Detecting and tracking virtual containers
Examples of techniques for detecting and tracking virtual containers are disclosed. In one example implementation according to aspects of the present disclosure, a computer-implemented method includes detecting a virtual container. The method further includes collecting virtual container data for the virtual container. The method also includes associating, by a processing device, the virtual container to at least one of a plurality of images. Additionally, the method includes building, by the processing device, a container event database based on the virtual container data and the association of the virtual container to the at least one of the plurality of images, so as to enable tracking of software in the plurality of images and in live virtual containers.

12. The computer-implemented method of claim 11 , comprising:
determining, via the processing device, whether the license quantity limit stored in a software license database is exceeded based on the virtual container record; and
reporting, via the processing device, a licensing violation when it is determined that the license quantity limit is exceeded.
13. The computer-implemented method of claim 11 , comprising, in response to the set of images associated with the virtual container being determined to be unknown, looking up the set of images, via the processing device, in a container event database.
14. The computer-implemented method of claim 13 , wherein looking up the set of images comprises submitting, via the processing device, an image history of the set of images to a submission queue, wherein the image history corresponds to a portion of a hierarchical tree associated with the set of images.
15. The computer-implemented method of claim 11 , comprising detecting, via the processing device, the event associated with the virtual container by monitoring a container engine of a host computing device.
16. A non-transitory computer-readable medium comprising computer-readable code, that when executed by one or more processors, causes the one or more processors to perform operations comprising:
determining whether an event associated with a virtual container of a plurality of virtual containers is a create event indicative of a creation of the virtual container or a destroy event indicative of a removal of the virtual container, wherein the virtual container of the plurality of virtual containers is configured to run a set of images corresponding to a licensed software application;
in response to the event being determined to be the create event, determining whether the set of images associated with the virtual container are known; and
in response to the set of images associated with the virtual container being determined to be known, creating a virtual container record comprising an image ID, a container ID, an indication of an action associated with the event, an indication of a time the action occurred, an indication of a mapped component associated with the licensed software application, or a license quantity limit associated with the licensed software application, or any combination thereof.
