Hallo,
im new to docker. im a programmer and i've just i lil knowledge about servers and other dev-ops thinks. But our server administrator is now gone.

Im trying to outsource some services from our monolith app (to heavy for one droplet) to some microservices (each on his own droplet).

my target is:
123.123.123.123:80 => monolith app (droplet #1)
123.123.123.123:12345 => microservice 1 (droplet #2)
123.123.123.123:12346 => microservice 2 (droplet #3)
etc...

all with the same ssl certificate. the main app is written in php and runs on an apache server.
i will write the microservices in java, javascript and python.

did somebody has an tutorial, to do that?

greats, marco.
