SRV Discovery Plugin for Elasticsearch

Use SRV records for Elasticsearch discovery, like the ones Consul provides.

Looking for a plugin that uses the Consul API directly? Check out lithiumtech/elasticsearch-consul-discovery.

Installation

Based on the version of Elasticsearch that you're running, pick the compatible plugin version (e.g. 1.5.1), then run this command:

bin/plugin install srv-discovery --url https://github.com/github/elasticsearch-srv-discovery/releases/download/1.5.1/elasticsearch-srv-discovery-1.5.1.zip

Verify that the plugin was installed:

$ bin/plugin -l
Installed plugins:
    - srv-discovery

$ curl localhost:9200/_cat/plugins?v
name  component             version type url
Pluto srv-discovery         ...     j

Compatibility

The SRV Discovery plugin is known to be compatible with these versions of Elasticsearch:

Elasticsearch SRV Discovery plugin
1.7.3 1.5.1
1.7.2 1.5.1
1.7.1 1.5.1
1.7.0 1.5.1
1.6.2 1.5.1
1.6.1 1.5.1
1.6.0 1.5.1
1.5.2 1.5.1
1.5.1 1.5.1
1.5.0 1.5.1

Configuration

Key Example Description
discovery.srv.query elasticsearch-9300.service.consul The query string to use when querying for SRV records.
discovery.srv.servers 127.0.0.1:8600 DNS Servers to contact. Can be an array or a comma-delimited string. Port numbers are optional.
discovery.srv.protocol tcp Which protocol to use. Options are tcp and udp. Default is tcp.

Note: Consul will return maximum 3 records when using UDP queries. All records are returned when using TCP.

Simple Example

discovery:
  type: srv
  srv:
    query: elasticsearch-9300.service.consul

Complex Example

discovery:
  type: srv
  srv:
    query: elasticsearch-9300.service.consul
    protocol: tcp
    servers:
      - 127.0.0.1:8600
      - 192.168.1.1

Development

To see the effects of a change on a real Elasticsearch instance, build the package and install it like so:

plugin="/Users/you/elasticsearch-<version>/bin/plugin"
name="srv-discovery"
zip="file:///Users/you/elasticsearch-srv-discovery/build/distributions/elasticsearch-srv-discovery-<version>.zip"

gradle distZip || exit 1
$plugin remove $name
$plugin install $name --url $zip
