I have never commented on any UA-cam video before but this deserves it. The reason you stand out is because your explanation is absolutely clear and easy to understand, you don't use "Jargon" like others do. Kudos for that. Lastly, keep them coming and thank you for this piece! Cheers!
Awesome. I wonder who has guts to dislike tgis video. Have you produced something better for the community? I guess not. So appreciate what is freely given and well explained
Wow, what a wonderful way to explain about services, Mumshad!! A really appreciate the work that you are doing. I also have couple of your course in Udemy for Ansible, they are wonderful as well, Thanks a lot and keep it up!!
Excellent diagrams and really clearly explained! The main missing piece for an overview is to cover how traffic is distributed for a LoadBalancer type Service. This is an area I really struggled with when trying to wrap my head around k8s networking and the lack of clarity in documentation and instructional videos was a source of frustration for me. (I'm sorry to say your video would also have frustrated me if I didn't already know how it worked, because a) it's so wonderfully produced and b) you tease us at 4:41 by saying you're going to talk about each of the Service types in detail, and then proceed to talk about *only* NodePort. :)) Edit: ah, I just realized this is a snippet from a larger course. Perhaps that does fill in the gaps I mentioned?
Excellent insight , I have ever seen. .Block diagrams are really helpful to get the exact clarity. Please upload much more such video for us. Thank you very much.
Thank you so much sir! watched tons of videos and other references but couldn't understand this part of kubernetes, now after watching this video it crystal clear, and actually I tried it out in my lab and it works like a charm! as always many thanks for sharing this and making it simple to understand...!
Sir, suppose we have different application with the same port running inside the cluster, then how will the end user access any particular application ? Will there be different services to access different applications ? If so kindly explain.
How does the load balancer in services distribute the traffic? considering you are not hitting one specific IP address for load balancer but multiple speicific IP for each pod. i just did not udnerstand that part
What if I don't define a service.yaml ? And I want that app to be accessible only within the Pod , not even pod to pod. Internal to Pod. Not Internal to Cluster.
"In Kubernetes, each Pod has an IP address. A Pod can communicate with another Pod by directly addressing its IP address, but the recommended way is to use Services. A Service is a set of Pods, which can be reached by a single, fixed DNS name or IP address. In reality, most applications on Kubernetes use Services as a way to communicate with each other. Using a Service is much more flexible than addressing another Pod directly, because Pods can be restarted frequently, which means that addressing them by name or IP is a very brittle approach."
so neat and clear..but I was lost the flow of request..where is the listener for nodeport .in which service the listening happens? and why do we need a port in the service ? if request comes to nodeport then will it not get forwarded to target port directly why do we need another port inbwtween? another question is service a service deamon that has listens on its “port”?
Outstanding video, and I mean that! But am I the first person to note that the same sentence gets repeated twice at the 7 minute mark? I started to think I wasn't listening well enough for a moment there, because "it was all starting to sound the same"....
Great video. I have one question, though. If you are doing this on the cloud, how do you know any of the node IP addresses? Won't they be different, depending on what server they are instantiated on? If you are constantly scaling and taking down services that are no longer functioning, the IP address would be very dynamic. Do you look it up on a service directory?
Thanks for the wonderful explanation. I have a question, how do you get the Node IP? I am running kubernetes cluster on my laptop using minikube. When i try to look for the node ip, all i see is the internal IP. The external IP for a node (in my case only the master node) is none. When we are using service with "NodePort", we would hit the application http: : node_port /. But i don't know the node_ip, hence i am unable to hit my application.
This course is for absolute Kubernetes beginners 👉👉: kode.wiki/KubernetesAbsoluteBeginners_YT

We are so glad it helped you understand the concepts clearly. Thanks for watching the video😊😊😊
Nice Explanation. Thank you. It would be great if you can do a video on Ingress Controller as it is the most confusing topic in kubernetes.
Thanks for appreciating our work. You can check out our video on Ingress here: ua-cam.com/video/GhZi4DxaxxE/v-deo.html
Great use of visual illustrations. Hands down the clearest explanation of services in kubernetes!

The person who diliked are dump... This video is awesome
Very well explained in 15 mins.
You are really great. Watching your video was a jump start for me in devops engineering.thanks
@8:25 In NodePort service definition, the only mandatory field is port
Very nice explanation, something I was looking for a long time...Thanks
Impressive work!
Thanks 😊. Please subscribe to the channel and help us grow:)
God gives this channel for all of us!
You are simply awesome.. thank you so much
Very well explained, thank you so much, your one of the best explaining kubernetes
Wow wow. This is truly a great video. Very easy to understand
very good video
in pluralsight, we have one guy reading out of text book. You mark difference to that. Thanks for great explanation.
Welcome🙏. All our videos are simple and easy to understand.
Excellent tutorial. Simplified a complicated topic
Hello Mumshad, could you please share complete course details to learn kubernetes and go for certification
before I had doubt its cleard from this VD its helped me lot. great ...
Bro, I absolutely love this video. Thanks.
Omg thats what I've been looking for, great explanation and very understandable, can't say it about other tutorials I've previously seen
Great !!! Thanks
God bless you sir, Amazing work .
Thank you, lots of love and prayer for you..
Very clear explanation! Thank You!
Clear cut explanation... 👏
Sir, suppose we have different application with the same port running inside the cluster, then how will the end user access any particular application ?
Will there be different services to access different applications ? If so kindly explain.
Great oration. The most effective 14min tutorial on services. After mauling through tons of text
Thanks for your kind words! Means a lot to us. 🙏🙏🙏
The best explanation. Thanks
Awesome! Nice Explanation. Thank you.
what is the next video to this one? I need know more about the service of load balance ?
How does the load balancer in services distribute the traffic? considering you are not hitting one specific IP address for load balancer but multiple speicific IP for each pod. i just did not udnerstand that part
Perfect video, thank you so much!
Thanks for the great explanation!
It's highly appreciated!
Great explanation, thanks!
Really great explanation. But what about cluster IP & LB concept ? pls share
thanks for quick response. i have already subs. Pls post more video in youtube instead of udemy etc. It helps all.
but how do i know which node to hit if the pods are only runnning in a subset of the nodes?
Very well explained, thanks
Thank you sir, awesome explanation
Thanks a lot , very informative.
What if I don't define a service.yaml ? And I want that app to be accessible only within the Pod , not even pod to pod. Internal to Pod. Not Internal to Cluster.
"In Kubernetes, each Pod has an IP address. A Pod can communicate with another Pod by directly addressing its IP address, but the recommended way is to use Services. A Service is a set of Pods, which can be reached by a single, fixed DNS name or IP address.
In reality, most applications on Kubernetes use Services as a way to communicate with each other. Using a Service is much more flexible than addressing another Pod directly, because Pods can be restarted frequently, which means that addressing them by name or IP is a very brittle approach."
Mashallah great explanation and slides bro :)
so neat and clear..but I was lost the flow of request..where is the listener for nodeport .in which service the listening happens? and why do we need a port in the service ? if request comes to nodeport then will it not get forwarded to target port directly why do we need another port inbwtween? another question is service a service deamon that has listens on its “port”?
NodePort help you to expose your traffic/client request outside world(outside of your k8s cluster)
Wow, excellent explanations 🙏
Outstanding video, and I mean that! But am I the first person to note that the same sentence gets repeated twice at the 7 minute mark? I started to think I wasn't listening well enough for a moment there, because "it was all starting to sound the same"....
Question: How is the ClusterIP assigned dynamically when we create a Service?
I hope we can't do any thing for cluster ip kubernetes itself create and use for Internal pods communication
Great video.
I have one question, though.
If you are doing this on the cloud, how do you know any of the node IP addresses? Won't they be different, depending on what server they are instantiated on? If you are constantly scaling and taking down services that are no longer functioning, the IP address would be very dynamic.
Do you look it up on a service directory?
nicely explained. thanks
Great explanation.
Awesome explanation
Very nice! Keep it up!
nice video, thank you!
You know , you are Great
acording to video, target port and port must same value ????
Hi... thanks for this awesome video. please explain what is Kubernets proxy purpose (kubectl proxy)
Great teacher. Keep up the good work. Hopefully I can sign up for one of your classes on udemy soon.
Pretty cool explanation way
Awesome!!!
share the link for service yaml
great video
awesome
superbb..
Double thumbs-up
I think the first thing explained in this video should be 'A pod is ...'.
Where is kubernetes development controller explained? Please share video link for the same.
great
Super bro, nice presentation where do you live bro..
Love it
How did you find out your 192.168.1.2 (node IP?)?
I know the node IP because I set it up. If you didn't set it up use the "ip addr show" command.
👍nice
Node Port:3:23,
Wow
Thanks for the wonderful explanation. I have a question, how do you get the Node IP? I am running kubernetes cluster on my laptop using minikube. When i try to look for the node ip, all i see is the internal IP. The external IP for a node (in my case only the master node) is none. When we are using service with "NodePort", we would hit the application http: : node_port /. But i don't know the node_ip, hence i am unable to hit my application.
hey, did you find the answer to this? how to get the external IP?
awesome
one of the best explanation of the services, Thanks
Excellent video. I do get confused though when the port and target port in an example have the same number.
Thanks a ton! Your support makes all the difference 💙
