consul-loader

Consul Loader is a simple gem to convert a yaml file into a series of consul keys and values. Consul Loader will traverse your yaml file and generate a key from the location of each value. For example you have a yaml file like the example below:

first: 'one'
api:
  eventsauce:
    stats_d_server_url: 'statsd:8125'

This would generate two consul keys:

If your yaml file contains an array of values then Consul Loader would convert this into a json formatted array. For example:

retry_intervals:
  - '1s'
  - '1m'
  - '15m'
  - '1h'
  - '1d'

Would result in the below consul key:

Consul Loader always checks the value of the existing key, if it matches the current key then this is not overwritten to ensure consul-template or any other clients watching the kv store will update incorrectly.

  loader = ConsulLoader::Loader.new(ConsulLoader::ConfigParser.new)
  loader.load_config './config', 'http://consul.myhost.com:8500'

  loader = ConsulLoader::Loader.new(ConsulLoader::ConfigParser.new)
  loader.load_config './config/myfile.yml', 'http://consul.myhost.com:8500'

first: 'one'
api:
  eventsauce:
    stats_d_server_url: 'statsd:8125'
    data_store:
      connection_string: 'mongodb://mongo/event-sauce'
      database_name: 'event-sauce'
    queue:
      connection_string: 'redis:6379'
      event_queue: 'event_queue'
      dead_letter_queue: 'dead_letter_queue'
    retry_intervals:
      - '1s'
      - '1m'
      - '15m'
      - '1h'
      - '1d'
