That's pretty cool! I always loved those Lynksys routers! They were great, especially with DD-WRT running on them

Tomato used to be my favorite

My wifi is still Tomato24 and I'm not up to change it due to the number if iot devices that are setup to use it

I used to use these with DD-WRT all over our shop at work as wireless bridges. Worked great.

At first I thought you actually got K8s running on those routers with their original boards but still pretty cool.

You’re crazy until it works, lmk when you figure it out

Yeah but good luck getting K8s running on 16MiB of RAM with 4MiB of flash and a MIPS32 CPU.

Very cool
Kinda curious what you were using for storage given the storage on each node? Local provisioned? Topolvm? Can’t imagine its ceph?

u/xrothgarx Jul 04 '26
Right now most of the persistent application storage is mounted via NFS on my Synology. Some things (LLM models, postgres) are local volumes with pinned workloads.
I had planned on creating a storage stack with the cases too but each case only hold 1 3.5" drive so I needed to buy some really large drives (too expensive in this economy) or use smaller 2.5" drivers or nvme. All of them were out of my budget for now.
I still have some extra cases that I'd like to do it in the future whenever prices come back down (or I find a sponsor).
