How to Modify iRule and apply new iRule through API.

The usage information for the module is in the readme on Github. You need to establish your credentials, and then instantiate the BIG-IP.

$secpasswd = ConvertTo-SecureString "PlainTextPassword" -AsPlainText -Force
$mycreds = New-Object System.Management.Automation.PSCredential "username", $secpasswd
New-F5Session -LTMName "192.168.1.245" -LTMCredentials $mycreds

This of course assumes you are using basic auth instead of tokens.

Thanks Tiziano & Jason for your help. Does that mean to set\update the iRule i just need to include 'Set-iRule.Ps1' or 'Get-iRule' in my TFS release task and execute it ?

Thanks Again for your help and pointing me to right direction.

Yes, after instantiation you should be able to just run the script. Note the credentials line in the Set-iRule.ps1 srcipt.

However, please note I'm not sure exactly about the mechanics of TFS as I'm unfamiliar with the platform.

Thanks Jason for your guidance.

Hi Jason, The powershell "Set-iRule.ps1" does take few input parameter one of which is RuleContent, but in my case iRules are already available on virtual server just that i need to apply any one of them ?

I dont want create iRules everytime,inshort just pick any one and apply.

The iRules attribute is not a subcollection, so any update needs to be the complete list of iRules you want applied to that virtual server.
