Chapter 10. Update Load Balancer Attributes

Assume that you want to change the algorithm for your load balancer from RANDOM to LEAST_CONNECTIONS. You can use the Update Load Balancer Attributes API call to accomplish this task. This call allows you to change one or more of the following load balancer attributes:

The following examples show the cURL requests for Update Load Balancer Attributes to change the algorithm to LEAST_CONNECTIONS:

curl -i -d \
'<?xml version="1.0" ?>
<loadBalancer xmlns="http://docs.openstack.org/loadbalancers/api/v1.0"
    algorithm="LEAST_CONNECTIONS" />' \
-H 'X-Auth-Token: your_auth_token' \
-H 'Content-Type: application/xml' \
-H 'Accept: application/xml' \
-X PUT \
'https://dfw.loadbalancers.api.rackspacecloud.com/v1.0/your_acct_id/loadbalancers/load_balancer_id'

curl -i -d \
'{"loadBalancer":{
    "algorithm": "LEAST_CONNECTIONS"
    }
}' \
-H 'X-Auth-Token: your_auth_token' \
-H 'Content-Type: application/json' \
-X PUT \
'https://dfw.loadbalancers.api.rackspacecloud.com/v1.0/your_acct_id/loadbalancers/load_balancer_id'

This operation does not return a response body.

You can now confirm that the algorithm is changed by calling List Load Balancer Details, as described in Chapter 8, List Load Balancer Details.

You can also view the information for the load balancer you have created by clicking Load Balancers in the Hosting section of the Control Panel. Then click the name of the load balancer to view the details.

This concludes the Getting Started. Thank you for using Rackspace Cloud products.
