function Update-DBOConfig { <# .SYNOPSIS Updates configuration file inside the existing DBOps package .DESCRIPTION Overwrites configuration file inside the existing DBOps package with the new values provided by user .PARAMETER Path Path to the existing DBOpsPackage. Aliases: Name, FileName, Package .PARAMETER ConfigurationFile A path to the custom configuration json file Alias: ConfigFile .PARAMETER Configuration Hashtable containing several configuration items at once Alias: Config .PARAMETER ConfigName Name of the configuration item to update .PARAMETER Value Value of the parameter specified in -ConfigName .PARAMETER Variables Hashtable with variables that can be used inside the scripts and deployment parameters. Proper format of the variable tokens is #{MyVariableName} Can also be provided as a part of Configuration hashtable: -Configuration @{ Variables = @{ Var1 = ...; Var2 = ...}} .PARAMETER Confirm Prompts to confirm certain actions .PARAMETER WhatIf Shows what would happen if the command would execute, but does not actually perform the command .EXAMPLE # Update a single parameter in the configuration file of the Package.zip package Update-DBOConfig Package.zip -ConfigName ApplicationName -Value 'MyApp' .EXAMPLE # Update several configuration parameters at once using a hashtable Update-DBOConfig Package.zip -Configuration @{'ApplicationName' = 'MyApp'; 'Database' = 'MyDB'} .EXAMPLE # Update parameters based on the contents of the json file myconfig.json Update-DBOConfig Package.zip -ConfigurationFile 'myconfig.json' .EXAMPLE # Specifically update values of the Variables parameter Update-DBOConfig Package.zip -Variables @{ foo = 'bar' } #> [CmdletBinding(DefaultParameterSetName = 'Value', SupportsShouldProcess = $true)] Param ( [Parameter(Mandatory = $true, ValueFromPipeline = $true, Position = 1)] [Alias('FileName', 'Name', 'Package')] [string[]]$Path, [Parameter(ParameterSetName = 'Value', Mandatory = $true, Position = 2 )] [ValidateSet('ApplicationName', 'SqlInstance', 'Database', 'DeploymentMethod', 'ConnectionTimeout', 'ExecutionTimeout', 'Encrypt', 'Credential', 'Username', 'Password', 'SchemaVersionTable', 'Silent', 'Variables' )] [string]$ConfigName, [Parameter(ParameterSetName = 'Value', Mandatory = $true, Position = 3 )] [AllowNull()][object]$Value, [Parameter(ParameterSetName = 'Hashtable', Mandatory = $true, Position = 2 )] [Alias('Config')] [hashtable]$Configuration, [Parameter(ParameterSetName = 'File', Mandatory = $true, Position = 2 )] [Alias('ConfigFile')] [string]$ConfigurationFile, [Parameter(ParameterSetName = 'Variables', Mandatory = $true, Position = 2 )] [Parameter(ParameterSetName = 'Hashtable')] [Parameter(ParameterSetName = 'File')] [AllowNull()][hashtable]$Variables ) begin { } process { foreach ($pFile in (Get-Item $Path)) { if ($package = [DBOpsPackage]::new($pFile.FullName)) { $config = $package.Configuration Write-PSFMessage -Level Verbose -Message "Assigning new values to the config" if ($PSCmdlet.ParameterSetName -eq 'Value') { $newConfig = @{ $ConfigName = $Value } } elseif ($PSCmdlet.ParameterSetName -eq 'Hashtable') { $newConfig = $Configuration } elseif ($PSCmdlet.ParameterSetName -eq 'File') { $newConfig = (Get-DBOConfig -Path $ConfigurationFile).AsHashtable() } #Overriding Variables if ($Variables) { if ($PSCmdlet.ParameterSetName -ne 'Variables') { $newConfig.Remove('Variables') } $newConfig += @{ Variables = $Variables} } Write-PSFMessage -Level Verbose -Message "Saving configuration in the DBOpsPackage object" $config.Merge($newConfig) if ($pscmdlet.ShouldProcess($package, "Updating the package file")) { $config.Alter() } } } } end { } } |
