You're literally the only RUclips creator I don't fast forward to x1.5, Sometimes I even find myself playing your videos at x0.75 speed, lol. Thank you for the thorough walkthroughs, it's hard to miss that you know a hell lot about this stuff and I hope to one day get closer to your level. Kubernetes and Helm are challenging subjects... :)
Finally, someone with awesome explaination with real world problems. Kudos.
You are Simply Great. No one could explain helm with these simplicity
Why are you not more popular!??! This content is gold.
He is definitely best.
duuuude!
Not everyone works hard to mine gold

This video is infinitely times better than helm documentation. 💪
Hi Marcel, FYI you want to be careful rolling out changes to a Redis authentication app. Redis holds the user's session in memory, and if you force a restart, no matter how graceful, it kills the user's session. If your SLA is 99.9% uptime for your customer's application, you'll get dinged. The perfect way to see if it's okay to make a change to an app without a restart is to check in Argo CD whether or not the change is incidental or integral to the application. After each commit, there's a diff feature that let's you see what the differences are before you manually commit the change to Kubernetes. You can test the change in dev, qa, and stage to see whether or not the change will force a restart. And never allow auto sync in Argo CD with any environment besides dev.
It was so very useful , we don`t even have to waste money and time on the courses site.
Thanks to you!
Very informative. You put a lot of hardwork to make this video!. Well done! Thank you.
I definitely should've watched your video about Helm before touching any Charts. It really helped me to thoroughly understand what's going on inside a Chart repo, thanks!
Little bit fast, but amazingly easy-to-understand (I do not know Helm till now) - Thanks for your time and help - Can you please go little bit slow! Overall excellent tutorial!
wow! what a wonderful video on helm introduction this is to say the least its absolutely wonderful. Please without sounding like Oliver twist i know you ask us towards the end to say what kind of video we shall like to watch next .Well i would like to see a video on running a Jenkins CICD pipeline , antifactory using helm charts
Very high quality videos, deserve more subs
Glad I found your channel! Great explanation. Easy to follow and understand. Thank you!
You are not the devops guy, you are the devops GOD 🙏
Thanks for the video, well packed and super easy to understand.
Very clear tutorial, thanks !
I really loved you video. It helped a lot.
It would be nice some tutorial using Helm with Vagrant and Ansible. I think It would be a nice tutorial. Like a end to end deploy generic application.
Thanks a lot.
I would have never imagined Boris Johnson taking up devops
Thanks very much for this video tutorial.
You have a new subscriber
Nice one brit!
Can you please do a video series on salt stack ?
Awesome!
thanks a lot!!!
Can you make a video on how to deploy multi node kafka cluster on kubernetes?
Hey man, one question: where is the k8s cluster referenced? It is not clear at all. How does kubectl know it has to control the "helm" cluster? BTW, next time call the cluster "cluster"
Not sure why you mean by helm cluster. Helm just uses whatever context your kubectl is using
Do you have any courses on Udemy?
This guy's lifting weights between videos I swear haha
You are AMAZING! Your videos are the best in case of topic kubernetes. In this video I found a great solution, how to use configmap if there is a change in values. Brilliant! Thanks your job, time and all videos what you create for us!
Simply brilliant. Not only for the awesome content, but also for the voice tone, the explanation pace, the real examples....hats off
exactly!
Yes, perfect tone and pace. Excellent job explaining the concepts involved to a beginner too.
This channel should be in the 6-figure subscribers category. Thanks man. Awesome tutorial
I can't agree more. Quality is too high
Really good tutorial man, I really liked how you explained everything in details
Very nice. Answered a lot of questions which other videos didn’t cover. I like your approach where you delete everything and start from scratch.
This video is great! I really love the step by step explanation. Also you bring a lot of context of why helm charts are useful and what advantages they bring compared to simple Kubernetes manifests. Thank you very much!!!! Spent several hours skimming through the docs and could not get half of the overview that you bring in this video! Great work sir!!!
You are my new favorite tech youtuber!!
Really helpful introduction to helm. 27 minutes well spent.
Very helpful videos. Keep it up. 👌👌👌👌
Thanks again, awesome videos as usual. I wish you made more! The key difference is that you explain the over view of what people actually want to know rather than diving into stuff that doesn't help us with the problem we are here to solve. I keep finding myself asking, is this the next thing I wanted to know? Yes, yes it is. I don't feel like there is an information gap I need to fill to understand what has been presented.
Hi Marcel You have a talent for producing excellent DevOps content
As a Developer, I delve into your space
Thanks for putting in the effort
I have viewed 6 of your tutorials in a day
Currently, I am trying to master K3S
Nico
I have found a new mentor in you. Your voice, your explanation and composure is a joy to behold. You make it so super easy!! Thank you!
Thank you very much, you are majestic.
Awesome tutorial, thanks, man! 💪
Thank you mr. devops
Epic!
I really appreciate your videos! Not only are they a good cover of the topics at hand, but they end up giving me the information I need to continue exploring. Thank you for another informational guide!
Oh my god! How good are you? Thanks a lot. Just clicked an Ad for you.
Could you please make a video how to integrate this (Helm) in a CI/CD Pipeline and SCM with Jenkins and Github?
Woww...great explaination....Im looking for Airflow on Kubernetes [ with K8'S executor ]. Can you please post a video on that
How can I find out where a chart used in a release comes from? For example, I see a wordpress release that says the "wordpress-12.1.13" chart was used. I know it's from bitnami because I installed it, but how would I know where it came from if someone else installed it?
Hi dear, Nice content, I wanted to deploy a Kafka using kubernetes and access it from the Offset Explorer, Can you please provide me information on how this can be done?
Incredible teaching.
Great video. Just for anyone trying to follow the tutorial on Windows, I was facing an error during the creation of the cluster with version kindest/node:v1.19.1, after upgrade to kindest/node:v1.25.2 the issue got away.
Tutorial is very valuable. BUT... :)
I really just have the way you do the montage. The longest scene is about... I don't know... 3sec long? :) Try to watch a movie when actor that is saying a line with 3 commas is cutted that way. It is hard to concentrate when those cuts are so visible and hearable. And those animations. A person with epilepsy can get an attack. Every time when you are putting those "TV is not working stuff" (don't know how to call it in english), I feel like someone just hit me in my face- and I am loosing concertation then :)
Hi thanks for the great video. you really made me a good devops. i have a doubt, where are you executing helm commands, is it inside the kubernetes cluster Box(VM) ? or if you are executing the helm commands in a separate VM where did you provide the kubernetes cluster info and credentials ? Please advise...
I run helm inside a docker container (so i dont need to have things installed)
You can run helm from anywhere as long as it can access you cluster.
Cluster info\credentials has nothing to do with helm. Helm will look at the same location as kubectl for a kubeconfig.
This is generally under ~/.kube/config
The cluster that has its context set as current will be the one helm will talk to.
As long as helm can access that kube config, it will use the details inside there.
You can learn more about kubectl in the second video on this playlist.
If you are new, i highly recommend the whole list

Can you make a video on digital ocean- Serverless Functions Deployment [Kubernetes + OpenFaas + Docker Image]
I really appreciate your videos, a great source of learning for me.
Currently I am having an issue with "writing a helm chart for deploying a Web application accessible to public. The Web application be calling a secure end point using a bearer token specified as environment variable"
Can yoy please help in this matter..!
Thanks in advance
Hi I get "nil pointer evaluating interface " for Values.service.port (or anything after Values.service.*) do you have any pointers?
awesome. Now I have a basic idea about HELM. I do not have to shut my mouth when my friends talk about HELM.
hahaha, you can see his passion. Very nice to watch. Thank you for taken me into your world of Helm. +1 subscriber.
Helm and yaml templating are conceptually the same as JSX and html templating. Helm templates are like components and the values are like props. Even control flow and data mapping should seem very familiar if you've used React before. Awesome tutorial!
Awesome, You have deserved more reach and subscribers. Excellent content... Kudos
Nice video. Kind of tutorial which makes you subscribe to the channel (which I did!). :)
Awesome quick start course/tutorial. I wish screen visibility was better without you zooming in.
this is masterpiece !
for anyone who cant run first command of kind. You can change the version 1.19.1 to 1.24.0 and retry it
Nice video!
Is there a reason why you created a alpine linux to run kubectl commands?
this really helped me get a grasp on helm and cleared some things up that I wasn't sure of. Thank you!
Best DevOps videos ever!!!!! Thank you so much ❤️
I have just recently discovered your channel. Awesome content. I learn more from watching 30 minutes of your videos than from a whole day of research elsewhere. Greetings from Cape Town :)
just me or does this guy look massive
Best video on Helm introduction out there! Thank youfor posting this video!
Do you have any courses on aws terraform? or things like that I'd love to purchase
annotations with checksum top trigger restart: brilliant.
Thank you! This is exactly what I have been looking for
Why do video editing software remove the silent moments and make the narration feel unnatural.
Very comprehensive and quick explanation thanks
You are a Gem
love this video with examples. Writing my first helm chart
This didn't feel like an introduction to me mate. Maybe a bit too fast.
the content is very useful and easy to understand
Thank you very much for all the videos you have made!!!
This is my first video to watch from your channel from last 1 year, Really informative and excellent demonstration. Kudos.
one of the best explanations for helm. You are the best!
Perfect explanation and covered important usage of Helm Usage
Hi Marcel,
thank you for these lessons. They are verry good. Could you present us a more complecated Helm chart? One having more subcharts, backend and frontend (frontend depends on backend) and the backend has external dependencies (postgresql, etc), too. How would you define those dependencies and values? Thank you.
I would personally avoid complex helm charts and encourage to manage distributed systems in a "12 factor pattern" manner, by managing everything in isolated , independant decoupled way. For example, upgrading Postgres should only deploy the Postgres Helm chart and not deploy dependant front-end and backend services. Similarly the front end helm chart should not rely and deploy the backend. I would keep helm charts strictly separated to they can be deployed, managed, upgraded separately
I really appreciate your videos.. it’s really useful..
This is a really excellent video, thank you.
Thank you very much, now it all makes sense on my side. Please don't get tired keeping up this kind of video.
You got it!
This is awesome .. It will be very helpful if you include Skaffold with Helm
I am not sure if you are gonna checkout my comments :), but if you do so , I would request you to cover jenkins and ci/cd pipeline walkthrough.
Done! 💪🏽

What if I have a docker-compose file for multiple things like, Kafka, grafana, Kibana, etc and I want to create Helm chart out of it? Do I need to do something different?
Not really, I would make a folder for each service in the compose file (kafka, grafana, kibana), then start by making YAML files for each in each folder. I.E statefulset.yaml, service.yaml, configmap.yaml, etc.
Then make each of those folders a separate helm chart. I would not combine them all into a single chart.
You have to be mindful that you may need to do maintenance on Kafka, and no need to redeploy all the infrastructure, when only kafka changes. So try keep every product separate if you can.
Hi Marcel... Great explanation ... but 1 feedback... i created the kind cluster .. and created the chart and moved the files as per video.. but i am not able to run the helm template to render the chart.... what am i missing.. i get below error.. "failed to download "example-app" hint running helm repo udpate may help.. but if i try to update repo it wont help me render the chart so where did i go wrong? i made to sure to test with empty values file and with populated values file as per vide both not working for me..
Can you record exactly every step you took (commands) to reproduce it and file an issue on the github repo with detailed steps ? Then I can take a look and see what you may need🙏🏽
Ohhh Man , I was waiting since long to learn helm and finally ,Thanks dude for sharing knowledge in just a cool way 👍
amazing intro to helm. Great content! Thanks
Wow I was shocked at how much value is packed here. Really wonderful tutorial!
Thank you for saving my career :'(
Is it possible to have Video On helm repositories please
Super useful video! Thank you!
Awesome as always
Thanks for sharing
🙏
one doubt how are you ablet install kind and use it
What software you use to make your presentations?
I just took a new position that is heavily investing in cloud infrastructure/resources...so I'm having to upskill in k8s and other related products like Terraform/Harness(drone).
I'm typically reluctant to use resources other than authoritative documents. But coming from a government background where most tech solutions are supported by commercial products and entering the open-source realm...I'm realizing the open-source community's documentation is a few steps behind the development curve.
I found this video and others from you to bridge that gap pretty well and so I thank you because typically I avoid unvetted sources. It's clear you gotta pretty good handle on this stuff and I'm *drumroll vocabulary opportunity* ineffably grateful to have discovered your channel. I'm glad you cover a lot of these related products 'cause it's helping me get up to speed a lot faster than the documentation alone.
