09/27/2018, 9:23 PMHiya, 2 beginner questions:
1. What’s the best way to run ktor server in production? I just need simple microservice running in docker in kubernetes. Do I just use embeddedServer() ? I don’t really know the difference between embedded vs non-embedded server, I missed whole “java ee embedded tomcat” thing and don’t know what “embedded” is supposed to mean. I am asking this question mainly because almost all ktor samples are starting engines directly without calling embeddedServer().
2. I expected easy way of reading .conf files, I thought that they automagically would load up to some global config file, but it doesn’t seem to be the case. How was it intended to use and load .conf files?

2. The idea is to have a single application.conf, that does the startup magic (loading the file, setting up the server with the right engine and the configured port, etc.). The rest of the things are magic-less.

09/27/2018, 10:34 PMthank you, follow up question: when I use embedded server and don’t set port, it defaults to 80 and doesn’t pick up the value from the config. Should I use commandLineEnvironment(args) for auto-magical set up?

09/27/2018, 10:36 PMit’s just feels weird to call something called “commandLine” to actually read from the file

09/27/2018, 10:45 PMYeah, I mean i know it does it additionally, but the name is deceiving, it does a lot more than the name states

10/01/2018, 12:08 PMFWIW, because I prefer to manage my own config, I have just a plain main method like any other Java program that does what I want to do with config and feeds the relevant bits of that to
embeddedServer()mp
10/01/2018, 12:09 PMThis works fine in production (and allows me the flexibility to have config provided in different ways for local dev and prod, which is useful in my situation).
