Thanks for the Excellent explanation of CoreDNS, Piyush!! K8s networking is one such topic I find it hard but not anymore after this series of videos. And the Special guest is Abhishek Veramalla 🌟
I promise none of the Kubernetes topics will be difficult once we finish this series. I have a lot more Kubernetes videos planned after this series. About the guest, I guess you have to wait till monday for that :)
Hi Piyush! Thanks for the great content. Now it's day 31 for me and stuck with nginx1 pod name resolution from nginx pod. I have a local cluster and properly installed with calico. resolv host files are correctly pointing to the kube-dns IP address. I am able to curl nginx1-service service name from nginx pod, also with their respective IP addresses. I did some research and applied a headless service selector (clusterIP: None) for the nginx pods but didn't help... I've also tried the FQDN to resolve the name, again no luck... Also the dnsPolicy is set to ClusterFirst. Could you share the yaml files for both pods and services? I believe I have correct definitions in the yamls, I'd like to try the yamls you used to set up the pods & services. Thanks!
Adding extra nw add on like Calico will required only of we are using kind clusters. Right? What if we are working in Eks or K8s? Will the coredns pods/deployment available by default?
Hi Piyush Sir, Thanks for making such a easy and understandable content. If I had a power to write 100 genuine comments and likes then I would have done it. But please take this single comment as a power of 100 comments and likes. Thanks again!
You are saying 10! I have created 42 videos in the series about Kubernetes, have you started from day0 video? if not , please check it out. Once this is done, I will be adding many more important Kubernetes concepts to the list.
Hey, Thank you for the feedback. Just wanted to check if you watched the previous video about DNS before this? also, can you share more details about which part you found confusing? I will keep that in mind from next time
Your confusing viewers, like 1. you directly opened the kube-system namespace which you did not create and showing the pods inside. 2. As your explaining the core DNS why did you create a deployment with the name coreDNS and also you created a kube - dns service ( as you know that kube-dns is replaced with the name coreDNS. 3. if you want to show something and explain clearly please show us the with the yaml files for deployments and services. even your video is a continuation of a series try to be specific because we search in the youtube with the specific topic and learn. I opened your video with your thumbnail but the content is confusing from the first itself. A beginner will loose motivation. My request is be specific and clear. Thank you
Relax bro, no one is confusing anyone. This is a series, you cannot expect me to cover all the prerequisites in a single video that is why it's a series, I could have created a single video of 20 hours long only then it would have covered everything. Even Docker, dns, namespaces, pods, deployments, kubernetes architecture and 30+ other topics are prerequisite to this video and same in every video, how can you expect me to cover everything every time 🤯 This series was created keeping beginners in mind, If I can spend 40 sleepless nights just to create one single series, a beginner can atleast take some effort to start from the beginning.
thank you for your hard work!!!
Appreciate it! 🙏
Thanks for creating such wonderful content
You're welcome! 😄

Hello Anil, I am glad you found the video worth spending your late night on. Thank you
Thank you for the explanations on DNS inside of Kuebernetes
Glad it was helpful!
Thanks for sharing Piyush! I’ve had a hard time understanding the core-dns setup in kubernetes and this clearly explains what I was missing out

Hi piyush latest version of kubernetes as of aug 24 is 1.31
Yes, the video was published before it but there's no change from the exam perspective
Adding extra nw add on like Calico will required only of we are using kind clusters. Right?
What if we are working in Eks or K8s? Will the coredns pods/deployment available by default?
Thanks Piyush, my guess is like Abhishek Veeramalla for explaining the k8s networking concepts. I will be waiting for the next session
I guess you will find out soon :)
Thanks FYI, kindly explain about networking in kubernates which about iptable, Cgroups and CNI, how pod assigned IP
Yes, it's already there in the queue, will be published in the coming week
@@TechTutorialswithPiyush thanks much piyush, really you are doing grea!
Bro, could you please explain the helm chart topic.
Yes, let me finish this series first. Then I will also create detailed tutorial about Helm charts.
@@TechTutorialswithPiyush thank you so much brother🧡🧡
Kustomize also please :). Appreciate you time and efforts in creating the content
@@josephrajareddy4606 sure sure
Hello piyush one question....
Like this is more than enough for cka exam
Hello , Yes, if you complete this series plus all hands-on exeercises in the Github repo, it is more than enough
Hmm , next topic on Networking and all the world relies
A lot more is coming , stay tuned

Hello Kunal, This sweet gesture is worth more than 1000 likes and comments! I truly appreciate it
🎉
😍
Bro can you make 10 different tutorials about kubernetes clearing everything one by one example would be great

@@TechTutorialswithPiyush yes just saw that 😂. Thanks for ur hardwork man. Keep up the good work 👍
@@asntechies8017 No problem 😀 I'd recommend starting from the beginning to get maximum benefits from it.

Is he Abhishek??
You will find out next week
This one you couldn’t explain properly. It’s confusing.
