Hi,
I just started Golang (my first programming language).
Please I am trying to write a CLI app that will have the following command:
tk8 cluster aws
But I want the following flags to behave like this:
tk8 cluster aws --cloud (Initiate a cloud infrrastructure with necessary elements e.g EC2, VPC, etc)
tk8 cluster aws --install (start kubernetes installation on the AWS cloud)
Current code I have is this:

package cmd
import (
"bufio"
"fmt"
"log"
"os"
"os/exec"
"github.com/spf13/cobra"
)
var install,cloud string
// awsCmd represents the aws command
var awsCmd = &cobra.Command{
Use: "aws",
Short: "Manages the infrastructure on AWS",
Long: `Create, delete and show current status of the deployment that is running on AWS.
Kindly ensure that terraform is installed also.`,
Run: func(cmd *cobra.Command, args []string) {
fmt.Println("Testing")
},
}
func init() {
clusterCmd.AddCommand(awsCmd)
// Here you will define your flags and configuration settings.
// Cobra supports Persistent Flags which will work for this command
// and all subcommands, e.g.:
// awsCmd.PersistentFlags().String("foo", "", "A help for foo")
// Cobra supports local flags which will only run when this command
// is called directly, e.g.:
// awsCmd.Flags().BoolP("toggle", "t", false, "Help message for toggle")
awsCmd.Flags().BoolP(install, "i", true, "Start Kubernetes deployment on AWS")
awsCmd.Flags().BoolP(cloud, "c", true, "Deploy Cloud Infra on AWS")
}
I already have the codes snippets that will perform the installation but I don’t know where I should call the flags and then insert the code with respect to the command flags.
