JobReleaseTask Class

A Job Release Task to run on Job completion on any Compute Node where the Job has run.

The Job Release Task runs when the Job ends, because of one of the following: The user calls the Terminate Job API, or the Delete Job API while the Job is still active, the Job's maximum wall clock time constraint is reached, and the Job is still active, or the Job's Job Manager Task completed, and the Job is configured to terminate when the Job Manager completes. The Job Release Task runs on each Node where Tasks of the Job have run and the Job Preparation Task ran and completed. If you reimage a Node after it has run the Job Preparation Task, and the Job ends without any further Tasks of the Job running on that Node (and hence the Job Preparation Task does not re-run), then the Job Release Task does not run on that Compute Node. If a Node reboots while the Job Release Task is still running, the Job Release Task runs again when the Compute Node starts up. The Job is not marked as complete until all Job Release Tasks have completed. The Job Release Task runs in the background. It does not occupy a scheduling slot; that is, it does not count towards the taskSlotsPerNode limit specified on the Pool.

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

JobReleaseTask

Constructor

JobReleaseTask(*, command_line: str, id: str = None, container_settings=None, resource_files=None, environment_settings=None, max_wall_clock_time=None, retention_time=None, user_identity=None, **kwargs)

Parameters

Name Description
id
Required
str

The ID can contain any combination of alphanumeric characters including hyphens and underscores and cannot contain more than 64 characters. If you do not specify this property, the Batch service assigns a default value of 'jobrelease'. No other Task in the Job can have the same ID as the Job Release Task. If you try to submit a Task with the same id, the Batch service rejects the request with error code TaskIdSameAsJobReleaseTask; if you are calling the REST API directly, the HTTP status code is 409 (Conflict).

command_line
Required
str

Required. The command line does not run under a shell, and therefore cannot take advantage of shell features such as environment variable expansion. If you want to take advantage of such features, you should invoke the shell in the command line, for example using "cmd /c MyCommand" in Windows or "/bin/sh -c MyCommand" in Linux. If the command line refers to file paths, it should use a relative path (relative to the Task working directory), or use the Batch provided environment variable (https://docs.microsoft.com/en-us/azure/batch/batch-compute-node-environment-variables).

container_settings
Required

The settings for the container under which the Job Release Task runs. When this is specified, all directories recursively below the AZ_BATCH_NODE_ROOT_DIR (the root of Azure Batch directories on the node) are mapped into the container, all Task environment variables are mapped into the container, and the Task command line is executed in the container. Files produced in the container outside of AZ_BATCH_NODE_ROOT_DIR might not be reflected to the host disk, meaning that Batch file APIs will not be able to access those files.

resource_files
Required

Files listed under this element are located in the Task's working directory.

environment_settings
Required
max_wall_clock_time
Required
<xref:timedelta>
retention_time
Required
<xref:timedelta>

The default is 7 days, i.e. the Task directory will be retained for 7 days unless the Compute Node is removed or the Job is deleted.

user_identity
Required

The user identity under which the Job Release Task runs. If omitted, the Task runs as a non-administrative user unique to the Task.

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.
