So, my Clojure app is running in a container on top of the drone executor container. I can expose the app container nrepl port and I can see the port in the drone executor container. But I need to expose this port further from the drone executor container to my developer machine host in order to be able to connect to the nrepl server.
drone has a new feature that allows you to execute a pipeline in debug mode and remotely connect to a pipeline container of a failed build step using a remote terminal. Check out Piping conversion extensions
