[@FabianoChagas]

The videos you produce should be part of the official kubernetes trainings.
thanks for sharing

[@THIRSTYGNOME]

Your videos blow the Linux Foundation training out of the water. So clear and concise.

[@SnowboardPlata]

Thank you so much for making these videos and explaining so thoroughly instead of assuming that us new folks know already what much of the terminology means.

[@derrickgraffam2249]

Thank you for explaining how usually you will run everything with a kubectl apply -f. When I first started learning the other way then it was confusing to just go over doing all the setup with a single command. Really enjoying your vids in general.

[@ashishbadgujar8215]

Expecting this a year back from you, coz I love your way of teaching :)

[@daddydoescomedy]

Thank you so much for these videos you've made learning kubernetes a little bit easier

[@gentreshtani826]

And he's back, everybody!!!

[@Itsme-kx1us]

Tq soooo much sir for providing this amazing content at free of cost 🙏🙏🙏🙏

[@abdisamaddheere9765]

Welcm back boss, missed your videos on kubernetes, i would like to see GKE with terraform and Gitlab CICD on top of kubernetes.

[@SnowboardPlata]

Would also love to see a gcp gke in terraform. Also databases on kubernetes

[@Shubham__Saroj]

This video is one of the best. I have been waiting for it. Thanks a bunch 💪😊

[@andreigiubleanu]

Marcel is the boss !

[@ashishjullia638]

Beautiful content

[@dillonhansen71]

We are blessed yet again by another knowledge drop from the lord himself.

Kubectx for contexts switching!

[@zenobikraweznick]

Me: trying to do something with k8s cluster with some UI tools
Kubectl: Dude, Do you even lift?

[@philc787]

Fab 🎉

[@argokabyken9268]

How does your service select your deployment pods, since you didn't provide labels or selectors, or used kubectl expose on it?

[@MarcelDempers]

Very good question. I did not realise but I believe when using "kubectl create service" and specifying the service name the same as the deployment name I believe it will use a selector to match the name of which the service was created by.
Now because my name of my deployment and service is the same, their selectors and labels happened to match.
I probably should have shown the selector explicitly

[@jdubeau007]

at 16:44, why wouldn't you merge the config and switch the context. Let say one context for Docker-Desktop and another Digital Ocean (kadmn) cluster.

[@MarcelDempers]

for some, keeping environmental config separate helps. Prevents mistakenly access incorrect contexts and requires intentional config switch to make that mistake

[@jobinjose5215]

Is there a way you can deploy to kind cluster using azure devops cicd?

[@MarcelDempers]

You could use something like Flux or a GitOps approach to pull things into a kind cluster. However, I would avoid hooking up CI/CD pipelines to kind since kind is purely for local k8s testing

[@kalindusekarage5951]

Great content Marcel. Does Kind support Nvidia GPU?

[@MarcelDempers]

I have no idea. GPU is not something I've explored before

[@kalindusekarage5951]

@@MarcelDempers Thanks for the reply. If you got a chance please make video on how to enable GPU in kubernetes.
