How to set hostname for eureka-client which is registered in eureka-server?

[qiangdavidliu]

Hi @killjason the hostname should be automatically discovered by eureka-client.

[silentAllay]

@qiangdavidliu, what about the IP address?

[qiangdavidliu]

@killjason same for ip address as well. The client auto detects your hostname and IP via standard system calls, and then (optionally, if in EC2) overlays these with data retrieved from calling the ec2 instance metadata url.

@qiangdavidliu,what if the server have multi network interfaces?

[qiangdavidliu]

@killjason we don't yet support multiple interfaces.

[silentAllay]

How does eureka-client decide which ip should use if have two interfaces?

[qiangdavidliu]

@killjason if the server is running on Amazon, it defaults to eth0. Otherwise, the default interface is whatever will be picked up by InetAddress.getLocalHost().

@killjason You can pass your own implementation of PropertiesInstanceConfig to the ApplicationManager. This implementation can override getHostName() and getIpAddress() in a way you want.

@rfoltyns , I extends com.netflix.appinfo.MyDataCenterInstanceConfig to override getHostName() and getIpAddress(), is that OK?

[rfoltyns]

@killjason yeah, MyDataCenterInstanceConfig also extends this class
