HDO: A HAskell Digital Ocean Client
Install the correct GHC version:
Build and install the package locally, possibly making executable
docean available from
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.
NOTE: Not all the available APIs from DO are implemented (yet).
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 '' 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 30876135 deploy-test [Active] ams2: Amsterdam 2 1024M/30G/1 cores IPv4 22.214.171.124/255.255.255.0 [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
-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 -
List all created droplets:
$ docean droplets list 21002433 droplet-01 [Active] sgp1: Singapore 1 1024M/30G/1 cores IPv4 126.96.36.199/255.255.240.0 [Public] IPv6 26082279 droplet-02 [Active] sgp1: Singapore 1 512M/20G/1 cores IPv4 188.8.131.52/255.255.240.0 [Public] IPv6 31114780 droplet-03 [Active] ams2: Amsterdam 2 2048M/40G/2 cores IPv4 184.108.40.206/255.255.240.0 [Public] IPv6
Shutdown/startup a droplet:
$ docean droplets power_off 31166171  2016-11-01 21:08:46 UTC -> - 31166171 PowerOff: InProgress
$ docean droplets power_on 31166171  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  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  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 The authenticity of host '220.127.116.11 (18.104.22.168)' can't be established. RSA key fingerprint is 3f:16:4f:f4:25:85:85:77:1e:90:bd:8c:6b:90:48:eb. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added '22.214.171.124' (RSA) to the list of known hosts.
