[GitHub] [dubbo] fl061157 opened a new issue #8726: 容器上使用DUBBO 为什么2.7.12版本 Bind端口强制使用了注册端口号，导致容器下无法正确访问
fl061157 opened a new issue #8726:
URL: https://github.com/apache/dubbo/issues/8726
2.7.8 版本代码如下。
ServiceConfig.java
方法 findConfigedPorts
代码
map.put(BIND_PORT_KEY, String.valueOf(portToBind));
2.7.12版本代码
ServiceConfig.java
方法 findConfigedPorts
代码
map.put(BIND_PORT_KEY, String.valueOf(portToRegistry));
有什么特殊的考虑吗？

> 你好，我们使用的是 NodePort 模式。 注册到注册中心的是 Node 的 IP ， 因此需要每一个 实例在Node 上都有唯一映射 Port（这个也是 注册到注册中心的Port） 这样才能够全部访问到。
这种情况没什么好的办法，你要用nodePort注册就是会需要开很多端口。正常上线的服务，不需要对集群外部暴露服务的吧？那使用nodePort是基于什么考量呢

// registry port, not used as bind port by default
String key = DUBBO_PORT_TO_REGISTRY;
if (protocolConfigNum > 1) {
key = getProtocolConfigId(protocolConfig).toUpperCase() + "_" + key;
}
String portToRegistryStr = getValueFromConfig(protocolConfig, key);
Integer portToRegistry = parsePort(portToRegistryStr);
if (portToRegistry == null) {
portToRegistry = portToBind;
}
// save bind port, used as url's key later
map.put(BIND_PORT_KEY, String.valueOf(portToRegistry));
return portToRegistry;
}
感觉上面的代码，将
map.put(BIND_PORT_KEY, String.valueOf(portToRegistry));
改成
map.put(BIND_PORT_KEY, String.valueOf(portToBind)); 更合适一点。
绑定端口和注册端口是可以不一样的。这样就和以前一样，能解决@ fl061157 提出的问题了。

dubbo3.0.4也有这个问题，只设置了DUBBO_PORT_TO_REGISTRY=20881，但是监听端口也变成了20881，只想让上报到注册中心的端口变

本质上逻辑和2.7.8是没区别的，只是只能用一个配置端口而已，毕竟也无法配置两个不同的端口

你说的是多个实例分别在不同的容器里，ip和端口怎么设计是么？
为啥会存在同一个ip，多实例用不同的端口的情况呢？
假设是我说的那种case，就用环境变量注入ip和端口可以了，容器外能访问通的地址就行

这个是为了解决这个case： #7656
把DUBBO_DUBBO_PORT_TO_BIND和DUBBO_PORT_TO_REGISTRY两个配置统一了。
如果DUBBO_PORT_TO_REGISTRY指定了就用这个；没指定就用DUBBO_DUBBO_PORT_TO_BIND。
ps：我觉得这个代码的写法确实不是很合适，如果是我会这么写：
portToBind = portToRegistry == null ? portToRegistry : portToRegistry;
map.put(BIND_PORT_KEY, String.valueOf(portToBind));
这样可读性会高一点；
我后续调整一下。

这个问题我也发现了。服务绑定的端口是容器内的端口，而上报到注册中心的端口应该是宿主机的端口。比如内部IP和端口是IP1:Port1，上报到注册中心的IP和端口应该是宿主机的IP端口，比如IP2:Port2。 容器负载配置port2映射到port1。主机外的消费者看到的服务提供者的地址是IP2:Port2。因为消费者不能直接通过IP1:Port1访问服务。将请求发给IP2:Port2，然后宿主机将其转发到内部的容器实例IP1:Port1。
dubbo这么一改后，业务配置的绑定端口port1就无效了，直接监听端口DUBBO_PORT_TO_REGISTRY，即port2了。以前端口映射配置是port2->port1，现在就变成了port2->port2了。port1就没用了。
