Question

We currently have a PreDeploy.ps1, Deploy.ps1, PostDeploy.ps1 scripts specific to web applications or window services. Every once in a while we need to have an extension file to customize the deployment process.

We plan to implement extension files using an underscore – something like:

Deploy.ps1

    if( Test-Path "_Deploy.ps1" )
{
    $extensionFile = Resolve-Path "_Deploy.ps1"
    PowerShell -File $extensionFile 
}

How can i pass currently scoped variables (variable name and value) to the extensionFile?

Answer 1

Well don’t start a new PowerShell instance. 🙂 Run the script in the current PowerShell instance e.g.:

& $extensionFile

If that $extensionFile needs to modify (or create) variables in the current scope then execute it like so:

. $extensionFile
