StartTaskInformation Class

  • Reference

Information about a StartTask running on a Compute Node.

All required parameters must be populated in order to send to Azure.

Inheritance
msrest.serialization.Model
StartTaskInformation

Constructor

StartTaskInformation(*, state, start_time, retry_count: int, end_time=None, exit_code: int = None, container_info=None, failure_info=None, last_retry_time=None, result=None, **kwargs)

Parameters

Name Description
state
Required
str or StartTaskState

Required. Possible values include: 'running', 'completed'
start_time
Required
datetime

Required. This value is reset every time the Task is restarted or retried (that is, this is the most recent time at which the StartTask started running).
end_time
Required
datetime

This is the end time of the most recent run of the StartTask, if that run has completed (even if that run failed and a retry is pending). This element is not present if the StartTask is currently running.
exit_code
Required
int

The exit code of the program specified on the StartTask command line. This property is set only if the StartTask is in the completed state. In general, the exit code for a process reflects the specific convention implemented by the application developer for that process. If you use the exit code value to make decisions in your code, be sure that you know the exit code convention used by the application process. However, if the Batch service terminates the StartTask (due to timeout, or user termination via the API) you may see an operating system-defined exit code.
container_info
Required
TaskContainerExecutionInformation

Information about the container under which the Task is executing. This property is set only if the Task runs in a container context.
failure_info
Required
TaskFailureInformation

Information describing the Task failure, if any. This property is set only if the Task is in the completed state and encountered a failure.
retry_count
Required
int

Required. The number of times the Task has been retried by the Batch service. Task application failures (non-zero exit code) are retried, pre-processing errors (the Task could not be run) and file upload errors are not retried. The Batch service will retry the Task up to the limit specified by the constraints.
last_retry_time
Required
datetime

This element is present only if the Task was retried (i.e. retryCount is nonzero). If present, this is typically the same as startTime, but may be different if the Task has been restarted for reasons other than retry; for example, if the Compute Node was rebooted during a retry, then the startTime is updated but the lastRetryTime is not.
result
Required
str or TaskExecutionResult

The result of the Task execution. If the value is 'failed', then the details of the failure can be found in the failureInfo property. Possible values include: 'success', 'failure'

Keyword-Only Parameters

Methods

as_dict

Return a dict that can be JSONify using json.dump.

Advanced usage might optionally use a callback as parameter:

Key is the attribute name used in Python. Attr_desc is a dict of metadata. Currently contains 'type' with the msrest type and 'key' with the RestAPI encoded key. Value is the current value in this object.

The string returned will be used to serialize the key. If the return type is a list, this is considered hierarchical result dict.

See the three examples in this file:

  • attribute_transformer

  • full_restapi_key_transformer

  • last_restapi_key_transformer

If you want XML serialization, you can pass the kwargs is_xml=True.
deserialize

Parse a str using the RestAPI syntax and return a model.
enable_additional_properties_sending
from_dict

Parse a dict using given key extractor return a model.

By default consider key extractors (rest_key_case_insensitive_extractor, attribute_key_case_insensitive_extractor and last_rest_key_case_insensitive_extractor)
is_xml_model
serialize

Return the JSON that would be sent to azure from this model.

This is an alias to as_dict(full_restapi_key_transformer, keep_readonly=False).

If you want XML serialization, you can pass the kwargs is_xml=True.
validate

Validate this model recursively and return a list of ValidationError.
