Abstract

Systems, methods, and other embodiments associated with automated upgrade of an operating system are described. In one embodiment, a method includes receiving a request for an upgrade package in a gateway server from a remote device and determining a source location for the upgrade package. The example method may also include sending the request to the source location to cause the source location to provide the upgrade package to the remote device.

Claims

1. A non-transitory computer-readable medium storing computer-executable instructions that when executed by a computer cause the computer to perform a method, the method comprising:

receiving, in a gateway server in response to a remote device initiating an operating system (OS) upgrade from a configuration file, a request for an upgrade package;

resolving a source location for the upgrade package based, at least in part, on metadata in the request, wherein the metadata is from the configuration file; and

sending the request over a network to the resolved source location for the upgrade package to cause an upgrade server associated with the resolved source location to send the upgrade package to the remote device.

2. The non-transitory computer-readable medium of claim 1, wherein the configuration file is an RPM package manager (RPM) configuration file that identifies at least the upgrade package, and wherein the operating system is an open source operating system.

3. The non-transitory computer-readable medium of claim 1, wherein the gateway server receives the request in response to the remote device initiating a package management system using the configuration file.

4. The non-transitory computer-readable medium of claim 1, further comprising resolving the source location for the upgrade package by:

determining one or more available source locations for the upgrade package from a plurality of source locations in a lookup table based, at least in part, on attributes of the plurality of source locations; and

selecting a source location from the one or more available source locations based, at least in part, on one or more attributes of the remote device.

5. The non-transitory computer-readable medium of claim 4, wherein the one or more attributes of the remote device include a list of previously installed upgrades on the remote device for the operating system.

6. The non-transitory computer-readable medium of claim 1, wherein the gateway server intercepts the request on the network before the request arrives at an original destination identified in the request.

7. The non-transitory computer-readable medium of claim 1, wherein the gateway server is a router, and wherein sending the request to the resolved source location includes redirecting the request from an original destination to the resolved source location.

20. The non-transitory computer-readable medium of claim 1, wherein the gateway server is a router, and wherein sending the request to the resolved source location includes redirecting the request from an original destination to the resolved source location.

8. An upgrade controller, comprising:

upgrade logic configured to;

receive, in response to a remote device initiating an operating system (OS) upgrade from a configuration file, a request for an upgrade package;

resolve a source location for the upgrade package by performing a lookup in a lookup table based, at least in part, on metadata in the request, wherein the metadata is from the configuration file and the source location is in a network associated with the update controller; and

send the request over a network to the resolved source location for the upgrade package to cause an upgrade server associated with the resolved source location to send the upgrade package to the remote device.

9. The upgrade controller of claim 8, wherein the configuration file is an RPM package manager (RPM) configuration file that identifies at least the upgrade package, and wherein the operating system is an open source operating system.

10. The upgrade controller of claim 8, wherein the upgrade logic is configured to receive the request in response to the remote device initiating a package management system using the configuration file.

11. The upgrade controller of claim 8, wherein the upgrade logic is further configured to resolve the source location for the upgrade package by:

determining one or more available source locations for the upgrade package from a plurality of source locations in the lookup table based, at least in part, on attributes of the plurality of source locations, and

selecting a source location from the one or more available source locations based, at least in part, on one or more attributes of the remote device.

12. The upgrade controller of claim 8, wherein the one or more attributes of the remote device include a list of previously installed upgrades on the remote device for the operating system.

13. The upgrade controller of claim 8, wherein the upgrade controller is embodied in a gateway server, wherein the upgrade logic is configured to intercept the request on the network before the request arrives at an original destination identified in the request.

14. The upgrade controller of claim 8, wherein the upgrade controller is embodied in a router, and wherein the upgrade logic is configured to send the request to the resolved source location by redirecting the request from an original destination to the resolved source location.

15. A non-transitory computer-readable medium storing computer-executable instructions that when executed by a computer cause the computer to perform a method, the method comprising:

intercepting, in a gateway server in response to a remote device initiating a configuration file, a request for an upgrade package;

resolving a source location for the upgrade package from a lookup table based, at least in part, on metadata in the request; and

re-directing the request over a network to the source location resolved from the lookup table to cause an upgrade server associated with the source location to send the upgrade package to the remote device.

16. The non-transitory computer-readable medium of claim 15, wherein the configuration file is an RPM package manager (RPM) configuration file that identifies at least the upgrade package for an operating system (OS) of the remote device, wherein the metadata is from the configuration file, and wherein the operating system is an open source OS.

17. The non-transitory computer-readable medium of claim 15, wherein the gateway server receives the request in response to the remote device initiating a package management system using the configuration file.

18. The non-transitory computer-readable medium of claim 15, further comprising resolving the source location for the upgrade package by:

determining one or more available source locations for the upgrade package from a plurality of source locations in a lookup table; and

selecting a source location from the one or more available source locations based, at least in part, on one or more attributes of the remote device.

19. The non-transitory computer-readable medium of claim 18, wherein the one or more attributes of the remote device include a list of previously installed upgrades on the remote device for an operating system of the remote device.
