Airflow will evaluate the exit code of the bash command. In general, a non-zero exit code will result in task failure and zero will result in task success. Exit code 99 (or another set in skip_on_exit_code ) will throw an airflow.exceptions.AirflowSkipException, which will leave the task in skipped state. You can have all non-zero exit codes be ...class airflow.operators.empty.

SSL can be enabled by providing a certificate and key. Once enabled, be sure to use “ https:// ” in your browser. [webserver] web_server_ssl_cert = <path to cert> web_server_ssl_key = <path to key>.

Configuration Reference. This page contains the list of all the available Airflow configurations that you can set in airflow.cfg file or using environment variables. Use the same configuration across all the Airflow components. While each component does not require all, some configurations need to be same otherwise they would not work as expected.

10. Judging from the source code, it would appear as though parameters can be passed into the dag run. If the body of the http request contains json, and that json contains a top level key conf the value of the conf key will be passed as configuration to trigger_dag. More on how this works can be found here.

DAGs. A DAG (Directed Acyclic Graph) is the core concept of Airflow, collecting Tasks together, organized with dependencies and relationships to say how they should run. It defines four Tasks - A, B, C, and D - and dictates the order in which they have to run, and which tasks depend on what others. To do this, you should use the --imgcat switch in the airflow dags show command. For example, if you want to display example_bash_operator DAG then you can use the following command: airflow dags show example_bash_operator --imgcat. You will see a similar result as in the screenshot below. Preview of DAG in iTerm2. DAGs.
