KrakenD Cobra

An adapter of the cobra lib for the KrakenD framework

Package cmd defines the cobra command structs and an execution method for adding an improved CLI to KrakenD based api gateways

Basic example

package main

import (
	"os"

	"github.com/krakendio/krakend-cobra/v2"
	"github.com/krakendio/krakend-viper/v2"
	"github.com/luraproject/lura/v2/config"
	"github.com/luraproject/lura/v2/logging"
	"github.com/luraproject/lura/v2/proxy"
	krakendgin "github.com/luraproject/lura/v2/router/gin"
)

func main() {

	cmd.Execute(viper.New(), func(serviceConfig config.ServiceConfig) {
		logger, _ := logging.NewLogger("DEBUG", os.Stdout, "")
		krakendgin.DefaultFactory(proxy.DefaultFactory(logger), logger).New().Run(serviceConfig)
	})

}

Available commands

The cmd package includes four commands: check, check-plugin, help and run.

1. check validates the received config file.
2. check-plugin validates the dependencies shared between the binary and a plugin.
3. help displays details about any command.
4. run executes the passed executor once the received flags overwrite the parsed config.
