Brooklyn Elasticsearch

A Pure Brooklyn YAML blueprint to deploy a cluster of Elasticsearch nodes.

Currently you can customize the following configuration:

• install.version: The version of elasticsearch to install
• elasticsearch.http.port: The port that Elasticsearch nodes will listen on for HTTP requests
• elasticsearch.tcp.port: The port that Elasticsearch nodes will listen on for TCP requests
• cluster.initial.size: The number of elasticsearch nodes to create
• elasticsearch.user: The username of the root elastic search user
• elasticsearch.password: The password for the root elastic search user

To create a cluster of Elasic search nodes with a single load balanced http entry point, you can put an NginX proxy in front of the entity with a blueprint like this:

location: my-location
name: Elastic Search Cluster
services:
- type: elasticsearch
  id: elasticsearch
  name: Elastic Search Nodes
- type: org.apache.brooklyn.entity.proxy.nginx.NginxController
  id: nginx
  name: Load Balancer (nginx)
  brooklyn.config:
    proxy.http.port: 9220
    loadbalancer.serverpool: $brooklyn:entity("elasticsearch")
    nginx.sticky: false
brooklyn.enrichers:
- type: org.apache.brooklyn.enricher.stock.Propagator
  brooklyn.config:
    producer: $brooklyn:entity("nginx")
    propagating:
    - main.uri
    - main.uri.mapped.subnet
    - main.uri.mapped.public
