Docker/kubernetes and VMS are similar in that they are all virtualisation but the similarity kinda end there. Love them or hate them, Each has its own important role in IT infrastructure.

First off, docker itself needs a host operating system to run. Secondly, Docker are containers. Each image is built on a cut down version of the operating system generally to perform one specific task or run one specific application. The environment is preconfigured to work exactly as intended so generally speaking, you don't get the whole "but it works on my machine"

Kubernetes I'm not the most qualified to speak to, but pretty much someone said "ok docker is great but we want redundancy, scalability, etc" and made kubernetes.

A vm is a full virtual machine. You can give it virtual harddisks, virtual network cards, etc. You then install a full operating system on it, could be windows or Linux or whatever you need.

From there you can install docker if that's what you want, or can install specific apps. This is the first difference, is if you install the app compared to a docker container, you need to make sure you have all the prerequisites met, all the correct compatibility, etc. It's up to you to make sure your system is correct for the software.

Another major difference is docker containers are all seen on the network as coming from whatever the host machine's IP is.

Whereas the network views each vm as it's own device on the network, giving each it's own IP (if using dhcp) and allowing things like vlans and things.

As for my setup, I have 3 VMs with docker servers, each with between 20-30 docker containers, 3 VMs running adguard DNS, 1 vm acting as a tailscale entry point, then a few application specific VMs. It's handy just being able to fire up a blank Ubuntu instance to play with me software, and if anything goes wrong just delete the whole machine and start fresh.

Then for storage behind it all, I have a qnap ts453d with 4x 8tb drives.

Then outside my home, I have 2 X Oracle hosted VMs, one hosting about 22 websites and all the stuff they need, one acting as a tunnel into my home services since I'm behind a CGNAT, and then another physical server located in the local data centre running email for a few small businesses and myself

Proxmox is like esxi, it lets you setup virtual machines. So you can fire up a virtual Linux machine and allocate it like 2gb ram and limit it to 2 cores of the CPU or give it the whole lot depending on what you need to do

Having them in a cluster let's them move virtual machines between the physical hardware and have complete copies so if one goes down the next can just start up

It is a little overkill, I'm probably only using about 20% of its resources but it's all for a good cause. I'm currently unable to work due to kidney failure but I'm working towards a transplant. If I do get a transplant and can return to work, being able to say "well this is my home setup and the various things I know how to do" looks a lot better than "I sat on my ass for the last 4 years so I'm very rusty"

This whole setup cost me about $1000aud and uses 65-70w on average

Thanks :D the frame and all parts are self designed and 3d printed... was a fun project

The whole thing runs from just 2 power cables with room for another without adding any extra power cables

This is my little setup at the moment. Each is 8500t CPU, 32gb ram, 2tb nvme and 1tb SATA SSD all running in a proxmox cluster

Edit: also check out Dell micro or the hp... Uh I want to say it's g6 micro? You might need to search for what is actually called

Even running at full speed mine are pretty quiet but I also have 80mm silent low rpm fans blowing air across them too which seems to help

I also recently went through with fresh thermal paste

Not just that, lightning was a similar speed to usb2. It's in their interest to make the pro look like an upgrade rather than highlight just how bad the lightning was really for the consumer

Yeah I'd stay away from Mac too... but seriously most modern laptops can disable any sleep/hibernation on lid close

My go to lately is Lenovo tiny, can pick them up super cheap with 6-12 month warranties, throw in some extra ram, a new drive, haven't had any fail on me yet

HP tomorrow "introducing our new gaming inkjet printer"

Don't forget streets of Sim City that let you drive around too

My thoughts exactly... This might be why nobody is posting there

Been using juicessh for years without any issues

I can't speak for the previous comment but in my case they wanted me to remove 2fa (or pay to keep it) just to log in

I didn't remove it, and I've never been back
