can this be used to proxy container traffic via caddy?

[halphalp]

i have caddy installed via opnsense on its own machine and would like to use it to proxy traffic for all of the servers in my network. on each server i have docker containers running, but i don't want to expose all of their ports in order for my opnsense caddy machine to be able to proxy to them.

if i set up docker-socket-proxy, can i limit the access to only my opnsense machine and then direct all of the caddy reverse proxy configurations to it?
