Cleaning up DNS records

Identify the CNAME records that I need to remove:

for i in $(grep CNAME slaves/osop.cloud.lab.x.x.x.com | awk '{ print $1 }'); \
  do echo "update delete $i.osop.cloud.lab.x.x.x.com CNAME" >> \
  /pub/projects/openshift/ddns_configuration/zone_update.txt;  \
done 
 

Do a bit of cleanup:

vi /pub/projects/openshift/ddns_configuration/zone_update.txt 
 

nsupdate -k /var/named/Kosop.cloud.lab.x.x.x.com.+157+06745.key -v \
/pub/projects/openshift/ddns_configuration/zone_update.txt 
 

rndc freeze; rndc thaw; service named restart 
 

vi slaves/osop.cloud.lab.x.x.x.com 
 

for i in $(grep TXT slaves/osop.cloud.lab.x.x.x.com | awk '{ print $1 }'); \
  do echo "update delete $i.osop.cloud.lab.x.x.x.com TXT" >> file1;  \
done 
 

cat file1 >> /pub/projects/openshift/ddns_configuration/zone_update.txt 
 

vi /pub/projects/openshift/ddns_configuration/zone_update.txt
