Srvy
A rubygem to integrate SRV-based service discovery into your application
Installation
Add this line to your application's Gemfile:
gem 'srvy'
And then execute:
$ bundle
Or install it yourself as:
$ gem install srvy
Usage
$srvy = Srvy::Resolver.new # default configuration, using the locally configured resolver
# picks a single server by randomized with weight in the highest priority group
$srvy.get_single("db-slaves.mydomain.com") # => "mysql01.mydomain.com:3306"
# to get all services in the highest priority group
$srvy.get_many("memcache.mydomain.com") # => ["memcache01.mydomain.com:11211", "memcache02.mydomain.com:11211"]
# get all records, including lower priority (e.g. backup) services
$srvy.get_all("db.mydomain.com") # => ["db01.mydomain.com:3306", "db01-failover.mydomain.com:3306"]#TODO
I havent currently thought of a good api to signal to Srvy that you want to use lower priority services... currently the only way is to use get_all and pick the services out yourself.
