Updating "Default Pool" via Portal

There's no functionality to limit what is displayed on a configuration screen, or to project some of that configuration into another environment. You could technically attempt to expose the BIG-IP management GUI through an APM portal, technically possible but not trivial. But your best bet probably, given that you want to expose a very limited setting, is to roll your own iControl. Thankfully the new iControl REST interface makes that exceedingly easier.

Hi!

You could achieve this with iControl, but the catch is that you'd need to save the username and password in a file. Do you have any experience in scripting?

Also you might be able to do it with iStats and iRules. Jason Rahm wrote an excellent article on how to use iStats to execute tmsh commands:

Then use this command:

modify ltm virtual [virtual server name] pool [pool name]

Instead of:

tmsh::modify wam application dc.wa_hero content-expiration-time now    

You'd have to change the iRule too. Maybe something like this?

when HTTP_REQUEST {
  if { [HTTP::path] eq "/setdefaultpool" } {
    set defpool [URI::query [HTTP::uri] defpool]
    if { [class match $defpool equals allowedpools] } {
      ISTATS::set "WA policy string [virtual name]$defpool" 1
      HTTP::respond 200 content "Set $defpool as default pool on [virtual name]."
    } else { HTTP::respond 200 content "Please specify a valid pool /setdefaultpool?defpool=pool_name" }
  }
}

Note that this is a bit messy and requires quite alot of config. I have not tested this but it should be possible.

Hopefully Kevin Stewart or Nitas comes up with something brilliant alternative!

These are interesting techniques Patrik. I think the absolute simplest approach though is still an iControl. I'm not going to venture too far down the "which language is better for this" sort of thing, because it depends on what you're comfortable with. But if I was doing this, and I wanted to do it quickly, I'd probably build a Perl or Python script, or PHP-based webpage on some web server and use iControl REST. That would be very easy to incorporate into some third party portal product.

check iControl, it will help achieving your goal

Hi All

Which version of Visual Studio should I be using?

Which version of Visual Studio should I be using?

I'm not sure that it matters, or at least it's not mentioned in the .NET iControl library download:

I'd imagine you could probably go a few versions back from the latest.
