Abstract

The present technology addresses a need to automatically configure a new compute resource to join an existing cluster of computing resources. The present technology provides a mechanism to ensure that the new compute resource is executing the same kernel version which further permits subsequent exchange at least one configuration message informing the new compute resource of necessary configuration parameters and an address to retrieve required software packages.

First claim

The invention claimed is:

1. A computer-implemented method comprising:
receiving, at a computing cluster, a request to join the computing cluster from a computing resource;
transmitting, to the computing resource, a reply including information describing requirements to join the computing cluster and a reference to a software bundle used by members in the computing cluster;
authenticating the computing resource for membership to the computing cluster; and
accepting the computing resource in the computing cluster.

2. The computer-implemented method of claim 1 , wherein the request to join the computing cluster is a request to at least one member of the computing cluster for the information describing requirements to join the computing cluster.

3. The computer-implemented method of claim 1 , wherein the transmitting of the reply including the reference to the software bundle is a result of a determination made by at least one member of the computing cluster that the computing resource is not running a same version of the software bundle as the at least one member of the computing cluster.

4. The computer-implemented method of claim 1 , further comprising:
prior to the receiving of the request to join the computing cluster, receiving a preboot executing environment request; and
transmitting a boot image in response to the preboot execution environment request.

5. The computer-implemented method of claim 1 , wherein the information describing requirements to join the computing cluster includes membership authentication information.

6. The computer-implemented method of claim 1 , wherein the software bundle is contained in a Docker container that is executable by the computing resource.

7. The computer-implemented method of claim 1 , further comprising:
installing a software or configuration update by at least one member of the computing cluster; and
generating the software bundle containing the software or configuration included in the update and labeling the software bundle with a release version.

8. A system comprising:
at least one member of a computing cluster configured to:
receive a request to join the computing cluster from a computing resource;
transmit, to the computing resource, a reply including information describing requirements to join the computing cluster and a reference to a software bundle used by the at least one member in the computing cluster;
authenticate the computing resource for membership to the computing cluster; and
accept the computing resource in the computing cluster.

9. The system of claim 8 , wherein the request to join the computing cluster is a request to the at least one member of the computing cluster for the information describing requirements to join the computing cluster.

10. The system of claim 8 , wherein the transmission of the reply including the reference to the software bundle is a result of a determination made by the at least one member of the computing cluster that the computing resource is not running a same version of the software bundle as the at least one member of the computing cluster.

11. The system of claim 8 , wherein prior to receiving the request to join the computing cluster, the at least one member is configured to:
receive a preboot executing environment request; and
transmit a boot image in response to the preboot execution environment request.

12. The system of claim 8 , wherein the information describing requirements to join the computing cluster includes membership authentication information.

13. The system of claim 8 , wherein the software bundle is contained in a Docker container that is executable by the computing resource.

14. The system of claim 8 , wherein the at least one member is configured to:
install a software or configuration update; and
generate the software bundle containing the software or configuration included in the update and labeling the software bundle with a release version.

15. At least one non-transitory computer readable medium storing instructions, which when executed by at least one member of a computing cluster, the at least one member is configured to:
receive a request to join the computing cluster from a computing resource;
transmit, to the computing resource, a reply including information describing requirements to join the computing cluster and a reference to a software bundle used by the at least one member in the computing cluster;
authenticate the computing resource for membership to the computing cluster; and
accept the computing resource in the computing cluster.

16. The at least one non-transitory computer readable medium of claim 15 , wherein the request to join the computing cluster is a request to the at least one member of the computing cluster for the information describing requirements to join the computing cluster.

17. The at least one non-transitory computer readable medium of claim 15 , wherein the transmission of the reply including the reference to the software bundle is a result of a determination made by the at least one member of the computing cluster that the computing resource is not running a same version of the software bundle as the at least one member of the computing cluster.

18. The at least one non-transitory computer readable medium of claim 15 , wherein prior to receiving the request to join the computing cluster, the at least one member is configured to:
receive a preboot executing environment request; and
transmit a boot image in response to the preboot execution environment request.

19. The at least one non-transitory computer readable medium of claim 15 , wherein the software bundle is contained in a Docker container that is executable by the computing resource.

20. The at least one non-transitory computer readable medium of claim 15 , wherein the at least one member is configured to:
install a software or configuration update; and
generate the software bundle containing the software or configuration included in the update and labeling the software bundle with a release version.
