RackConnect and Managed Cloud
+++++++++++++++++++++++++++++
When using RackConnect version 2 or Rackspace Managed Cloud there are Rackspace automation tasks that are executed on the servers you create after they are successfully built. If your automation executes before the RackConnect or Managed Cloud automation, you can cause failures and un-usable servers.
These examples show creating servers, and ensuring that the Rackspace automation has completed before Ansible continues onwards.
For simplicity, these examples are joined, however both are only needed when using RackConnect. When only using Managed Cloud, the RackConnect portion can be ignored.
The RackConnect portions only apply to RackConnect version 2.
