Problems with multiple eips and TXT? about eureka HOT 6 CLOSED

Curious whether you tried with the actual TXT record having a comma between
entries as suggested by the wiki? If yes, does that work?

I ran into some issues when I tried to setup multiple zones with eureka.
According to the wiki, the txt records should be separated with ','.
However, it seems like the code is using the whitespace character?
Wiki page I am referring to:
https://github.com/Netflix/eureka/wiki/Configuring-Eureka-in-AWS-Cloud

But on this line it splits using whitespace:

https://github.com/Netflix/eureka/blob/master/eureka-client/src/main/java/com/netflix/discovery/DiscoveryClient.java#L1366

This would be fine if it was as simple as a code->wiki mismatch. But when
there is a whitespace within a txt record it returns it as "eu-west1a
eu-west1b", instead of with comma as eu-west1a,eu-west1b (hard to
illustrate but in the first case it returns a string containing actual
quotation marks). So when it splits it winds up with:

• "eu-west1a
• eu-west1b"

Which of course causes problems.

Am I the only one who ran into this issue? Like the way that the
TXT-records and automatic assigning of EIPs but it's very fragile to have
only one eureka server.

@NiteshKant Well yeah, that was the first thing I tried. That ended up just like trying to connect to
"ec2-54-216-23-251.eu-west-1.compute.amazonaws.com,ec2-54-216-23-251.eu-west-1.compute.amazonaws.com:8080"

which of course didn't work which was when I started stepping through the code and found that it was actually splitting on a whitespace:

String[] cnames = txtRecord.split(" ");

Hi,

Yes - the wiki has to be fixed. I think you are probably getting the format of the TXT record wrong. I think the TXT records should be similar to this

"eu-west-1a" "eu-west-1b".

Can you try this and let me know?

@karthik-vn It ends up the same. Tries to query like
txt."eu-west1.mydomain.com

Which doesn't work. According to the route53 documentation, multiple values should be one per line. But that doesn't work either. I had a fix before that just did value.replace(""", "") which worked. But I should be able to use your jars and not need to modify my code.

Not sure what is going wrong in your case. Our route53 configuration works perfectly.

For eg. here is the TXT record for our test environment.

http://www.dnswatch.info/dns/dnslookup?la=en&host=txt.us-east-1.discoverytest.netflix.net&type=TXT&submit=Resolve

@karthik-vn thanks. The issue was the setup in route53 that I had made. The test link helped me narrow down the issue with my configuration. It's working now.

The wiki should be updated to match our discussion here
