Hey, First of all thanks for these great videos. I have a question for what you explained around 10:29 minutes wherein you mentioned the connection between a PVC config and the Pod config wherein the PVC is being referred to. I found one point missing here. How is the PVC config you showed is connected to the PV. Is it that when the storageClassName attribute is defined as "manual" the PVC is considered to be claiming it's backed storage from a PV ? Because later on in the video when you explain how a PVC is connected to a SC you clarified that the storageClassName is set to the name of the Storage Class. Appreciate if you could clarify this part or if I am missing something here. Thanks!
Alright, so I might be answering myself on the above question and also for those who might be having the same question when going through this video. As per the documentation (kubernetes.io/docs/tasks/configure-pod-container/configure-persistent-volume-storage/) it does appear that the storageClassName needs to be defined even when a PVC wants a claim from a PV instead of a SC, and the value of the storageClassName needs to be "manual". Hopefully I understood it right now.
Also when at time 20:11 you mention that we add additional attribute named storageClassName in the PVC, it actually is not an additional attribute per what I wrote above but instead a name which is not the string "manual".
@TechWorld with Nana Is that possible? To mount a PVC volume in a Linux VM, Because I need to share the same common storage volume for both VM and pod.
Done thanks Types of volumes: 1. Persistent volumes 2. Persistent volume claim 3. Storage class When a pod is restarted, storage is deleted. Data persistence needs to be configured for applications that need storage between pod restarts. But you don’t know which node your pod will be restarted on, so the storage must be accessible from all nodes. Storage also needs to survive entire k8s cluster crashes/restarts Persistent volume is a kubernetes resource (like RAM), gets created using yml file 2:30 The actual storage of the volume is taken from either local storage, external nfs servers, cloud storage 4:30 defining which storage backend to use for a PersistentVolume Local storage has a nodeAffinity attribute PersistentVolumes dont belong to a namespace, accessible to whole cluster 7:15 local vs remote volume types, but local volumes are not really persistent. They are specific to one node, and do not survive a cluster crash Persistent volume objects should be created before the pods that depend on them 9:30 A persistent volume claim is a k8s object used by applications to claim the persistent volume 10:20 persistent volume claim is then used in the pod specification under the volumes: attribute While persistent volumes are available in all namespaces, persistent volume claim must be in the same namespace as the pod using it 11:30 volume is mounted into the pod and also into the container in the pod that wants to use it 13:45 configmap and secret volume types 17:15 storage class
Being a Dyslexic and a visual person, these video's are invaluable to me. It would take 10 times longer to learn this if I had to actually read the manual from start to end. Thank you so much for doing this, it mean more to me then you will know.
IMHO, Nana's explanations and her familiarity with the relationships between the parts in k8s are the best. --- Disclosure: I worked at Google for five years and I have been hanging out in the k8s community since 2016.
Hi Nana, I just wanted to take a moment to thank you for the fantastic content you’ve been creating around Kubernetes! Your videos have been incredibly helpful, and they’ve played a big role in deepening my understanding of container orchestration and the ecosystem surrounding it. I especially appreciate how you break down complex concepts into digestible and actionable insights. If I may suggest a topic for a future video, I’d love to see you dive into Rook/Ceph. It’s such a powerful storage solution for Kubernetes, and I think many in the community would benefit from your take on how to set it up and use it effectively. Thanks again for all your hard work, and I’m looking forward to your next video!
I've been working with k8s for more than 1 year now at a large software corporation and your videos have tidied up what I've learned during this time and made things much clear. It's great how systematically you proceed in these videos. Keep up the awesome work Nana!
Once again, youve taken a concept that I have been struggling with and entirely cleared it up. Not just that though, you've provided a visual representation that will stick around every time i approach this topic. If only kubernetes made such visual effort in their docs.
This is really wonderful and usefull session for us. Because i have gone through more videos, I did not understand, , I an very clear PV,PVC ,Storage, ConfigMap and secrets.With in 20 mins i got entire conepts about Storage compoents in K8s.
This is the second time I get to warch one of your k8s subject explanations and I am very impressed. The structure of the explanation is very well made. It always seem to build all the necessary "conceptual blocks" in advance and then creates a big picture out of it. How often have I read or watched tutorials that were just missing one or two crucial bits of info to make things truly clear ? Your work nails all these details every time, amazing ! It may not be how every one likes things being explained to them, but it really does it for me. Congrats and keep up the great work !
There's a reason why this video has hundreds of likes and not a single thumbs down. Some clown will change that eventually, but let the record show that as of now it's 429 up, 0 down. Trolls won't be able to change that fact tomorrow. Kudos to you, Nana. This was awesome stuff and a timely tutorial for yours truly.
Such positive feedbacks like yours and the awesome thumbs ratio is really awesome and motivates to keep creating these videos for you, thank you Brian! 🙂
I wish I have watched this video before my interview as I have failed in answering storage classes... Thanks Nana, I will stay tuned for future videos.
Thank you, Nana!! Your videos have helped me a lot in learning k8s. I keep watching these videos over and over again and it gradually makes sense when using them on my job.
Great video! Data management is probably the biggest challenge in microservice driven architectures which are often implemented in k8s infrastructures. Volumes remaining "synched" with the orchestrator scheduler specially for DBs seems like a tabu for many instructors out there while in this video your just "grab the bull by its horns". Looking forward for those demos thank you.
Thank you so much 🙏Really appreciate it. You're absolutely right. Persistence with containers, is a challenging topic. I have discussed with some k8s engineers that have said they refuse to deploy any stateful application in k8s cluster. So what they do is create Deployments in k8s and host Databases outside the cluster the traditional way. I think there are advantages and disadvantages for both cases. I will try to cover these in the demo videos. Thanks again for your comment!
This video is so great. Your explanation is totally on the point. The hard part is understanding the relationship among these components and having a general view of what they do, when to use and why we need them, your job is excellent in doing so.
Very much impressed Nana with your explanation. I sincerely request you to make more and more videos on k8s covering all of its topics along with real time use cases by showing their practical implementation right from scratch.
Nana thanks for every single video's which you have posted, i went through them and in last 3 days my concepts regarding K8s and docker got improved. :)
Very helpful video, When it comes to persistence basic Kubernetes videos do not cover it. But somehow this video summarised all the required information perfectly. And the YAML files you have provided are just great. Looking forward to more videos.
Fantastic, the way you explain in such a simple way is really helping a lot to understand each topic completely. And sharing such a well created video free is really the best thing happened for k8s professionals like us.
I wonder who the 16 people are who gave a thumbs down. I really appreciate you spending so much time in creating this video!! If you do make a different video for the different volume mount types, please please add a link in the description, so that we can go ahead and watch that as well.
Very well presented! I was scratching my head on how to put my ELK cluster currently running on VMs into my newly built Kubernetes cluster. This video really is a good start. Vielen Dank :-)
Wow that has helped me a lot. Reading text and books was a bit overwhelming, but these videos are awesome. I am struggling to understand how to operate RabbitMQ in kubernetes. I can get simple Docker RabbitMQ server instances to run, but it's not obvious how this works in kubernetes, when pods die and restart etc. Surely the persistent messages are lost, unless some form of Persistent volume is used.
Thanks Jules 🙂 I haven't used RabbitMQ, but it really depends on 1. what storage you use (local, cloud) 2. how you install RabbitMQ (helm chart, own configFile). But generally speaking, you would first decide what storage you want. and then in the configuration file you would configure the storageClass of that storage or create PV and PVC manually. Does this help?
@@TechWorldwithNana Hi Yes. That sort of makes sense. I have got RabbitMQ up and running on Google Kubernetes Engine, as they offer a RabbitMQ K8 App on their marketplace, it just needs a patch to expose a Service for none K8 cluster clients. But the RabbitMQ installation does not obviously make any StorageClass, persistent Volume claim, unless it is hidden in the Apps installs. I will need to study any additional volume or disk claims on my cluster.
@@juleswombat5309 If you don't see any PV or PVC created for RabbitMQ creation than it probably doesn't create them (at least not by default). You can check in the pod details what volume it uses. My guess is maybe an emptyDir to store temporary data. You can also check, whether you can configure a storageClass parameter for the RabbitMQ app from GKE marketplace.
Thnks you so much for making us to comprehend the kubernetes topics. iam new to this chanel,what a explanation got crsip idea about kubernetes storages
It's just amazing how you're able to explain everything that i need to know about this subject so well. Thank you so much, congrats for the great content
thanks alot @TechWorldWithNana for creating this amazing series however its a request please make a video on practicle examples of pv and statefullset as you mentioned in the video it will be huge help for us
Great video, What I missed in a high level manner only is that how the admins configure the storage class/PV with the actual physical storage be it cloud or local.
Thank you for preparing such an amazing video for dummies like us. I have one conceptual question, as I understood one pvc can be bound to 1 pv only and that why we define our yaml both for pv and pvc but I want to know the logical reason why is it that 1 pvc can only be bound to 1 pv and not more? what stops it from doing so logically and conceptually?
Insanely good straight-to-the-point explanation on how storage works on K8s; also the description containing the timestamps and all the other information is about 👌 Already subscribed, I’ll make sure to share this goodness :)
Thanks Nicolas 🙂 In my last video (ruclips.net/video/JGtJj_nAA2s/видео.html) you can see small part of the volumes in practice, namely: dynamically creating volumes on a cloud storage using storageClass. Hope this will be interesting for you
Excellent again Nana. you are simply amazing. i do have one question. where can i ask?" One quick question: Storage class created for each storage provider with a unique-name needs to be created by admin and developper need to write PVC request volume from that. if we need more space, how Storage Provider works?"
Thank you so much. To your question: You have to configure your storage provider independent from k8s before you can use it in your cluster through StorageClass and PV. So for example, you would go and get 200GB storage capacity on your company's NFS servers. Once you have that, you can use it for PV in k8s. Is that understandable?
this is nice. So to clearification - lets say you have 2 PV (pv1 and pv2) ..you delete the pod and redeploy that pod. How does it know which pv1 or pv2 it will use again. .....say it was on PV1...will it use pv2 when we deploy again?

Whenever I have blind spot of Kubernetes, I search through this channel. And it never let me down.
I agree!!!
totally agree, and execellent work from Nana
Done thanks
Types of volumes:
1. Persistent volumes
2. Persistent volume claim
3. Storage class
When a pod is restarted, storage is deleted. Data persistence needs to be configured for applications that need storage between pod restarts. But you don’t know which node your pod will be restarted on, so the storage must be accessible from all nodes. Storage also needs to survive entire k8s cluster crashes/restarts
Persistent volume is a kubernetes resource (like RAM), gets created using yml file
2:30
The actual storage of the volume is taken from either local storage, external nfs servers, cloud storage
4:30 defining which storage backend to use for a PersistentVolume
Local storage has a nodeAffinity attribute
PersistentVolumes dont belong to a namespace, accessible to whole cluster
7:15 local vs remote volume types, but local volumes are not really persistent. They are specific to one node, and do not survive a cluster crash
Persistent volume objects should be created before the pods that depend on them
9:30 A persistent volume claim is a k8s object used by applications to claim the persistent volume
10:20 persistent volume claim is then used in the pod specification under the volumes: attribute
While persistent volumes are available in all namespaces, persistent volume claim must be in the same namespace as the pod using it
11:30 volume is mounted into the pod and also into the container in the pod that wants to use it
13:45 configmap and secret volume types
17:15 storage class
thanks

Pv, pvc and storage class never seen any where explained this much neat and clearly 10000 thanks to nana…keep taught us
Freshly joined a team working on a project with k8s and found this channel greatly deciphers the mysterious YAMLs in the codebase!
I love your english. Not a verbose wordy jargon native english. Clear and perfect
IMHO, Nana's explanations and her familiarity with the relationships between the parts in k8s are the best.

Disclosure: I worked at Google for five years and I have been hanging out in the k8s community since 2016.
It is always amazing to watch your videos. You make every concept crystal clear.

Watching this + reading the docs really clarifies PV and PVC
This was one of the best 20 mins I have ever spent learning something. Very clear explanation with visuals. Thanks :)
best definition of k8s pv, pvc i have found anywhere online

hi oran
I have only one thing to say... "God bless you!"
Ohh Nana, you are fantabulous. Your videos are so segmented to hit the tiniest details. Great work!. All my IT goons must follow you ASAP!
Nana, these lectures are pure gold, thanks again.
One of the best series of presentations on Kubernetes on the net. Great clarity and depth. Very much appreciated, thank you!
Your a great trainer , never explained this much deeper on PV , PVC , and storage class
this video is one of my favorite, volume explained in a vgood way, Thanks a lot , I keep watching it every time I need to do something with volumes

Hii nana, you are best teacher to me. I ll follow all your videos. Can you made videos on Terraform? It really helpful to people a lot
Perfectly understood in the first shot itself , Thank you Nana :)
Excellent video, thanks Nana - you explain how and for me, most importantly why there are so many abstraction layers/object types for k8s storage.
Greatly explained Nana. Appreciated...
Excellent video to understand K8S Volumes!! Thank you very much!...
Now I understand everything about Kubernetes. Great job, thanks!
SUBSCRIBED. LIKED. SHARED.
Thank you 😊
Thank you Nana. nicely explained and made it so simple

A small request, could you please give a session on NFS as well?
Thanks for your beautiful explaination.please make and upload more videos on pod security policy and service discovery in kubernetes.
Hi Mohammed, I took a note of your suggestions and thank you glad you liked the video :)
Nice video......clear.....it will be interesting to understand how CSI Work with PV
Really well done. This has been a slippery concept for me for a while, but this was well-articulated.
Well Done 👍🏽 ... You explained things in this video clearly ... I’ll be checking out more of your videos going forward
Clear clean explanation. your presentations simply awesome. i can understand how much efforts your put for presentations. keep it good stuff.

So for example, you would go and get 200GB storage capacity on your company's NFS servers. Once you have that, you can use it for PV in k8s. Is that understandable?
@@TechWorldwithNana Thanks Nana. i got it. again thanks for replying to my question. appreciate.
Hi Nana.. This channel is really good. Can you do a video on how to do a complete CICD in kubernetes
Hi Rakesh, thanks for your suggestion. I took a note of it and will consider it for my future videos!
this is nice. So to clearification - lets say you have 2 PV (pv1 and pv2) ..you delete the pod and redeploy that pod. How does it know which pv1 or pv2 it will use again. .....say it was on PV1...will it use pv2 when we deploy again?
Very useful and I got a clear understanding. Excellent one. Thanks for providing such videos for us.
Clear explanation, great effort , thanks very much
good job. Actually - Amazing. Thank you. As a previous reviewer said: it helped me gain an intuitive sense of volumes!!!
Thank you 😊
Thank you so much.. waiting for following video to understand volume type and demo
I appreciate your positive feedback 🙏
Is the following video available?
