But I actually wish the interface were more like the apiserver.conf file--specifically, that you can define hard-coded credentials in this file in advance. Except, I wish that you could define API keys this way (or some other way)

auth {
    # Fixed users login credentials
    # No other user will be able to login
    fixed_users {
        enabled: true
        pass_hashed: false
        users: [
            {
                username: "test"
                password: "test"
                name: "Test User u:test p:test"
            }
        ]
    }
}
