Abstract

A computer-implemented method, computer program product, and/or computing system for preforming at least one of a performance group consisting of undoing an action in and uninstalling a software application from a computing environment. The computer-implemented method, computer program product, and/or computing system includes: building an initial resource dependency graph; building a second resource dependency graph; determining a resulting resource dependency graph to identify dangling resources; and removing the dangling resources. In an embodiment, building at least one of the initial resource dependency graph or the second resource dependency graph includes building a resource ownership graph and extending the resource ownership graph to include associations to form a resource dependency graph

Dependent claims

A computer implemented method for performing at least one of a performance group consisting of undoing an action in and uninstalling a software application from a computing environment, the method comprising:

building an initial resource dependency graph for the computing environment, wherein the initial resource dependency graph identifies resources owned and associated with at least one of an action group consisting of the action and the software application before performing the performance group;
building a second resource dependency graph for the computing environment, wherein the second resource dependency graph identifies resources owned and associated with the action group after performing the performance group;
determining a resulting resource dependency graph to identify dangling resources in the computing environment after performing the performance group, wherein the resulting resource dependency graph is a difference in the identified resources between the initial resource dependency graph and the second resource dependency graph;
and
removing the dangling resources from the computing environment.

2 more elements

A computer-implemented method of uninstalling a software application, the method comprising:

forming an initial resource dependency graph before uninstalling the software application, wherein the initial resource dependency graph identifies resources in the computing environment owned and associated with the software application and comprises one or more nodes where each node identifies one of the resources and the initial resource dependency graph identifies resource dependencies;
forming a second resource dependency graph after uninstalling the software application, wherein the second resource dependency graph identifies resources in the computing environment owned and associated with the software application comprising one or more nodes where each node identifies one of the resources and the second resource dependency graph identifies resource dependencies;
form a resulting resource dependency graph by comparing the one or more nodes within the initial resource dependency graph to the one or more nodes within the second resource dependency graph to identify dangling resources;
and
remove the dangling resources,
wherein forming the initial resource dependency graph or the second resource dependency graph comprises:
forming an initial resource ownership graph and a second resource ownership graph by:
scanning a target system in the computing environment for resource manifests stored in a resource datastore;
determining existing ownerReference definitions among resources for explicit dependencies;
parsing resource explicit dependencies;
and
forming the initial resource ownership graph and the second resource ownership graph;
and
extending the initial resource ownership graph and the second resource ownership graph to include associations to form the initial resource dependency graph and the second resource dependency graph by:
scanning container logs to identify associations among resources for implicit dependencies;
tracking service to service communications to identify associations among resources for implicit dependencies;
and
extending the initial resource ownership graph and the second resource ownership graph to include the respective identified associations.
