I was thinking about migrating my services to self management k8s cluster, mostly for education purposes. I have some low traffic services running on one dedicated server on Scaleway now - there's some nextcloud, portainer, hastebin (sort of pastebin) mysql database, personal wiki, couple of half-dead blogs, stuff like that. Nothing resources heavy, nothing that needs tight SLA. I plan to add a little of my own software anytime soon, but I don't expect it to be very needy as well.

I'm planning on going with 3 nodes with min. 2 cores and 4 GB of RAM, and an additional service for storage. Does anyone here had experience with self hostes kubernetes? Do you have any advices? Do you think nodes like these are enough or I should upgrade (or downgrade)? Can you reccomend some providers that could offer this setup at low cost?
