TechWorld with Nana -Really simply awesome thank you so much for you ...will you able to help how to start working Kubernetes where I need install easy way will you please help me any doc or video

[@nihilidron]

You rock, Nana. This brought so much light in my rough start with k8s . Thanks :)

[@ojaschopade1813]

Hi Nana, can you explain why restart policy for deployment object can not be set to Never?

[@falsepositive01]

Have you been making malware analysis videos before?

[@zackyang123]

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

[@rhoonah5849]

Agreed on both points. I have been ripping what remains of my hair out of my head just trying to understand the keys in the YML file.

[@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.

[@bgable7707]

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.

[@tanngo595]

I gotta say, the more videos I watch your videos , the clearer it is about Kubernetes. Keep up the awesome work!

[@basilio100]

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)

[@biigsmokee]

so should it be pointing to Deployment.spec.template.metadata.labels.app at 7:12 instead?

[@codingstyle9480]

What about the deployment label app:ngin-x: is it used anywhere? It is said in the video that everything starts with deployment label. It is related first to pods label and then pods to matchLabels. Is that true?

[@mightyplejaden]

@@biigsmokee yes

[@TimRichardson_GrowthPath]

that makes sense. Why would a service connect to a deployment?

[@norman28575]

Yes, here would have liked to see the mandatory naming. If everything is name nginx its everything else but clear which nginx was ment. It would have been helpfull to use as many different names as possible to see what matches to what.

[@manuelsteele8030]

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.

[@mostinho7]

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

[@TechWorldwithNana]

Appreciate your feedback Mostafa! Happy to see that my videos are so informative for you :)

[@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

[@Ruben-by4oy]

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

[@BM-el9kl]

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.

[@TechWorldwithNana]

I'm very grateful for the opportunity to be able to help you. You're welcome and thank you as well. 🙂

[@amulsharma8172]

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.

[@nO_d3N1AL]

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

[@sambeetnayak1002]

Hey ..I am new to k8s.. I feel like I should pay for watching Nana's videos.. Excellent teaching skill. Not too depth nor too high level.. Just as much as it required the core concepts. Undoubtedly much better than so called paid courses..

[@swapnilk1011]

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.

[@samjellabilla4572]

Nana, the great lecturer. Thnks so much for making such valuable information available to the world free of charge. If all were to be inclined to technological tastes to learn like the tastes of entertainments, u should have had by now million followers. However, gradually, u r getting there.

[@vbharath19]

Am using these videos for my team's training. I don't think there is a better video than yours for kubernetes. Thanks and keep them coming 🙂

[@TechWorldwithNana]

Cool thanks for sharing Bharath, really glad they are so helpful!! 😊

As most of them commented already, you videos are indeed very very helpful and I would re-iterate that your way of explaining things are so good that it is easy to remember and co-relate things. Kudos and thanks a lot. Keep uploading videos like this and keep helping us. Thanks once again. 🙂👏

I have watched all of your videos on k8s and they are much much better than any paid videos on Udemy. Thank you for making such awesome videos. :)

[@TechWorldwithNana]

Thanks so much, really happy to hear that!! :)

[@rejawebs]

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

[@maksimotrishko8843]

Hi Nana, first of all thank you a lot for such great videos and clear explanations! I would like to pay attention to small nuance at 7:11. It was a bit confusing for me (and may be for somebody else) since actually for a service it is only important to have values from Pod's labels and NOT Deployment. So as an example: label for Deployment might be i.e. nginx and for its pod i.e. nginx1. And in this case a service should have value nginx1 in selectors and not nginx to be able to serve to the pod.

[@TechWorldwithNana]

Thank you for your feedback Maksim!

At 12:02 if you use the flag “-export” it will not include most of the generated status data when outputting to the YAML

Thanks for sharing! 👍
