So my boss wants me spun up on OpenShift asap and wants me to have a functioning bare metal install on my laptop by the end of the week. Essentially I just need a working master and compute node. I've already installed OKD before but that's a cakewalk compared to creating the UPI which I really have no experience with. I've read through the red hat 4.3 bare metal installation docs but I'm still a bit lost on the way I should create my UPI. I'm not going to lie, I'm extremely anxious about this right now and I feel like I'm in far too deep over my head.
Would it make sense to put DNS/HAProxy/DHCP/PXE all on the same VM? I plan on using rhel8 on Virtualbox. Past this point I'm not sure what the next step would be. I know it'll definitely be a ghetto setup but my boss is the kinda guy that likes that learning process.
Have you looked at CodeReady Containers?
It is not bare metal and it is not identical to what a bare metal installation provides, but it's considerably simpler to get running and for some purposes, it will be more useful.
Consider also that the bare metal installation documented requirements:
, include a temporary bootstrap machine (16 GB RAM), three masters (3x16 = 48 GB RAM) and two workers (2x8 = 16 GB RAM), so 80 GB of RAM. You might be able to squeeze that reasonably into a single laptop, or deviate from the supported requirements to make that fit in your hardware, but that's something that CodeReady Containers already has solved and supports (it is a reduced installation which only requires 8 GB).
Since of CodeReady Containers version 1.10 : the minimum requirement is 9 GB RAM, although for proper performance a minimum of 12 GB is recommended. Just for your information. :)
