Adding a iRule to a Virtual Server

The add_rule() method expects to have a keyword argument called 'rules' - Suds does a decent job of figuring out unambiguous keyword arguments, but for anything with embedded objects it'll have problems.

http://devcentral.f5.com/wiki/default.aspx/iControl/LocalLB__VirtualServer__add_rule.html

So try something like:

c.add_rule(['VIP'], rules = convert_rule(b, 'iRule'))

Hth,

Hello,

 

 

I tried to use this code on my 10.2.3 LTM without success. I get either a similar error as the above user or no error at all and the irule is not applied.

 

 

My goal is to remove one irule and add another to many Virtual Servers at once.

 

 

Is there an example out there?

 

 

Thanks,

Hi Jomar,

unfortunately I couldn't figure it out as well with pyControl2 yet.

Here is a solution based on SOAPpy:

 
!/usr/bin/env python

import SOAPpy
import sys
from optparse import OptionParser
 
def f5Conn(options):
    iControlUrl = "https://%s:%s@%s/iControl/iControlPortal.cgi" %(options.bigipUsername,options.bigipPassword,options.bigipHost)
    iControlVirtualServerNamespace = "urn:iControl:LocalLB/VirtualServer"
    vsProxy = SOAPpy.SOAPProxy(iControlUrl, iControlVirtualServerNamespace)
    return vsProxy
 
def addRuleToVirtualServer(vsProxy, rule, priority, vs):
    ruleStructure = dict(rule_name=rule, priority=priority)
    for item in vs:
        try:
            res = vsProxy.add_rule(
                virtual_servers=[item],
                rules = [[ruleStructure]]
            )
        except:
           return sys.exc_info()[1]
 
def removeRuleFromVirtualServer(vsProxy, delRule, ruleList):
    for ruleListItem in ruleList:
        for (vserver,rules) in ruleListItem:
            for (a,b) in rules:
                    if (delRule in a):
                        ruleStructure = dict(rule_name=a, priority=b)
                        try:
                            res = vsProxy.remove_rule(
                                virtual_servers=[vserver],
                                rules = [[ruleStructure]]
                            )
                        except:
                            return sys.exc_info()[1]
 
if __name__ == '__main__':
    foo

Guys I will pull together an example of how to do this. It'll be Wednesday before I can get to it though...

Hi again,

thanks to Matt's hint I figured it out - it's a serialization issue:

Your convert_rule() should look like this:

ruleSequence = bigip.LocalLB.VirtualServer.typefactory.create('LocalLB.VirtualServer.VirtualServerRuleSequence')

ruleSet = bigip.LocalLB.VirtualServer.typefactory.create('LocalLB.VirtualServer.VirtualServerRule')

ruleSet.rule_name = ruleName

ruleSet.priority = priority

ruleSequence.item = [ruleSet]

return [ruleSequence]

And then execute it like:

bigip.LocalLB.VirtualServer.add_rule(virtual_servers = ['/Common/VS'], rules = [convert_rule(bigip, '/Common/test', '')])
