It helps organizations to schedule their tasks so that they are executed when the right time comes. 'start_date': dt.Airflow is a task automation tool. 'dag_id': 'schedule_interval_bug_example_dag', Your DAG will be instantiated for each schedule along with a corresponding DAG Run entry in the database backend.įrom _operator import DummyOperator Cron Presetsĭon't schedule, use for exclusively 'externally triggered' once and only once an hour at the beginning of the hourĠ 0 * * once a week at midnight on Sunday morningĠ 0 * * once a month at midnight of the first day of the monthĠ 0 1 * once a quarter at midnight on the first dayĠ 0 1 */3 once a year at midnight of January 1 schedule_interval is defined as a DAG argument, which can be passed a cron expression as a str, a datetime.timedelta object, or one of the following cron 'presets'. DAG Runs can run in parallel for the same DAG, and each has a defined execution_date, which identifies the logical date and time it is running for - not the actual time when it was started.Ī DAG Run is an object representing an instantiation of the DAG in time.Įach DAG may or may not have a schedule, which informs how DAG Runs are created. You define it via the schedule_interval argument, like this: with DAG('my_daily_dag', schedule_interval argument takes any value that is a valid Crontab schedule value, so you could also do: with DAG('my_daily_dag', schedule_interval='0 * * * *'):Įvery time you run a DAG, you are creating a new instance of that DAG which Airflow calls a DAG Run.

On a defined schedule, which is defined as part of the DAGĭAGs do not require a schedule, but it's very common to define one. When they are triggered either manually or via the API Time zone information is exposed and it is up to the writer of DAG what do with it. Also templates used in Operators are not converted. There it will always be displayed in UTC. At the moment Airflow does not convert them to the end user’s time zone in the user interface. It allows you to run your DAGs with time zone dependent schedules. Airflow stores datetime information in UTC internally and in the database. Support for time zones is enabled by default. S = sched.scheduler(time.time, time.sleep) If you want to trigger this dag manually then you need to set scheduling_interval=None and use airflow trigger_dag dag_id (Documentation : airflow trigger dag) Please raise an issue in github if you encounter any such issues. NOTE: The Apache Airflow Client is still under active development and some methods or APIs might be broken. 项目还在开发，有些API是坏的。 Apache Airflow Python Client JSON object describing additional configuration parameters. This together with DAG_ID are a unique key. If you try to modify the field of an existing object, the request fails with an BAD_REQUEST error. The value of this field can be set only when creating the object. This is the time when the DAG run should be started according to the DAG definition. If the specified dag_run_id is in use, the creation request fails with an ALREADY_EXISTS error. If not provided, a value will be generated based on execution_date. Request Body schema: application/json dag_run_id Trigger a new DAG run path Parameters dag_id

$ airflow config get-value api auth_backendįor details on configuring the authentication, see API Authorization. If you want to check which auth backend is currently set, you can use airflow config get-value api auth_backend command as in the example below. To be able to meet the requirements of many organizations, Airflow supports many authentication methods, and it is even possible to add your own method.

To enable basic authentication, set the following in the configuration: Īuth_backend = .basic_auth This works for users created through LDAP login or within Airflow Metadata DB using password.

默认API是关闭的，需要调整为鉴权认证模式。 Basic authenticationīasic username password authentication is currently supported for the API. This means that you must usually add the following headers to your request: Content-type: application/json Most of the endpoints accept JSON as input and return JSON responses. This section provides an overview of the API design, methods, and supported use cases. To facilitate management, Apache Airflow supports a range of REST API endpoints across its objects. 标签： dag run airflow id trigger apache DAG REST API
