You can do no-downtime deploy of a web service with:

- Kamal

- Docker compose with Caddy (lb_try_duration to hold requests while the HTTP container restarts)

- Systemd using socket activation (same as Docker compose, it holds HTTP connections while the HTTP service restarts)

So you don't have to buy the whole pig and butcher it to eat bacon.

Nit: it holds the TCP connections while the HTTP service restarts. Any HTTP-level stuff would need to be restarted by the client. But that’s true of every “zero downtime” system I’m aware of.
