function New-F5Stack { <# .SYNOPSIS Automates the deployment of a new project for inbound access on a given domain name. .Description Creates a new node, new pool, new listening virtual server, client ssl profile, server ssl profile, switching irule, and ASM policy for given parameters. Applies the irule to the appropriate proxy VS. ======Does not currently apply SSLcleint profiles to main proxy routing VS and this must be done manually.====== .PARAMETER dns The dns name which we would like to open via the reverse proxy. .PARAMETER nodeIP The ip of the intenral node and or AWS instance in the VCD. Pass either IP or FQDN not both. .PARAMETER nodeFQDN The FQDN of the intenral node and or AWS instance in the VCD. Pass either IP or FQDN not both. .PARAMETER nodePort The internal port the node is listening on. .PARAMETER vsPort The port the virutal server will be listening on .PARAMETER vsIP The IP the virutal server will be configured to use. .PARAMETER sslClientProfile The name of the client profile you wish to create. May be omitted. Can specify the default clientssl profile as well. .PARAMETER sslServerProfile The name of the client profile you wish to create. May be omitted. Gernally the serverssl profile should simply be provided as this keep config to a minimum .PARAMETER certname Name of certificate to be attched to profile. In format something.com.crt .PARAMETER keyname Name of key to be attched to profile. In format something.com.key .PARAMETER asmPolicyName Used to specify and existing ASM policy to use as when doing multiple builds with the same policy. Should otherwise be left blank. .PARAMETER desc Description for each LTM object to be tagged into the description field. Should be the AWS_ID generally. .PARAMETER buildtype Switch to set the type of build required. HTTP or HTTPS are valid options. .Example New-F5Stack -dns funtimes.boozallencsn.com -nodeIP 10.194.55.109 -nodePort 80 -vsPort 443 -vsIP 1.1.1.256 -sslClientProfile funtimes.boozallencsn.com -desc AWS_309304096838 -certname funtimes.boozallencsn.com.crt -keyname funtimes.boozallencsn.com.key -buildtype HTTPS Create new node 10.194.55.109:80, new virtual server named funtimes.boozallencsn.com listening at 443, new pool pointed to new node, new ssl client profile, new irule, and new asm profile .NOTES Requires F5-LTM modules from github #> [CmdletBinding()] param( [Alias("DNS Name of instance")] [Parameter(Mandatory = $true)] [string]$dns = '', [Alias("Node IP")] [Parameter(Mandatory = $false)] [string]$nodeIP = '', [Alias("Node FQDN")] [Parameter(Mandatory = $false)] [string]$nodeFQDN = '', [Alias("Node Port ")] [Parameter(Mandatory = $true)] [string]$nodePort = '', [Alias("Virtual Destination Port")] [Parameter(Mandatory = $true)] [string]$vsPort = '', [Alias("VS IP")] [Parameter(Mandatory = $true)] [string]$vsIP = '', [Alias("Client SSL Profile")] [Parameter(Mandatory = $false)] [string]$sslClientProfile = '', [Alias("Server SSL Profile")] [Parameter(Mandatory = $false)] [string]$SSLServerProfile = '', [Alias("Cert Name")] [Parameter(Mandatory = $false)] [string]$certname = '', [Alias("Key Name")] [Parameter(Mandatory = $false)] [string]$keyname = '', [Alias("ASM")] [Parameter(Mandatory = $false)] [string]$asmPolicyName = '', [Alias("Description")] [Parameter(Mandatory = $false)] [string]$desc = '', [ValidateSet('HTTP','HTTPS')] [Parameter(Mandatory = $true)] [string]$buildtype = '' #Commenting out to add hardcoded options probably a bad idea #[ValidateSet('AWS_WSA_vs','AWS_WSA_redirect_vs')] #[Parameter(Mandatory = $true)] #[string]$wsa = '' ) begin { Check-F5Token switch ($buildtype) { "HTTP" { $ssl = $false #trim removes incompatiable wild card from valid *.something.com FQDNS $vsName = $dns.TrimStart('*.') + "_http" $nodeName = $dns.TrimStart('*.') $wsa = 'AWS_WSA_redirect_vs' $iruleDns = $dns break } "HTTPS" { $ssl = $true $vsName = $dns.TrimStart('*.') + "_https" $nodeName = $dns.TrimStart('*.') $wsa = 'AWS_WSA_vs' $iruleDns = $dns break } } }#end begin block process { Write-Output "Starting new build....." #New SSL Profiles try{ #skip if HTTP only build if($buildtype -eq "HTTPS"){ #Powershell makes this soo eloquent!
