Supporting Rest API SDK V2.0
This is a fully featured REST API client for DnsMadeEasy provider. DME is an excellent provider, and is highly recommended for their ease of use, very solid API, and great customer support. They also offer free DNS failover with business accounts, which is highly recommended for the arrays of load balancers in front of your app.
Usage
DnsMadeEasy allows you to fetch, create, update DNS records, as long as you know your API key and the secret.
Setting up Credentials
You can find your API Key and Secret on the Account Settings Page of their UI.
Once you have the key and the secret, you have several choices:
-
You can directly instantiate a new instance of the
Client
class, by passing your API key and API secrets as arguments:require 'dnsmadeeasy' @client = DnsMadeEasy::Api::Client.new(api_key, api_secret)
-
Or, you can use the
DnsMadeEasy.configure
method to configure the key/secret pair, and then useDnsMadeEasy
namespace to call the methods:require 'dnsmadeeasy' DnsMadeEasy.configure do |config| config.api_key = 'XXXX' config.api_secret = 'YYYY' end DnsMadeEasy.domains.data.first.name #=> 'moo.gamespot.com'
-
Configuring API keys as above is easy, and can be done using environment variables. Alternatively, it may be convenient to store credentials in a YAML file.
-
* If filename is not specified, there is default location where this file is searched, which is `~/.dnsmadeeasy/credentials.yml`. * If filename is provided, it will be read, and must conform to the following format:
Simple Credentials Format
# file: ~/.dnsmadeeasy/credentials.yml
credentials:
api_key: 2062259f-f666b17-b1fa3b48-042ad4030
api_secret: 2265bc3-e31ead-95b286312e-c215b6a0
Multi-Account Credentials Format
Below you see two accounts, with production key and secret being encrypted. See further below about encrypting your key and secrets.
accounts:
- name: development
default_account: true
credentials:
api_key: 12345678-a8f8-4466-ffff-2324aaaa9098
api_secret: 43009899-abcc-ffcc-eeee-09f809808098
- name: production
credentials:
api_key: "BAhTOh1TeW06OkRhdGE6OldyYXBwZXJT............"
api_secret: "BAhTOh1TeW06OkRhdGE6OldyYXBwZ............"
encryption_key: spec/fixtures/sym.key
You can use the following method to access both simple and multi-account YAML configurations:
require 'dnsmadeeasy'
DnsMadeEasy.configure_from_file(file, account = nil, encryption_key = nil)
# for example:
DnsMadeEasy.configure_from_file('config/dme.yaml', 'production')
DnsMadeEasy.domains #=> [ ... ]
# or with encrypted key passed as an argument to decrypt YAML values:
DnsMadeEasy.configure_from_file(
'config/dme.yaml',
'production',
ENV['PRODUCTION_KEY'])
-
Finally, you can use
DME.credentials_from_file
method that, unlike the method above, uses hash arguments:
@creds = DnsMadeEasy.credentials_from_file(file: 'my-creds.yml',
account: 'production',
encryption_key: 'MY_KEY')
@creds.api_key # => ...
@creds.api_secret # => ...
Method above simply returns the credentials instance, but does not "save" it as the default credentials like configure_from_file
. Therefore, if you need to access multiple accounts at the same time, this method will help you maintain multiple credentials at the same time.
Once you configure the keys, you can also use the shortcut module to save you some typing:
require 'dnsmadeeasy/dme'
DME.domains.data.first.name #=> 'moo.gamespot.com'
This has the advantage of being much shorter, but might conflict with existing modules in your Ruby VM.
In this case, just do not require dnsmadeeasy/dme
and only require dnsmadeeasy
, and you’ll be fine.
Otherwise, using DME
is identical to using DnsMadeEasy
, assuming you required dnsmadeeasy/dme
file.
Which Namespace to Use? What is DME
versus DnsMadeEasy
?
Since DnsMadeEasy
is a bit of a mouthful, we decided to offer (in addition to the standard DnsMadeEasy
namespace) the abbreviated module DME
that simply forwards all messages to the module DnsMadeEasy
. If in your Ruby VM there is no conflicting top-level class DME
, then you can require 'dnsmadeeasy/dme'
to get all of the DnsMadeEasy client library functionality without having to type the full name once. You can even do require 'dme'
.
Whenever you require dme
you also import the DnsMadeEasy
namespace. The opposite is not true.
So if you DO have a name clash with another top-level module DME
, simply do require 'dnsmadeeasy'
and none of the DME
module namespace will be loaded.
In a nutshell you have three ways to access all methods provided by the DnsMadeEasy::Api::Client
class:
-
Instantiate and use the client class directly,
-
Use the top-level module
DnsMadeEasy
withrequire 'dnsmadeeasy'
-
Use the shortened top-level module
DME
withrequire 'dnsmadeeasy/dme'
Examples
Whether or not you are accessing a single account or multiple, it is recommended that you save your credentials (the API key and the secret) encrypted in the above mentioned file ~/.dnsmadeeasy/credentials.yml
(or any file of you preference).
Warning
|
DO NOT check that file into your repo! If you use encryption, do not check in your key! |
The examples that follow assume credentials have already been configured, and so we explore the API.
Using the DME
module (or DnsMadeEasy
if you prefer) you can access all of your records through the available API method calls, for example:
IRB > require 'dme' #=> true
# Or you can also do
IRB > require 'dnsmadeeasy/dme' #=> true
IRB > DME.domains.data.map(&:name)
⤷ ["demo.gamespot.systems",
"dev.gamespot.systems",
"gamespot.live",
"gamespot.systems",
"prod.gamespot.systems"
]
# These have been read from the file ~/.dnsmadeeasy/credentials.yml
IRB > DME.api_key
⤷ "2062259f-f666b17-b1fa3b48-042ad4030"
IRB > DME.api_secret
⤷ "2265bc3-e31ead-95b286312e-c215b6a0"
IRB > DME.domain('gamespot.live').delegateNameServers
⤷ #<Hashie::Array ["ns-125-c.gandi.net.", "ns-129-a.gandi.net.", "ns-94-b.gandi.net."]>
# Let's inspect the Client — after all, all methods are simply delegated to it:
IRB > @client = DME.client
⤷ #<DnsMadeEasy::Api::Client:0x00007fb6b416a4c8
@api_key="2062259f-f666b17-b1fa3b48-042ad4030",
@api_secret="2265bc3-e31ead-95b286312e-c215b6a0",
@options={},
@requests_remaining=149,
@request_limit=150,
@base_uri="https://api.dnsmadeeasy.com/V2.0">
Next, let’s fetch a particular domain, get it’s records and compute the counts for each record type, such as 'A', 'NS', etc.
IRB > records = DME.records_for('gamespot.com')
IRB > [ records.totalPages, records.totalRecords ]
⤷ [1, 33]
IRB > records.data.select{|f| f.type == 'A' }.map(&:name)
⤷ ["www", "vpn-us-east1", "vpn-us-east2", "staging", "yourmom"]
IRB > types = records.data.map(&:type)
⤷ [....]
IRB > require 'awesome_print'
IRB > ap Hash[types.group_by {|x| x}.map {|k,v| [k,v.count]}]
{
"MX" => 2,
"TXT" => 1,
"CNAME" => 3,
"NS" => 22,
"A" => 5
}
Return Value Types
All public methods of this library return a Hash-like object, that is actually an instance of the class Hashie::Mash
. Hashie::Mash
supports the very useful ability to reach deeply nested hash values via a chain of method calls instead of using a train of square brackets. You can always convert it to a regular hash either to_hash
or to_h
on an instance of a Hashie::Mash
to get a pure hash representation.
Noteto_hash
converts the entire object to a regular hash, including the deeply nested hashes, whileto_h
only converts the primary object, but not the nested hashes. Here is an example below — in the first instance where we callto_h
we are still able to call.value
on the nested object, because only the top-levelMash
has been converted into aHash
. In the second example, this call fails, because this method does not exist, and the value must be accessed via the square brackets:
IRB > recs.to_h['data'].last.value
⤷ "54.200.26.233"
IRB > recs.to_hash['data'].last.value
"NoMethodError: undefined method `value` for #<Hash:0x00007fe36fab0f68>"
IRB > recs.to_hash['data'].last['value']
⤷ "54.200.26.233"

Encryption
It was mentioned above that the credentials YAML file may contain encrypted values. This facility is provided by the encryption gem Sym.
In order to encrypt your values, you need to perform the following steps:
gem install sym
# let's generate a new key and save it to a file:
sym -g -o my.key
# if you are on Mac OS-X, you can import the key into the KeyChain.
# this creates an entry in the keychain named 'my.key' that can be used later.
sym -g -x my.key
Once you have the key generated, first, make sure to never commit this to any repo!. You can use 1Password for it, or something like that.
Let’s encrypt our actual API key:
api_key="12345678-a8f8-4466-ffff-2324aaaa9098"
api_secret="43009899-abcc-ffcc-eeee-09f809808098"
sym -ck my.key -e -s "${api_key}"
# => prints the encrypted value
# On a mac, you can copy it to clipboard:
sym -ck my.key -e -s "${api_secret}" | pbcopy
Now, you place the encrypted values in the YAML file, and you can save "my.key" as the value against encryption_key:
at the same level as the api_key
and api_secret
in the YAML file. This value can either point to a file path, or be a keychain name, or even a name of an environment variable. For full details, please see sym documentation.
CLI Client
This library offers a simple CLI client dme
that maps the command line arguments to method arguments for corresponding actions:
You can run dme operations
to see the supported list of operations:
❯ dme op
Actions:
Checkout the README and RubyDoc for the arguments to each operation,
which is basically a method on a DnsMadeEasy::Api::Client instance.

Managing Domains
Note
|
below we can be using @client instantiated with given key and secret, or
DME or DnsMadeEasy module.
|
To retrieve all domains:
require 'dnsmadeeasy/dme'
DME.domains
To retreive the id of a domain by the domain name:
DME.get_id_by_domain('test.io')
To retrieve the full domain record by domain name:
DME.domain('test.io')
To create a domain:
DME.create_domain('test.io')
# Multiple domains can be created by:
DME.create_domains(%w[test.io moo.re])
To delete a domain:
DME.delete_domain ('test.io')
Managing Secondary Domains
To retrieve all secondary domains:
DME.secondary_domains
To retrieve secondary domain by id:
DME.secondary_domain(domain_id)
To retrieve the id of a domain by the secondary domain name:
DME.get_id_by_secondary_domain('test.io')
To create a secondary domain:
# IP_SET_ID is id of ip_set you want to associate domain with
DME.create_secondary_domain('test.io', IP_SET_ID)
# Multiple domains can be created by:
DME.create_secondary_domains(%w[test.io moo.re], IP_SET_ID)
To update a secondary domain:
# IP_SET_ID is id of ip_set you want to associate
# DOMAIN_ID is id of domain
DME.update_secondary_domains([DOMAIN_ID], IP_SET_ID)
To delete a secondary domain:
DME.delete_secondary_domain('test.io')
Managing Secondary IpSets
To retrieve all secondary IpSets:
DME.secondary_ip_sets
To retrieve single ipSet:
DME.secondary_ip_set(IP_SET_ID)
To create an ipSet:
# IP_LIST is list of ips to be associated with this ip_set, like %w[8.8.8.8, 1.1.1.1]
DME.create_secondary_ip_set('ip-set-name', IP_LIST)
To update an ipSet:
DME.update_secondary_ip_set(IP_SET_ID, 'ip-list-name', IP_LIST)
To delete an ipSet:
DME.delete_secondary_ip_set(IP_SET_ID)
Managing Records
To retrieve all records for a given domain name:
DME.all('test.io')
To find the record id for a given domain, name, and type:
This finds all of the IDs matching 'woah.test.io' type 'A':
DME.find_record_ids ('test.io', 'woah', 'A')
# => [ 234234, 2342345 ]
# To delete a record by domain name and record id (the record id can be retrieved from `find_record_id`:
DME.delete_record ('test.io', 123)
# To delete multiple records:
DME.delete_records ('test.io', [123, 143])
# To delete all records in the domain:
DME.delete_all_records ('test.io')
To create records of various types:
# The generic method:
DME.create_record ('test.io', 'woah', 'A', '127.0.0.1', { 'ttl' => '60' })
# Specialized methods:
DME.create_a_record ('test.io', 'woah', '127.0.0.1', {})
