I have setup my kubernetes cluster from scratch following this doc: https://kubernetes.io/docs/getting-started-guides/scratch/
My kubernetes master and worker are working correctly, but I didn't find the instruction to deploy dns addons.

While you can run Kubernetes in many different environments, bare metal deployment is becoming increasingly popular. Running Kubernetes on bare metal comes with several advantages, including better security, less network complexity, lower costs, and complete control over your entire architecture.
Addons are critical components within a Kubernetes cluster that provide critical services needed by applications like DNS, Ingress, Metrics, Logging, etc. Addon Manager provides a CRD for lifecycle management of such addons using Argo Workflows.
Addons can be deployed through yaml files as well as using the addon manager. I have already installed dashboard, monitoring, DNS manually using the yaml files provided (with small modifications) in this repo.
Please note addon-manager is pretty special, You should copy all files into a directory then:
./kube-addons.sh
Btw I prefer installing addons manually instead of using addon manager.
DNS addon manual example:
Take the kubedns-controller.yaml.sed,
Replace the $DNS_DOMAIN with cluster.local(you should use the domain specified in your setup here). You can also set it as a variable. Please note there are multiple occurrences in this file.
Then:
mv kubedns-controller.yaml.sed kubedns-deployement.yaml
kubectl create -f kubedns-deployement.yaml
