function New-EswLoadBalancerConfig { <# .SYNOPSIS Adds a probe and rule to an existing internal or external load balancer. .DESCRIPTION Adds a probe and rule to an existing internal or external load balancer. .PARAMETER LoadBalancerName The name of the Azure load balancer you wish to configure. .PARAMETER ResourceGroupName The Azure resource group name that the load balancer is in. .PARAMETER Name The name of the probe/rule you wish to create. The convention is that they will both have the same name. .PARAMETER Port The port you want to create the rule for. .PARAMETER ProbePath The path of the probe you wish to create. The default is '/Probe'. .PARAMETER Force Force the re-configuration of both the probe and the rule. .EXAMPLE New-EswLoadBalancerConfig -LoadBalancerName 'test-lb' -ResourceGroupName 'test-rg' -Name 'test' -Port 999 Will create a 'test' probe and rule for port '999' on the 'test-lb' load balancer in the 'test-rg' resource group. .FUNCTIONALITY Configures rules on load balancers. #> [CmdletBinding()] param ( [parameter(Mandatory=$true, Position=0)] [string] $LoadBalancerName, [parameter(Mandatory=$true, Position=1)] [string] $ResourceGroupName, [parameter(Mandatory=$true, Position=2)] [string] $Name, [parameter(Mandatory=$true, Position=3)] [string] $Port, [string] $ProbePath = "/Probe", [switch] $Force ) $lbRefresh = Get-AzureRmLoadBalancer -Name $LoadBalancerName -ResourceGroupName $ResourceGroupName $rule = $null $probe = $null try { $rule = ($lb.LoadBalancingRules | ? { $_.Name -eq $Name })[0] } catch {} try { $probe = ($lbRefresh.Probes | ? { $_.Name -eq $Name })[0] } catch {} if($rule -or $probe -and $Force.IsPresent) { $lbRefresh | Remove-AzureRmLoadBalancerRuleConfig -Name $Name | Remove-AzureRmLoadBalancerProbeConfig -Name $Name | Set-AzureRmLoadBalancer > $null $lbRefresh = Get-AzureRmLoadBalancer -Name $LoadBalancerName -ResourceGroupName $ResourceGroupName $rule = $null $probe = $null } if($probe -eq $null) { $lbRefresh | Add-AzureRmLoadBalancerProbeConfig -Name "$Name" ` -Protocol Http ` -Port $Port ` -RequestPath $ProbePath ` -IntervalInSeconds 30 ` -ProbeCount 2 > $null } if($rule -eq $null) { $lbRefresh | Add-AzureRmLoadBalancerRuleConfig -Name "$Name" ` -Protocol Tcp ` -ProbeId ($lbRefresh.Probes | ? { $_.Name -eq $Name})[0].Id ` -FrontendPort $Port ` -BackendPort $Port ` -FrontendIpConfigurationId $lbRefresh.FrontendIpConfigurations[0].Id ` -BackendAddressPoolId $lbRefresh.BackendAddressPools[0].Id > $null } $lbRefresh | Set-AzureRmLoadBalancer > $null } |
