godatadriven/airflow repository overview

⁠Apache Airflow in Docker

Airflow docker container based on Miniconda

⁠Running the container

By default airflow --help is run:

docker run godatadriven/airflow 

To run the webserver, try our upgradedb_webserver command which first runs upgradedb (inits and upgrades the airflow database) before it starts the webserver

docker run godatadriven/airflow upgradedb_webserver

⁠Adding dependencies

When starting the container, the entrypoint script will look for additional dependencies to install in /dependencies. It will install:

• Debian dependencies specified in /dependencies/packages.txt
• Pip dependencies specified in /dependencies/requirements.txt
• Conda dependencies specified in /dependencies/environment.yml

In the dependencies_example folder we've included some examples.

Additionally, you can customize the container at runtime with a pre and post hook. These will be called before, and after calling upgrade db.

⁠Docker compose

We've build three compose files which use postgresql as a database.

• The first compose file starts the webserver and localexecutor as separate containers.
• The second compose file uses celery to communicate with the executors.
• Finally the last compose file shows how to add additional dependencies at runtime.
