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

## 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.
