Krakend-Generator

A tool for generating krakend configuration file with ease.

as we all know it is a good practice to generate the krakend configuration in a container and make it immune to further changes. so instead of writing the json file by hand (which easily you can get lost between definitions), or using krakend-designer (which shows a lot of useless settings) maybe the best choice is to write some codes which generate the config.json file for us. so you can simply generate the krakend.json file by using the defined structs.

Installation

we support go modules so for installing you can run:

go get -u github.com/p3ym4n/krakend-generator

Usage

a simple route definition using this tool is like below:

import kgen "github.com/p3ym4n/krakend-generator"

func main() {
    app := kgen.Default()
    
    app.AddEndpoints(
        kgen.NOOPEndpoint(kgen.GET, "/hello",
            kgen.NOOPBackend(kgen.GET, "github.com", "/hello"),
        ),
    )
    
    // config.json file is the path you want for the file
    if err := app.Generate("config.json"); err != nil {
        log.Fatalf("error occurred: %s",err)
    } else {
        log.Println("config.json generated.")
    }
}
