Quarkus how to set environment variables in application.properties

recently I swapped from thorntail to quarkus and I'm facing some difficulties trying to find how to set environment variables in application.properties in thorntail I used something like this ${env.HOST: localhost} that basically means put environment variable, if you don't find anything put localhost as default is that possible to quarkus application.properties? I haven't found any issue on GitHub or someone that have an answered this problem?

In application.properties you can use:

somename=${HOST:localhost}

which will correctly expand the HOST environment variable and use localhost as the default value if HOST is not set.

See this for more information.

Alternatively, you do not need refere environment variable in application.properties, just refere variable in your code directly:

@ConfigProperty(name = "my.property", defaultValue = "default value")
String myProperty;

and specify it using env variable like this:

export MY_PROPERTY="env var" && java -jar myapp.jar

or using command line definition -D

java -Dmy.property="CL key" -jar myapp.jar

Please refere Quarkus configuration guide https://quarkus.io/guides/config
