HDO: A HAskell Digital Ocean Client

This is a Digital Ocean client written in Haskell. It can be used either as a library or as command-line utility.

Build

hdo is built with stack, using Stackage LTS-7.7 dependencies. To build, follow the standard instructions:

Install the correct GHC version:

stack setup

Build and install the package locally, possibly making executable docean available from PATH:

stack install

Usage

Command-line Tool

Command-line tool is named docean. If it's been installed, it should be available in your PATH. Otherwise, you can run it from the source directory using stack exec docean -- <args>. docean expects authentication token to be available from environment variable AUTH_TOKEN, see Digital Ocean API for details on how to get that authentication token.

export AUTH_TOKEN=2342342341234eaf

Available Commands

NOTE: Not all the available APIs from DO are implemented (yet).

Droplets

Creating a Droplet

This is the most complex command, as creating a droplet can use a lot of different options.

$ docean droplets create -r ams2 -s 1gb -i ubuntu-16-04-x64 -n deploy-test -k '[2436510]'
waiting for droplet deploy-test to become Active: 60s
waiting for droplet deploy-test to become Active: 59s
waiting for droplet deploy-test to become Active: 58s
waiting for droplet deploy-test to become Active: 57s
waiting for droplet deploy-test to become Active: 56s
waiting for droplet deploy-test to become Active: 55s
waiting for droplet deploy-test to become Active: 54s
waiting for droplet deploy-test to become Active: 53s
waiting for droplet deploy-test to become Active: 52s

       95.85.44.239/255.255.255.0 [Public]
     IPv6

The available parameters are:

• -r|--region: Sets the region where droplet is created, using the region slug
• -s|--size: Sets the size of the droplet, from 512mb to 96gb
• -n|--name: Name of the newly created droplet
• -i|--image: Slug of the image to use as base image for droplet
• -k|--keys: List (in the form readable by Haskell to convert to type [Int]) of keys to add for accessing the droplet
• -b|--background: Create droplet in the background, returning only the identifier of action to be checked later. If not set, creation is synchronous: The client will check wait for droplet to be up for 60s.

When successfully created, the main characteristics of the droplet are printed to the console.

Other Droplet Operations

Destroy an existing droplet:

$ droplets destroy 30876135

Shutdown/startup a droplet:

$ docean droplets power_off 31166171
[163908062] 2016-11-01 21:08:46 UTC -> -
     31166171 PowerOff: InProgress

$ docean droplets power_on 31166171
[163908350] 2016-11-01 21:10:16 UTC -> -
     31166171 PowerOn: InProgress

Retrieve status of an action initiated on the droplet (usually related to power on/off or snapshots):

$ docean droplets action 31166171 163908062
[163908062] 2016-11-01 21:08:46 UTC -> 2016-11-01 21:08:58 UTC
     31166171 PowerOff: Completed

Take a snapshot of an existing droplet (must be powered off):

$ docean droplets snapshot 31166171 mysnapshot
[163908530] 2016-11-01 21:11:19 UTC -> -
     31166171 MakeSnapshot: InProgress

List existing snapshots for droplet:

$ docean droplets 31166171 snapshots
20648640 mysnapshot Ubuntu

Connect to the droplet through SSH (can be given a name or a droplet ID):

$ docean droplets ssh 31166171
