Usage
Not much documentation at the moment but just some quick typical usage
scripts you can do with this library. This is based on the latest version from :
http://docs.rackspacecloud.com/loadbalancers/api/clb-devguide-latest.pdf
Create a LoadBalancer:
#!/usr/bin/python
import cloudlb
clb = cloudlb.CloudLoadBalancer("username", "apikey","chicago")
node1 = cloudlb.Node(address="10.180.160.131",
port=80,
condition="ENABLED")
virtualIP1 = cloudlb.VirtualIP(
type="PUBLIC")
clb.loadbalancers.create(name="mytestinglb",
port=80,
protocol="HTTP",
nodes=[node1],
virtualIps=[virtualIp1])
List LoadBalancers:
#!/usr/bin/python
import cloudlb
clb = cloudlb.CloudLoadBalancer("username", "apikey","chicago")
lbs = clb.loadbalancers.list()
for lb in lbs:
print "%s has %s node attached with IP addresses:" % (lb.name, len(lb.nodes))
for ip in lb.virtualIps:
print "%s/%s" % (ip.ipVersion, ip.address)
List LoadBalancers who have nodes that belong to it:
#!/usr/bin/python
import cloudlb
clb = cloudlb.CloudLoadBalancer("username", "apikey","chicago")
ip = '10.1.1.1'
lbs = clb.loadbalancers.search(ip)
for lb in lbs:
print "%s has %s node attached" % (lb.name, ip))
Get LB by ID:
#!/usr/bin/python
import cloudlb
clb = cloudlb.CloudLoadBalancer("username", "apikey","chicago")
clb.authenticate()
lb = clb.loadbalancers.get(LoadBalancerID)
Delete LB:
#!/usr/bin/python
import cloudlb
clb = cloudlb.CloudLoadBalancer("username", "apikey","chicago")
lb = clb.loadbalancers.get(LoadBalancerID)
lb.delete()
List nodes of a LB:
#!/usr/bin/python
import cloudlb
clb = cloudlb.CloudLoadBalancer("username", "apikey","chicago")
lbs = clb.loadbalancers.list()
lb = lbs[0] #get the first one
nodes=lb.nodes.filter(status='ENABLED')
for node in nodes:
print node.address
Filter nodes via condition of a LB:
#!/usr/bin/python
import cloudlb
clb = cloudlb.CloudLoadBalancer("username", "apikey","chicago")
lbs = clb.loadbalancers.list()
lb = lbs[0] #get the first one
for node in lb.nodes:
print node.address
Add a node to a LB:
#!/usr/bin/python
import cloudlb
clb = cloudlb.CloudLoadBalancer("username", "apikey","chicago")
newnode = cloudlb.Node(address="10.180.160.131",
port=80,
condition="ENABLED")
lbs = clb.loadbalancers.list()
lb = lbs[0] #add to the first one
lb.add_nodes([newnode])
Delete a node from a LB:
#!/usr/bin/python
import cloudlb
clb = cloudlb.CloudLoadBalancer("username", "apikey","chicago")
lbs = clb.loadbalancers.list()
lb = lbs[0] #add to the first one
node = lb.nodes[0] #get the first node
node.delete() #delete it
Update attributes of a node:
#!/usr/bin/python
import cloudlb
clb = cloudlb.CloudLoadBalancer("username", "apikey","chicago")
lbs = clb.loadbalancers.list()
mylb = lbs[0] #add to the first one
nodeid = 14106
nodes = mylb.nodes
node = mylb.nodes.get(nodeid)
toggle_status = node.condition == "ENABLED" and "DISABLED" or "ENABLED"
node.condition = toggle_status
node.update()
Get weight of a node by using .get():
#!/usr/bin/python
import cloudlb
clb = cloudlb.CloudLoadBalancer("username", "apikey","chicago")
lbs = clb.loadbalancers.list()
mylb = lbs[0] #add to the first one
nodeid = 14106
nodes = mylb.nodes
node = mylb.nodes.get(nodeid)
print node.weight
Update attributes on LoadBalancer:
#!/usr/bin/python

mylb = lbs[0] #first lb
mylb.protocol = "FTP"
mylb.name = "APrettyNewName"
mylb.update()

#!/usr/bin/python
import cloudlb
clb = cloudlb.CloudLoadBalancer("username", "apikey","chicago")
print clb.get_usage()
Get usage statistics on a specfic LoadBalancer:
#!/usr/bin/python
