I've never seen komodo before, it seems like a cool project. If it supported moving workloads between servers, I'd probably consider switching away from k8s to it to have something simpler
I'd also recommend Authentik. It's simpler than something like keycloak imo and works pretty well. They also have guides for quite a few self hosted services.
I did have issues with it being slow at some point, but an update fixed it iirc.
I haven't used yacy in a whole, but i had configured it to auto import and index links from linkding. I also imported my browser history to get started.
Never tried the p2p option though so not sure how well that worked. I was worried about indexing private sites on accident .
I've been moving most of my homelab stuff to kubernetes. Right now it's a bunch of vms using talos and also a couple remote dedicated servers.
I was thinking of reinstalling my proxmox machines at home with talos, and using kubevirt for the things I still need VMs for.
Cozystack seems like it already manages most of the things I'd need?
It'd also be nice to be able to give access to a couple friends to their own virtual clusters on the remote servers.
