First thank you for your great videos, if you allow me to ask, we have setuped k8s cluster 1.18.5 using kubeadm, i have followed this video and edited kube-apiserver.yaml, but when the apiserver container restarts, it use the old configs, what is the problem in your opinion?

[RK-wkzn]

do you have any kube videos on DNS and certificate rotation? Also, is it possible to have a single 'container' with multiple images? if yes, could you please share the steps?

Hello and thank you again <3
I did all of your videos from this playlist (Kubernetes Resources) with Minikube and all of them was successfully done, except PorPreset (On Minikube), I googled it and find out there are two ways (add those line in API YAML file as you have taught, and run Minikube start with extra-config) but these two ways didn't work for me, my api-server pod in Kube-system has be en Stopped :(, If it possible to you to make a video or anything will be so useful for me.
Thank you again and again ... <3

Thanks for video.
I got stuck, When i create Pod using labels match with PodPreset but the Pod no apply the configure, describe the Pod "Annotations: <none>", i follow every single step but doesn't work. 1. deploy kubeadm; 2.add podpreset, runtime; 3. api-server create again. I try again with documents k8s, but have same result. Please take a look and help me!
