A Hypervisor Built on Kubernetes - Cloud Native HCI with Harvester
Рет қаралды 122,159
Күн бұрынRancher released a next generation open source HCI software hypervisor built on Kubernetes that helps you run virtual machines. With Harvester you can create Linux, Windows, or any virtual machine that can be easily scaled and cluster giving your high availability virtual machines with a few clicks. It also gives you a platform to automatically create HA RKE1, RKE2, and K3S Kubernetes clusters with etcd along with the virtual machines it runs on. Now you can run virtual machines and kubernetes on the edge on one machine.

Which hypervisor are you running and are you happy with it?
@MegaDrum1234 2 жыл бұрын
Currently running proxmox as the main Hypervisor, with truenas Core as the NAS - a couple of jails and single VM for redundancy. Thinking of migrating Core to Scale in prerparation for one day maybe scaling back the hardware to a single host once the new Scales KVM is a little more mature with some more features added

I have been running Proxmox for several years now, and am quite happy with the stability and featureset. Proxmox is the backbone for my OPNsense/piHole/Traefik/Authelia router box, and the hypervisor under my media server, game servers, and homelab configuration for testing new apps/toys.

Our corporate application requires Active Directory and all other microservices are running in Kubernetes. I think, bringing this AD VM in harvester gives almost same level of trust and reliability as if it was containerized. Harvester can be used in deployments where you need VMs alongside your Kubernetes workloads for applications which cant be containerized.

Great job on this! For context, I own an MSP. I've been watching Harvester since it was announced and did my first install shortly after. What an amazing product it has become. I will be using this in my business as an offering and a service enabler for my business. For price sensitive companies, this could be an option that gets them into virtualization dirt cheap - no scary VMware cluster pricing. I also have clients that need to build and destroy labs regularly and can use some of their dated hardware for that purpose. So, while the edge is an ideal place to deploy Harvester, its usefulness will make it into the corporate DC. I see this as having massive potential for GSA contracts, too.

I'm old now. My tech stacks tend to be old too. I spun up a KASM machine and came out the other side thinking that all the K3 and Docker stuff might be *great* - but that they - at least to me - lacked the management and handling tools to make them top tier. I came away with how great KASM is, it still fundamentally requires deeper skills to really add anything else to it. So in theory its very expansive, not some much in practice. I watched this video. Really really cool and Tim - you always do a peer level job showing stuff. This to me is the kind of tooling that is needed. It takes what may be great technology - but places the tooling on top that takes it to a new level. I'm still a billion miles off using the new edge stuff, but products like this make me want to spin stuff up, rather than shut stuff down :)

If so can you do another video to explain more the differences? I am fully invested now in Proxmox and I like to know if I can switch (virtual TrueNAS and other services with pass through hardware )
@THEMithrandir09 2 жыл бұрын
Can you maybe do an episode where you talk about all the tools that abstract deploying and running services and how they tie together? Like e.g. running everything on barebones is bad, but giving everything a proxmox VM might also not be ideal. So we use TrueNAS Scale (on top of proxmox) and supply that to harvester which manages kubernetes which then runs Docker(Compose/Swarm), Portainer in-between of it all, and we tie everything together with Traefik to route stuff where it needs to go, etc, etc... There's so many individually complex tools and seemingly infinite configurations to all this, having a nice top-down and/or bottom-up view of all this would be awesome. Maybe something that organizes these technologies into layers or tiers of abstraction or whatever you think is fitting.

If you are into automation, that future might be sooner than you think. Harvester's automation capabilities (thanks to Kubernetes base, iPXE, Harvester's bootstrapping options and the existence of a good official Terraform provider) are way beyond Proxmox's. If you do everything in the UI, then I agree with you, Proxmox is certainly good enough to not try and change it.

I can't envision spinning this up on my home hardware just yet as most of my bare metal is already tied up either in "production" or main lab configurations (like having a big Proxmox hypervisor with tons of RAM and VM's already configured. I think this would be very cool to interconnect remote sites forming your own HA "cloud" without having to use a host like AWS, Linode, etc. Of course it'd only be as reliable as whatever MPLS or connections you have but..... if you integrated that with an SDWAN solution it could happen. I would certainly dig trying to deploy this all up to a Linode cluster or something. See if it is something that could be marketable "as a service" to small businesses. I'll bet there would be a business case for that to be added to the portfolio of smaller firms. -Shane

This sounds like a great solution for a high availability installation of Home Assistant. It would be really interesting to see a comparison of Home Assistant deployed in K3S versus Home Assistant OS. What are the disadvantages of each?
@DJSolitone 2 жыл бұрын
I was into the same kind of thoughts for a long time myself, but the truth is that this is not the proper way to look at it... High availability should not be confused with scalability. Home Assistant can be made resilient through already existing solutions (running it as a docker stack on a dedicated VM for instance), then make the VM highly available by deploying it into a cluster with shared and reliable storage (Proxmox for instance). Kubernetes brings mostly scalability and parallelism of stateless applications, and unfortunately, the concurrency that it brings in the data storage layer (like MQTT queuing or DB persistence), cannot be handled by Home Assistant, which must have exclusive access to its storage layer in order for topic statefulness to be properly addressed. So you can only properly run 1 instance of Home Assistant at a time, but make it Highly Available with clustering and automatic migration of your instance, but you cannot really deploy multiple identical instances of Home Assistant and expect that the events will be properly handled. The same goes for deploying Home Assistant on Docker Swarm and expect to scale the instances. I went through this for a long time and ended up understanding these limitations... Now you still can use Harvester to have this dedicated instance of Home Assistant deploy easily, but it won't be easier (considering the complexity of the network layer in Kubernetes) than playing with straight VMs or baremetal installation of Home Assistant. Hope this helps...

This seem like a sweet deal for bare metal installation skipping Proxmox or whatever hypervisor one does use. I would however have liked to see a scenario where you have several hosts with a bit different configs. E.g. Host A and B with more cores and memory, and host C, D, E with a bit less expensive hardware. Could you in that case create K3S VM:s to all hosts and configure so that only host A and B would be allowed to run "non k3s" VM:s? I'd also like to know if there is a common strategy for scenarios like this, and this goes for Proxmox etc as well I suppose, is it better to create a single k3s VM per host having all resources or should you diversify and have several smaller? Thanks for a great video by the way. I'm running both HyperV and Proxmox and have experience with VMware as well.

This sounds incredible. Since i started my linux sys admin course, i've put some of the fun stuff on hold.. well, python and docker mostly. Looking forward to getting back into it, your video is awesome!! SELinux is another layer of security and could add a some complexity to what your doing with permissions etc, although, from my limited time using it, it seems pretty good. Its not recommended for Ubuntu (which uses apparmor), but CentOS etc uses it. It's an area i need to go back over before exam day using centOS thats for sure... when i was testing it, i wiped apparmor from ubuntu and used SELinux on Ubuntu but the training material didn't recommend it, and i agree lol. I use proxmox as my hypervisor, and i have two nodes, but i generally leave one off as i don't really need the availability. On a side note, I also have written my own qemu script using dmenu (at the moment, these are just local to the desktop, but this could evolve), and these have been transferrable between linux distros. The idea behind this is i've written a master script to deploy the virtual machines, and once deployed, i can run a keyboard shortcut to launch a dmenu script, which has a list of all my qemu virtual machines scripts which were generated by the master script. Might sound weird, but would be straight forward for someone like you - its a one touch quick access to a virtual machine :)

As a side note, if you want to get crazy (for real) how about nested virtualization of Harvester lol... That must be fun... Another awesome video Tim. Thank you so much for your work and dedication to the community ! Thanks to your videos, I am running a Proxmox Cluster on 3 nodes, with a Ceph shared storage for HA of my most important VM. Then on top of that I run a K3s cluster of 6 VM and Rancher with local storage (2 on each Proxmox node). I am in the process of deploying Rook inside the K3s cluster to access the Proxmox Ceph Cluster in order to have reliable PV/PVC for my Kube workloads. The reason being that Longhorn is unfortunately a big failure at the moment IMHO. I've tried hard to get it running for several weeks on much simpler architectures, but it is totally unreliable, most PVC not rebuilding properly at all after a node reboot, even using fast SSD and network. Ceph on another hand is just amazing in terms of stability and usability. I recommend that you give us a tutorial on Ceph, it is such a brilliant project especially the architecture and the thought that went into the CRUSH algorithm.

Super interesting video! I've recently been planning out what software I'd like to run my homelab off of, and this proved to be really thought-provoking in how I want to run everything. After watching this, I went and looked at the TrueNAS SCALE roadmap, and saw that they're going to add KubeVirt and K8s clustering in Bluefin later this year or early next year. This makes me think, rather than doing: A. Proxmox with TrueNAS Core virtualized for NAS and a few Kubernetes instances managed by Rancher B. A bare metal Rancher server and a bare metal Harvester server tied together for Kubernetes goodness I could have two or three SCALE servers clustered together later this year, and from the one platform, have kubernetes and kubernetes clusters for containerized apps, VMs directly in KVM and VMs in kubernetes through KubeVirt, and also a NAS. To me, it seems like easy access to HA across the board: HA containers, HA VMs, distributed storage, and HA for said HA machines by clustering two SCALE servers together. What do you think about this idea?

It is really the next step up from traditional VM / HCI setup, hopefully more to come to the industry, making it an industry-wide adoption

2 Yrs later and I just saw it. COOL - After 2 years, maybe an update of what you've seen about Harvester in new releases? and Hey, Have you tried to use Kasten for backups? maybe a comparison of embedded Backup vs Kasten?

Really thank you for the greate and clear explanation of harvester i am planing to replace my hypervisore with harvester what do you think

I’ve been eyeballing Harvester as a replacement for Proxmox as a single pane of glass spot to manage both k3s and vms, I think it’s time to give it a try! I probably don’t need the 2-layer K3S setup, but it would be really nice to start one initially for K3S right from Harvester, splitting been VMs and physical machines

Ok the nesting here seems a bit unwieldy, but maybe fun ? Maybe there is a super great use case for it, other than 'we did because we could'. Not judging. I don't have much experience with containerization, more a background in virtualisation, but nonetheless curious. Rather than nesting, what would be a good way to go for deploying a working container hosting environment in a 'least nested' way ? Could you do something like Fedora CoreOS on baremetal, and run your orchestration in containers on top of that ? For poops and giggles nesting might be fun, but wouldn't every level just introduce a new set of maintenance concerns: updates/security/networks ? Enjoying the vids!

Thanks! I don't think it's nesting really, it just uses k8s as an orchestration layer.

I just started using proxmox and quite happy with it. But my main goal is kubernetes. Do you think that is a good idea to switch to Harvester??

@Techno Tim: If you compare Proxmox vs Harvester on bare metal. Which hypervisor got the better security / would you rank higher in case of security of installed vms

lab is setup, messing with this now. Question I noticed when you made the cluster you made 3 VMs in 1 pool. the three VMs ran etcd, control-plan, and worker nodes. Is there any reason to break out the pools in the cluster making pool1 be etcd, pool 2 control-plane and pool3 being worknodes?

Ok, but can you use Longhorn with this? Like can you put Harvester on and still access the disk on the box later?
@jaydibble8412 2 жыл бұрын
My question is w Longhorn… besides being local storage, what is supported/recommended? Single drive, multiple drives that Longhorn manages (like sw raid), or he-backed raid? I’ve seen the requirement of 5k+ IOPS, so definitely SSD-based…
@TechnoTim 2 жыл бұрын
As you add drives it seems to add them to longhorn, giving you ha block storage. The interface needs some help making it more clear how storage is managed

@TechnoTim do you have any follow-ups for this software? I remember having a hard time with things being really unstable back in the early 2000s when first trying out SuSe. (Items that were recognized by other OS distros and BSD were never recognized out of the box by SuSe.) I am referencing this because that has been my experience trying to run HarvesterHCI 1.2.1 on a Xeon E3-12667v3 with 32GB ram. I keep getting kernel panics, and the bigger test box that has a dual socket E5-2667v3 and 128GB ram just boots into a kernel panic. both boxes run production services when not being used for this testing, so nothing on them is broken, to my knowledge. I literally caused a kernel panic by simply attempting to upload my very first image iso from my desktop to the Xeon E3 node, on a 10GBase-T network.

Coredns is just a super simple DNS. I have it installed on my pihole, use it as upstream and kubernetes updates it from metallb so I can access each container by name. So not be that surprised to see it outside kubernetes environment
