You explain things really well. I hope once you go into technical and hands on part, the videos will be longer. Because it's better to learn in depth, also people who want to learn will have patience to watch long videos. Also please don't use too much layman term to explain technical concepts, if it's gets little difficult to then no problem, somone who wants to learn they won't have a problem in doing a little research, I have seen vidoes where people try to explain cloud computing using example of people living in society etc., I really don't like that approach. 😂 You can create short videos separately to explain quick concepts in less time, maybe create a short video series where you explain one particular topic within a minute, e.g. Explain what Scheduler do in k8s within a minute. These are just my personal suggestions, maybe that's my preference about learning things, again the way you explain things is great.

@@natural_stupidity_ These are some very valuable suggestions, thanks a ton! This is actually one of the debates I have with myself before every video - should I just assume technical terms and give 1-2 lines of description about them. And yes, the hands-on videos are much longer :) Really appreciate your insights on this

This is truly a masterpiece. Especially how docker images build and deployed in K8 cluster. Really amazing with great presentation. Thank you very much my pal.

Hi, Raghav! I've just comed accross your video and really like the way you teach. I already subscribed to your channel. Please don't stop the good work! Go ahead! I just talked about your channel to a freind and shared the link of your first video on Kubernetes with him. Thank you, so much!

Thanks for the feedback Vikram, this is a very practical one and I'll be working on this soon!

K8s detects the container pod has crashed, this can be done using health check probes. It then restarts the pod using the restart policy ("Always"). Again scheduler attempts to find the right node for the pod. Once the pod is scheduled, the controller manager notifies the API server to move pod to the desired state. API server informs kubelet to make the pod into running state.

BINGO! Once you understand these flows, 70% of the troubleshooting issues no longer take much time

This is awesome , just a question was there no role of the kube-proxy ?

Kube proxy does have a very important role of handling the networking for each pod, maybe I should've shed some light on that as well.

So Who creates pod? Container runtime and kubelet?

@sre101

4 күн бұрын

Ultimately the Kubelet is responsible for starting the Pod and the containers inside it in a worker node. So yes, Kubelete + Container runtime

If the running pod crashes then depending on the restart policy the kubelet will try to restart the pod, but if it fails to do show then a new pod will require to be launched, the scheduler will schedule this pod and then the CM will instruct the kubelet via api server to launch this new pod. I might be wrong, let me know.

That's the correct flow! In computer systems, understanding request flows solves 70% of your troubleshooting problems.
