The one exception to this is if you’re using your homelab to learn kubernetes.
That was the only time I used K8s and k3s on my homelab.
And for anything that I do want to set up in a HA/cattle kind of way, I use Docker Swarm, as it feels like a more comfortable extension of docker compose.
I am using OpenBoard with bitwarden, and while it doesn’t offer the autofill in the autocomplete section it does work as a dropdown in the input field
