Problem this snippet solves:
To report an issue with the F5-LTM or F5-BIGIP modules, please use the Issues sections of the GitHub repos (here and here) instead of commenting here. Thanks!
This PowerShell module uses the iControlREST API to manipulate and query pools, pool members, virtual servers, and iRules. It aims to support version 11.5.1 and higher, and to conform to the schedule for technical support of versions, though this may eventually prove to become difficult.
The module currently includes some functionality that, strictly speaking, is outside the scope of the LTM module. Hence, there is an active effort to wrap this LTM module into a larger BIG-IP module, and relocate that functionality elsewhere within that parent module, as well as expand the scope of functionality to include BIG-IP DNS (formerly GTM) and possibly other areas. Both the LTM module and the parent BIG-IP module are projects on github. Please use these projects to report any issues you discover. Thanks!
The module contains the following functions.
Get-CurrentConnectionCount (deprecated; use Get-PoolMemberStats | Select-Object -ExpandProperty 'serverside.curConns')
Get-F5Session (will be deprecated in future versions. use New-F5Session)
Get-iRuleCollection (deprecated; use Get-iRule)
Get-PoolList (deprecated; use Get-Pool)
Get-PoolMemberCollection (deprecated; use Get-PoolMember)
Get-PoolMemberDescription (deprecated; use Get-PoolMember)
Get-PoolMemberIP (deprecated; use Get-PoolMember)
Get-PoolMembers (deprecated; use Get-PoolMember)
Get-PoolMemberStatus (deprecated; use Get-PoolMember)
Get-VirtualServeriRuleCollection (deprecated; use Get-VirtualServer | Where rules | Select -ExpandProperty rules)
Get-VirtualServerList (deprecated; use Get-VirtualServer)
Set-PoolLoadBalancingMode (deprecated; use Set-Pool)
How to use this snippet:
To use the module, click 'Download Zip', extract the files, and place them in a folder named F5-LTM beneath your PowerShell modules folder. By default, this is %USERPROFILE%\Documents\WindowsPowerShell\Modules. The WindowsPowerShell and Modules folders may need to be created.
You will most likely need to unblock the files after extracting them. Use the Unblock-File PS cmdlet to accomplish this.
The Validation.cs class file (based on code posted by Brian Scholer) allows for using the REST API with LTM devices with self-signed SSL certificates.
Nearly all of the functions require an F5 session object as a parameter, which contains the base URL for the F5 LTM and a credential object for a user with privileges to manipulate the F5 LTM via the REST API. Use the New-F5session function to create this object. This function expects the following parameters:
The name or IP address of the F5 LTM device
A credential object for a user with rights to use the REST API
An optional TokenLifespan value for extending the life of the authentication token past the default 20 minutes
You can create a credential object using Get-Credential and entering the username and password at the prompts, or programmatically like this:
Thanks to Kotesh Bandhamravuri and his blog entry for this snippet.
There is a function called Test-Functionality that takes an F5Session object, a new pool name, a new virtual server, an IP address for the virtual server, and a computer name as a pool member, and validates nearly all the functions in the module.
I've also contributed this code sample for how to gather some basic info about your LTM with this PS module.
