e.g. as follows- siteIP="10.147.112.139" ----- IP Addrsss of Site A app="sdnc" --- app name is sdnc corednsHost="10.147.114.7" ----- IP address of core-dns master |
4. Make sure that sdnc.dnsswitch is properly configured with the ssh key name
| Code Block |

#! /bin/bash
####################################################################################################
# sdncDnsSwitchWrapper.bash: Wrapper script to invoke SDNC DNS Switch for domain: sdnc.example.com #
####################################################################################################
source site.conf
ssh -i coredns.key root@$corednsHost "/home/ubuntu/dnsSwitch.bash $siteIP $app"
exit $?

5. Following are the steps to create core-dns ssh connection with sites
| Code Block |
|---|
a. Execute below command /home/ubuntu on coredns master:
ssh-keygen -t rsa -f coredns.key - This creates two files- coredns.key and coredns.key.pub under /home/ubuntu
b. Copy above two key files on site A and site B and execute below command.
sudo ssh-copy-id -i coredns.key root@<corednsHost>
c. verify below command works for root user without any prompts(because the key was added with root user):
ssh -i /home/ubuntu/coredns.key root@<corednsHost> |
