Thanks for stopping by

[@edgeuplink]

Good luck with your channel ! Good insight

[@RahulWagh]

I appreciate it!

[@mathewkargarzadeh3158]

Thanks Rahul !! for your wonderful tutorial on persistent volume in Kubernetes. I was puzzled why in the pod Yaml. you referred to it as "Kind: pod" not "kind: Deployment". Thanks.Mat.

[@RahulWagh]

Hope your query got answered. let me know if you still have any question

I think the mount path in the deployment file is wrong. it should be the container path that need to be mounted to the volume not the volume it self. correct me if I am wrong.

[@DEEPAKKUMAR-wk5pk]

Great explanation with example.

[@RahulWagh]

Glad you liked it

[@mulshiwaters5312]

Good explanation
As PV is K8s cluster resource I assume PV and PVC are the only way to attach volume to POD. then container/s inside POD can mount the same volume to container.
Query 1: If I have two replicas for my App POD, one Replicata set on NODE1 and another Replica Set on NODE2 .Does both Replica use the same PV and PVC to attach volume to both PODs ?
Query 2 : If I want to mount external storage like NAS directly to container inside POD , can I do this and if yes what would happen if POD dies and recreated ? how I can automate NAS volume mount to Container in case POD rebooted or dies ?

[@devendrasinghrathore9423]

Very nicely explained 👌🏼

[@manishkumar-hg1xh]

Very nice and explained well

[@jonforero]

Thanks for the explanation!!
I wanna Know something, It's possible to bound the same PV to two different PVC that are in diferent namespaces?

[@anandkdurgam]

Thanks Rahul, it looks great esp the working demo. Keep it up.
I have question though - spring boot application hosted and able to run it, but would you be able to share an io operation to it?

[@RahulWagh]

Hi @Anad Durgam thanks for your comment.
Can you elaborate more on IO operation? I want to understand what you are trying to achieve, so that i can answer your question in better way
//Rahul

[@anandkdurgam]

Thanks Rahul for your response. Question was how to create a folder or a file to the configured path using PV/PVC.

[@davidjhons2549]

@RahulWagh
And all data generating by that running pod will be available on "home/vagrant/storage" location on our local system and we can access that data,
am i right?

[@RahulWagh]

Yes that’s right

[@vaishnavikale713]

Very great explanation!! Thank you

[@RahulWagh]

Glad you enjoyed it! stay tuned for more

[@chrisnavarro5122]

Thanks Sir for the video! how about existing POD can we bind or integrate the PC and PVC? I'm trying this on AWX via minikuibe?

[@RahulWagh]

Yes you can bound it you need to edit the POD yaml configuraiton and mention the PV and PVC

[@vijayaaiella9287]

Excellent Rahul ......

[@JoseCastro-ql1yl]

Very good!!

[@sanzayy]

Thanks for demo.

[@RahulWagh]

[@ameyabhyankar4944]

Thanks for the video. I am getting following error after deploying the pod = error: the server doesn't have a resource type "jhooq-pod-with-pvc"
Any thoughts how to fix this issue? I am using minikube. Thanks.

[@omarferrin3404]

How do I access a microservice in kubernetes in virtual machines of google cloud from my computer?

[@omarferrin3404]

I expose it, but apache doesn't load on the website

[@RahulWagh]

Hi Omar I would be glad to answer your question but it would really nice if you could add more details to your question -
1. How you are trying to expose your service - NodePort, ClusterIp or LoadBalancer?
2. But i think you could refer to this clip where i exposed the service from google cloud on external ip - ruclips.net/video/ejwiMFJETdQ/видео.html
Let me know if you still face any issue, I would be glad to help
