Day 5/40 - What is Kubernetes - Kubernetes Architecture Explained
Рет қаралды 4,465
Күн бұрынWelcome to Day 5/40 of the CKA(Certified Kubernetes Administrator) Full Course; we will cover the fundamentals of Kubernetes, including the Kubernetes Architecture and its components.
In this video, you'll learn:
- What is a control plane, master node, and worker nodes
- What are pods and containers in Kubernetes
- Control plane components such as ApiServer, Kube Scheduler, Controller Manager, ETCD, Kubelet, Kube-Proxy, etc
- What happens in the cluster when a user sends a request to the cluster using the Kubectl command
- How control plane components interact with each other in a Kubernetes Cluster
🚀 Reinforce your knowledge with practical tasks in the Day 5 folder of our GitHub repository: github.com/piy...
👨ðŸ¼â€ðŸ’» #40daysofKubernetes Challenge:
Join our 40-day challenge and solidify your Kubernetes skills. Details can be found in the "#40daysofkubernetes.md" file on GitHub or by watching our Day 0 video.
📖 Course Schedule:
I'll release 3-4 videos per week and host live Q&A sessions on weekends to answer your questions and guide you through the CKA certification process.
🕵ðŸ»â€â™‚ï¸ Who Should Watch:
This CKA course is designed for beginners, college students, and working professionals who want to learn Kubernetes from scratch, prepare for the CKA certification exam, or enhance their knowledge. It was designed based on the latest curriculum for the CKA exam in May 2024 and uses 1.30.2 as the Kubernetes version.
Let's start your Kubernetes journey together!

Hey Piyush, awesome work! Bro. Just a quick suggestion: consider making your profile picture smaller so that the content is easier to see.
@TechTutorialswithPiyush Ðй бұрын
Thank you Balraj! Actually it helps with keeping the session interactive. I would saved 2X time, had I recorded the videos with the cam on, 2X time saving in recording and 2X time saving in editing but that wouldnt be a good session and people will start losing interest. I had to keep the cam to a minimum size to keep that interaction but I truly understand your concern. It shouldnt hinder the visisbility. I will work on that definitely, thank you once again. This series has been recorded already but I will make some changes for the future videos.

Hi Piyush, Excellent explanation and easy to grasp without getting overwhelmed. Also, can you explain role played by controller manager here 19:33. It was not covered in kubectl create pod process explanation. Thank you.
@TechTutorialswithPiyush Ðй бұрын
controller manager controls all the controllers in the cluster such as node controller which ensures that your node is healthy all the time, deployment controller that ensure that your pods are restarted when crashed and so on. It monitor the cluster and make sure that your desired cluster state is matching with the actual cluster state. It talks to apiserver and apiserver communicates the action to be performed to Kubelet

@karnajeetsawant5635 Ðй бұрын
Awesome explanation Piyush, I really loved the video and understood almost everything.. I have few doubts though. 1. So when the pod is being created, will there be 2 entries in ETCD by apiserver? First entry about the fact that a pod has to be created and the second entry after the pod has been created. Right? 2. Does a node have any limit to the number of pods it can create? 3. Does ETCD have any space constraints or is it elastic?
@TechTutorialswithPiyush Ðй бұрын
Thank you for the feedback. Let me try to answer: 1) One entry that pod will be created and then it will be updated with the additional details such as nodename on which it is scheduled , last transitioned time, created time, last updates and other metadata. 2) Number of pods in a node is equivalent to number of IPs available, Node is eventually a VM with a dedicated IP assigned to it, also, the capacity of the node CPU, memory, disk etc. This concept will be more clear in day16 video in which I have shared the details about resource request and limits. 3) ETCD is a database and like every DB it will have the space constraints. In one of the later videos, I have discussed how you can setup etcd in multi availability mode, you can also check defragmentation process in ETCD. Hope this helps.

what will a controller manager do in master node?
@TechTutorialswithPiyush Ðй бұрын
Controller manager is a collection of several controllers that ensure that your desired infra state is always reached. For example, if a pod crashes, it instruct the kubelet to restart the container.

Hey pyush Is it possible to modify etcd data which is stored
@TechTutorialswithPiyush 8 күн бұрын
As it is a key value store, you can query the db, but not something that we usually do etcd.io/docs/v3.5/tutorials/writing-to-etcd/
@debillion Ðй бұрын
what is then the difference btw etcd and kube config?
@TechTutorialswithPiyush Ðй бұрын
kubeconfig has your context , authentication details using which you login to the cluster. kubectl uses kubeconfig to authenticate the client to apiserver. etcd is a key value datastore that stores all the configuration data and your cluster state.
