2	magctl	Nitin Rajput, Shubham Tatvamasi, Vipin Rathi	CLI Tool	Proposal

Simple Summary

magctl is CLI Tool for magma, through which we will able to get results of list of tenants,feg,gateways on terminal itself. It will work similar to as kubectl in kubernetes. We are trying to use config in magctl similar to config used in kubernetes under .magmacli folder, so other can also easily access it.

Specification

This is the example of code that will give list of all Tenants created.

import (
	"crypto/tls"
	"encoding/json"
	"fmt"
	"io/ioutil"
	"log"
	"net/http"
	"os"

	"github.com/lensesio/tableprinter"
	"github.com/spf13/cobra"
)

// TenantsCmd represents the Tenants command
var TenantsCmd = &cobra.Command{
	Use:   "Tenants",
	Short: "List of all Tenants",
	Long: `A longer description that spans multiple lines and likely contains examples
and usage of using your command.`,
	Run: func(cmd *cobra.Command, args []string) {
		getTenants()
	},
}

func init() {
	getCmd.AddCommand(TenantsCmd)
}

type Tenants struct {
	ID       int      `header:"id"`
	Name     string   `header:"name"`
	Networks []string `header:"networks"`
}

func getTenants() {
	url := "https://api.galaxy.nitin.com/magma/v1/tenants"
	responseBytes := getTenantsData(url)
	// tenants := Tenants{}

	var tenants []Tenants

	if err := json.Unmarshal(responseBytes, &tenants); err != nil {
		log.Printf("Could not unmarshal reponseBytes. %v", err)
	}

	tableprinter.Print(os.Stdout, tenants)

}

func checkError(err error, hdr string) {
	if err != nil {
		fmt.Printf("[%s] Fatal error: %v\n", hdr, err.Error())
		os.Exit(1)
	}
}

func getTenantsData(baseAPI string) []byte {

	cert, err := tls.LoadX509KeyPair("/home/nitin/Project/magma/cmd/admin_operator.pem", "/home/nitin/Project/magma/cmd/admin_operator.key.pem")
	checkError(err, "loadcert")

	tr := &http.Transport{
		TLSClientConfig: &tls.Config{
			Certificates:       []tls.Certificate{cert},
			InsecureSkipVerify: true,
			ClientAuth:         tls.RequireAnyClientCert,
		},
	}
	client := &http.Client{Transport: tr}

	request, err := http.NewRequest(
		http.MethodGet, //method
		baseAPI,        //url
		nil,            //body
	)

	if err != nil {
		log.Printf("Could not request a magma api. %v", err)
	}

	request.Header.Add("Accept", "application/json")

	response, err := client.Do(request)
	if err != nil {
		log.Printf("Could not make a request. %v", err)
	}

	responseBytes, err := ioutil.ReadAll(response.Body)
	if err != nil {
		log.Printf("Could not read response body. %v", err)
	}

	return responseBytes
}

Result

The result which we get on our terminal.
