Kubernetes Webinar Series - Kubernetes Architecture 101

[@geekyMiss]

I can't thank you enough for this k8s walkthrough! This is the first webinar that I can say I actually understood!

[@watsonodin5110]

dont know if you guys cares but if you are stoned like me during the covid times then you can watch all of the latest series on InstaFlixxer. Been watching with my girlfriend for the last days xD

[@dillonadrien8393]

@Watson Odin yea, I have been using instaflixxer for years myself :)

[@cabc74]

I have watched other videos and even a paid course. I just understood kubernetes with this video.

[@benjaminzhou9503]

Wow, what a fantastic webinar! You made complex subject so straightforward. Learned a lot. Thank you!

[@rothschilds666]

Excellent webinar. I had a few confusions but just because im a beginner. But overall this was crystal clear and helped me a lot in understanding what Kubernetes is.

[@edgarromero4541]

Thank you very much for putting this information out there in an easy to follow manner. Keep up the good work.

[@manotewiz5838]

Thanks, it give me an overall idea of K8s.

[@krishnajunk]

This is typical usecase scenario in enterprise. This session was unique one, other session mainly explains features only.

[@SunilNagavelli]

You've saved my hair which I was pulling off for such a crisp and goodie 10,000ft overview, Wish to see more.

[@rajkapoor944]

I couldnt take the pole but this webinar was genuinely excellent. Thank you very much for this. A small error is that you didnt show us the contents of the web-svc.yaml. So we couldnt see how external services were defined. However, that was the only bit I had to rewind and understand. It was excellent! Thanks

[@alecomisario]

Raj Kapoor that's absolutely true, I would love to see that happen

[@AnirudhaBose]

I finally understood k8s! Thanks a lot, Janakiram. :)

[@dougwan8150]

Great video! Thank you

[@maheshsawaiker2492]

Good talk, one correction you don't need to expose your database for a sql injection attack, sql injection attacks happen through the web server...or whatever server is exposed.

[@RaphaelVogel]

What I don't understand here: At 42:57 you are in the web pod and look at the env variables. Why is the redis host and port in the environment of the web container? Looking at the yaml files of web pod and redis service, there is no link/reference. How does K8S know that the web container wants to use redis service? Why are the redis env variables available in the web pod?

[@sujeetkumarpadhi6581]

Raphel : Did you get your answer ? I am having the same doubt as well.

[@DagangWei]

Thank you so much for this 101 talk!

[@mallucharan1]

Thank You very much ! Feedback : Is there a playlist to start from begging in sequence , the current webinar playlist i feel the sequence is confusing

[@venkateshkristipati2509]

is there any approach that how to auto scale an pod in Kubernetes on load

[@raghavendransamarao3279]

Session well organised and presented. Thanks!

[@liblian]

Have the link to get the slide show present during the webminar ?

[@mohithtrek6325]

can you explain how you got 3 nodes, i am getting only 1 node as minikubevm, can you please help me

[@JayJay-zh6ei]

I usually find the Indian accent very difficult to acclimatize to... but this was actual very good and I enjoyed it! Many thanks!

[@johan0234523]

Very clear explanation; excellent!

[@sangramkesaridash9225]

Awesome tutorial... nice explanation from you sir

[@itsyogisha]

great session janakiram! , very informative

[@UsFamilyTube]

Fantastic session Janakiram.

[@roczhang2428]

great! the concept is clear, thanks

[@MohitGupta-ju7us]

Very good session! Great!

[@sureshvishnoi111]

It's comprehensive knowledge . However, why can't we replicate redis pod as we can do with web pods? In example,​ you replicated 50 Web pods but you did not replicate redis pod ? Thanks for Sharing

[@ignasiodondo3396]

Why would you want to replicate redis?

[@techmechnegi]

because the redis one is statefull and the web one is stateless. We can scale stateless container.

[@harikiran4341]

Great explanation. Thanks

[@tvvignesh]

Thanks a lot. Really learnt a lot.

[@AnilKumar-ep1cp]

thanks

[@n1tr0g34r]

You type "clear" very frequently - why don't you just use CTRL+L?

[@m13m]

Thanks for a tip

[@markusdieterotto]

good video! very helpful

[@trigun539]

Great stuff!

[@wangminbyxy]

well short introduction to kubernetes!

[@wehappyfewkd]

Great content! Sidenote: you should really work on the pronunciation of Scheduler.

[@geekyMiss]

Make more tutorials please.

[@muhammedashique7093]

Awsome

[@mohammadarbab6058]

I hope I never get physically shed-euled

[@franceleeparis37]

Talk too much.... use diagrams... a picture is worth a 1000 words..🤔🧐

[@snbhalgat]

Very well explained, I understood so much out of your session, thank you so much. I have few questions - 1) When you logged into the web pod, you did curl to port 5000, how it know what service to be served on this port? how it recognize redis service? 2) Can you show us the svc-web.yml file ?

[@benjaminzhou9503]

thanks for the great walk through. It seems you're using a full-scale kubernetes cluster, instead of minikube. would you consider posting a step-by-step setup of a multi-nodes kubernetes cluster installation with both master and worker nodes in virtubox VMs?

[@miroslavvasko779]

I cannot appreciate it enough. We are trying to move for a "static" docker setup to something more dynamic, living setup. This webinar really, really helps. Thank you so much!

[@HelloWorld-tn1tl]

Why the google engineers like to make that weird noisy from their mouse, that I can't describe ???

[@rythsand1699]

To be frank, I referred several tutorials, videos trying to understand what Kubernetis is. I had gathered pieces of information and was finding diffifcult to connect them. This tutorial has made me to make few conclusions about Kubernetes. Awesome series.

[@juanli4276]

Fantastic video. It helps clear lots of concepts of k8s. Looking forward to more sharings.

[@mohammednasiruddin1062]

Thank you very much. Webinars should be like theirs. Great job

[@ToYobee]

The most comprehensive hands on talk. you covered all I needed to get started on kubenetes in one hour talk. Tank you so much.

[@shravankumar3717]

what does it mean if type is defined as deployment, instead of pod, service, r

[@1tahirrauf]

Great tutorial. I have one question. Issuing 'env' command in web pod's container, shows redis related environment variables. Can someone tells that how web container knows about redis??? We have not linked these two pods at any yml file?

[@oceancaster]

Because `redis` is a cluster-wide service. So it is exposed internally to the whole cluster.

[@endlesslove1010]

Hi, but do we have to explicitly state it in the yml file? Is there other options of db besides redis? Thanks.

[@oceancaster]

Yes. When you define a service you also specify its scope (if its accessible from outside or cluster or node only). For the second question, what do you mean?

[@endlesslove1010]

Thanks for the confirmation @oceancaster, please ignore the second question. Coming back to the first one, if we could define the scope, when do we define it and should we define it in the yml file as well? I didn't see the presenter specify it in the tutorial. Cheers.

[@oceancaster]

Yes. Probably the default is cluster. The presenter told this in another tutorial of this series, i don't remember when... BTW you define it in the service yml. It's the same parameter to specify an external LoadBalancer mode. If i recall it correctly it's `type`.

[@radupopa3051]

Very well made and very useful information.

Great Webnair. Too good.
