If the build has been customized then the resulting machine image may no longer be compatible with the provided CloudFormation template. Compatability can in some cases be restored by making corresponding modifications to the CloudFormation template. The ID should start with 'ami-'. |
 | **Optional user inline command** | Provide an optional inline PowerShell command to run on machine launch. For example, to set an environment variable CLOUD=AWS, use this command excluding the angle brackets: \<[System.Environment]::SetEnvironmentVariable("CLOUD","AWS", "Machine");>. You can use either double quotes or two single quotes. To run an external script, use this command excluding the angle brackets: \<Invoke-WebRequest "https://www.example.com/script.ps1" -OutFile script.ps1; .\script.ps1>. Find the logs at '$Env:ProgramData\MathWorks\startup.log'. |
