Apache Airflow with Docker Compose examples

UPD from July 2020: Those articles was created before release of official Apache Airflow Docker image and they use puckel/docker-airflow. Now, already exist official image apache/airflow. So this docker-compose files became 'legacy' and all sources moved to 'docker_with_puckel_image'. Main Docker Compose Cluster based on apache/airflow Image

Docker-compose config based on official image (required docker-compose version 3.7 and higher):

docker-compose-with-celery-executor.yml

And env file with config setting for Airflow (used in docker-compose-with-celery-executor.yml): .env

07.2020:

1. All compose files with puckel_image moved to docker_with_puckel_image
2. Creted docker-compose config based on official image (required docker-compose version 3.7 and higher): docker-compose-with-celery-executor.yml And env file with config setting for Airflow (used in docker-compose-with-celery-executor.yml): .env
3. At the bottom of readme added note for Windows 10 users

21.07.2020:

1. Docker Compose files with puckel images moved to docker_with_puckel_image
2. Added docker-compose-with-celery.yml based on official image.

18.12.19 changes:

1. added samples for article https://medium.com/@xnuinside/install-python-dependencies-to-docker-compose-cluster-without-re-build-images-8c63a431e11c (docker-compose-volume-packages.yml, packages.pth, added commented lines to Dockerfile)
2. added .dockerignore

29.11.19 changes:

1. Apache Airflow Image was updated to version 1.10.6
2. Added test_dag into airflow_files

For Windows 10 Users

If you try to work on Windows 10 & run docker-compose on it you will got an issue for postgres service:

FATAL: data directory "/var/lib/postgresql/data/pgdata" has wrong ownership

To solve this issue you must do additional steps (unfortanutely there is no more quick workaround, check: https://forums.docker.com/t/data-directory-var-lib-postgresql-data-pgdata-has-wrong-ownership/17963/23 and https://forums.docker.com/t/trying-to-get-postgres-to-work-on-persistent-windows-mount-two-issues/12456/5?u=friism):

1. Create docker volume:

   docker volume create --name volume-postgresql -d local

2. in docker-compose.yml: 2.1 add volume at thetop of the file, under 'networks' defining like this:

   networks:
     airflow:
   
   volumes:
     volume-postgresql:
       external: true
   

   2.2 change postgres service volumes:

    was:  
   

     - ./database/data:/var/lib/postgresql/data/pgdata
     - ./database/logs:/var/lib/postgresql/data/log
   

    become:
   

     - volume-postgresql:/var/lib/postgresql/data/pgdata
     - volume-postgresql:/var/lib/postgresql/data/log
   

Or use WSL and run docker under it.

If you never use docker with mount local folders as volumes under WSL possible you need first follow up this article: https://nickjanetakis.com/blog/setting-up-docker-for-windows-and-wsl-to-work-flawlessly#ensure-volume-mounts-work because by default volumes are not mounted correct and you will not see any 'dags' in Airflow.
