Method and system for cross cluster container-based application cloning
Described are system and methods that provide for backing up a source cluster of a container-based application to a target cluster, using an intermediate store accessible by the source cluster and target cluster. The target cluster is registered and the container-based application is identified. Configuration and data of the container-based application is collected and written to intermediate store. A command identifying the target cluster to the intermediate store, which is read. If the identifier in the command and the identifier for the target are the same, a restore is performed to the target cluster.
1. A computer-implementable method for backing up a source cluster of a container-based application to a target cluster using an intermediate store comprising:
registering the target cluster;
identifying the container-based application;
collecting configuration and data of the container-based application;
writing the configuration and data of the container-based application to the intermediate store;
writing a command identifying the target cluster to the intermediate store;
reading the command identifying the target cluster from the intermediate store; and
performing a restore to the target cluster of the container-based application if the command identifying the target cluster matches identifier of the target cluster.
2. The computer-implementable method of claim 1 , wherein the source cluster and target are at different networks or sites.
3. The computer-implementable method of claim 1 , wherein the source cluster writes to the intermediate store and the target cluster reads from the intermediate store.
4. The computer-implementable method of claim 1 , wherein the identifying the container-based application is by namespace or label.
5. The computer-implementable method of claim 1 , wherein the configuration includes namespaces, deployments, services, pods, persistent volume claims and other resources.
6. The computer-implementable method of claim 1 , wherein the writing the command further comprises writing which back up to use for restore.
7. The computer-implementable method of claim 1 further comprising providing status or results of the restore to the intermediate store.
8. A system comprising:
a plurality of processing systems communicably coupled through a network, wherein the processing systems include non-transitory, computer-readable storage medium embodying computer program code interacting with a plurality of computer operations for backing up a source cluster of a container-based application to a target cluster using an intermediate store comprising:
registering the target cluster;
identifying the container-based application;
collecting configuration and data of the container-based application;
writing the configuration and data of the container-based application to the intermediate store;
writing a command identifying the target cluster to the intermediate store;
reading the command identifying the target cluster from the intermediate store; and
performing a restore to the target cluster of the container-based application if the command identifying the target cluster matches identifier of the target cluster.
9. The system of claim 8 , wherein the source cluster and target are at different networks or sites.
10. The system of claim 8 , wherein the source cluster writes to the intermediate store and the target cluster reads from the intermediate store.
11. The system of claim 8 , wherein the identifying the container-based application is by namespace or label.
12. The system of claim 8 , wherein the configuration includes namespaces, deployments, services, pods, persistent volume claims and other resources.
13. The system of claim 8 , wherein the writing the command further comprises writing which back up to use for restore.
14. The system of claim 8 further comprising providing status or results of the restore to the intermediate store.
15. A non-transitory, computer-readable storage medium embodying computer program code for backing up a source cluster of a container-based application to a target cluster using an intermediate store, the computer program code comprising computer executable instructions configured for:
registering the target cluster;
identifying the container-based application;
collecting configuration and data of the container-based application;
writing the configuration and data of the container-based application to the intermediate store;
writing a command identifying the target cluster to the intermediate store;
reading the command identifying the target cluster from the intermediate store; and
performing a restore to the target cluster of the container-based application if the command identifying the target cluster matches identifier of the target cluster.
16. The non-transitory, computer-readable storage medium of claim 15 , wherein the source cluster and target are at different networks or sites.
17. The non-transitory, computer-readable storage medium of claim 15 , wherein the source cluster writes to the intermediate store and the target cluster reads from the intermediate store.
18. The non-transitory, computer-readable storage medium of claim 15 , wherein the identifying the container-based application is by namespace or label.
19. The non-transitory, computer-readable storage medium of claim 15 , wherein the configuration includes namespaces, deployments, services, pods, persistent volume claims and other resources.
20. The non-transitory, computer-readable storage medium of claim 15 , further comprising providing status or results of the restore to the intermediate store.
