Hi Naveen; You are right, but I still need guidance.
Cluster is deployed on AWS. [root@ip-10-20-4-38 network-scripts]# cat /etc/resolv.conf search hazelcast-ocp.com nameserver 169.254.169.253 [AWS DNS] And override it and I noticed that origin also add its dispatcher. [root@ip-10-20-4-38 /]# cd ./etc/NetworkManager/dispatcher.d/ [root@ip-10-20-4-38 dispatcher.d]# ls -l total 28 -rwxr-xr-x. 1 root root 175 Sep 12 2016 00-netreport -rwxr-xr-x. 1 root root 100 Aug 18 2016 04-iscsi -rwxr-xr-x. 1 root root 1120 Aug 9 2016 11-dhclient -rwxr-xr-x. 1 root root 442 Jun 23 2015 20-chrony -rwxr-xr-x. 1 root root 52 Apr 17 09:43 99-awsdns [added for AWS DNS, and overrides resolv.conf] -rwxr-xr-x. 1 root root 4000 Apr 17 10:30 99-origin-dns.sh [Origin added after installation] -rwxr-xr-x. 1 root root 719 Dec 23 11:37 cloud-init-azure-hook drwxr-xr-x. 2 root root 6 Mar 29 12:03 no-wait.d drwxr-xr-x. 2 root root 6 Mar 29 12:03 pre-down.d drwxr-xr-x. 2 root root 6 Mar 29 12:03 pre-up.d I needed AWS DNS to resolve host names in order to complete installation successfully for ssh connections, required by ansible playbook. And I am probably missing smh here. I followed installation guide from [https://docs.openshift.com/container-platform/3.5/install_config/install/prerequisites.html <https://docs.openshift.com/container-platform/3.5/install_config/install/prerequisites.html>] VERSION [Container Platform 3.5] [root@ip-10-20-4-38 dispatcher.d]# oc version oc v3.5.5.5 kubernetes v1.5.2+43a9be4 features: Basic-Auth GSSAPI Kerberos SPNEGO Server https://master.hazelcast-ocp.com:8443 openshift v3.5.5.5 kubernetes v1.5.2+43a9be4 Kind regards > On 26 Apr 2017, at 14:37, Naveen Kumar Tangallapally > <naveen.tangallapa...@cloudgensys.com> wrote: > > Hi Baris, > > can i let me know the steps for setting up for the DNS. > > because my ods are going in error state. > > Regards... > > > > Regards.... > NAVEEN KUMAR T > Openshift Administrator > Mob:+91 9550220793 > naveen.tangallapa...@cloudgensys.com > <mailto:id%3anaveen.tangallapa...@cloudgensys.com> > > > On Wed, Apr 26, 2017 at 5:02 PM, Barış Aydınöz <ba...@hazelcast.com > <mailto:ba...@hazelcast.com>> wrote: > Problem: > > A Pod in Master can ping to a node in Node, whereas trace path fails.
