Prometheus Hands On | Configure Alerts and Scrape Metrics
Переглядів 1,7 тис.Рік тому
In this video I discuss the core component of the most popular monitoring stack used in kubernetes, prometheus. I review how prometheus interacts with other components and demonstrate how to configure alert rules and new scrape endpoints. I then go into some details on prometheus storage and service discovery with prometheus.
Kubernetes Monitoring | Prometheus Metrics and Exporters
Переглядів 406Рік тому
In this video we discuss the prometheus metric format, how these metrics are exposed to prometheus using exporters and how exporters are made up of collectors. We also provide an example of what a prometheus exporter endpoint looks like and how we can inspect these endpoints for different types of exporters.

Horizontal Pod Autoscaling | Kubernetes
Переглядів 194Рік тому
Note: During the demonstration section I use the 'k' alias for kubectl. To replicate this use 'alias k=kubectl' or simply replace k with kubectl when writing equivalent commands. In this video I discuss and demonstrate how we can use kubernetes to handle varying levels of traffic with the horizontal pod autoscaler.

very good video. very good explanation. Thank you very much.
Thanks for the video.
Hi there. Thanks for the video. What is the difference between a CCM and just using a cluster in AKS? I am trying to understand the benefit of CCMs and why you would use it over just using AKS.
You are great, thank yoi
Hello, in the CKA exam, a node is given an assigned label and asked to deploy on that node, I solved this question with nodeAffinity instead of nodeselector, I wonder if this could be a wrong method to get a successful score.
what about the prometheus-community helm chart not using the operator?
ok the service discovery was good enough for my use case
Very informative, please create video for the statefull set with mongodb
Пасиб за отличное видео, наконец в голове все разложилось по полочкам.
Большое спасибо, мужик, очень хорошо все рассказал.
Thanks man for your demo! Could I know what hardware u used for your FC storage to setup the pv? What are the steps to setup such FC pv for k8s cluster?
This is the most calm tutorial on k8s on UA-cam 😂 where is the subscribe button?
bad i am sorry
Great Content i found it helpful.
The important thing is to show how leases can be used to coordinate a two-replica app to have one active and one passive replica.
thank you! The best tutorial I've seen so far.
Glad you found it useful!
kilershell has texeditor we can from native os but I could not find one during the exam. It would be nice to have texteditter other than vim for making correction
This was a nice one, thank you.
I am not able to read yaml files
At least make the command visible in your video
Give us link how to download Prometheus using helm Give us those commands.. or office document
Hey! The commands can be found here: artifacthub.io/packages/helm/prometheus-community/kube-prometheus-stack
How do i configure the nodes to respect these conditions set, because it just exceeds 100% then times out. I have to come drain it manually. I use EKS
Thank you !! Really well explained
Thank you. This was a clear explanation of the subject. Who creates the StorageClass the Developer or the Admin?
Thanks for keeping it short and up to the point. Got it very well :)
i drained my master node now after uncordon it doesnt work up remain in notready state. how am i to deal it
Thanks for this great video. If I could make a suggestion, please increase your terminal font size for recordings. It's a bit hard to read with a Macbook and hard to distinguish a = from a : even when squinting my eyes :D
Thanks for this helpful video you've provided some great pointers as well useful tips (bash help aliases and functions).
This was great. Thanks! If mul
This is super confusing and misleading. You can't create a PVC without a Storage Class. When a PVC does not specify a storageClassName, the default StorageClass is used
After watching all you tuberss finally found someone who's explaining exactly like i was in want
VERY HELPFUL VEDIO !
Thank you for this video, man. I just got my CKA badge today.
That's awesome man congrats!
What's the reason for a lease to be used by node? For kube API to know the status of the node, can't kubelet of that node just send the requests directly to the API server instead of updating the lease? I can't see how the lease is helpful for nodes. Although I agree with you for distributed case we need leases.
Good question, my understanding is that the main reason for using the lease API is for performance, in particular for larger clusters. You can find a detailed explanation on why leases are now used for node heartbeats here: github.com/kubernetes/enhancements/tree/master/keps/sig-node/589-efficient-node-heartbeats
@@jmmtechnology4539 Thanks for the reply :). Will check that out!!
@@jmmtechnology4539 I did check it out and as you said it's because of the performance. They used to do this earlier but because of etcd going out of storage easily due to these update frequency being just 10s and it has to store this info. They moved away from it by introducing a lease for this. Great read!. Thanks a lot for the resource. Would love if you make more videos on these concepts explaining things internally, why they did what they did. Thanks a lot.
Excellent explanation . Thanks for putting this out
I don't think the controller manager can provision a new node by itself if one dies. I think it has to work with a cloud Kubernetes managed service to do so, like EKS or AKS or GKE.
Hey John, yes you're bang on with that. My apologies for the mistake here. I cover the cloud controller manager in a bit more detail in this video ua-cam.com/video/dWdJMdurWDw/v-deo.html and the information should be accurate.
Hello! Great series of videos, thanks. One reaction to this one. I don't think that Kubernetes by itself can replace a node that has gone down. For that I think it relies on a managed cloud service in which it is embedded, like EKS or AKS or GKE.
Does your keyboard owe you money?
I am currently finishing a cloud devops nano degree, your simple explanation is 100% better than any of the nanodegree's mentors
One of the best content creators, please don't stop making explicit videos. You are life changing
Hey there will you be uploading content to become kubernetes engineer.
Great video, where can I follow you? LinkedIn, Twitter?
WHERE CAN I FIND YOUR ONLINE 👀 (besides here) I just came across your videos!
Hey Anais, thanks for checking out my channel. I’m available on LinkedIn www.linkedin.com/in/jamie-mac-manus
do not do etcdctl snapshot status!!!! it will corrupt your snapshot
21:50 didn't know this cheat. Thank you for sharing
It deserves more views
Is it possible for freshers to take this exam ..? Or prior experience is necessary.
thanks for fabulous content
