Your presentation and the video content is very good, able to easily understand the concepts. i find it more informative than any other udemy vidoes

Nana how to get token from hidden pod

[@danielt5542]

Nice tutorial. I think you forgot to mention what to do when we want to use a local image rather than pulling from a public docker registry. For anyone interested, you can upload a local image to minikube with: minikube image load and then run the 3:17 command

[@MUSHIN_888]

bruh that would have been good to know in the video. I wasted like 30 minutes before i found a solution. Thx for ur solution

[@mahammadshaik7101]

Great work, I gone through the many Kubernetes blogs and videos and you explained the concepts in detailed. I cleared my concepts. Thanks a ton !

[@TechWorldwithNana]

Thank you so much, glad I could help :) Hope you like my upcoming videos too 🙅🏼‍♀️

[@crazyoptimist4540]

I can't recommend your kubernetes series highly enough. You are a good person Nana.

[@mefirst5427]

I really like your Layers of Abstraction breakdown, most other instructors should learn your way of teaching.

[@mostinho7]

Done thanks Copied to onenote Editing a deployment automatically starts a new pod with the new properties and the old one is stopped Kubectl logs somePodName returns the logs printed by a pod Kubectl exec gives you a terminal into the pod Kubectl exec -it somePodName - ibn/bash Deleting deployment deletes replicaset too Creating deployment from cli instead of typing out all the configuration options we use config files 12:50 using kubectl apply which takes a configuration file and applies its contents Config file defines spec specifications for a deployment, including how many replicas of the deployment. Inside the config for deployment we have config for the pod itself, like the image it’ll use A pod can have multiple containers inside it also After making changes to the config file you save and do kubectl apply If deployment doesn’t exist this also makes it from scratch

[@technoe02]

Hey Nana! Love your videos. One small edit though, ‘-i’ stands for interactive ‘-t’ stands for TTY (teletype) which tells the terminal to behave like a physical terminal and less like a shell environment.

[@tayfun6378]

I have checked many resources but this one is so clear. I'm gonna invest myself and spend my weekend with this playlist. thank you very much and I hope you keep continue to produce.

[@mathewkargarzadeh3158]

Thanks !!! gratitude to you. you must be a very nice person to dedicate your time educating everyone thru your Channel. Work as DevOps/SRE Engineer, dealing with K8 on the daily basis ( besides the Splunk logs, kubectl describe command is my best friend how to troubleshoot ) I have a questions. would you please tell me what type of editor you are using when creating a yaml file for deployment. I use vi editor and it gives me lots trouble to get my indentation right. if you can post the url where you down-load your yaml editor I would be grateful to you. Thanks again for spreading your know how and teaching everyone here. Mat.

[@TechWorldwithNana]

Thanks a lot Mat! :) I just use Visual Studio Code code.visualstudio.com/ and put the code inside an online validator. But there are also YAML extensions you can install in VSC for built-in validation and auto-complete - just looked one up "YAML language support by Red Hat " - they also have built-in Kubernetes syntax support. I didn't try it out though.

[@sivaverrigukka5103]

use vimdiff whatever changes need to be done will be highlighted when you are comparing two files all you need to do is press the pgdwn button to the desired row and just type "do" values from right to left will be copied and after being done with changes type"esc" button in keyboard then type "wqall!" That way it saves the changes made in the file

When you are to use `exec`, bin/bash is not available for alpine images, should be using bin/sh instead. .. Just for those who are relatively new to docker..

I had the same issue. You need to create the file nginx-deployment.yaml first. Then add her code inside the file. Finally, you can kubectl apply -f nginx-deployment.yml

[@migueljesusvelasco]

[@gcpchannelforbegineers7080]

One doubt in it. Earlier you told that Database pods will use Stateful Component but in this video you use Deployment Component for Mongo db right ?

[@sanooosai]

@TechWorld with Nana please clear this doubt. We learned that pod can have 1 or more than 1 container inside it. But in K8 smallest unit is pod. How we can go inside particular container inside pod? In case of multiple container inside pod. Kubectl exec -it podname will login to which container?

[@kanchidoshi6907]

Thanks for this video. The config file that you created with the command "vim nginx-deployment.yaml", is this like a default syntax or do you have to write code from scratch?

[@ghazikhan5247]

please can you tell me what command we should type in order to save the changes in config file.Thanks

[@TechWorldwithNana]

Sure. so when you do 'kubectl edit' you actually get an editor in your command line, and which editor comes up depends on your shell configuration. I have vim. So when I edit the changes, I do 'esc' and then type ':wq'. This saves the changes and exits the editor. If you have a different editor like nano, then save it with 'Ctr + O' and exit editor with 'Ctr + X'. Hope this helps

Hey Nana, I am getting an error while doing the deployment, It says ImagePullBackOff Error. What could be the possible reason for such an error? And how do we debug and fix it?

[@bradybolton1808]

My guess is that you wrote 'image=nginx:1.16' verbatim as seen when editing the yaml file at 6:12, but you should instead be using nginx:1.18 or newer (depending on how old my comment is). Check the nginx page on Docker Hub (hub.docker.com/_/nginx ) and see the supported tags section (i.e. supported images from which kubernetes will automatically try to pull the docker image from, assuming a match is found). The page no longer contains v1.16, but the image probably existed when the video was made.
