Function Get-PSDeployment { <# .SYNOPSIS Read a Deployment.yml file .DESCRIPTION Read a Deployment.yml file The resulting object contains these properties DeploymentSource = Path to the deployment.yml DeploymentName = Deployment name DeploymentAuthor = Optional deployment author DeploymentType = Type of deployment, must be defined in PSDeploy.yml DeploymentOptions = Options for this deploymenttype Source = Path to source from the local machine SourceType = Directory or file SourceExists = Whether we can test path against the local source Targets = One or more targets to deploy to. Tags = One or more tags associated with this deployment Dependencies = One or more DeploymentNames that this deployment depends on WithPreScript = One or more scripts to run before a deployment executes WithPostScript = One or more scripts to run after a deployment executes Raw = Raw definition for yaml deployments This is oriented around deployments from a Windows system. It's a poor schema that grew from a single use case. .PARAMETER Path Path to deployment.yml to parse .PARAMETER DeploymentRoot Assumed root of the deployment.yml for relative paths. Default is the parent of deployment.yml .PARAMETER Deployment Used in the background by Invoke-PSDeploy .PARAMETER Tags Only return deployments with all of the specified Tags (like -and, not -or) .EXAMPLE Get-PSDeployment C:\Git\Module1\Deployments.yml # Get deployments from a yml file .EXAMPLE Get-PSDeployment -Path C:\Git\Module1\Deployments.yml, C:\Git\Module2\Deployments.yml | Invoke-PSDeployment -Force # Get deployments from two files, invoke deployment for all .EXAMPLE Get-PSDeployment -Path C:\Git\Module1\My.PSDeploy.ps1 -Tags Prod, Azure # Get deployments from My.PSDeploy.ps1, including only those tagged both 'prod' and 'azure' .LINK about_PSDeploy .LINK https://github.com/RamblingCookieMonster/PSDeploy .LINK Invoke-PSDeployment .LINK Invoke-PSDeploy .LINK Get-PSDeploymentType .LINK Get-PSDeploymentScript #> [cmdletbinding(DefaultParameterSetName='File')] Param( [validatescript({Test-Path -Path $_ -PathType Leaf -ErrorAction Stop})] [parameter( ParameterSetName = 'File', Mandatory = $True)] [string[]]$Path, [string]$DeploymentRoot, [parameter( ParameterSetName = 'Deployment', Mandatory = $True)] [object[]]$Deployment, [string[]]$Tags ) #Resolve relative paths...
