Script to call the Solr functionality from an Octopus step.

BlueGreenSolr.ps1

using module ".\BlueGreenSolrSettings.psm1"
using module ".\BlueGreenSolrSettingsMap.psm1"

<#
.SYNOPSIS
	Calls the Solr functions for SolrCloud CDCR to update a Live environment (with Octopus deploy).
	The .\BlueGreenSolrSettingsMap.psm1 file is used to map Octopus-defined variable values to 
	the .\BlueGreenSolrSettings.psm1 properties.

.PARAMETER startingReplication
	Boolean variable used to specify if replication is being started or if this is a pre-starting 
	event to change the direction of replication.

.PARAMETER reversing
	Boolean variable used to specify if the replication direction is being reversed or not. 
	This option will be false, unless a reversal deployment is being run. 
	In a reversal the roles used for pushing configs and starting replication are reversed.

.EXAMPLE
	Pushing config files to SolrCloud Zookeepers.
		.\BlueGreenSolr.ps1 -startingReplication $false -reversing $false
	Starting the replication process after the Zookeepers have received the configurations.
		.\BlueGreenSolr.ps1 -startingReplication $true -reversing $false
	Reverting a failed deploy and reverting zookeeper configs.
		.\BlueGreenSolr.ps1 -startingReplication $false -reversing $true
	Reverting a failed deploy, restarting replication.
		.\BlueGreenSolr.ps1 -startingReplication $true -reversing $true
