flag

Documentation

Overview

Package flag implements shortcuts for parsing flags and creating kubernetes client from them.

Usage

Create ConfigFlag that by default looks for config in your home dir and use a shortcut to create kubernetes.Clientset

import kflag "github.com/bukowa/goutils/kubernetes/config/flag"
import "flag"

cf := kflag.NewConfigFlag()
// set flags
cf.Set()
// parse flags
flag.Parse()
// create kubernetes client
c, err := kubeConfigFlag.NewClient()

By default config file from home directory will be used `$HOME/.kube/config`. If you set --kubeconfig to empty value then client will use in-cluster config files.

cf := kflag.NewConfigFlag()
// change default to use in-cluster config
cf.Default = ""
// parse flags
flag.Parse()
// create kubernetes client
c, err := kubeConfigFlag.NewClient()
