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.

tests/system/providers/amazon/aws/example_ec2.py[source]

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

Stop an Amazon EC2 instance¶

To stop an Amazon EC2 instance you can use EC2StopInstanceOperator.

tests/system/providers/amazon/aws/example_ec2.py[source]

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

Sensors¶

Wait on an Amazon EC2 instance state¶

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

tests/system/providers/amazon/aws/example_ec2.py[source]

await_instance = EC2InstanceStateSensor(
    task_id="await_instance",
    instance_id=instance_id,
    target_state="running",
)
