Considering I am the operations team, just goes to show how much I have left to learn. I didn't know about the external-dns operator.
Unfortunately, my company is a bit strange with certs and won't let me handle them myself. Something to check out at home I guess.
I agree with you about the LVM. I have been meaning to set up Rook forever but never got around to it. It might still take a while but thanks for the reminder.
Wow. That must have been some work. I don't have these certs myself but I'm looking at the CKA and CKS (or whatever that's called). For sure, I loved our discussion. Thanks for your help.
Yeah, I think you pick up things from all over the place as a consultant. I see lots of different environments and learn from them.
Ah yeah, external-dns operator is great! it's maybe a bit basic at times but its super convenient to just have A/AAAA records appear for all your loadbalancer svcs and HTTPRoutes. Saves a ton of time.
That's super unfortunate that the certs are siloed off. Maybe they can give you a NS record for a subdomain for you to use ACME on? I've seen that at some customers. Super important that all engineers have access to self-service certs, imo.
Rook is great! It definitely can be quite picky about hardware and balancing, as I've learned from trying to set it up with two nodes at home with spare hdds and ssds 😅 Very automated once it's all set up and you understand its needs, though. NFS provisioner is also a good option for a storageclass as a first step, that's what I used in my homelab from 2021 to 2023.
Heres my rook config:

Up to 3 nodes and 120TiB now and I'm about to add 4 more nodes. I probably would recommend just automatically adding disks instead of manually adding them, I'm just a bit more cautious and manual with my homelab "pets".
I'm not very far on my RHCE yet tbh 😅 Red hat courses are a bit hard to follow 😅 But hopefully will make some progress before the summer.
The CKA and CKS certs are great! Some really good courses for those on udemy and acloudguru, there's a good lab environment on killer.sh, and the practice exams are super useful. I definitely recommend those certs, you learn a lot and it's a good way to demonstrate your expertise.
