The first cloud environment configured in NSX Advanced Load Balancer is named Default-Cloud. This section describes how to correctly remove and reset the configured default cloud, Default-Cloud, from NSX Advanced Load Balancer, when the default cloud is OpenStack.
Reset Default Cloud
When creating a new cloud connector in NSX Advanced Load Balancer, other objects are created to support the configuration, both on the NSX Advanced Load Balancer Controller and in the target cloud environment (OpenStack, VMware vCenter, AWS, and so on).
For a non-default cloud, you can delete entire cloud, once it is no longer in use. This delete action triggers a cleanup of related objects in the cloud environment. For instance, deleting a custom OpenStack cloud connector deletes all Service Engines, Neutron security groups, Nova anti-affinity groups, Neutron ports, and glance images in OpenStack that were created as part of NSX Advanced Load Balancer installation and operation.
Since the NSX Advanced Load Balancer default cloud cannot be deleted, this creates challenges for cleaning up OpenStack objects when removing NSX Advanced Load Balancer from OpenStack. Though the configuration can be converted to no access mode, this leaves all objects in the cloud intact for manual control.
Steps for Resetting the Default Cloud
To remove the OpenStack cloud connector for the default cloud, use the following steps.
Delete all virtual services and pools from the cloud. The cloud cannot be deleted if it still contains any of these resources.
Connect to the NSX Advanced Load Balancer Controller through SSH or the console.
Connect to the CLI shell.
Run
exec cloud Default-Cloud gc force cleanupcommand.Exit the shell.
