使用airflow.providers.amazon.aws.operators.ecs传递环境变量，并在Docker容器中读取它们。

以下是示例代码：

from airflow.providers.amazon.aws.operators.ecs import ECSOperator

task_definition = {
    "containerDefinitions": [
        {
            "name": "example-container",
            "image": "example-image",
            "environment": [
                {
                    "name": "ENV_VAR_1",
                    "value": "value1"
                },
                {
                    "name": "ENV_VAR_2",
                    "value": "value2"
                }
            ],
            "essential": True
        }
    ]
}

ECSOperator(
    task_definition=task_definition,
    task_definition_arn="example-task-definition-arn",
    aws_conn_id="aws_default",
    launch_type="FARGATE",
    platform_version="LATEST",
    region_name="us-east-1",
    cluster="example-cluster",
    network_configuration={
        "awsvpcConfiguration": {
            "subnets": ["example-subnet-1", "example-subnet-2"],
            "securityGroups": ["example-security-group"],
            "assignPublicIp": "ENABLED"
        }
    }
)
