Create Lifecycle Profile

Create a Lifecycle Profile for a standard Linux build:

  • Default profiles are selected for SovLabs IPAM and Naming modules
  • The custom script created above is selected to run in Machine Provisioned PRE
  • Default priorities are kept for EBS’, which means that SovLabs modules will run in their default priority in all phases of the VM lifecycle
Field Value
General tab Provide a Configuration label.
Select the appropriate SovLabs vRA CAFE Endpoint.
Leave Ignore SovLabs..? unchecked
Modules and Scripts tab - SovLabs Modules Select the desired IPAM profile from the IPAM dropdown
Select the desired Naming Standard from the Naming dropdown
Modules and Scripts tab - Machine Provisioned PRE Scripts Select the script created in the step above
Machine Building PRE tab Keep defaults
Machine Provisioned PRE tab Keep defaults
Machine Disposing PRE tab Keep defaults

Advanced tab Check the Generate JSON checkbox.

The Lifecycle Component JSON does not need to be edited in simple cases like this one. If there are multiple scripts that need to be in a particular order, then it might be necessary to modify the JSON directly. However, a script’s order can be defined on the Script Definition itself.
