Delete resources

This guide describes how to delete App Lifecycle Manager resources. App Lifecycle Manager ensures data integrity by blocking resource deletions when dependent resources exist.

A dependent resource has a reference to the resource you want to delete. For example, a unit is dependent on a unit kind. You cannot delete a unit kind if a unit references it.

App Lifecycle Manager resource dependency

This table describes the dependency relationships between App Lifecycle Manager resources. The resource in the header column can only be deleted if there are no resources from the header row that reference that resource instance. For example, a unit kind resource cannot be deleted if a unit or release is referencing the unit kind.

Resource type	Unit kind	Unit	Unit operation	Release	Rollout	Tenant
Unit Kind		X		X
Unit	X	X		X		X
Unit Operation		X			X
Release	X	X
Rollout Kind					X
Rollout			X
