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.

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 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 :)

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.

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?
@DJSolitone2 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...

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.

If you are into automation, that future might be sooner than you think.

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 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 :)

OKD also doesn't have to put kubernetes in VMs on kubernetes. It just exists as both from the start. Also, your containers and VMs share the same storage pool with Rook CEPH. Looks like with Harvester you would be setting up longhorn on top of longhorn, replicating your storage on top of replicated storage...

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!

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?

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?

harvester does look promising, but I unfortunately could not get grafana/prometheus working. I enabled them but just got errors that they were not available in the console.

more importantly, is that a Grafana dashboard on your watch :-)

The hypervisor is *below* k8s. Just in terms of layering, bottom up: hardware, host kernel, hypervisor, guest kernel, guest apps. K8s is running at the same level as the guests, orchestrating them. I hate to criticize this otherwise good video, but I’m seeing folks here use the wrong terminology.

No worries and thank you for the feedback! I really appreciate it and I didn't take this as criticism!

Do you prefer this over PVE? Just curious. I love PVE but always willing to give other things a chance.

I like the idea of a single solution for both VMs and containers. You mention that it needs low system requirements though today I see it needs at least 64GB memory, 16 cpu cores (!) and 300GB storage for production and when installing it it seems that it consumes 50% of the 12 CPU cores all the time without even running any VM… also it takes too much time to become in ready state which is a no go for prod. Still today seems like harvester is not giving an impression of being production ready.

Hi Techno-Tim, have been watching your excellent videos and subscribed after the first one... Thank you so much for your valuable work. I've got a question could you do an overview video on a realistic network, say three layered private networks (onion peeled) with deeply secured inside to on-the-edge nodes/docker instances or VMs in it? Such a video will bring your other videos into context...

Cant get a cluster running with the ubuntu cloud images. BTW i am running Harvester as a nested VM on top of Unraid, cause i dont have another machine available. Nested virtualization features are enabled in BIOS, unraid and in the VM settings. VM shows VMX as available. I can start a normal Ubuntu VM installation, but not the minimal cloud images.

100 ppl will ask: 1. is this better than proxmox? 2. how to do GPU passthrough? 3. can I install rancher with K3s in Harvester also use the same Rancher to manage the Harvester? 4. why traefik?

Hi Tim, love your content, I recently tried Harvester myself but couldn't get it to detect my NUCs NICs, so ended up going back to Ubuntu with Rancher. are you aware of a way to add some drivers to the harvest distro? maybe editing the iso or re-compiling the kernel or something?
@TechnoTim2 жыл бұрын
I am not aware but I would open an issue on their github for more nic support!

ok I've watched this video several times as Harvester is really interesting. Think I'm going to install it on one of my tiny/mini units. You said it may not be made to replace a hypervisor, but curious how long you've been running it and has it been able to be a replacement for Proxmox or xcp-ng in a homelab
