Install and Build

This project started using Go modules starting with version 2.1 and vendor directory is no longer bundled.

As per the modules documentation you no longer need to use GOPATH. You can clone the branch in any directory you like and go will fetch dependencies specified in the go.mod file:

cd ~/Documents/mycode
git clone https://github.com/vmware/go-vcloud-director.git
cd go-vcloud-director/govcd
go build

Note Do not forget to set GO111MODULE=on if you are in your GOPATH. Read more about this.

Example code

To show the SDK in action run the example:

mkdir ~/govcd_example
go mod init govcd_example
go get github.com/vmware/go-vcloud-director/v2@master
go build -o example
./example user_name "password" org_name vcd_IP vdc_name 

Here's the code:

package main

import (
	"fmt"
	"net/url"
	"os"

	"github.com/vmware/go-vcloud-director/v2/govcd"
)

type Config struct {
	User     string
	Password string
	Org      string
	Href     string
	VDC      string
	Insecure bool
}

func (c *Config) Client() (*govcd.VCDClient, error) {
	u, err := url.ParseRequestURI(c.Href)
	if err != nil {
		return nil, fmt.Errorf("unable to pass url: %s", err)
	}

	vcdclient := govcd.NewVCDClient(*u, c.Insecure)
	err = vcdclient.Authenticate(c.User, c.Password, c.Org)
	if err != nil {
		return nil, fmt.Errorf("unable to authenticate: %s", err)
	}
	return vcdclient, nil
}

func main() {
	if len(os.Args) < 6 {
		fmt.Println("Syntax: example user password org VCD_IP VDC ")
		os.Exit(1)
	}
	config := Config{
		User:     os.Args[1],
		Password: os.Args[2],
		Org:      os.Args[3],
		Href:     fmt.Sprintf("https://%s/api", os.Args[4]),
		VDC:      os.Args[5],
		Insecure: true,
	}

	client, err := config.Client() // We now have a client
	if err != nil {
		fmt.Println(err)
		os.Exit(1)
	}
	org, err := govcd.GetOrgByName(client, config.Org)
	if err != nil {
		fmt.Println(err)
		os.Exit(1)
	}
	vdc, err := org.GetVdcByName(config.VDC)
	if err != nil {
		fmt.Println(err)
		os.Exit(1)
	}
	fmt.Printf("Org URL: %s\n", org.Org.HREF)
	fmt.Printf("VDC URL: %s\n", vdc.Vdc.HREF)
