DigitalOceanで使えるimageを一覧で取得する

tl;dr;

前置き

itamaeプラグインのCIを回してたら DigitalOceanで「centos-7-0-x64なんてイメージはないぞ！」ってエラーになりました

+ vagrant up centos70 --provider=digital_ocean
Bringing machine 'centos70' up with 'digital_ocean' provider...
==> centos70: Using existing SSH key: wercker-itamae-plugin-recipe-consul
There was an issue with the request made to the DigitalOcean
API at:

Path: /v2/droplets
URI Params: {:size=>"512MB", :region=>"nyc3", :image=>"centos-7-0-x64", :name=>"itamae-consul-centos70-59d3b5938e888f0001b27d75", :ssh_keys=>[1874082], :private_networking=>false, :ipv6=>false}

The response status from the API was:

Status: 422
Response: {"id"=>"unprocessable_entity", "message"=>"You specified an invalid image for Droplet creation."}

Vagrabtfileだと下記のように provider.image で設定してたのですが、どうも消えた模様。

  config.vm.define :centos70 do |c|
    c.vm.box = "centos/7"
    c.vm.provider :digital_ocean do |provider, override|
      provider.image = "centos-7-0-x64"
    end
    c.vm.hostname  = 'itamae-consul-centos70'
    c.vm.hostname  += "-#{ENV['WERCKER_RUN_ID']}" if ENV['WERCKER_RUN_ID']
  end

実際に使えるイメージ一覧を自分のgistには乗っけてはいたんですが、ググれる場所にあった方が便利なのでブログに記載

使い方

はじめに https://cloud.digitalocean.com/settings/api/tokens でAPIトークンを取得

あとはこんな感じに実行したらjsonがとれます。下記のslugをVagrantfileに渡してやればよさそう

$ export DIGITALOCEAN_ACCESS_TOKEN="xxxxxxxxxxxxxxx"
$ curl -s "https://api.digitalocean.com/v2/images?filter=global&per_page=100" -H "Authorization: Bearer $DIGITALOCEAN_ACCESS_TOKEN" | jq .

{
  "images": [
    {
      "id": 27983450,
      "name": "1520.4.0 (beta)",
      "distribution": "CoreOS",
      "slug": "coreos-beta",
      "public": true,
      "regions": [
        "nyc1",
        "sfo1",
        "nyc2",
        "ams2",
        "sgp1",
        "lon1",
        "nyc3",
        "ams3",
        "fra1",
        "tor1",
        "sfo2",
        "blr1"
      ],

slugで検索したい場合はこんな感じ

$ curl -s "https://api.digitalocean.com/v2/images?filter=global&per_page=100" -H "Authorization: Bearer $DIGITALOCEAN_ACCESS_TOKEN" | jq -r ".images[].slug" | grep centos
centos-6-5-x32
centos-6-5-x64
centos-6-x32
centos-6-x64
centos-7-x64

jsonはここに置いてるのでページ内検索でも探せます
