try the below command. you can include all the namespaces that you want to backup

mkdir -p /root/k8s-backup

kubectl cluster-info dump --namespaces default,kube-system  --output-directory=/root/k8s-backup

You can dump your entire cluster info into one file using:

kubectl cluster-info dump > cluster_dump.txt

The above command will dump all the yaml and container logs into one file

Or if you just want yaml files, you can write a script of some commands which includes

kubectl get deployment -o yaml > deployment.yaml
kubectl get statefulset -o yaml > statefulset.yaml
kubectl get daemonset -o yaml > daemonset.yaml

Then you have to keep the namespace also in mind while creating the script. This gives you fair idea what to do
