Amazon Amazon Elastic Compute Cloud (EC2)¶

Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides resizable computing capacity—literally, servers in Amazon's data centers—that you use to build and host your software systems.

Prerequisite Tasks¶

To use these operators, you must do a few things:

Create necessary resources using AWS Console or AWS CLI.
Install API libraries via pip.
pip install 'apache-airflow[amazon]'
Detailed information is available Installation
Setup Connection.

Operators¶

Start an Amazon EC2 instance¶

To start an Amazon EC2 instance you can use EC2StartInstanceOperator.

airflow/providers/amazon/aws/example_dags/example_ec2.py[source]

start_instance = EC2StartInstanceOperator(
    task_id="ec2_start_instance",
    instance_id=INSTANCE_ID,
)

Stop an Amazon EC2 instance¶

To stop an Amazon EC2 instance you can use EC2StopInstanceOperator.

airflow/providers/amazon/aws/example_dags/example_ec2.py[source]

stop_instance = EC2StopInstanceOperator(
    task_id="ec2_stop_instance",
    instance_id=INSTANCE_ID,
)

Sensors¶

Amazon EC2 instance state sensor¶

To check the state of an Amazon EC2 instance and wait until it reaches the target state you can use EC2InstanceStateSensor.

airflow/providers/amazon/aws/example_dags/example_ec2.py[source]

instance_state = EC2InstanceStateSensor(
    task_id="ec2_instance_state",
    instance_id=INSTANCE_ID,
    target_state="running",
)
