Cloud Foundry Tracker

Introduction

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.

Functionality

Basic Usage

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

Job Control Mapping

DRMAA2 Job Control	Cloud Foundry
Suspend	Unsupported
Resume	Unsupported
Terminate	Terminate Task
Hold	Unsupported
Release	Unsupported

State Mapping

DRMAA2 State	Cloud Foundry State
Queued	PENDING
Running	CANCELING
Running	RUNNING
Done	SUCCEEDED
Failed	FAILED

DeleteJob

Delete job (purging the task information in Cloud Foundry) is not implemented.

Job Template Mapping

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
