Audience question: on a VM that already runs a Rails app with Kamal, can you deploy another non-Rails service and have Kamal Proxy route to it on a different port? Strzibny: yes — Kamal isn't Rails-specific, same setup. If Kamal's CLI doesn't expose a capability you need, Kamal Proxy itself sometimes accepts lower-level commands you can invoke directly (analogous to how he lists managed projects via the proxy).
