        # Amazon Managed Workflows for Apache Airflow(MWAA) Module

This terraform module can be used to deploy [Amazon Managed Workflows for Apache Airflow(MWAA)](https://docs.aws.amazon.com/mwaa/latest/userguide/what-is-mwaa.html) environment.

   ✅ Deployment examples can be found under [examples](https://github.com/aws-ia/terraform-aws-mwaa/tree/main/examples) folder.

   ✅ Amazon MWAA documentation for more details about [Amazon MWAA](https://docs.aws.amazon.com/mwaa/index.html)

   ✅ Amazon MWAA for Analytics [Workshop](https://catalog.us-east-1.prod.workshops.aws/workshops/795e88bb-17e2-498f-82d1-2104f4824168/en-US)

## Amazon MWAA Architecture



  



## Usage

The example below builds Amazon MWAA environment with existing VPC and Private Subnets.

Amazon MWAA supporting resources S3 bucket, IAM role and Security groups created by this module by default.

This module allows you to bring your own S3 bucket, IAM role and Security group.

```hcl

module "mwaa" {

  source = "aws-ia/mwaa/aws"

  name                 = "basic-mwaa"

  airflow_version      = "2.2.2"

  environment_class    = "mw1.medium"

  vpc_id                = ""

  private_subnet_ids    = ["",""]

  min_workers           = 1

  max_workers           = 25

  webserver_access_mode = "PUBLIC_ONLY" # Default PRIVATE_ONLY for production environments

  iam_role_additional_policies = {

    "additional-policy-1" = ""

    "additional-policy-2" = ""

  }

  logging_configuration = {

    dag_processing_logs = {

      enabled   = true

      log_level = "INFO"

    }

    scheduler_logs = {

      enabled   = true

      log_level = "INFO"

    }

    task_logs = {

      enabled   = true

      log_level = "INFO"

    }

    webserver_logs = {

      enabled   = true

      log_level = "INFO"

    }

    worker_logs = {

      enabled   = true

      log_level = "INFO"

    }

  }

  airflow_configuration_options = {

    "core.load_default_connections" = "false"

    "core.load_examples"            = "false"

    "webserver.dag_default_view"    = "tree"

    "webserver.dag_orientation"     = "TB"

    "logging.logging_level"         = "INFO"

  }

}
