![]() By utilizing BashOperator, we create a somewhat creative output of “HelloWorld!”. The EmptyOperator serves no real purpose other than to create a mockup task inside the Web UI. We define a new DAG and some pretty simple tasks. Just head over to the terminal and spin up all the necessary containers by runningįrom import EmptyOperatorįrom import BashOperator Note: More information on the different kinds of executors can be found here. In our case, we make use of the LocalExecutor. Most importantly, the kind of executor Airflow we will utilize. The above variables set the database credentials, the airflow user, and some further configurations. env file with the following content:ĪIRFLOW_CORE_FERNET_KEY=UKMzEm3yIuFYEq1圓-2FxPNWSVwRASpahmQ9kQfEr8E=ĪIRFLOW_CORE_DAGS_ARE_PAUSED_AT_CREATION=True ![]() Still, inside your Airflow folder create a. However, to complete the installation process and configure Airflow properly, we need to provide some environment variables. We successfully created a docker-compose file with the mandatory services inside. Most importantly the scheduler, the webserver, the metadatabase (PostgreSQL), and the airflow-init job initializing the database.Īt the top of the file, we make use of some local variables that are commonly used in every docker container or service. The above docker-compose file simply specifies the required services we need to get Airflow up and running. Mkdir -p /sources/logs /sources/dags /sources/pluginsĬhown -R "$ var/run/docker.sock:/var/run/docker.sockĬondition: service_completed_successfully Just navigate via your preferred terminal to a directory, create a new folder, and change into it by running: We start nice and slow by simply creating a new folder for Airflow. Simply head over to the official Docker site and download the appropriate installation file for your OS. Since we will use docker-compose to get Airflow up and running, we have to install Docker first. Now that we shortly introduced Apache Airflow, it’s time to get started.
