Godo

Godo is a Go client library for accessing the DigitalOcean V2 API.

You can view the client API docs here: http://godoc.org/github.com/digitalocean/godo

You can view DigitalOcean API docs here: https://developers.digitalocean.com/documentation/v2/

Usage

import "github.com/digitalocean/godo"

Create a new DigitalOcean client, then use the exposed services to access different parts of the DigitalOcean API.

Authentication

Currently, Personal Access Token (PAT) is the only method of authenticating with the API. You can manage your tokens at the DigitalOcean Control Panel Applications Page.

You can then use your token to create a new client:

package main

import (
	"context"
	"github.com/digitalocean/godo"
	"golang.org/x/oauth2"
)

const (
    pat = "mytoken"
)

type TokenSource struct {
	AccessToken string
}

func (t *TokenSource) Token() (*oauth2.Token, error) {
	token := &oauth2.Token{
		AccessToken: t.AccessToken,
	}
	return token, nil
}

func main() {
	tokenSource := &TokenSource{
		AccessToken: pat,
	}

	oauthClient := oauth2.NewClient(context.Background(), tokenSource)
	client := godo.NewClient(oauthClient)
}

Examples

To create a new Droplet:

dropletName := "super-cool-droplet"

createRequest := &godo.DropletCreateRequest{
    Name:   dropletName,
    Region: "nyc3",
    Size:   "s-1vcpu-1gb",
    Image: godo.DropletCreateImage{
        Slug: "ubuntu-14-04-x64",
    },
}

ctx := context.TODO()

newDroplet, _, err := client.Droplets.Create(ctx, createRequest)

if err != nil {
    fmt.Printf("Something bad happened: %s\n\n", err)
    return err
}

Pagination

If a list of items is paginated by the API, you must request pages individually. For example, to fetch all Droplets:

func DropletList(ctx context.Context, client *godo.Client) ([]godo.Droplet, error) {
    // create a list to hold our droplets
    list := []godo.Droplet{}

    // create options. initially, these will be blank
    opt := &godo.ListOptions{}
    for {
        droplets, resp, err := client.Droplets.List(ctx, opt)
        if err != nil {
            return nil, err
        }

        // append the current page's droplets to our list
        for _, d := range droplets {
            list = append(list, d)
        }

        // if we are at the last page, break out the for loop
        if resp.Links == nil || resp.Links.IsLastPage() {
            break
        }

        page, err := resp.Links.CurrentPage()
        if err != nil {
            return nil, err
        }

        // set the page we want for the next request
        opt.Page = page + 1
    }

    return list, nil
}

Versioning

Each version of the client is tagged and the version is updated accordingly.

Since Go does not have a built-in versioning, a package management tool is recommended - a good one that works with git tags is gopkg.in.

To see the list of past versions, run git tag.
