# DSC configuration for Pull Server using registration with enhanced security settings # The Sample_xDscWebServiceRegistrationWithEnhancedSecurity configuration sets up a DSC pull server that is capable for client nodes # to register with it and retrieve configuration documents with configuration names instead of configuration id # Prerequisite: Install a certificate in "CERT:\LocalMachine\MY\" store # For testing environments, you could use a self-signed certificate. (New-SelfSignedCertificate cmdlet could generate one for you). # For production environments, you will need a certificate signed by valid CA. # Registration only works over https protocols. So to use registration feature, a secure pull server setup with certificate is necessary # The Sample_MetaConfigurationToRegisterWithSecurePullServer register a DSC client node with the pull server # ======================================== Arguments ======================================== # $thumbprint = (New-SelfSignedCertificate -Subject $env:COMPUTERNAME).Thumbprint $registrationkey = [guid]::NewGuid() # ======================================== Arguments ======================================== # # =================================== Section DSC Client =================================== # configuration Sample_xDscWebServiceRegistrationWithSecurityBestPractices { param ( [string[]]$NodeName = 'localhost', [ValidateNotNullOrEmpty()] [string] $certificateThumbPrint, [Parameter(HelpMessage='This should be a string with enough entropy (randomness) to protect the registration of clients to the pull server.
