Unable to hit ExterName Service domains

Networking
1

Service.yaml file:

kind: Service
apiVersion: v1
metadata:
name: google
spec:
type: ExternalName
externalName: www.google.com
ports:

  • name: https
    protocol: TCP
    port: 443

When I am trying to hit this ExternalName Service I am getting below Error
404 Http Response

Whereas, if I hit the domain url (google.com) directly from the pod getting 200 OK response.
O/p:
kubectl exec curl -n mock-test – curl -sSv www.google.com --insecure

Also I am able to achieve the example mentioned below:

you are not able to curl host name, are you able to ping ? What is the cat /etc/hosts within your POD ?

Here, the answer for your question:
/ $ cat /etc/hosts

Kubernetes-managed hosts file.

::1 localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
fe00::0 ip6-mcastprefix
fe00::1 ip6-allnodes

:point_up_2: you forgot to answer this

You do not have a DNS entry resolving external Host Name. that’s your issue.

Thanks
