Install head tool for elasticsearch5 in a bucket

Elasticsearch 5.x has removed the concept of site plugins. The purpose of this KB is to show how you can still install and serve the head plugin as static objects from an S3 bucket.

Instructions

step-by-step guide:

1. Download the head plugin from https://support.cloud.caringo.com/tools/elasticsearch5-head.tgz

2. Install s3cmd , on CentOS/RHEL7 simply type yum install s3cmd and then s3cmd --configure to configure it.

3. Create an S3 bucket called "head" 

   s3cmd mb s3://head

4. Untar the head plugin locally

   cd head; tar xvzf elasticsearch5-head.tgz

5. Upload all the files to your S3 bucket

   s3cmd sync . s3://head --no-mime-magic

   now you can access it using http://FQDN/head/index.html
   For Example: http://s3.demo.sales.local/head/index.html

   You can also pre-populated the target elasticsearch node with the base_uri queryArgument

   For Example: http://s3.demo.sales.local/head/index.html?base_uri=http://172.30.2.234:9200

   Keep in mind that most browsers wont allow mixed content loading between SSL and HTTP (aka CORS) , and elasticsearch port 9200 is HTTP not SSL !!
   so for example this wont work: https://s3.demo.sales.local/head/index.html?base_uri=http://172.30.2.234:9200
