function Invoke-VSPackage { <# .SYNOPSIS Packages the local artifacts (local paths) that your AWS CloudFormation template references. .DESCRIPTION Packages the local artifacts (local paths) that your AWS CloudFormation template references. The command uploads local artifacts, such as source code for an AWS Lambda function or a Swagger file for an AWS API Gateway REST API, to an S3 bucket. The command returns a copy of your template, replacing references to local artifacts with the S3 location where the command uploaded the artifacts. .PARAMETER TemplateBody A JSON or YAML string containing the template body. .PARAMETER TemplateFile The path to the local file containing the template. .PARAMETER S3Bucket The name of the S3 bucket where this command uploads the artifacts that are referenced in your template. .PARAMETER S3Prefix A prefix name that the command adds to the artifacts' name when it uploads them to the S3 bucket. The prefix name is a path name (folder name) for the S3 bucket. .PARAMETER KMSKeyId The ID of an AWS KMS key that the command uses to encrypt artifacts that are at rest in the S3 bucket. .PARAMETER OutputTemplateFile The path to the file where the command writes the output AWS CloudFormation template. If you don't specify a path, the command writes the template to the standard output. .PARAMETER UseJson Indicates whether to use JSON as the format for the output AWS CloudFormation template. YAML is used by default (if cfn-flip is available). .PARAMETER Force Indicates whether to override existing files in the S3 bucket. Specify this flag to upload artifacts even if they match existing artifacts in the S3 bucket. .PARAMETER ProfileName The name of the configuration profile to deploy the stack with. Defaults to $env:AWS_PROFILE, if set. .FUNCTIONALITY Vaporshell #> [cmdletbinding(DefaultParameterSetName = "TemplateFile")] Param ( [parameter(Mandatory = $true,Position = 0,ParameterSetName = "TemplateBody",ValueFromPipeline = $true)] [String] $TemplateBody, [parameter(Mandatory = $true,Position = 0,ParameterSetName = "TemplateFile")] [ValidateScript( { Test-Path $_ })] [String] $TemplateFile, [parameter(Mandatory = $true,Position = 1)] [String] $S3Bucket, [parameter(Mandatory = $false)] [System.String] $S3Prefix, [parameter(Mandatory = $false)] [System.String] $KMSKeyId, [parameter(Mandatory = $false)] [System.String] $OutputTemplateFile, [parameter(Mandatory = $false)] [Switch] $UseJson, [parameter(Mandatory = $false)] [Alias("ForceUpload")] [Switch] $Force, [parameter(Mandatory = $false)] [String] $ProfileName = $env:AWS_PROFILE ) Begin { $prof = @{} if ($ProfileName) { $prof["ProfileName"] = $ProfileName } $typeHash = @{ "AWS::ApiGateway::RestApi" = "BodyS3Location" "AWS::Lambda::Function" = "Code" "AWS::Serverless::Function" = "CodeUri" "AWS::Serverless::Api" = "DefinitionUri" "AWS::ElasticBeanstalk::ApplicationVersion" = "SourceBundle" "AWS::CloudFormation::Stack" = "TemplateUrl" } $s3Params = @{} if ($S3Prefix) { $s3Params["BucketName"] = "$($S3Bucket)/$($S3Prefix)" $baseUrl = "$($S3Bucket)/$($S3Prefix)" } else { $s3Params["BucketName"] = $S3Bucket $baseUrl = $($S3Bucket) } if ($KMSKeyId) { $s3Params["KMSKeyId"] = $KMSKeyId } try { Write-Verbose "Checking if bucket '$S3Bucket' exists" $bucketLoc = Get-VSS3BucketLocation -BucketName "$S3Bucket" @prof -Verbose:$false Write-Verbose "Bucket '$S3Bucket' found in $($bucketLoc.Value)" } catch { if ($Force) { Write-Verbose "Creating new bucket '$S3Bucket'" New-VSS3Box -BucketName "$S3Bucket" @prof -Verbose:$false } else { $PSCmdlet.ThrowTerminatingError($_) } } } Process { Add-Type -AssemblyName "System.IO.Compression.Filesystem" if ($PSCmdlet.ParameterSetName -eq "TemplateFile") { Write-Verbose "Getting TemplateBody from TemplateFile path" $templateFilePath = (Resolve-Path $TemplateFile).Path $tempParent = (Get-Item $templateFilePath).Directory.FullName $TemplateBody = [System.IO.File]::ReadAllText($templateFilePath) } $tempPSON = Import-Vaporshell -TemplateBody $TemplateBody $resourceIds = $tempPSON.Resources | Get-Member -MemberType NoteProperty | Select-Object -ExpandProperty Name foreach ($res in $resourceIds) { $Resource = $tempPSON.Resources.$res try { $propName = $typeHash["$($Resource.Type)"] if ($propName -and $Resource.Properties.$propName) { Write-Verbose "Checking '$($Resource.Type)' resource --- property '$($propName)'" if (($Resource.Properties.$propName -notlike "s3://*") -and ($Resource.Properties.$propName -notlike "http*")) { $found = $true if (Test-Path ("$tempParent\$($Resource.Properties.$propName.TrimStart('.'))")) { $filePath = (Resolve-Path "$tempParent\$($Resource.Properties.$propName.TrimStart('.'))").Path Write-Verbose "File found in template directory at: $filePath" } elseif (Test-Path $Resource.Properties.$propName) { $filePath = (Resolve-Path $Resource.Properties.$propName).Path if ($filePath -like "$($pwd.Path)*") { Write-Verbose "File found in current working directory at: $filePath" } else { Write-Verbose "File found at: $filePath" } } else { $found = $false } if ($found) { $fileInfo = Get-Item $filePath if ($fileInfo.PSIsContainer) { if ($S3Prefix) { $key = "$($S3Prefix)/$($fileInfo.BaseName).zip" } else { $key = "$($fileInfo.BaseName).zip" } $outFile = Join-Path $fileInfo.Parent.FullName $key if (Test-Path $outFile) { Remove-Item $outFile -Force } [System.IO.Compression.Zipfile]::CreateFromDirectory($filePath,$outFile) } else { if ($S3Prefix) { $key = "$($S3Prefix)/$($fileInfo.Name)" } else { $key = "$($fileInfo.Name)" } $outFile = $filePath } if ($Force) { Write-Verbose "Uploading object!" $obj = New-VSS3Object -Key $key -FilePath $outFile @s3Params @prof -Verbose:$false } else { Write-Verbose "Checking if object exists in bucket" $existsMeta = Get-VSS3ObjectMetadata -BucketName $baseUrl -Key $key -ErrorAction SilentlyContinue -Verbose:$false if (!$existsMeta) { Write-Verbose "Object not found -- uploading!" $obj = New-VSS3Object -Key $key -FilePath $outFile @s3Params @prof -Verbose:$false } elseif ($existsMeta.ContentLength -eq (Get-Item $outFile).Length) { Write-Warning "Object '$key' already exists in bucket and is the same size.
