# Copyright (c) Microsoft Corporation. # Licensed under the MIT License. function Start-SdnCertificateRotation { <# .SYNOPSIS Performs a controller certificate rotate operation for Network Controller Northbound API, Southbound communications and Network Controller nodes. .PARAMETER Credential Specifies a user account that has permission to perform this action. The default is the current user. .PARAMETER NcRestCredential Specifies a user account that has permission to access the northbound NC API interface. The default is the current user. .PARAMETER CertPath Path directory where certificate(s) .pfx files are located for use with certificate rotation. .PARAMETER GenerateCertificate Switch to determine if certificate rotate function should generate self-signed certificates. .PARAMETER CertPassword SecureString password for accessing the .pfx files, or if using -GenerateCertificate, what the .pfx files will be encrypted with. .PARAMETER NotAfter Expiration date when using -GenerateCertificate. If ommited, defaults to 3 years. .PARAMETER CertRotateConfig The Config generated by New-SdnCertificateRotationConfig to include NC REST certificate thumbprint and node certificate thumbprint. .PARAMETER Force Switch to force the rotation without being prompted, when Service Fabric is unhealthy. #> [CmdletBinding(DefaultParameterSetName = 'GenerateCertificate')] param ( [Parameter(Mandatory = $true, ParameterSetName = 'Pfx')] [Parameter(Mandatory = $true, ParameterSetName = 'GenerateCertificate')] [Parameter(Mandatory = $true, ParameterSetName = 'CertConfig')] [System.Management.Automation.PSCredential] [System.Management.Automation.Credential()] $Credential, [Parameter(Mandatory = $false, ParameterSetName = 'Pfx')] [Parameter(Mandatory = $false, ParameterSetName = 'GenerateCertificate')] [Parameter(Mandatory = $false, ParameterSetName = 'CertConfig')] [System.Management.Automation.PSCredential] [System.Management.Automation.Credential()] $NcRestCredential = [System.Management.Automation.PSCredential]::Empty, [Parameter(Mandatory = $true, ParameterSetName = 'Pfx')] [System.String]$CertPath, [Parameter(Mandatory = $true, ParameterSetName = 'GenerateCertificate')] [Switch]$GenerateCertificate, [Parameter(Mandatory = $true, ParameterSetName = 'Pfx')] [Parameter(Mandatory = $true, ParameterSetName = 'GenerateCertificate')] [System.Security.SecureString]$CertPassword, [Parameter(Mandatory = $false, ParameterSetName = 'GenerateCertificate')] [datetime]$NotAfter = (Get-Date).AddYears(3), [Parameter(Mandatory = $true, ParameterSetName = 'CertConfig')] [hashtable]$CertRotateConfig, [Parameter(Mandatory = $false, ParameterSetName = 'Pfx')] [Parameter(Mandatory = $false, ParameterSetName = 'GenerateCertificate')] [Parameter(Mandatory = $false, ParameterSetName = 'CertConfig')] [switch]$Force ) # ensure that the module is running as local administrator $elevated = ([Security.Principal.WindowsPrincipal] [Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole]::Administrator) if (-NOT $elevated) { throw New-Object System.Exception("This function requires elevated permissions.
