AWS Distributor - How to create a flexible SSM Distributor Package?

Question

I have created an AWS Systems Manager Distributor Package. It is very specific to my environment. I would like to generalize it. In the install.ps1 file I currently have:

msiexec /i mymsi.msi PARM1="TEST-1" PARM2="360fc9f925458cd2039a299" /qn /L*v myinstall.log

I would like to generalize this such that my install.ps1 file would look something like this:

msiexec /i mymsi.msi var1="{MYPARM1}" var2="{MYPARM2}" /qn /L*v myinstall.log

Then when performing the distribution, I would include MYPARM1, MYPARM2 as part of the distribution. This would allow a public distribution of the product to various customers who are provided values for MYPARM1, MYPARM2

I think these parameter values would go in the "Additional Arguments" section when using the AWS Console to Install the Distributor

Answer 1

This required reverse-engineering a third-party add-in:

1-within the *.ps1 files parameters are read. The parms must have a prefix of SSM

Example install.ps1 :

$MYPARM1=$env:SSM_MYPARM1
$MYPARM2=$env:SSM_MYPARM2
msiexec /i mymsi.msi var1=$MYPARM1 var2=$MYPARM2 /qn /L*v myinstall.log

2 - When supplying Additional Arguments to the AWS portal, provide the following

{
    "SSM_MYPARM1": "value1",
    "SSM_MYPARM2": "value2"
}

When the * .ps1 file is invoked, the values are read from Additional Arguments and can be used in the script.
