I run a cluster of VMs that run kubernetes and manage those VMs with containers that run Terraform and ansible. Along with baremetal RISC-V workflows and ASICs.
A tool is a tool and one should pick what works for them.
Do you have experience with kubernetes or kubectl and DR or ASICs? Not everything should be a container or can do what an ASIC is built/designed for.
If I want a three node cluster for redundancy and speed I'll need three baremetal machines. Or one hypervisor hosting 3 VMs that run my cluster nodes. I think there is a knowlege gap. Check out these links if you have more questions.
Also some things cannot run as a container due to having architectural differences. These are specifically designed chips for prototyping and software development.
Lastly we all have different needs for our home labs. I have to research new tech and processes for my job. It's a lot of political overhead to get some stuff working on company hardware. I'm very lucky to have a good relationship with systems and storage so that I can buy older retired hardware to run at home. This is not everyone's usecase and that's fine.
