Hi, I have a question regarding the application.conf file when using ktor. I’m trying this for the first time so pardon me. I’ve created a conf file as follows:

ktor {
  deployment {
      port = 8080
  }

  application {
      modules = [ com.example.ApplicationKt.module ]
  }
}

jwt {
 "secret" = ${m_secret}
 "issuer" = "my_issuer"
 ….
}

I would like to extract the values for the jwt properties into an environment file so that i don’t publish my secrets into version control. What’s the best way to do this? I tried accessing the value of ${m_secret} from a dev.env file which I set as m_secret="secret" but that didn’t work as I run into the following error: Could not resolve substitution to a value: ${m_secret} . Thanks in advance.

The syntax looks correct, are you sure that the dev.env file is correctly used for variable substitution? Have you tried running with a direct environment variable?

m_secret is the value. I guess, you should use the key: secret, probably with its path: jwt.secret.

I think the .conf file is just a text file, so I don’t think it’ll grab the actual environment variable. Those variables are used in Security.kt in the default project setup, so you could access the environment variables there instead.

Thanks for all the help. So I finally figured it out. I’m using IntelliJ and in the Run/Debug Configurations I had to enable the use of the EnvFile and attach my dev.env file as shown in the attached image. After that, I could pass the environment variables from my dev.env file.
