Kubernetes - Services Explained in 15 Minutes!

If you're new to Kubernetes, Services can be one of the most important concepts to understand. In this 15-minute video, we'll give you a crash course on Kubernetes Services and show you how they can help you manage microservices in a Kubernetes cluster. We'll cover the basics of Kubernetes Services, including how to create them, how to map them to pods, and how to use them to manage traffic and load balancing. We'll also discuss different types of Kubernetes Services, including ClusterIP, NodePort, and LoadBalancer, and show you how to choose the right type for your needs. By the end of the video, you'll have a good understanding of Kubernetes Services and be ready to start using them to manage your microservices. Whether you're a developer, sysadmin, or IT professional, this video is for you.

We have various Learning Paths to help you choose your next step and shape your DevOps & Cloud Career.

Check out our learning paths at KodeKloud to get started:

Those new to the Programming and DevOps world often find it challenging to start their journey due to the missing basic prerequisites. For example, issues with setting up a basic lab environment using VirtualBox, problems with networking, or trouble with working with the Linux CLI or text editors like vi editor. Sometimes there are issues with applications - like getting a sample application to work, problems with getting the dependencies to install correctly or trouble with getting a web server to communicate with a database server. Or, at other times, it's working with data formats like JSON or YAML.

So we have identified a gap, and we believe that this is due to missing some of the basic prerequisites, such as knowing the basics of Linux, the basics of tools like VirtualBox, or knowing the basics of the most commonly used applications like Java, Python or NodeJS or web servers like Apache, NGINX etc. As a DevOps or Cloud Engineer, it is crucial to have these basics cleared. And that’s why we are helping you to bridge that gap!

I have never commented on any Youtube 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!

I'VE BEEN WASTING MY TIME READING AND WATCHING ROCKET SCIENTISTS EXPLAIN THIS. GOD BLESS YOU, BROTHER.

[kevinburrowes]

I don't think I have ever seen a more clearer way to explain a tech stack.. ever.. Wow..

[diogoadr]

Wow, mindblowing explanation. Your images help a lot in understanding how things work. Thank you.

[calvinngotho]

Great oration. The most effective 14min tutorial on services. After mauling through tons of text

[manjunathn]

This Kubernetes services tutorial is at the best level😊

[ajsimha]

Easily the best explanation I have heard on k8s service - Mumshad is the best!! Thank you

[yourmoon]

This is the best video explaining K8s Service that I can find so far. More such kind of videos, please.

[CarloL]

Crystal clear explanation! The visuals were very helpful and should be part of official Kubernetes documentation!

[Churchbooklive]

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

[kumarcok]

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!!

[kirinofy]

All tech tuts should be like this. Short, simple, sweet! Thanks man! Also, who dislikes this!?

[SinghAlokkrishna]

Best trainer and systematic explanation.

[anothercrappypianist]

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?

[santoshverma]

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.

[gillianbc]

Excellent video. I do get confused though when the port and target port in an example have the same number.

[utpmahesh]

You have amazing presentation skills + teaching skills
simple, point to it and nailed it .
Thank you.

[screwupkiddy]

Great job. Best video on Youtube explaining how K8s service nodeports work.
