Does anyone have a go-to guide for deploying {plumber} REST APIs on an on-premise server using Docker and Nginx? #rstats I used a tutorial earlier in the year, but I can't find it for some reason.

How does one deploy a {plumber} API using docker? I am looking to test an API preferably without having USD bill. #rstats I have seen a solution before however, I can't seem to find online.

Say hello to plumber2 🎉

plumber2 is a full rewrite of the plumber package for creating powerful webapis in #rstats. It takes everything we have learned from plumber and adds even more
