It is invoked inside 'Environment' element. .DESCRIPTION It can be used to override default ServerRole values per step. .PARAMETER Name Name of the server role. .PARAMETER ScriptBlock Script block to use for this step. If not specified, DSC configuration/function named $Name will be invoked with default parameters. .PARAMETER RequiredPackages List of packages that will be copied to remote server before running actual steps. .PARAMETER RunRemotely If set then each step is run remotely (on nodes defined in $ServerConnections, or on specified $RunOn node). .PARAMETER RunOn Defines on which machine the step will run. .PARAMETER RebootHandlingMode Specifies what to do when a reboot is required by DSC resource: - **None** (default) - don't check if reboot is required - leave it up to DSC (by default it stops current step, but next configurations will run) - **Stop** - stop and fail the deployment - **RetryWithoutReboot** - retry several times without reboot - **AutoReboot** - reboot the machine and continue deployment Note that any setting apart from 'None' will cause output messages not to log in real-time. .PARAMETER Enabled Defines whether the step is enabled (if $false, the step will not run). .EXAMPLE Environment Default { ServerRole Web -Steps 'config1', 'config2' -RequiredPackages 'all' Step config1 -RequiredPackages 'package1' -RunRemotely } #> [CmdletBinding()] [OutputType([void])] param( [Parameter(Mandatory=$true)] [string] $Name, [Parameter(Mandatory=$false)] [scriptblock] $ScriptBlock, [Parameter(Mandatory=$false)] [object] $RequiredPackages, [Parameter(Mandatory=$false)] [switch] $RunRemotely, [Parameter(Mandatory=$false)] [string] $RunOn, [Parameter(Mandatory=$false)] #[ValidateSet($null, 'None', 'Stop', 'RetryWithoutReboot', 'AutoReboot')] [object] $RebootHandlingMode, [Parameter(Mandatory=$false)] [object] $Enabled ) if ((Test-Path variable:Env_Name) -and $Env_Name) { $stepsDef = $Global:Environments[$Env_Name].Steps if (!$stepsDef.Contains($Name)) { $stepsDef[$Name] = @{ Name = $Name } } $stepSettings = $stepsDef[$Name] if ($PSBoundParameters.ContainsKey('ScriptBlock')) { $stepSettings.ScriptBlock = $ScriptBlock } if ($PSBoundParameters.ContainsKey('RequiredPackages')) { $stepSettings.RequiredPackages = $RequiredPackages } if ($PSBoundParameters.ContainsKey('RunOn')) { $stepSettings.RunOn = $RunOn } if ($PSBoundParameters.ContainsKey('RunRemotely')) { $stepSettings.RunRemotely = $RunRemotely } if ($PSBoundParameters.ContainsKey('RebootHandlingMode')) { $stepSettings.RebootHandlingMode = $RebootHandlingMode } if ($PSBoundParameters.ContainsKey('Enabled')) { $stepSettings.Enabled = $Enabled } } else { throw "'Step' function cannot be invoked outside 'Environment' function (invalid invocation: 'Step $Name')." } } # this is for backward compatibility Set-Alias ConfigurationSettings Step Set-Alias StepSettings Step |
