description:
|
|
- Adds, modifies and removes nodes from a Rackspace Cloud Load Balancer.
|
|
- This module relies on the C(pyrax) package which is deprecated in favour of using Openstack API.
|
|
- Unless maintainers step up to work on the module, it will be marked as deprecated in community.general 7.0.0 and removed in version 9.0.0.
