function Initialize-SRDSC { <# .Description Initalize-SRDSC is used for onboarding the ScriptRunner Server into DSC. It performs the following tasks: 1. Installs the DSC Pull Server. 2. Downloads and Install's Datum onto the ScriptRunner Server (DSC Toolbox). 3. Sets SRDSC Configuration setting key properties that are used by the SRDSC Build Scripts. 4. Copies SRDSC Scripts into the ScriptRunner repository (in ProgramData). 5. Creates ScriptRunner Service Account Credential. 6. Creates ScriptRunner Local Machine Target with the DSC Service Account Credential. 7. Adds Start-SRDSCConfiguration and Publish-SRActionScript scripts into ScriptRunner and configures the target and sets a reoccuring schedule. To initialize the script requires a number of parameters that are needed for execution. These are: -DatumModulePath: This is the destination path where the Datum Module is to be installed. -PullWebServerPath: This is the destination path of the IIS instance (C:\Inetpub\). -ScriptRunnerServerPath: The directory path of the ScriptRunner Script Repository (Usually Located at C:\ProgramData\). -ScriptRunnerURL: The URL to the ScriptRunner server. -ScriptRunnerSACredential: A username/password used by ScriptRunner to Execute the ScriptRunner Script. -PFXCertificatePath: (Used for the ScriptRunner Pull Server) If a custom SSL certificate is required, the path to that certificate is specified. -PFXCertificatePassword: The Export password for the custom SSL certificate. -UseSelfSignedCertificate: (Used for the ScriptRunner Pull Server) Use a Self-Signed certificate for the DSC Pull Server. .PARAMETER DatumModulePath This is the destination path where the Datum Module is to be installed. .PARAMETER PullWebServerPath This is the destination path of the IIS instance (C:\Inetpub\). .PARAMETER ScriptRunnerServerPath The directory path of the ScriptRunner Script Repository (Usually Located at C:\ProgramData\). .PARAMETER ScriptRunnerURL The URL to the ScriptRunner server. .PARAMETER ScriptRunnerSACredential A username/password used by ScriptRunner to Execute the ScriptRunner Script. .PARAMETER PFXCertificatePath (Used for the ScriptRunner Pull Server) If a custom SSL certificate is required, the path to that certificate is specified. .PARAMETER PFXCertificatePassword The Export Password for the custom SSL certificate. .PARAMETER UseSelfSignedCertificate (Used for the ScriptRunner Pull Server) Use a Self-Signed certificate for the DSC Pull Server. .EXAMPLE Create a DSC Pull Server (installed at C:\Inetpub) on the local ScriptRunner server (http://SCRIPTRUNNER01/', with a custom Certificate located at C:\MyCertificate.pfx.
