Update the condition of a load balancer node with libcloud

update-lb.py

import os
import time

from libcloud.loadbalancer.types import State, Provider, MemberCondition
from libcloud.loadbalancer.providers import get_driver

username = os.environ['RACKSPACE_USERNAME']
apikey = os.environ['RACKSPACE_APIKEY']
region = os.environ['RACKSPACE_REGION']

# Find the load balancer.
lb = None
lbs = driver.list_balancers()
for each in lbs:
    if each.name == clb_name:
        lb = each

if not lb:
    raise RuntimeError("Unable to find the load balancer")

print "Updating load balancer:", lb.name

# Find the member we want to update.
member = None
members = lb.list_members()
for each in members:
    if each.ip == server_addr and each.port == server_port:
        member = each

if not member:
    raise RuntimeError("Unable to find the member to update")

print "Updating member:", member.ip

driver.ex_balancer_update_member(lb, member,
                                 condition=MemberCondition.DRAINING)

while True:
    balancer = driver.get_balancer(balancer_id=lb.id)
    if balancer.state == State.RUNNING:
        break

    time.sleep(5)

print "Member is now draining connections."

Documentation for the Rackspace load balancer driver, including Rackspace-specific extension methods like ex_balancer_update_member.

Thanks for your solution.
Do you know if it's possible to get the member condition too.
