Setup Prometheus Monitoring on Kubernetes using Helm and Prometheus Operator | Part 1

Learn how to setup Prometheus Monitoring and Grafana on Kubernetes cluster using Helm chart for Prometheus Operator

NOTE: Prometheus Operator shown in video is Deprecated. See the git repo for new operator installation and other relevant commands:

Demo Part 1: Setup Prometheus Monitoring with Helm chart for Prometheus Operator (this video)

In the demo I show you the third way. We will easily deploy Prometheus and Grafana using Helm chart for Prometheus Operator and I walk you through the different components, which were created. So that you have a good understanding 💡 of what they are and what they do.

Used versions in the demo:
► helm version: v3.2.1
► prometheus-operator: v0.38.1

In general there are 3 ways to do the setup:
1. Create all the configuration files yourself 👩🏻‍💻
This way is pretty inefficient and it's a lot of effort.
2. Using a Kubernetes Operator 😎
In this option you would go and find an operator for Prometheus and deploy it in the cluster using the configuration files of the operator. It is more efficient.
3. Using Helm chart to deploy the Prometheus Operator 🚀
This is the most efficient way. Prometheus Operator has a Helm chart that is maintained by the Helm community. You can use this Helm chart to deploy the operator.
So, Helm will do the initial setup. Operator will then manage the running Prometheus setup

The most thoughtful, in-depth yet concise explanation of how Prometheus is! Great work!

[purDvotion]

What an amazing video; I especially love the parts where you go beyond just installing like showing what the pods created are actually used for.

Kudos also for the time spent in showing the different Grafana dashboards automatically created!

I have been working on making a monitoring service by myself for Kubernetes worker nodes using Kafka and other setups (which I will suggest for the new learners that don't go on that route). Then one of my friends recommended me to get out of the exhausting approach and go for Prometheus setup with some visualizing tool Grafana, etc. for monitoring service purpose. After a week of searching, I always got the lengthy and exhausting tutorials of creating all lengthy configuration files by yourself which Nana is 100% absolutely right for if you miss one step, it can potentially lose your very precious time. This second method is intuitively very good. I will definitely try it out. Looking forward to good results

[NR-btyz]

Thanks for the help Nana - you are a great teacher!

BTW, here's the current helm command: helm install p1
On WSL2 use: helm install p1 --set

Amazingly clear for operator and Prometheus deployment in minikube
Question:
* why the port-forward is done in deployment for grafana, while it is on pod for prometheus ui
Comments:
* it will be good to state the version u demoed like helm/3.2.4, prometheus-operator/9.1.0, so users can repeat your exercise with the same version when needed
* copy/paste command, it will be good to have related blog (even just git repo) with your each video, so we can copy paste for some commands.
Well done! i like your series, short and clear introduction with demos

[ReneHoffmann]

20:00 you can also create a port-forward for a service, not only a deployment or pod ... i prefer services because its unlikely the service name changes and so its more likely to still works when you reuse the command from your history

[polmaksim]

Dear Nana, please make tutorial, how to setup Istio in Kubernetes, and how all that works. Your tutorials are super clear and professional. Thank you 🙏🏼

[abdulhaqq]

Nana, really learning a lot with these videos related to k8s. Please consider adding tutorials on istio and spinnaker.

[Jam-htky]

love you thank you for keeping your videos up to date! The fact you added new GitHub repo to a non-depricated version amazes me you saved me enough time to leave you a positive comment. Thanks again!

[Haithamn]

Really appreciate your effort (Y). Just saw this one and the theoretical one and they are great and very helpful. Keep the great work (Y)

[abdellatifjerdaoui]

One of the best K8S channel tutorials keep it up

[ankitagarwal]

Finally my 20% project is completed. Please make video specific to grafana and how to write it's ini file like configuring SMTP etc

[reddog]

As always, terrific video! Thank you so much for doing what you do! FYI: The helm chart was renamed and the links have changed.

[Alex-rhyt]

How amazing you are. Everything was clear. I understood the concept. We are lucky you are sharing your knowledge

[TheCkalyanaraman]

Nana, fantastic. The way you are explaining each concept is very much impressive. I am not finding words. Of all I like the way you pronounce each word and how you use your words in explaining these technology. I am a big fan. Thank you so much!

[sakaiamlap]

Been waiting for this. Thank you very much. Love from ph

[gregphares]

Awesome video, super informative. But, just wanted to point out you spelled initiale wrong at 3:08. Do not mean to nit pick. Just though you might want to know... But probably the best Helm/K8s video I have seen yet. Keep the awesome work coming!

[nerdydarkknight]

This is a great channel for all Devops content. Kudos for the effort in creating such an amazing content.

[aireddy]

This is very useful information to understand how to setup Prometheus /Grafana with Kubernetes. Thank you Nana for wonderful videos on your channel.
