In Cluster, in addition to Cluster IP access to services, Kubernetes also provides more convenient DNS access.

kubeadm deployment installs the kube-dns component by default.

kube-dns is a DNS server. Whenever a new Service is created, kube-dns adds the DNS record for that Service. Pods in a Cluster can be accessed via. Visit Service.

For example, you can use httpd-svc.default to access Service httpd-svc.

Use nslookup to view DNS information for httpd-svc.

Deploy Service httpd2-svc in kube-public, configured as follows:

View kube-public Service:

Because they belong to different namespaces, you must use httpd2-svc.kube-public to access them.
