ConfigServer

The simplest way to store YAML configuration and server it over HTTP

Installation

Add this line to your application's Gemfile:

gem 'config_server'

And then execute:

$ bundle

Or install it yourself as:

$ gem install config_server

Usage

To run the server you must have a configuration file first:

#config.yml

production:
  api:
    db_host: prod.mydb.com
    s3_bucket: some-bucket-prod
  nginx:
    server_name: www.me.prod

staging:
  api:
    db_host: staging.mydb.com
    s3_bucket: some-bucket-staging
  nginx:
    server_name: www.me.staging

Then create the following ruby file:

#my_configuration_server.rb

require 'config_server'

ConfigServer.start("config.yml")

and run bundle exec ruby my_configuration_server.rb

You can now query the server:

  1. In the first example we get the production db host for the api service
  2. In the second example we ask for a non existing key and get a 404 response
  3. In the third example we ask for a key which has a hash value. We get a JSON representation of it.

Usage Examples

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
