A DSL for managing your DNS on cloud services through fog.
Clouddns allows a convenient way to manage DNS on Amazon Route 53, bluebox, DNSimple, DNS Made Easy, Linode DNS, Slicehost DNS or Zerigo DNS. DNS records are described by configuration files in ruby, which are in a readable commentable format. This also allows keeping your DNS configuration in version control. Since DNS records are described in ruby, they can be defined programmatically, allowing DNS records to be made from database entries or other sources like a chef server.
gem install clouddns
To change your DNS to that in the config file run
clouddns migrate dns.rb
Where dns.rb is a file in the following format
The configuration files used by clouddns are written in ruby and specify zones at the top level, and records within.
Zones group all records within a domain (usually, second-level or third-level).
Within these zones, records are declared in the format TYPE 'FULL.DOMAIN.NAME' 'VALUE'
provider 'AWS'
defaults :ttl => 600
zone 'example.com' do
A 'example.com', '1.2.3.4'
CNAME 'www.example.com', 'example.com.'
A 'mail.example.com', '4.3.2.1'
MX 'www.example.com', '10 mail.example.com.', :ttl => 300
end
zone 'example.net' do
A 'www.example.net', '1.2.3.4'
end
Defines a zone. Takes one argument, the fully qualified domain name, and a block, which declares the records associated with the zone. Domain names can end with a dot, if missing, is is implied.
Records must be defined within a zone. They are defined by calling the helper method for their type (A, CNAME, etc) with their FQDN, value, and any options. If the domain name is missing the trailing dot, it is implied.
Value can be an array to specify multiple entries for that record (like in the case of Round-robin DNS, or multiple MX records).
Options is currently only :ttl, which is specified in seconds. :ttl defaults to 3600, which can be changed using the defaults directive.
Credentials are required to access whichever service is desired through dns. This can be specified in full in the config file
provider 'AWS',
:aws_secret_access_key => YOUR_SECRET_ACCESS_KEY,
:aws_access_key_id => YOUR_SECRET_ACCESS_KEY_ID
Alternatively, to avoid specifying access keys or access key in the file (A good idea if it's to enter version control),
fog will read credentials from ~/.fog or the file specified in ENV["FOG_RC"].
One can then specify the provider by itself in the config file (like provider 'AWS') or using the -p PROVIDER option of the clouddns executable.
Defaults specified options which will be used by any zones or records defined in the file. Currently, this can only be used to specify :ttl.
