Key/value pairs representing Airflow configuration variables. Keys are prefixed by their section: core dags_folder={AIRFLOW_HOME}/dags Would be represented as "core.dags_folder": "{AIRFLOW_HOME}/dags" Search the CloudFormation User Guide for AWS::MWAA::Environment for more information about the expected schema for this property.
The version of Apache Airflow to use for the environment. If no value is specified, defaults to the latest version. If you specify a newer version number for an existing environment, the version update requires some service interruption before taking effect. Allowed Values : 1.10.12 | 2.0.2 | 2.2.2 | 2.4.3 | 2.5.1 | 2.6.3 | 2.7.2 | 2.8.1 | 2.9.2 (latest)
The queue ARN for the environment's Celery Executor . Amazon MWAA uses a Celery Executor to distribute tasks across multiple workers. When you create an environment in a shared VPC, you must provide access to the Celery Executor queue from your VPC.
The relative path to the DAGs folder on your Amazon S3 bucket. For example, dags . To learn more, see Adding or updating DAGs .
The VPC endpoint for the environment's Amazon RDS database.
The environment class type. Valid values: mw1.small , mw1.medium , mw1.large . To learn more, see Amazon MWAA environment class .
The Amazon Resource Name (ARN) of the execution role in IAM that allows MWAA to access AWS resources in your environment. For example, arn:aws:iam::123456789:role/my-execution-role . To learn more, see Amazon MWAA Execution role .
The Apache Airflow logs being sent to CloudWatch Logs: DagProcessingLogs , SchedulerLogs , TaskLogs , WebserverLogs , WorkerLogs .
The maximum number of web servers that you want to run in your environment. Amazon MWAA scales the number of Apache Airflow web servers up to the number you specify for MaxWebservers when you interact with your Apache Airflow environment using Apache Airflow REST API, or the Apache Airflow CLI. For example, in scenarios where your workload requires network calls to the Apache Airflow REST API with a high transaction-per-second (TPS) rate, Amazon MWAA will increase the number of web servers up to the number set in MaxWebserers . As TPS rates decrease Amazon MWAA disposes of the additional web servers, and scales down to the number set in MinxWebserers . Valid values: Accepts between 2 and 5 . Defaults to 2 .
The maximum number of workers that you want to run in your environment. MWAA scales the number of Apache Airflow workers up to the number you specify in the MaxWorkers field. For example, 20 . When there are no more tasks running, and no more in the queue, MWAA disposes of the extra workers leaving the one worker that is included with your environment, or the number you specify in MinWorkers .
The minimum number of web servers that you want to run in your environment. Amazon MWAA scales the number of Apache Airflow web servers up to the number you specify for MaxWebservers when you interact with your Apache Airflow environment using Apache Airflow REST API, or the Apache Airflow CLI. As the transaction-per-second rate, and the network load, decrease, Amazon MWAA disposes of the additional web servers, and scales down to the number set in MinxWebserers . Valid values: Accepts between 2 and 5 . Defaults to 2 .
The minimum number of workers that you want to run in your environment. MWAA scales the number of Apache Airflow workers up to the number you specify in the MaxWorkers field. When there are no more tasks running, and no more in the queue, MWAA disposes of the extra workers leaving the worker count you specify in the MinWorkers field. For example, 2 .
The VPC networking components used to secure and enable network traffic between the AWS resources for your environment. To learn more, see About networking on Amazon MWAA .
The version of the plugins.zip file on your Amazon S3 bucket. To learn more, see Installing custom plugins .
The relative path to the plugins.zip file on your Amazon S3 bucket. For example, plugins.zip . To learn more, see Installing custom plugins .
The version of the requirements.txt file on your Amazon S3 bucket. To learn more, see Installing Python dependencies .
The relative path to the requirements.txt file on your Amazon S3 bucket. For example, requirements.txt . To learn more, see Installing Python dependencies .
The number of schedulers that you want to run in your environment. Valid values:
The Amazon Resource Name (ARN) of the Amazon S3 bucket where your DAG code and supporting files are stored. For example, arn:aws:s3:::my-airflow-bucket-unique-name . To learn more, see Create an Amazon S3 bucket for Amazon MWAA .
The version of the startup shell script in your Amazon S3 bucket. You must specify the version ID that Amazon S3 assigns to the file every time you update the script. Version IDs are Unicode, UTF-8 encoded, URL-ready, opaque strings that are no more than 1,024 bytes long. The following is an example: 3sL4kqtJlcpXroDTDmJ+rmSpXd3dIbrHY+MTRCxf3vjVBH40Nr8X8gdRQBpUMLUo For more information, see Using a startup script .
The relative path to the startup shell script in your Amazon S3 bucket. For example, s3://mwaa-environment/startup.sh . Amazon MWAA runs the script as your environment starts, and before running the Apache Airflow process. You can use this script to install dependencies, modify Apache Airflow configuration options, and set environment variables. For more information, see Using a startup script .
A map of tags for the environment. Search the CloudFormation User Guide for AWS::MWAA::Environment for more information about the expected schema for this property.
The Apache Airflow Web server access mode. To learn more, see Apache Airflow access modes . Valid values: PRIVATE_ONLY or PUBLIC_ONLY .
