Hello, I recently graduate from docker-compose to k3s (homelab update). I followed a fairly good number of guide about how to set my stack back up, most of them endup using a combinason of kubectl apply -f <file> or equivalent with helm. Before I had docker-compose file that liked to sub docker compose file. Now I am not too sure about what would be the good practice. Especially considering the

/var/lib/rancher/k3s/server/manifests

folder. How do you recommand to handle all that?

I would look into something like Flux or ArgoCD. Basically you install those and point them to a git repo who will apply your manifests for you
