Not exactly the same configuration as the op, but if you are developing software using Go, the combination of Caddy, a single go binary, and systemd or some other supervisor is extremely flexible and i think is the way for running multiple services on a single VM. A shell script that deploys a couple config files and off you go. Use different accounts for each service for isolation and put all of your static files in your binary using embed.FS. No need for fancy configuration management or K8s.
