I see that there a several built-in functions available in HCL2, but is there a way to create one for use within the build
block?
As an example, my template has a couple PowerShell provisioners separated by a windows-restart
provisioner. Each of the PowerShell provisioners runs a script that is stored on an Azure file share that is mapped using New-PSDrive
.
Mapping the drive is the first thing done inside the build
block, but it has to be done again after the restart. Rather than duplicate the relevant code, I’d like to be able to define it in one place and refer to it in each provisioner
block.
Does packer support this as a user-defined function or other built-in feature?
