I didn't have a clue what you went over on this video (b/c im new to all of this myself) but it looks very interesting. Keep making these type of videos because you seem to be more knowledgeable than what you put yourself to be.

Your production values are always great. I haven’t figured out a need for Kubernetes yet. Maybe one day.

The things you did are good for a first setup but i have some tips: - make use of projects to add minecraft servers. In a project configuration you can tell how much resources a project may take. We have projects for our buildserver and management seperate so you can give for example someone access to the buildserver project but not to it's management project. - do for example the minecraft server in it's own namespace. If you do that it becomes easier to filter for it.

Your videos are getting ready high quality! I really enjoyed watching this

I bought 4 of the M75Qs and loved them so much I bought two more and then four M75Q G2s for the new production cluster. Four of them are as powerful as my single Epyc 7402p that has 180W TDP, so they actually use less power and cost much less! I use them for kubernetes clusters that I deploy with PXE booting using my unify/synology setup and configure with ansible.

Thanks for this very hands on video. I stumbled on to K0S which is "supposedly" even lighter than K3S and just as easy to use.

Thanks for the demo and info, have a great day

Setting up the storage as RWO was totally right. The only thing you got wrong was that you'll need to create a StatefulSet(sts) instead of a Deployment. That's because with a StatefulSet a pod replica is bound to a PVC. So when you do a rollout restart it will wait for the PVC to be unmounted before starting the new container. By setting the PVC to rwx you'll also lose a lot of performance, because it will share the volume via NFS...

@HardwareHaven

Жыл бұрын

Ah, thanks! Appreciate the help!

@danilfun

Жыл бұрын

With stateful sets there is a different issue: you _have to_ use several replicas. K8s guarantees that in a stateful set there will never be 2 pods pointing to the same PVC. So if a node dies, k8s will never replace the old pod, because it can't successfully terminate it. This is fine if your app natively supports clustering. For example, if you can run 3 replicas of minecraft server, each with its own unique disk storage, but with synchronized state, so if one of them dies, the remaining 2 will continue handling requests, and clients won't even notice. Databases usually have support for this mode. I'm not sure if minecraft server does. For stateful workloads that don't support clustering natively I'm yet to figure out something better than a deployment with a single replica.

I just built this in my homelab! Ended up with 3 master + 2 agent nodes on HP 705 G3 machines i got for super cheap.

it would be cool if you made a proxmox cluster on these, and combine their resources, to run one VM

Hello, I've just made a corosync and pacemaker cluster between two debian 12 machines and I want to install CasaOS on the cluster so the load is balanced between the machines. Is it possible to install CasaOS on the cluster and if it is, how?

need a workflow for k8s on baremetal and with out longhorn.

do you know if its also possible to do the same but with docker installed on the pcs ? so the container has linux

Well, I'm currently training for the RHCE and the whole thing is about ansible. This could be an application for my elitedesk minis once I pass the exam.

Many Nodes R/W can become a problem if the node is not completely down, but still running and just the network is disconnected. Then MC on the disconnected Node could still write into the volume, but also another MC pod would try to write there and in the end you would have data corruption. That's one of the bigger problems with Kubernetes and HA with persistent services :)

Hey, I'd like to do a K3S HA cluster between different NATs (mine and my grandparent's house), since the most risky part is the internet connection. I'm considering using Tailscale for the communication between the nodes and then have 1 node run my app at all times, and when that starts it tells cloudflare to set the A record to my current IP. Is this a good or flawed plan?

just wanna say that rook is probably not the best choice for most use cases. It's pretty slow and pretty dang bad on 1GiB/s. I'd much rather use drbd with the piraeus operator that does reads locally. So you'll get full NVMe speeds on reads and really fast writes thanks to drbd9. It's also very fault tolerant and survives a node drain unlike Longhorn...

you want regular desktop cases in terms of refurbs - more expand-ability and ease of use - refurb pc are value kings - no question - having a reg sized case will aloow you to add better networking and gpu options and stay away largely from vendor proprietary parts - you might use a bit more power - that is totally ok since you will probably have more better cpu and ram - biz wants cluster tech for HA but also since they can scale out easily - just add a node or two

I get it, but you’re still making assumptions. You’re assuming that people prefer expandability and performance over size and efficiency. In this instance, I 100% prefer the 1L cases over something larger and I don’t really care for >1Gbps since I’m not transferring a ton of data. So buying bulkier machines would’ve made no sense. And I don’t think I’m a unicorn. I think you could easily have said, “I would prefer and probably get larger form factors for the expandability and higher clocked CPUs” and been 100% correct. Just stop making blanket statements based on your opinion/needs/use case.
