ray.runtime_context.get_runtime_context

ray.runtime_context.get_runtime_context() → RuntimeContext

Get the runtime context of the current driver/worker.

The obtained runtime context can be used to get the metadata of the current task and actor.

Note: For Ray Client, ray.get_runtime_context().get_node_id() should point to the head node. Also, keep in mind that ray._private.worker.global_worker will create a new worker object here if global_worker doesn’t point to one.

Example

import ray
# Get the job id.
ray.get_runtime_context().get_job_id()
# Get the actor id.
ray.get_runtime_context().get_actor_id()
# Get the task id.
ray.get_runtime_context().get_task_id()
