[I] [Feature] 多网卡注册问题 [dubbo]
seqwait opened a new issue, #15265:
URL: https://github.com/apache/dubbo/issues/15265
### Pre-check
- [x] I am sure that all the content I provide is in English.
### Search before asking
- [x] I had searched in the [issues](https://github.com/apache/dubbo/issues?q=is%3Aissue) and found no similar feature requirement.
### Apache Dubbo Component
Java SDK (apache/dubbo)
### Descriptions
In a Docker Swarm overlay network, some services are connected to the ingress network, while others are not. However, all services are connected to a custom overlay network. The issue is that Dubbo sometimes selects the ingress network, causing services that are not part of the ingress network to be unable to find providers.
The ignored and preferred options do not solve the issue because the ingress network might be assigned to eth0 or eth1 at startup, making the interface selection inconsistent.
Does Dubbo provide a way to prefer a specific subnet, such as dubbo.network.interface.address.prefix?

You can use `dubbo.network.interface.preferred`
FYI `org.apache.dubbo.common.utils.NetUtils#findNetworkInterface`

This doesn’t solve the problem because the container uses multiple network interfaces, and eth0 doesn’t necessarily correspond to the custom overlay network. eth0 could correspond to the ingress network or it could correspond to the custom overlay network.

You can calculate the right network interface in a bootstrap script, then set as the java properties for Dubbo
