Add-FnJoin

SYNOPSIS

Adds the intrinsic function “Fn::Join” to a resource property

SYNTAX

Add-FnJoin [[-Delimiter] <String>] [-ListOfValues] <Object[]> [<CommonParameters>]

DESCRIPTION

The intrinsic function Fn::Join appends a set of values into a single value, separated by the specified delimiter. If a delimiter is the empty string, the set of values are concatenated with no delimiter.

EXAMPLES

EXAMPLE 1

Add-FnSelect -Index 2 -ListOfObjects (Add-FnSplit -Delimiter "," -SourceString (Add-FnImportValue -ValueToImport "AccountSubnetIds"))

When the template is exported, this will convert to: {“Fn::Select”:[“2”,{“Fn::Split”:[”,”,{“Fn::ImportValue”:”AccountSubnetIds”}]}]}

PARAMETERS

-Delimiter

The value you want to occur between fragments. The delimiter will occur between fragments only. It will not terminate the final value.
