You can use `DOCKER_CONTENT_TRUST=1` to verify the integrity of the images. +* Bitnami container images are released on a regular basis with the latest distribution packages available. + +## Supported tags and respective `Dockerfile` links + +Learn more about the Bitnami tagging policy and the difference between rolling tags and immutable tags [in our documentation page](https://docs.bitnami.com/tutorials/understand-rolling-tags-containers/). + + +* [`2`, `2-debian-11`, `2.3.3`, `2.3.3-debian-11-r4`, `latest` (2/debian-11/Dockerfile)](https://github.com/bitnami/bitnami-docker-airflow-worker/blob/2.3.3-debian-11-r4/2/debian-11/Dockerfile) + +Subscribe to project updates by watching the [bitnami/airflow GitHub repo](https://github.com/bitnami/bitnami-docker-airflow-worker). + +## Prerequisites + +To run this application you need [Docker Engine](https://www.docker.com/products/docker-engine) >= `1.10.0`.

Hence, you will need to rest of Airflow components for this image to work. +You will need an [Airflow Webserver](https://www.github.com/bitnami/bitnami-docker-airflow), an [Airflow Scheduler](https://www.github.com/bitnami/bitnami-docker-airflow-scheduler), a [PostgreSQL database](https://www.github.com/bitnami/bitnami-docker-postgresql) and a [Redis(R) server](https://www.github.com/bitnami/bitnami-docker-redis). + +### Using Docker Compose + +The main folder of this repository contains a functional [`docker-compose.yml`](https://github.com/bitnami/bitnami-docker-airflow-worker/blob/master/docker-compose.yml) file. Run the application using it as shown below: + +```console +$ curl -sSL https://raw.githubusercontent.com/bitnami/bitnami-docker-airflow-worker/master/docker-compose.yml > docker-compose.yml +$ docker-compose up -d +``` + +### Using the Docker Command Line + +If you want to run the application manually instead of using `docker-compose`, these are the basic steps you need to run: + +1. Create a network + + ```console + $ docker network create airflow-tier + ``` + +2.

This means that Airflow does not persist anything. To avoid loss of data, you should mount volumes for persistence of [PostgreSQL data](https://github.com/bitnami/bitnami-docker-mariadb#persisting-your-database) and [Redis(R) data](https://github.com/bitnami/bitnami-docker-redis#persisting-your-database) + +The above examples define docker volumes namely `postgresql_data`, and `redis_data`. The Airflow application state will persist as long as these volumes are not removed. + +To avoid inadvertent removal of these volumes you can [mount host directories as data volumes](https://docs.docker.com/engine/tutorials/dockervolumes/). Alternatively you can make use of volume plugins to host the volume data. + +#### Mount host directories as data volumes with Docker Compose + +The following `docker-compose.yml` template demonstrates the use of host directories as data volumes. + +```yaml +version: '2' +services: + postgresql: + image: 'bitnami/postgresql:latest' + environment: + - POSTGRESQL_DATABASE=bitnami_airflow + - POSTGRESQL_USERNAME=bn_airflow + - POSTGRESQL_PASSWORD=bitnami1 + volumes: + - /path/to/postgresql-persistence:/bitnami + redis: + image: 'bitnami/redis:latest' + environment: + - ALLOW_EMPTY_PASSWORD=yes + volumes: + - /path/to/redis-persistence:/bitnami + airflow-worker: + image: bitnami/airflow-worker:latest + environment: + - AIRFLOW_FERNET_KEY=46BKJoQYlPPOexq0OhDZnIlNepKFf87WFwLbfzqDDho= + - AIRFLOW_SECRET_KEY=a25mQ1FHTUh3MnFRSk5KMEIyVVU2YmN0VGRyYTVXY08= + - AIRFLOW_EXECUTOR=CeleryExecutor + - AIRFLOW_DATABASE_NAME=bitnami_airflow + - AIRFLOW_DATABASE_USERNAME=bn_airflow + - AIRFLOW_DATABASE_PASSWORD=bitnami1 + - AIRFLOW_LOAD_EXAMPLES=yes + airflow-scheduler: + image: bitnami/airflow-scheduler:latest + environment: + - AIRFLOW_FERNET_KEY=46BKJoQYlPPOexq0OhDZnIlNepKFf87WFwLbfzqDDho= + - AIRFLOW_SECRET_KEY=a25mQ1FHTUh3MnFRSk5KMEIyVVU2YmN0VGRyYTVXY08= + - AIRFLOW_EXECUTOR=CeleryExecutor + - AIRFLOW_DATABASE_NAME=bitnami_airflow + - AIRFLOW_DATABASE_USERNAME=bn_airflow + - AIRFLOW_DATABASE_PASSWORD=bitnami1 + - AIRFLOW_LOAD_EXAMPLES=yes + airflow: + image: bitnami/airflow:latest + environment: + - AIRFLOW_FERNET_KEY=46BKJoQYlPPOexq0OhDZnIlNepKFf87WFwLbfzqDDho= + - AIRFLOW_SECRET_KEY=a25mQ1FHTUh3MnFRSk5KMEIyVVU2YmN0VGRyYTVXY08= + - AIRFLOW_EXECUTOR=CeleryExecutor + - AIRFLOW_DATABASE_NAME=bitnami_airflow + - AIRFLOW_DATABASE_USERNAME=bn_airflow + - AIRFLOW_DATABASE_PASSWORD=bitnami1 + - AIRFLOW_PASSWORD=bitnami123 + - AIRFLOW_USERNAME=user + - AIRFLOW_EMAIL=user@example.com + ports: + - '8080:8080' +``` + +#### Mount host directories as data volumes using the Docker command line + +1.
