Abstract

Embodiments relate to systems and methods for generating cached representations of host package inventories in remote package repositories. A physical or virtual client machine can host a set of installed software packages, including operating system, application, and/or other software. A package manager installed on the client reports an inventory of the installed packages to one or more package servers. The package server(s) can receive the inventory from machines populating the managed network, and generate an encoded identification for each constituent package, such as a hash-based output based on package attributes. The encoded identification and other data can be stored to an aggregate package cache in the one or more package servers, for more efficient management of the host machines in the managed network. In embodiments, the package update files for each identifier can also be stored in the cache for even more efficient inventorying and package update operations.

Claims

1. A method, comprising:

receiving an inventory of installed packages of a plurality of host machines;

generating an aggregate inventory of installed packages on the plurality of host machines;

encoding an identifier for each package in the aggregate inventory of installed packages, wherein the aggregate inventory comprises the identifier for each package in the aggregate inventory;

storing, by a remote package platform, the aggregate inventory of installed packages in an aggregate package cache associated with a remote package platform; and

accessing, by a remote package platform, the aggregate package cache in response to a package update request.

2. The method of claim 1, wherein the encoded identifiers comprise identifiers produced by applying a hash function to a set of attributes of the aggregate inventory.

3. The method of claim 2, wherein the set of attributes comprises at least one of a package name identifier, a package version identifier, a package epoch identifier, a package timestamp identifier, a package size identifier, a file name identifier, a file version identifier, a file timestamp identifier, or a file size identifier.

4. The method of claim 1, wherein the aggregate inventory comprises at least one of an inventory of a set of installed packages or an inventory of a set of component files associated with the installed packages.

5. The method of claim 1, further comprising initiating a package update to one of the plurality of host machines.

6. The method of claim 5, further comprising generating an update to the aggregate package cache after the package update is installed in a host machine.

7. The method of claim 5, wherein the initiating a package update comprises initiating a package update to the plurality of host machines via the aggregate package cache on a collective basis.

8. The method of claim 1, wherein the plurality of host machines comprise a set of virtual machines.

9. The method of claim 8, wherein the set of virtual machines is hosted in a cloud-based network.

10. The method of claim 1, wherein the plurality of host machines comprise a set of hardware-based machines.

11. The method of claim 1, wherein the remote package platform comprises at least one of a package server or a package repository.

12. The method of claim 1, further comprising storing at least one package update in the aggregate package cache in association with at least one of the encoded identifiers.

13. The method of claim 1, further comprising storing a plurality of package updates in the aggregate package cache in association with a plurality of encoded identifiers.

14. The method of claim 1, wherein the accessing, by the remote package platform, the aggregate package cache comprises responding to the package update request using an encoded identifier.

15. The method of claim 14, further comprising generating an update to the aggregate package cache after the package update is installed in a host machine and wherein the update to the aggregate package cache comprises an update to the encoded identifiers stored in the aggregate package cache based on attributes of the package update.

16. A package management system, comprising:

a network interface to a plurality of host machines;

an aggregate package cache; and

a processor, communicating with the plurality of host machines via the network interface and with an aggregate package cache, the processor to

receive an inventory of installed packages of each host machine in a managed network;

generate an aggregate inventory of installed packages on the plurality of host machines the managed network;

encode an identifier for each package in the aggregate inventory of installed packages;

store the aggregate inventory of installed packages to the aggregate package cache; and

access the aggregate package cache in response to a package update request.

17. The system of claim 16, wherein the processor to initiate a package update to a host machine.

18. The system of claim 16, wherein the processor to store at least one package update in the aggregate package cache in association with the encoded identifier.

19. The system of claim 17, wherein the package management system further comprises a package repository, wherein the package update is stored in the package repository.

20. The system of claim 19, wherein the processor is in a package server and the package update is stored in the package repository.
