Nana, without sarcasm -- you are doing god's work thank you. K8s docs do not cut it for actually understanding anything.

[TimRichardson_GrowthPath]

it's kind of ridiculous how good this series is. Amazingly good. If this had been my first step towards Kubernetes, I would have saved quite a lot of time. Nana has a video on why she chose devops as her career, which I have not yet watched, but if she is better at devops than she is at teaching, she must be off the charts good at devops. I suppose she really likes devops and is motivated to make this astoundingly good material to encourage others to follow her.

Thank you so much for this.

I gotta say, the more videos I watch your videos, the clearer it is about Kubernetes.

Keep up the awesome work!

[Ruben-byoy]

I'm amazed how simole those explanations are. I figured out all myself but anyway it's worth to go through one more time.
Thanks

[bgable]

OMG!!! Your explanation on "label & selector & port", @6:00, helps me understand the relationship in Home Assistants' YAML files and the components with in them. These points are greatly missing from their docs. THANK YOU!!! From ALL the reading and research, I finally found the answer. Please keep up the great work. I'll look for your courses in udemy for sure.

I reviewed a project for kubernetes at my company last week. I was overwhelmed with yaml files. I was confused about the pattern of attributes. This video helped me understand the inner details tremendously. Thank you.

[swapnilk]

Nana, Thank you for superb, simple, clear tutorial of K8.

[jayaprakashdeav]

Wow what a greate explanation, Thanks for the nice and perfect video.
so i understoond clearly
*)what is Label & selector
*)connection B/W Deployment and Pods connection

*)connection B/W Deployment and services
Please keep posting this usefull videos.

I downloaded a paid course but since i found your videos i've been following them instead.
Thank you for making this publicly available on the youtubes.
Done thanks, notes copied to onenote

[rejawebs]

Detail expiations about both the deployment and service. Thanks a lot and wishing you best ...

[nO_dNAL]

Thanks for this. I was so confused when I came across a YAML file with "spec: template: spec". I really wish the documentation explained it more simply. This video clears things up nicely

[polartechie]

It is legit comforting to click on a new subject and hear Nana's voice because I know that it will be great and I'll soon have all the context :D

[basilio]

Re: 6:59 - connecting services to deployments
Small correction - I think it is important to note.
Service manifest in service.spec.selector is using labels of pods, not deployment.
So frames at 7:12 -7:36 should not have arrow pointing to deployment (upper arrow)

Hi Nina, I started my career as a platform engineer last month and had no idea how to learn Kubernetes by myself (cuz my background is front-end and had 'some' knowledge in docker containers). When I got some tasks related to template/config in YAML format, I literally didn't know how to start or where to begin. Thanks to your amazing lectures, now I feel I'm getting used to the concept of K8S. Thank you very very much Nina. I hope you have a great day.

[amulsharma]

Hi Nana, you are such a good trainer. Thanks a lot for the session. The way u r teaching it's really good nd concepts r crystal clear. May God bless u with happiness nd success.

[whoistechcmty]

You are a fantastic instructor. Your explanation videos are direct and clear. You describe things clearly and provide context while keeping the primary focus of the lesson in mind.

[SJJ]

you are awesome Nana. Thank you for sharing knowledge with us.
