Function Deploy-GitOpsBuild { <# .SYNOPSIS Compares each file in the build directory with its representation in the destination directory and copies the build directory file over if the destination file does not match. .DESCRIPTION The 'Deploy-GitOpsBuild' function check each file in the build directory against it's file in the destination directory. It checks for the file hash of the Destination file. If the file is there and the hash matches the Build hash, the file is not copied. Otherwise, the file is copied. .PARAMETER Build The Directory that will be parsed and copied from. .PARAMETER Destination The Directory that will be parsed and copied to. .PARAMETER Source Not Used in this function. Added for splatting purposes. .PARAMETER ToSession Session where the Destination can be found. Can be null to represent local. .INPUTS System.IO.DirectoryInfo can be piped into Build. .OUTPUTs None #> [CmdletBinding(SupportsShouldProcess = $true)] param( [Parameter(Mandatory = $true, ValueFromPipeline = $true)] [ValidateScript( { Test-Path $_ -PathType Container })] [String] $Build, [ValidateScript( { Test-Path $_ -IsValid -PathType Container })] [String] $Destination, [System.Management.Automation.Runspaces.PSSession] $ToSession, [String] $Source ) Process { $CopyParams = @{} $InvCmdParams = @{} If ($PSBoundParameters['ToSession']) { Write-Verbose "Using $($ToSession | Select-Object -Property * | ConvertTo-Json)" $CopyParams.ToSession = $ToSession $InvCmdParams.Session = $ToSession } $BuildDirectory = Get-Item -Path $Build If (-not $(Invoke-Command -ScriptBlock { Test-Path $using:Destination } @InvCmdParams)) { Write-Verbose "Creating $Destination directory" Invoke-Command -ScriptBlock { New-Item $using:Destination -ItemType Directory } @InvCmdParams | Out-Null } $DestinationDirectory = Invoke-Command -ScriptBlock { Get-Item $using:Destination } @InvCmdParams ForEach ($BuildFile in $(Get-ChildItem $BuildDirectory -Recurse -File)) { $DestinationFile = @{ FullName = Join-Path -Path $DestinationDirectory.FullName -ChildPath $BuildFile.FullName.Replace($BuildDirectory.FullName,"") Directory = Join-Path -Path $DestinationDirectory.FullName -ChildPath $BuildFile.Directory.Fullname.Replace($BuildDirectory.FullName, "") } $BuildFileHash = Get-FileHash $BuildFile $DestinationFileHash = Invoke-Command -ScriptBlock { Get-FileHash $using:DestinationFile.FullName -ErrorAction SilentlyContinue } @InvCmdParams If ($DestinationFileHash -and ($BuildFileHash.Hash -eq $DestinationFileHash.Hash)) { Write-Verbose "$($DestinationFileHash.Path) hash matches $($BuildFileHash.Path) hash, not copying." } Else { Write-Verbose "Copying $($BuildFile.FullName) to $($DestinationFile.FullName)" if (-Not $(Invoke-Command -ScriptBlock { Test-Path $using:DestinationFile.Directory } @InvCmdParams)) { Write-Verbose "Creating $($DestinationFile.Directory) directory" Invoke-Command -ScriptBlock { New-Item $using:DestinationFile.Directory -ItemType Directory } @InvCmdParams | Out-Null } Copy-Item $BuildFile -Destination $DestinationFile.FullName @CopyParams } } } } |
