using namespace System.Collections.Generic function Invoke-DBDeployAgentJob { <# .SYNOPSIS This function is designed to deploy SQL Agent jobs using variables that can customize the deployment for each server deployed to. .DESCRIPTION This function is designed to deploy SQL Agent jobs using variables that can customize the deployment for each server deployed to. .NOTES To signify custom variables in your script you will use the SqlCmd format of $(variable_name). Each one of these tokens will be replaced by variables that are provided in either the ServerVariables or the GlobalVariables. .PARAMETER ServerVariables The server variables define which server the job is deployed to, and what server specific variables there are. Any server variable that has the same name of a global variable will override the value for the global variable. The server variables are a nested HashTable, where the key of the top level HashTable is the server name, and the keys for the nested HashTable are the variable keys. NOTE: A variable must be supplied for all $(tokens) in the script. Example: $serverVariables = @{ "server1\instance1" = @{ key1 = "server1_value1" key2 = "server1_value2" } "server2\instance1" = @{ key1 = "server2_value1" key2 = "server2_value2" } "server3" = @{} } When deploying to server1/instance1 each instance of $(key1) will be replaced with server1_value1 and $(key2) will be replaced with server1_value2 within the job script. As server3 defines no variables, then only global variables will be used for its deployment. .PARAMETER AgentScriptFile The path to the sql agent job file. Invoke-DBSqlAgentScripter can be used to script agent jobs out, or you can script your own. This file must exist. The special key word "example" can be passed here, and the file /sql/SqlAgentJobExample.sql will be used. The job created will be named DeployAgentJobExample when using this. .PARAMETER GlobalVariables Global variables are default values for variables that can be used when you only wish to override the globals sometimes with certain servers. Example: $globalVariables = @{ Key1 = "globals value 1" Key2 = "globals value 2" } .PARAMETER Resources Resources are also a HashTable. The key of the resource is path to a valid zip file. It must be a zip file. Then the value of the HashTable is a UNC path to a folder. If the folder resides on each server, then use the substitution token <<server_name>> in the path, and the script will replace that token with the current server name. Example: $resources = @{ "c:\temp\SomeZipFile.zip" = "\\<<server_name>>\ShareName\Jobs\FolderName" "c:\temp\SomeZipFile2.zip" = "\\<<server_name>>\ShareName\Jobs\FolderName2" } .PARAMETER Credentials Specifies credentials to connect to the database with. If not supplied then a trusted connection will be used. The credentials used will be the same for all the server connections. .EXAMPLE An example showing multiple servers with the example job script. # global variables will be overwritten by ServerVariables with the same name $globalVariables = @{ Key1 = "globals value 1" Key2 = "globals value 2" } $serverVariables = @{ "server1\instance1" = @{ key1 = "server1_value1" key2 = "server1_value2" } "server2\instance1" = @{ key1 = "server2_value1" key2 = "server2_value2" } "server3" = @{} } Invoke-DBDeployAgentJob -GlobalVariables $globalVariables -ServerVariables $serverVariables -AgentScriptFile "example" -Verbose .EXAMPLE An example showing multiple servers with the example job script that also deploy resources to each server. Server3 in this case is also using a custom port. # global variables will be overwritten by ServerVariables with the same name $globalVariables = @{ Key1 = "globals value 1" Key2 = "globals value 2" } $serverVariables = @{ "server1\instance1" = @{ key1 = "server1_value1" key2 = "server1_value2" } "server2\instance1" = @{ key1 = "server2_value1" key2 = "server2_value2" } "server3,2866" = @{} } $resources = @{ "c:\temp\SomeZipFile.zip" = "\\<<server_name>>\ShareName\Jobs\FolderName" } Invoke-DBDeployAgentJob -GlobalVariables $globalVariables -ServerVariables $serverVariables -AgentScriptFile "example" -Resources $resources .NOTES If you need to use an $ in the sql that is NOT a token then you should replace the $ with $(dollar). Example: $(dollar)(ESCAPE_SQUOTE(SRVR) When deployed to the server this will revert to: $(ESCAPE_SQUOTE(SRVR) More info on SQL Agent Job tokens: https://learn.microsoft.com/en-us/sql/ssms/agent/use-tokens-in-job-steps?view=sql-server-ver16#sql-server-agent-tokens .LINK https://github.com/tcartwright/tcdbtools .NOTES Author: Tim Cartwright #> [CmdletBinding()] [Alias("Invoke-DBDeploySqlAgentJob")] param ( [Parameter(Mandatory = $true)] [ValidateScript({$_.Count -ge 1})] [HashTable]$ServerVariables, [Parameter(Mandatory = $true)] [ValidateScript({ $_.Name -ieq "example" -or $_.Exists })] [System.IO.FileInfo]$AgentScriptFile, [HashTable]$GlobalVariables, [HashTable]$Resources, [pscredential]$Credentials ) begin { $SqlCmdArguments = New-DBSqlCmdArguments -ServerInstance "--NA--" -Credentials $Credentials $variables = New-Object System.Collections.Generic.Dictionary"[string, string]" ([StringComparer]::CurrentCultureIgnoreCase) # this variable is ALWAYS added so that dollar signs can be encoded in the scripts and not interpreted as sqlcmd variables # EX, $(ESCAPE_SQUOTE(SRVR) should be written as $(dollar)(ESCAPE_SQUOTE(SRVR) so that it will be translated to the the desired result # it won't hurt anything if the variable is added twice $variables.Add("dollar", "$") | Out-Null foreach ($key in $GlobalVariables.Keys) { $variables.Add($key, $($GlobalVariables[$key])) | Out-Null } if ($AgentScriptFile.Name -ine "example") { Write-Information "Deploying job script $($AgentScriptFile.FullName)" $jobScript = Get-Content -Path $AgentScriptFile.FullName -Raw -Encoding ascii } else { Write-Information "Deploying job script SqlAgentJobExample.sql" $jobScript = GetSQLFileContent -fileName "SqlAgentJobExample.sql" } } process { foreach($serverName in $ServerVariables.Keys) { $SqlCmdArguments.ServerInstance = $serverName # strip off the instance name if one is there $hostName = ($serverName -split "\\|,", 2) | Select-Object -First 1 foreach ($key in $Resources.Keys) { $resource = $key $destination = ($Resources[$key] -ireplace "<<server_name>>", $hostName) if (-not (Test-Path $destination -PathType Container)) { New-Item -Path $destination -ItemType Directory -ErrorAction SilentlyContinue } Write-InformationColorized "Deploying $resource to $destination" -ForegroundColor Green Expand-Archive -Path $resource -DestinationPath $destination -Force } # set up the var object for the server and add the globals $serverVars = New-Object System.Collections.Generic.Dictionary"[string, string]" ([StringComparer]::CurrentCultureIgnoreCase) foreach ($dictKey in $variables.Keys) { $serverVars.Add($dictKey, $variables[$dictKey]) | Out-Null } # add all the server variables, overriding any globals of the same name foreach($key in $ServerVariables[$serverName].Keys) { $value = $($ServerVariables[$serverName][$key]) if (-not $serverVars.ContainsKey($key)) { $serverVars.Add($key, $value) | Out-Null } else { $serverVars[$key] = $value } } $sql = [System.Text.StringBuilder]::new() # Prepend the setvar statements to the job sql.
