Cloud Foundry Tracker implements the JobTracker interface used by the Go DRMAA2 implementation in order to use Cloud Foundry tasks as a backend for managing jobs as containers using the DRMAA2 interface.
A JobTemplate requires at least:
- JobCategory -> which maps to a pushed application GUID
- RemoteCommand -> which is path to an executable in the container image of the application
| DRMAA2 Job Control | Cloud Foundry |
|---|---|
| Suspend | Unsupported |
| Resume | Unsupported |
| Terminate | Terminate Task |
| Hold | Unsupported |
| Release | Unsupported |
| DRMAA2 State | Cloud Foundry State |
|---|---|
| Queued | PENDING |
| Running | CANCELING |
| Running | RUNNING |
| Done | SUCCEEDED |
| Failed | FAILED |
Delete job (purging the task information in Cloud Foundry) is not implemented.
Following mapping between the job template and the Cloud Foundry task request is done:
| DRMAA2 JobTemplate | Cloud Foundry Task Request |
|---|---|
| RemoteCommand | Command |
| JobName | Name |
| MinPhysMemory (in byte) | MemoryInMegabyte |
| Args | are added to Command |
| JobCategory | DropletGUID |
| WorkingDir |
