This uses terraform's template_file resource to generate a yaml properties file for serverspec to use.

create the Rakefile in your terraform project root
create a spec directory and put spec_helper.rb in it
create the templates/properties.tmpl.yml file
create the serverspec.tf
terraform apply

tests

Tests will be matched based on roles defined for a given node.

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

	#!/bin/bash
	# configures bash prompt based on current kubernetes cluster context and namespace
	# based on https://pracucci.com/display-the-current-kubelet-context-in-the-bash-prompt.html

	__kube_ps1()
	{
	CONTEXT=$(kubectl config view \| grep current-context \| awk '{ print $NF }' \| awk -F '.' '{ print $1 }')
	NS=$(kubectl config view $(kubectl config current-context) \| grep namespace \| awk '{ print $2 }')
	if [ -n "$CONTEXT" ]; then
	echo "[${CONTEXT}][${NS}]"
