Doris FE can't start ,because fail to find right address to start fe by using fqdn

[artjio]

I am using the Apache doris 2.1.4

os:ubuntu 18.0.4
java version : zulu open jdk 1.8.0.192

When I enable the fqdn is true,the log will print "fail to find right address to start fe by using fqdn"

So,i check the fe debug log,and i found the log show doris is address my ip 196.178.5.35.

but it is weird,because my true ip is 172.23.179.53

I can't find any word about 196.178.5.35. (i has been try many commend, like ifconfig,route,host,ip,nslookup)

But,if i mark enabled_fqdn=true,doris fe will be work (log is show doris find the ip 172.23.179.53)

This is my fe.conf

yes, if you want to start FE by using FQDN, you need to set this:
enabled_fqdn=true
please refer this

I'm sorry if I wasn't clear. When enable_fqdn_mode is set to true, Doris retrieves an incorrect IP and FQDN string. However, when enable_fqdn_mode is commented out, Doris can correctly retrieve the IP.

I checked the k8s configuration and found that three settings were related to the hostname. My original hostname was a string of numbers, something like 333000111. After adjusting the hostname, I noticed that the IP and FQDN retrieved by Doris changed. When I set the hostname to match the content in /etc/hosts, everything worked correctly.
