Cloud Native Distributed Storage in Kubernetes with Longhorn

Storage in Kubernetes is hard, complicated, and messy. Configuring volumes, mounts, and persistent volumes claims and getting it right can be a challenge. It's also challenging to manage that storage and replicate it across all your Kubernetes clusters. It's also been very challenging to do this on bare metal, outside of a cloud provider. That's where Longhorn comes. Longhorn is an open source, a CNCF distributed block storage system for Kubernetes. It comes with a UI, backups, snapshots, and cluster disaster recovery and it does all this with or without Rancher. Rancher is NOT a requirement.

Thank you for watching!

How are you managing storage in kubernetes?

I tried OpenEBS, NFS, StorageOS, LocalProvisioner and they were ALL a pain to deploy and finicky to use. But so far Longhorn has been simple.
The dedicated UI helps a ton whenever I allocate a pvc and can't the pod can't attach to the PV.

Your Video also showed other features that I never explored like backups and snapshots. Keep up the great content! You are now one of my favorite channels. Subbed with Notification Bell

Dude, how can I give two thumbs up!? I was trying to solve this volumes issues for a while, and then you came and did it for me, again.
Thank you so much!!!

Ahhhh yes! My favorite time of the week, when Techno Tim releases a new vid.

3 years laters still top TechnoTim, awesome thanks for your contents

[jaysistar]

Thanks! A storage node manager, redundancy, and backups were exactly what I was looking to find. It's a great plus that it has a nice UI, too.

What a coincidence... I was just reading longhorn docs to use in our prod, and you just made it easier 😁 thanks

I have longhorn installed on my 12 node pi4 cluster with a few of my nodes with extra SSD storage. Works great!

[goldenmunky]

This is freakin amazing! Thank you SO much for this video!

Tim : "Thanks ahead of time for the likes"
Me : Instantly likes video.

[hoangphuloctruong]

Very thank you TIm, you provided me a new approach to the storage in k8s

[migliorista]

This THE solution! Nothing better. Even moving to another server or creating clusters across servers and nodes! This is the solutions someone doesn't know are there and save lives of Systems Engineers on a daily basis ahahah

Well... I'm certain it is pronounced Maria and not Maria

[stompreaper]

Thanks Tim. This was very timely. I was just starting think about the issue.

[georgioskatsanakis]

man happy I found your channel, planning for homelab for my projects, and you made my life easier.

[acetin]

very high quality content together with the documentation site, amazing work!

[dimaa]

fine, you convinced me to use rancher with k3s.

[blaiseutube]

Thank you!!
I love k3s and looking forward to longhorn

[bisdak]

More Rancher how to's please. great job on this.
