Abstract

A system and a method are disclosed to configure networking components, including in response to a first configuration command, creating a running configuration for a host computer, saving the running configuration in a configuration file stored in a temporary directory, and in response to receiving a second configuration command to make the running configuration persistent, copying the configuration file to a persistent directory.

Claims

1. A method comprising:

in response to a first configuration command, creating a running configuration for a host computer;

saving the running configuration in a plurality of configuration files stored in a temporary directory;

in response to receiving a second configuration command to make the running configuration persistent, copying the plurality of configuration files to a persistent directory.

2. The method of claim 1, further comprising:

in response to a reboot of the host computer, executing a third configuration command to set up a network configuration of the host computer using the plurality of configuration files stored in the at least one persistent directory.

3. The method of claim 1, further comprising:

receiving a fourth configuration command to set up network configurations for the host computer;

executing the fourth configuration command to create a second running configuration for the host computer; and

saving the second running configuration in a second plurality of configuration files stored in the temporary directory.

4. The method of claim 3, further comprising:

reverting the second running configuration back to the running configuration using configuration files stored in the temporary directory.

5. The method of claim 1, wherein the plurality of configuration files of the running configuration comprise an address and an identifier of a networking component of the host computer.

6. The method of claim 1 further comprises:

building the running configuration in a memory of the host computer from configuration files stored in the temporary directory and data indicating networking changes received in the first configuration command; and

saving the plurality of configuration files of the built running configuration in the temporary directory.

7. The method of claim 1, wherein the copy operation is an atomic operation with respect to the plurality of configuration files.

8. An apparatus comprising:

a storage device; and

a processing device communicably coupled to the storage device and to;

in response to a first configuration command, create a running configuration for the processing device;

save the running configuration in a plurality of configuration files stored in a temporary directory; and

in response to receiving a second configuration command to make the running configuration persistent, copy the plurality of configuration files to a persistent directory.

9. The apparatus of claim 8, wherein the processing device is further to:

in response to a reboot of the processing device, execute a third configuration command to set up a network configuration of the processing device using the plurality of configuration files stored in the at least one persistent directory.

10. The apparatus of claim 8, wherein the processing device is further to:

receive a fourth configuration command to set up network configurations for the processing device;

execute the fourth configuration command to create a second running configuration for the processing device; and

save the second running configuration in a second plurality of configuration files stored in the temporary directory.

11. The apparatus of claim 10, wherein the processing device is further to:

revert the second running configuration back to the running configuration using configuration files stored in the temporary directory.

12. The apparatus of claim 8, wherein the plurality of configuration files of the running configuration comprise an address and an identifier of a networking component of the processing device.

13. The apparatus of claim 8, further comprising:

building the running configuration in a memory of the processing device from configuration files stored in the temporary directory and data indicating networking changes received in the first configuration command; and

saving the plurality of configuration files of the built running configuration in the temporary directory.

14. The apparatus of claim 8, wherein the copy operation is an atomic operation with respect to the plurality of configuration files.

15. A non-transitory computer readable storage medium comprising instructions that, when executed by a host computer, cause the host computer to perform operations comprising:

in response to a first configuration command, creating a running configuration for the host computer;

saving the running configuration in a plurality of configuration files stored in a temporary directory; and

in response to receiving a second configuration command to make the running configuration persistent, copying the plurality of configuration files to a persistent directory.

16. The non-transitory computer readable storage medium of claim 15, wherein the operations further comprises:

in response to a reboot of the host computer, executing a third configuration command to set up a network configuration of the host computer using plurality of configuration files stored in the at least one persistent directory.

17. The non-transitory computer readable storage medium of claim 15, wherein the operations further comprises:

receiving a fourth configuration command to set up network configurations for the host computer;

executing the fourth configuration command to create a second running configuration for the host computer; and

saving the second running configuration in a second plurality of configuration files stored in the temporary directory.

18. The non-transitory computer readable storage medium of claim 15, wherein the plurality of configuration files of the running configuration comprise an address and an identifier of a networking component of the host computer.

19. The non-transitory computer readable storage medium of claim 15, wherein the operations further comprise:

building the running configuration in a memory of the host computer from configuration files stored in the temporary directory and data indicating networking changes received in the first configuration command; and

saving the plurality of configuration files of the built running configuration in the temporary directory.

20. The non-transitory computer readable storage medium of claim 15, wherein the copy operation is an atomic operation with respect to the plurality of configuration files.
