环境信息

docker canal/canal-server:v1.1.5

问题描述

当我在canal服务器上使用docker swarm时，将启动多个容器服务，每个容器有多个网络接口，在java中接口顺序是不可控的。

怎么通过这些接口获取canal IP？

当网络接口的顺序被打乱时，以下代码将获得错误的IP。

public static InetAddress getHostAddress() { InetAddress localAddress = null; try { Enumeration interfaces = NetworkInterface.getNetworkInterfaces(); if (interfaces != null) { while (interfaces.hasMoreElements()) { try { NetworkInterface network = interfaces.nextElement(); Enumeration addresses = network.getInetAddresses(); if (addresses != null) { while (addresses.hasMoreElements()) { try { InetAddress address = addresses.nextElement(); if (isValidHostAddress(address)) { return address; } } catch (Throwable e) { logger.warn("Failed to retriving network card ip address. cause:" + e.getMessage()); } } } } catch (Throwable e) { logger.warn("Failed to retriving network card ip address. cause:" + e.getMessage()); } } } } catch (Throwable e) { logger.warn("Failed to retriving network card ip address. cause:" + e.getMessage()); } logger.error("Could not get local host ip address, will use 127.0.0.1 instead."); return localAddress; } So I want to specify the name of the network interface to ensure that the correct IP is ob

我想指定网络接口的名称，以确保获得正确的IP。
