问题
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.
回答1:
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
