pdns.cr

pdns.cr provides a crystal api to interact with the JSON API of PowerDNS

Installation

1. Add the dependency to your shard.yml:

dependencies:
 pdns:
   github: repomaa/pdns

1. Run shards install

Usage

Creating an API Instance

require "pdns"

api = Pdns::API.new("https://your-pdns.tld", "your-api-key")

Listing servers

pp api.servers.list

Listing zones on a server

api.servers.with("localhost") do |server|
  pp server.zones.list
end

Editing a zone

api.servers.with("localhost") do |server|
  server.zones.edit_rrsets("my-domain.tld.") do |rrsets|
    # delete all CNAMEs
    rrsets.select(&.type.cname?).each(&.delete!)

    # modify a resource record set
    rrset = rrsets.find do |rrset|
      rrset.type.a? && rrset.name == "www.my-domain.tld."
    end

    raise "No such A record" if rrset.nil?

    rrset.records = [Pdns::Record.new("127.0.0.1")]
    rrset.replace!

    # add a record
    rrsets << Pdns::RRSet.new(
      name: "www.my-domain.tld.",
      type: Pdns::DNSRecordType::AAAA,
      ttl: 3600_u32,
      records: [Pdns::Record.new("::1")],
    )
  end
end

Listing cryptokeys in a zone on a server

api.servers.with("localhost") do |server|
  server.zones.with("my-domain.tld.") do |zone|
    zone.cryptokeys.list
  end
end

Adding a cryptokey to a zone on a server

api.servers.with("localhost") do |server|
  server.zones.with("my-domain.tld.") do |zone|
    key = Pdns::Cryptokey.new(
      key_type: "csk",
      bits: 256_u16
    )
    zone.cryptokeys.create(key)
  end
end

See the documentation for more information. Especially the Pdns::API::Endpoint. Most endpoints are scoped under either Pdns::API::Endpoints::Servers or Pdns::API::Endpoints::Zones (which is in turn scoped under Pdns::API::Endpoints::Servers). You can access the scoped endpoints by using the #with(id) method of an endpoint. It will be passed as a block variable.
