Day 10/40 - Kubernetes Namespace Explained - CKA Full Course 2025

[@AbdulRehman-n4b5d]

This is the first playlist I have followed regularly and still do.

[@TechTutorialswithPiyush]

Thanks a lot 🙏😊

I know sometimes our expectations for our growth can discourage us at times when we don't see the results in the timeframe we desire. One thing is for sure; you will exceed all expectations that you have in due time. You put in the work, and you truly care about your craft. It is only a matter of time Piyush. Thank you for all you do.

[@TechTutorialswithPiyush]

I am sure it will happen eventually. I dont believe in overnight success, it took me 3 years to reach to 28k subs, 10 years to get into a Faang company, 4 attempts to clear my first cloud certification, and many more failed attempt to get my first devops job. I believe in consistency, hard work and process oriented approach rather than a goal oriented approach. Thank you for all your support!

Excellent video One request Can you also create video on creating homelab for practice

[@TechTutorialswithPiyush]

Thanks a lot! It's already there:- Check out the video #6 and there will be one more way of kubeadm installation in upcoming video #27

[@akifsalah9686]

So these Namespaces wiil be created inside worker Node and its like a logical grouping of resources (like pods, services, and deployments) within the cluster.. Have I understood Correct

[@TechTutorialswithPiyush]

Its partially correct. Yes it is a logical grouping of these resource within the cluster but a namespace spans across all the nodes. When you create a ns, you can then create a pod in that namespace and using nodeselector or taints/tolerations, you can schedule that pod on a particular node or even control plane node. These scheduling concepts will be discussed in the upcoming videos.

Relax bro, I am a human not an AI, I have a family , I have a full time job (9-5) , I have a personal life even then I am publishing 4 videos everyday. To get the most of it, complete the tasks given in every video

[@kundanchannekar8048]

Hey Piyush, I see the different behaviour on my kubeadm cluster hosted on virtual box. I created the same namespace as you have mentioned, however I can ping the services from pods on different NS with ClusterIP, however when I tried with hostname I did not get any result also I tried with the FQDN but that also did not worked. The only thing worked is the ClusterIP.

[@kundanchannekar8048]

Could be an issue with my kubeadm cluster, I cross-checked it with my eks cluster where it worked as you showed. Thank you....

[@TechTutorialswithPiyush]

Looks like you are having issues with DNS resolution. CoreDNS is responsible for that. Check if coredns pods are healthy or not. If you are facing issues with that, open an issue in our discord server and I will help you

[@madhuppandey3151]

Hello piyush, I have setup the k8s cluster using kubeadm and I tried this video's tutorial as it is but it is not resolving my dns I am using the 1.29 version on k8s and I have also used FQDN but still no luck

[@TechTutorialswithPiyush]

Can you check if your coredns pods are up?

[@madhuppandey3151]

@@TechTutorialswithPiyush yes all the pods in kube system are running fine

Kubenetes sometimes has more complexity

[@TechTutorialswithPiyush]

Sometimes? No , it always has much more complexity but this series was meant to be from beginners points of view, I have introduced the complexity but in a progressive way. A lot has been covered, a lot will be covered in the near future
