flytekit.clients.friendly.SynchronousFlyteClient#

class flytekit.clients.friendly.SynchronousFlyteClient(cfg, **kwargs)[source]#

This is a low-level client that users can use to make direct gRPC service calls to the control plane. See the service spec. This is more user-friendly interface than the raw client so users should try to use this class first. Create a client by

SynchronousFlyteClient("your.domain:port", insecure=True)
# insecure should be True if your flyteadmin deployment doesn't have SSL enabled

Initializes a gRPC channel to the given Flyte Admin service.

Parameters

  • url – The server address.

  • insecure – if insecure is desired

  • cfg (PlatformConfig) –

Methods

create_download_location(create_download_location_request)#

Get a signed url to be used during fast registration :param flyteidl.service.dataproxy_pb2.CreateDownloadLocationRequest create_download_location_request: :rtype: flyteidl.service.dataproxy_pb2.CreateDownloadLocationResponse

create_execution(project, domain, name, execution_spec, inputs)[source]#

This will create an execution for the given execution spec. :param Text project: :param Text domain: :param Text name: :param flytekit.models.execution.ExecutionSpec execution_spec: This is the specification for the execution. :param flytekit.models.literals.LiteralMap inputs: The inputs for the execution :returns: The unique identifier for the execution. :rtype: flytekit.models.core.identifier.WorkflowExecutionIdentifier

create_launch_plan(launch_plan_identifer, launch_plan_spec)[source]#

This will create a launch plan definition in the Admin database. Once successful, the launch plan object can be retrieved via the client or viewed via the UI or command-line interfaces.

Note

Overwrites are not supported so any request for a given project, domain, name, and version that exists in the database must match the existing definition exactly. This also means that as long as the request remains identical, calling this method multiple times will result in success.

Param

flytekit.models.core.identifier.Identifier launch_plan_identifer: The identifier for this launch plan.

Param

flytekit.models.launch_plan.LaunchPlanSpec launch_plan_spec: This is the actual definition of the launch plan that should be created.

Raises

  • flytekit.common.exceptions.user.FlyteEntityAlreadyExistsException – If an identical version of the launch plan is found, this exception is raised. The client might choose to ignore this exception because the identical launch plan is already registered.

  • grpc.RpcError –

create_task(task_identifer, task_spec)[source]#

This will create a task definition in the Admin database. Once successful, the task object can be retrieved via the client or viewed via the UI or command-line interfaces.

Note

Overwrites are not supported so any request for a given project, domain, name, and version that exists in the database must match the existing definition exactly. Furthermore, as long as the request remains identical, calling this method multiple times will result in success.

Parameters

  • task_identifer (flytekit.models.core.identifier.Identifier) – The identifier for this task.

  • task_spec (flytekit.models.task.TaskSpec) – This is the actual definition of the task that should be created.

Raises

  • flytekit.common.exceptions.user.FlyteEntityAlreadyExistsException – If an identical version of the task is found, this exception is raised. The client might choose to ignore this exception because the identical task is already registered.

Note

Overwrites are not supported so any request for a given project, domain, name, and version that exists in the database must match the existing definition exactly. Furthermore, as long as the request remains identical, calling this method multiple times will result in success.

Param

flytekit.models.core.identifier.Identifier workflow_identifier: The identifier for this workflow.

Param

flytekit.models.admin.workflow.WorkflowSpec workflow_spec: This is the actual definition of the workflow that should be created.
