Function By { <# .SYNOPSIS Specify details about the DeploymentType for deployments defined in a PSDeploy.ps1 .DESCRIPTION Specify details about the DeploymentType for deployments defined in a PSDeploy.ps1 This is not intended to be used anywhere but in a *.PSDeploy.ps1 file. It is included here for intellisense support .PARAMETER DeploymentType The type of deployment you are defining. For example, a FileSystem deployment. See Get-PSDeploymentType for a list of valid deployment types. .PARAMETER Name An optional name for the deployment in this 'By' block. This would be needed if you wanted more than one 'By' block for a single DeploymentType. This is tacked on to the Deploy Name: DeployName-ByName. .PARAMETER Script Details on the deployment. You can include the following functions inside your By: - FromSource: The item(s) you are deploying. Required. - To: The target(s) you are deploying to. Required. - WithOptions: Any DeploymentType specific options .EXAMPLE # This is a complete PSDeploy.ps1 example including a By function Deploy DeployMyModule By FileSystem { FromSource 'MyModule' To 'C:\sc\MyModule' WithOptions @{ Mirror = $True } } } # This would deploy the folder 'MyModule' to C:\sc\MyModule. It would mirror (i.e. remove items that are not in the source) .EXAMPLE # This is a complete PSDeploy.ps1 example including a By function Deploy DeployMyModule By FileSystem { FromSource 'MyModule' To 'C:\sc\MyModule' WithOptions @{ Mirror = $True } } By FileSystem Tasks { FromSource 'Tasks' To 'C:\sc\Tasks' } } # This illustrates using two of the same DeploymentTypes, with different options and details. # We specify a name to ensure uniqueness of the resulting DeploymentName: DeployMyModule and DeployMyModule-Tasks # This would deploy the folder 'MyModule' to C:\sc\MyModule. It would mirror (i.e. remove items that are not in the source) # This would deploy the folder Tasks to C:\sc\Tasks, without mirroring. .LINK about_PSDeploy .LINK about_PSDeploy_Definitions .LINK https://github.com/RamblingCookieMonster/PSDeploy .LINK Deploy .LINK To .LINK FromSource .LINK Tagged .LINK WithOptions .LINK DependingOn .LINK Get-PSDeployment .LINK Get-PSDeploymentType .LINK Get-PSDeploymentScript #> [cmdletbinding(DefaultParameterSetName = 'NoName')] param( [parameter( Position = 0, Mandatory = $True)] [string]$DeploymentType, [parameter( ParameterSetName = 'Name', Position = 1, Mandatory = $False)] [string]$Name, [parameter( ParameterSetName = 'NoName', Position = 1, Mandatory = $true)] [parameter( ParameterSetName = 'Name', Position = 2, Mandatory = $true)] [ScriptBlock]$Script ) $Script:ThisBy = [pscustomobject]@{ DeploymentName = $null DeploymentType = $null Source = $null Targets = $null DeploymentOptions = $null Tags = $null Dependencies = $null PreScript = $null PostScript = $null } if( $PSCmdlet.ParameterSetName -eq 'Name') { $Name = "$($Script:ThisDeployment.DeploymentName)-$Name" } else { $Name = $Script:ThisDeployment.DeploymentName } $Namespace = @( $Script:Deployments | Where {$_.DeploymentType -eq $DeploymentType -and $_.Name -eq $Name} ) if($Namespace.Count -gt 0) { Write-Error "Could not add 'By $Name', please ensure your 'By' blocks have a unique name within their DeploymentType." } else { $Script:ThisBy.DeploymentName = $Name $Script:ThisBy.DeploymentType = $DeploymentType # Determine if task is calling FromSource (ps1 task type) or jut an arbitrary scriptblock (scriptblock task type) $CommandDetails = $script.ast.FindAll( {$args[0] -is [System.Management.Automation.Language.CommandAst]}, $true ) $Commands = Foreach($Command in $CommandDetails) { $Command.CommandElements[0].Value } # If this is a scriptblock (not calling fromsource), add scriptblock to DeploymentSource to call later... if($DeploymentType -eq 'Task' -and $Commands -notcontains 'FromSource') { Write-Verbose "Adding script to source: $($Script | Out-String)" $Script:ThisBy.Source = $Script } else { . $Script } # One might imagine a case where a deployment has a source or a target but not both. # So...
