I have an ubuntu box out of the kubernetes cluster
My /etc/resolv.conf content
nameserver 10.3.0.1 (kubedns)
If i make a nslookup, everything works fine
nslookup spark-master-0.spark-master.ns.svc.cluster.local
Server: 10.3.0.1
Address: 10.3.0.1#53
Non-authoritative answer:
Name: spark-master-0.spark-master.ns.svc.cluster.local
Address: 10.2.0.252
if i try to use any other tool (chrome, curl, ping, wget) i get an error:
curl spark-master-0.spark-master.ns.svc.cluster.local
curl: (6) Could not resolve host: spark-master-0.spark-master.ns.svc.cluster.local
The only way is to add search .cluster.local in /etc/resolv.conf, but now i cannot use the fqdn of the nodes
any tip on how to use the fqdn ?
Update The same setup in my mac works perfect ! the problem is only with my ubuntu 14.04.3
It seems like FQDN is working fine with DNS but issue with the host system.
Can you try after changing the below entry in /etc/nsswitch.conf.
hosts: files mdns4_minimal [NOTFOUND=return] dns
to
hosts: files mdns4_minimal dns [NOTFOUND=return]
if above also not work then try putting only DNS.
hosts: dns [NOTFOUND=return]
