想要使用的IP（172.21.0.X）。 Hazelcast启动并告诉我：找不到匹配的界面。 当然不是。 Hazelcast会检查Docker容器的IP接口，类似于172.4.XX。 这不适合我给hazelcast的configuration（使用172.21.XX）。 到目前为止，似乎没有可能指定docker集装箱的内部IP号码。 我可以从一个正在运行的容器中查询，但是这太迟了，因为我需要在启动容器之前configuration我的Java EE服务器。 有什么提示？ 是否有可能使用TCPIP运行Hazelcast？
