Hi everybody, We are implementing a Scheduler for Mesos in python, and we need to attach a preconfigured shared volume to a new Task. The Shared volume is now offered by the agents, we can get all information from the offer, but we do not know how to attach this volume to a new created task.
We are trying with the follow code:
for off_volume in offers_disks :
volume = task.resources.add()
volume.name = "disk"
volume.type = mesos_pb2.Value.SCALAR
volume.scalar.value = off_volume.scalar.value
volume.disk.persistence.id = off_volume.disk.persistence.id
volume.disk.volume.container_path =
off_volume.disk.volume.container_path
volume.disk.volume.mode = off_volume.disk.volume.mode
Where offer_disks are the list of offered shared volumes (as we said
previously, this volume was created before to try to launch the Tasks, with the
field “shared” defined); task is the new task created using
mesos_pb2.TaskInfo().
When we try to create this new task, the system says:
"Task uses invalid resources: Invalid DiskInfo: Persistent volumes cannot be
created from unreserved resources."
How can I attach this shared volume to my new Task?
Thanks in advance.
H.
