1st: Virtualization
2nd: Firewalls and networking
3rd: Containers, Docker, (Podman) and LXC, (Incus)
4th: All the above leads onto Hypervisors
5th: Which leads you to Kubernetes
The first three require minimal hardware. Once you've got the hang of the them, it's time to get serious with a dedicated machine with greater hardware resources to run a Hypervisor.
Kubernetes, all that built in redundancy makes it hungry beast. Enough to get you looking for one or more those big old servers that homelabers love.
I had to upvote this because I like the added "progression path analysis" given. Everything checks out so far from my personal experience.
However I have not yet delved into kubernetes yet.
Could the poster of this reply elaborate (briefly is fine) what some advantages are with Kubrn8s? You mention redundancy. From my completely inadequate understanding of kuber, you can cluster together the resources of different individual systems? Like how truenas can use all the storage of different sized drives to form one pool that can be managed as 1 resource? This of course would just be an example of what it does in concept?
So theoretically, one can sort of network a cluster of old PC's to make a really decent, redundant "server" that shares the workload?
Hop over to the Youtube channel "Jim's Garage". Awesome detailed tutorial series for Kubernetes. If your brain cells have been enjoying the quiet life, it's over, because boot camp is here. It tough going, but it's worth it.
