This category will be all about using DigitalOcean's various Cloud products and services.

DigitalOcean API

Note: This category and associated articles will only cover version 2 (v2) of the DigitalOcean API.

Environment variables

$ API_URL="https://api.digitalocean.com/v2"
$ TOKEN=<YOUR_API_TOKEN>

I will be using the above environment variables for the remainder of this article.

Account

• Get your DigitalOcean (basic) account information:

$ curl -sXGET "${API_URL}/account" \
       -H "Authorization: Bearer ${TOKEN}" \
       -H "Content-Type: application/json" | python -mjson.tool
{
    "account": {
        "droplet_limit": 25,
        "email": "bob@example.com",
        "email_verified": true,
        "uuid": "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"
    }
}

Regions

$ curl "${API_URL}/regions" \
       -H "Authorization: Bearer ${TOKEN}" \
       -H "Content-Type: application/json" | python -mjson.tool

• ams1 ("Amsterdam 1")
• ams2 ("Amsterdam 2")
• ams3 ("Amsterdam 3")
• fra1 ("Frankfurt 1")
• lon1 ("London 1")
• nyc1 ("New York 1")
• nyc2 ("New York 2")
• nyc3 ("New York 3")
• sfo1 ("San Francisco 1")
• sgp1 ("Singapore 1")

A quick-and-dirty way to get a pretty table output of the DigitalOcean regions available for Droplets (and the associated sizes and features) is with a Python script something like the following:

#!/usr/bin/env python
import re, sys, json, requests
from prettytable import PrettyTable
TOKEN = "<REDACTED>"
ENDPOINT = "https://api.digitalocean.com/v2"
headers = {'Content-Type': 'application/json',
           "Authorization": "Bearer %s" % TOKEN}
r = requests.get(ENDPOINT + "/regions", headers=headers)
if r.status_code == 200:
    regions = r.json()['regions']
else:
    print "Could not connect to DigitalOcean\n"
    sys.exit(0)

table = PrettyTable(["Slug", "Name", "Sizes", "Features"])
table.align = "l"

size_re = re.compile(r"^(\d+)(.*)$")
mult = dict(KB=2**10, MB=2**20, GB=2**30)

def getsize(size):
    value = size_re.match(size).group(1)
    unit = size_re.match(size).group(2)
    multiplier = mult[unit.upper()]
    return float(value) * multiplier

for region in regions:
    slug = region["slug"]
    name = region["name"]
    region["sizes"].sort(key=getsize)
    sizes = ', '.join(region["sizes"]) \
            if region["available"] else "<unavailable>"
    features = ', '.join(region["features"])
    table.add_row([slug, name, sizes, features])

print table.get_string(sortby="Slug")

Running the above script produces:

+------+-----------------+---------------------------------------------------+---------------------------------------------+
| Slug | Name            | Sizes                                             | Features                                    |

| nyc3 | New York 3      | 512mb, 1gb, 2gb, 4gb, 8gb, 16gb, 32gb, 48gb, 64gb | private_networking, backups, ipv6, metadata |

Droplets

• Create a Droplet:

$ curl -vXPOST "${API_URL}/droplets" \
   -d'{"name":"my-test-droplet","region":"nyc3","size":"512mb","image":"ubuntu-14-04-x64"}' \
   -H "Authorization: Bearer ${TOKEN}" \
   -H "Content-Type: application/json"

# RESPONSE BODY:
{
    "droplet": {
        "backup_ids": [],
        "created_at": "2015-05-05T20:26:24Z",
        "disk": 20,
        "features": [
            "virtio"
        ],
        "id": 1234567,
        "image": {},
        "kernel": {
            "id": 2924,
            "name": "Ubuntu 14.04 x64 vmlinuz-3.13.0-43-generic",
            "version": "3.13.0-43-generic"
        },
        "locked": true,
        "memory": 512,
        "name": "my-test-droplet",
        "networks": {},
        "next_backup_window": null,
        "region": {},
        "size": {},
        "size_slug": "512mb",
        "snapshot_ids": [],
        "status": "new",
        "vcpus": 1
    },
    "links": {
        "actions": [
            {
                "href": "https://api.digitalocean.com/v2/actions/87654321",
                "id": 87654321,
                "rel": "create"
            }
        ]
    }
}

• List Droplets on your account:

$ curl -XGET "${API_URL}/droplets" \
       -H "Authorization: Bearer ${TOKEN}" \
       -H "Content-Type: application/json" | python -mjson.tool

Or, pretty print the output:

$ curl -sXGET "${API_URL}/droplets" \
       -H "Authorization: Bearer ${TOKEN}" \
       -H "Content-Type: application/json" |\
       python -c 'import sys,json;data=json.loads(sys.stdin.read());\
                  print "ID\tName\tRegion\n";\
                  print "\n".join(["%s\t%s\t%s"%(d["id"],d["name"],d["region"]["slug"])\
                  for d in data["droplets"]])'|column -t

ID       Name               Region
1234567  my-test-droplet-1  nyc3
2345678  my-test-droplet-2  ams1

• List the details of a given Droplet:

$ DROPLET_ID=1234567
$ curl -sXGET "${API_URL}/droplets/${DROPLET_ID}" \
       -H "Authorization: Bearer ${TOKEN}" \
       -H "Content-Type: application/json" | python -mjson.tool

• Delete a given droplet:

$ DROPLET_ID=1234567
$ curl -X DELETE "${API_URL}/droplets/${DROPLET_ID}" \
       -H "Authorization: Bearer ${TOKEN}" \
       -H 'Content-Type: application/json'

Images

A quick-and-dirty way to get a pretty table output of the DigitalOcean images available for Droplets is with a Python script something like the following:

#!/usr/bin/env python
import sys, requests
from prettytable import PrettyTable
TOKEN = "<REDACTED>"
ENDPOINT = "https://api.digitalocean.com/v2"
headers = {'Content-Type': 'application/json',
           "Authorization": "Bearer %s" % TOKEN}
r = requests.get(ENDPOINT + "/images", headers=headers)
errmsg = "Could not connect to DigitalOcean. Exiting..."
images = r.json()['images'] if r.status_code == 200 else sys.exit(errmsg)

table = PrettyTable(["ID", "Slug", "Distribution", "Name", "Type"])
table.align = "l"
[table.add_row([image["id"], image["slug"], image["distribution"],
                image["name"], image["type"]]) for image in images]

print table.get_string(sortby="Slug")

Running the above script produces:

+----------+------------------+--------------+------------------+----------+
| ID       | Slug             | Distribution | Name             | Type     |
