Terraform and AWS SSM send-command parameter passing issue

[Brian Walsh]

I am using AWS SSM send-command to run a PowerShell script on an AWS instance.

The following commanad works fine in a command shell but when called in Terraform gets an error.

aws ssm send-command --instance-ids ${self.id} --document-name AWS-RunPowerShellScript --parameters commands='C:\\Installers\\bootstrap_test.ps1 test' --output-s3-bucket-name ellucian-ecrm-lab --output-s3-key-prefix bootstraplogsst'

when called in Terraform using:

  provisioner "local-exec" {

    command = "aws ssm send-command --instance-ids ${self.id} --document-name AWS-RunPowerShellScript --parameters commands='C:\\Installers\\bootstrap_test.ps1 test' --output-s3-bucket-name ellucian-ecrm-lab --output-s3-key-prefix bootstraplogs"

  }

The error returned is:

exit status 255. Output: usage: aws [options] <command> <subcommand> [<subcommand> ...] [parameters]

To see help text, you can run:

  aws help

  aws <command> help

  aws <command> <subcommand> help

Unknown options: test'

So I don't thing Terraform is parsing the string the way AWS needs it. what can I do to format this string correctly in Terraform?

Thanks!
