iControl + Python + add_member / remove_member

Posted By mhite on 11/21/2012 11:14 AM

 

- Global variables, evil.

 

- remove_member is deprecated, use remove_member_v2 for V11 F5

 

- You pass global members into session_objects function parameter to delete_member... then you don't reference it. Why?

 

- You pass global 'members' to "remove_member" API call. It's the wrong type -- you are supposed to pass a sequence of IPPortDefinition.

 

 

I have a complete solution I've written for my current employer. Would love it if I could just post it but I don't have that freedom at this point. That being said, something like this works:

 

 

 def f5_build_address_port_seq(b, addressport): addressportseq = b.LocalLB.Pool.typefactory.create('Common.AddressPortSequence') addressportseq.item = addressport return addressportseq def f5_build_address_port(b, address, port): addressport = b.LocalLB.Pool.typefactory.create('Common.AddressPort') addressport.address = address addressport.port = port return addressport def f5_remove_pool_member_v11(b, poolname, address, port): addressport = f5_build_address_port(b, address, port) addressportseq = f5_build_address_port_seq(b, addressport) b.LocalLB.Pool.remove_member_v2(pool_names=[poolname], members=[addressportseq]) 

 

 

Then you just run:

 

 

f5_remove_pool_member_v11(b, poolname, address, port)

 

 

As an aside, if I were doing this from scratch, I'd be using bigsuds and not pycontrol.

 

mhite,

 

Thanks for your insights with the code snippets. I was able to patch/cobble together the rest of the script required to do the necessary operations for the moment.

 

As I learn python more in-depth, I'm sure that I'll be able to craft much better code than that currently hacked upon; I don't like using other people's code for the reason that it inhibits my own learning, but deadlines are deadlines and I needed to get something out quick and most of the framework was there with the base script linked to above... just needed to bolt a few extra things on 😃
