it there for Kubernetes an option to set a DNS alias as in can be done within a host file (62.116.156.20 servera)? Where servera is an external server. As a result any pod within the cluster can get in contact to server via DNS.
Thanks

It totally depends how you configure and deploy your pods. There is an option to add a custom DNS entry to the host file of every pod documented here: https://kubernetes.io/docs/tasks/network/customize-hosts-file-for-pods/
configuration snip:
apiVersion: v1
kind: Pod
metadata:
name: hostaliases-pod
spec:
restartPolicy: Never
hostAliases:
- ip: "127.0.0.1"
hostnames:
- "foo.local"
- "bar.local"
- ip: "10.1.2.3"
hostnames:
- "foo.remote"
- "bar.remote"
containers:
- name: cat-hosts
image: busybox:1.28
command:
- cat
args:
- "/etc/hosts"
