Anyone know of an example/tutorial for a ktor rest server that uses productflavors so you can have different configuration variables for QA and production environments. Thanks

[Łukasz Bednarczyk]

Read about the HOCON file. You don’t need flavours 😉

You can use environment variables to configure each stage differently. Here you can find an information about taking values for parameters from environment variables in HOCON configuration.

Thanks guys. But I’m still not seeing how the Hocon file allows for diff configurations. I’m needs host =qa.example.com for one and host.example.com for another
Thanks

[Aleksei Tirman [JB]]

@Barry Fawthrop could you please describe how the host is used in your Ktor application?

[Barry Fawthrop]

Host is the database sever(clusters) one for dev, one for was and one for prod

[Łukasz Bednarczyk]

ok, so…where is the problem? You can define in HOCON file something like this:

ktor {
    environment = ${?KTOR_ENV}

    qa {
        host= xaxa
    }

    dev {
        host= dudu
    }
}

When you start your app, you have to define which config should start (qa or dev).

[Łukasz Bednarczyk]

@Barry Fawthrop You can also load different files with config depending on env

[Barry Fawthrop]

Thanks Lukasz, “when you start your app” you mean a command line parameter like —env = prod, right?

[Łukasz Bednarczyk]

yeah

[Barry Fawthrop]

Thank you
