RE: Can't get SRV records from Mesos-DNS

[Andras Kerekes]

Hi Itamar,

 

You need to change the dns name you’re querying for a bit:

 

Use dig _search3d._tcp.marathon.mesos

 

See: https://mesosphere.github.io/mesos-dns/docs/naming.html#srv-records

Subject: Can't get SRV records from Mesos-DNS

 

Hi,

 

I just set up mesos-dns with my mesos+marathon cluster, and it appears to be 
working fine, but I can't get SRV records.

 

mesos-dns executed by running: $ sudo /usr/local/mesos-dns/mesos-dns -config 
/usr/local/mesos-dns/config.json

 

verified to be working by running "dig" from another machine after updating its 
/etc/resolv.conf:

$ dig +short search3d.marathon.mesos

10.240.76.32

10.240.175.55

 

not sure though how to get SRV records for the service port numbers...

$ nslookup -type=SRV search3d.marathon.mesos

Server:             10.240.28.7

Address:          10.240.28.7#53

 

*** Can't find search3d.marathon.mesos: No answer

 

Here's the config file:

$ cat /usr/local/mesos-dns/config.json

{

  "zk": "zk://10.240.28.7:2181,10.240.168.92:2181,10.240.251.236:2181/mesos",

  "refreshSeconds": 60,

  "ttl": 60,

  "domain": "mesos",

  "port": 53,

  "resolvers": ["169.254.169.254", "10.240.0.1"],

  "timeout": 5,

  "email": "root.mesos-dns.mesos"

}

 

running latest version AFAIK:

$ /usr/local/mesos-dns/mesos-dns -version

0.1.2

 

Am I doing something wrong?

Thanks!
