Steps

• Create a DNS zone using task-011-route53 and get the zone name and zone_id. The zone I created was k118.tk. Also I created the domain k118.tk in myfreenom.com.

Apply complete! Resources: 1 added, 0 changed, 0 destroyed.

Outputs:

devopslink-name-servers = [
  "ns-1347.awsdns-40.org",
  "ns-1667.awsdns-16.co.uk",
  "ns-384.awsdns-48.com",
  "ns-999.awsdns-60.net",
]
devopslink-public-zone-id = Z099337627DO5QQDVQEVD

• Assign those values in the variables file in this task. Also make sure that you assign these nameservers to the domain k118.tk you created earlier. Visit the website https://my.freenom.com/ and go to the setting for you domain. Check the setting for changing the nameservers from freenom's default to the ones you just created above. For more details about this you can check the task-22-route53-ec2

$ kubectl get nodes

ip-10-0-0-102   Ready    <none>   2m21s   v1.18.5
ip-10-0-2-187   Ready    <none>   3m39s   v1.18.5

• Check the pods in kube-system namespace

✗ kubectl get pods -n kube-system
