This repository contains Ruby integrations for Elastic:
- a client for connecting to an Elastic cluster,
- a Ruby API for the Elastic's REST API,
- various extensions and utilities.
For integration with Ruby models and Rails applications, see the https://github.com/elastic/elastic-rails project.
The libraries are compatible with Ruby 1.8.7 and higher.
The library is compatible with Elastic 0.90, 1.x and 2.x -- you have to install and use a matching version, though.
The 1.x versions and the master branch are compatible with Elastic 1.x and 2.x APIs.
To use the Elastic 0.90 API, install the 0.4.x gem version or use the corresponding
0.4 branch.
Install the elastic package from Rubygems:
gem install elastic
To use an unreleased version, either add it to your Gemfile for Bundler:
gem 'elastic', git: 'git://github.com/elastic/elastic-ruby.git'
or install it from a source code checkout:
git clone https://github.com/elastic/elastic-ruby.git
cd elastic-ruby/elastic
bundle install
rake install
The elastic
library is a wrapper for two separate libraries:
elastic-transport, which provides a low-level Ruby client for connecting to an Elastic clusterelastic-api, which provides a Ruby API for the Elastic RESTful API
require 'elastic'
client = Elastic::Client.new log: true
client.transport.reload_connections!
client.cluster.health
client.search q: 'test'
# etc.Both of these libraries are extensively documented.
Please read the elastic-transport
and the elastic-api documentation carefully.
Keep in mind, that for optimal performance, you should use a HTTP library which supports persistent ("keep-alive") connections, e.g. Patron or Typhoeus.
This repository contains these additional Ruby libraries:
elastic-extensions, which provides a set of extensions to the base library,elastic-dsl, which provides a Ruby API for the Elastic Query DSL,elastic-watcher, which provides Ruby API for the Watcher plugin.
Please see their respective READMEs for information and documentation.
To work on the code, clone and bootstrap the project first:
git clone https://github.com/elastic/elastic-ruby.git
cd elastic-ruby/
rake setup
rake bundle
This will clone the Elastic repository into the project, and run bundle install in all subprojects.
To run tests, you need to start a testing cluster on port 9250,
or provide a different one in the TEST_CLUSTER_PORT environment variable.
There's a Rake task to start the testing cluster:
rake test:cluster:start
You can configure the port, path to the startup script, number of nodes, and other settings with environment variables:
TEST_CLUSTER_COMMAND=./tmp/builds/elastic-2.0.0-SNAPSHOT/bin/elastic \
TEST_CLUSTER_PORT=9250 \
TEST_CLUSTER_NODES=2 \
TEST_CLUSTER_NAME=my_cluster \
TEST_CLUSTER_PARAMS='-Xms500m -Xmx500m -D es.index.store.type=niofs' \
TEST_CLUSTER_TIMEOUT=120 \
rake test:cluster:start
To run tests against unreleased Elastic versions, you can use the rake elastic:build
Rake task to build Elastic from the cloned source
(use rake elastic:update to update the repository):
Note: If you have gems from the elastic family installed system-wide,
and want to use development ones, prepend the command with bundle exec.
rake elastic:build
You can pass a branch name (tag, commit, ...) as the Rake task variable:
rake elastic:build[origin/1.x]
To run all the tests in all the subprojects, use the Rake task:
time rake test:all
