Kubernetes Beginner Tutorial 4 | Basic Architecture of Kubernetes - Part 1

Today we will learn:
Basic Architecture of Kubernetes
An overview of Kubernetes components
The basic architecture of Kubernetes
What is Master, Worker, Pods, Cluster
#KubernetesBeginnerTutorials
When you deploy Kubernetes, you get a cluster
A cluster is a set of machines, called nodes
A cluster has at least one worker node and at least one master node

In earlier days of Kubernetes, worker nodes were called minions
In Kubernetes, every cluster has at least one master node and at least one worker node
There can be more than one master nodes in a cluster to provide a cluster with failover and high availability
There can be multiple clusters in Kubernetes architecture

The worker node(s) host the pods that are the components of the application
The master node(s) manages the worker nodes and the pods in the cluster

In a Cluster Kubernetes supports:
No more than 5000 nodes
No more than 150000 total pods
No more than 300000 total containers
No more than 100 pods per node

This is the most easiest series I came across on youtube. There are 1000 plus videos, but the content you are providing is so easy. Thank you for you hard-work and dedication.

I hope you find this message I cannot thank you enough for putting out such content for beginer like me.. Thanks a Ton !!!

[harshbhavsar]

Maximum k8s supports:
5000 nodes
150000 total pods
total containers
100 pods per node

Multiplying all this will get which is that I will thank you such many times.
Thank you for this amazing series ❤️

Hello Raghav,
Firstly thanks a tonne for all your detailed step-by-step videos on most of the tech happening topics.
They have helped me a lot in my day-to-day professional activities.

I request you to make a detailed video on Test Containers.
I am Requesting this because I am totally into Microservices architecture and its testing, and I need in-depth knowledge on <Test Containers> now.

Thanks,
Bharath

[wisesan]

Very simplest way of understanding K8s. Thanks for the clip.

[rekhavijayan]

No works to say such a wonderful presentation Raghav

[valusanikil]

Great work sir, Big fan of your work.

[lakshmidurgatatholu]

Clear explanation.... thank you so much 🤝

[rohitmohan]

Hello Raghav..Very nicely explained. Just a query, in the very last slide of summary, it says, "Pod can be Physical m/c, Virtual m/c or Visual m/c on cloud". Shouldn't it be "Node can be Physical m/c, Virtual m/c or Visual m/c on cloud"?..Thanks, Rohit

[prakashbtw]

Thanks for your video, have been waiting for 9 PM

[mwinetimothy]

HIi Raghav, thanks for the good work you are giving. You said a cluster can't have more than 150000 podes, but if we had 100 podes per each of the 500 nodes then we would have podes in a cluster. which is above the 150000 podes in agiven cluster. How is Kubernetes working around this kind of kind of issue?

[venkateshperumal]

Thanks a lot for  your time. there is some confused statement about Node and Pod definition ( in this Video, you mentioned same definition for Node and Pod. can you please correct it - 3 mins, 5.16 mins)

[southern_smacker]

Hadoop cluster has same setup of master, slave and heartbeat from slave which sends master “I am alive” kind of message every 30 second or so.

[VigneshVignesh-ojgy]

Hello Raghav,

Thanks for the clear explanation.
Having 1 query

Master node also have pods ? like worker node

[johncpope]

There is a limit of 5, 000 nodes. There is a limit of 100 pods per node. The maximum number of pods should therefore be 500, 000. Who arbitrarily lowered the pod limit to 150, 000?

[YatanveerSingh]

Is worker node and Bin the same thing ?
