What

Unit files to deploy an ElasticSearch cluster on CoreOS via Fleet.

Service discovery & registration is done via etcd.

[email protected] provides a dumb discovery service by registering an elasticsearch host if it should be up. [email protected] registers the service only if it is running.

A service & timer unit for elasticsearch curator is provided which does some housekeeping.

This script will pull down an S3 remote configuration before running any terraform actions. Assumes the following structure:

main.tf
terraform.cfg
env/dev/vars
env/staging/vars
env/whatever/vars
env/whatever/somefile.tf

This is a fork from the original CoreOS cloud formation template. It adds two EBS disks of 30G, mounted to /var/lib/docker.

This is intended to be used with an m3.large machine which comes with 30G of SSD.

The reason I add two of 30 and not one of 60 is because a BTRFS limitation.

You can use the "btrfs add" approach in the units to create a BTRFS raid.
