Hello everyone, as you may guess, I'm very new to Kotlin server side.
Do you know any article about best practices or helpful libraries for reading external configs (like the config.maps on kubernetes)?

[nfrankel]

are you using spring boot?
or just plain kotlin?

[Mehrdad Senobari]

It's just plain Kotlin

[nfrankel]

system properties would be the first step
https://docs.oracle.com/javase/tutorial/essential/environment/sysprop.html
pass -DXXX=YYY on the command line

[Mehrdad Senobari]

Great! I'll give it a try, thanks

[nfrankel]

then inside your app
System.getProperty("XXX") and it returns YYY

[nfrankel]

it starts getting bad when you need to pass a lot of parameters

[Mehrdad Senobari]

Luckily, I only need it for a very limited number of configs 🙂

[nfrankel]

in the case it grows too much
the next step is to use this system to point to a file
-Dconfig.file=/etc/myapp/my.properties

[nfrankel]

then you read the file

[nfrankel]

have fun!

better late than never : I like the lightbend config stuff much better than system properties. lightbend/config: configuration library for JVM languages using HOCON files (github.com)
