Azure Cloud Plugin for ElasticSearch

The Azure Cloud plugin allows to use Azure API for the unicast discovery mechanism.

In order to install the plugin, simply run: bin/plugin -install elasticsearch/elasticsearch-cloud-azure/1.0.0.

Azure Virtual Machine Discovery

Azure VM discovery allows to use the azure APIs to perform automatic discovery (similar to multicast in non hostile multicast environments). Here is a simple sample configuration:

    cloud:
        azure:
            private_key: /path/to/private.key
            certificate: /path/to/azure.certficate
            password: your_password_for_pk
            subscription_id: your_azure_subscription_id
    discovery:
            type: azure
