# Bitnami package for Apache Airflow

## What is Apache Airflow?

> Apache Airflow is a tool to express and execute workflows as directed acyclic graphs (DAGs). It includes utilities to schedule tasks, monitor task progress and handle task dependencies.

## Why use Bitnami Images?

* Bitnami closely tracks upstream source changes and promptly publishes new versions of this image using our automated systems.
* With Bitnami images the latest bug fixes and features are available as soon as possible.
* Bitnami containers, virtual machines and cloud images use the same components and configuration approach - making it easy to switch between formats based on your project needs.
* All our images are based on [**minideb**](https://github.com/bitnami/minideb) -a minimalist Debian based container image that gives you a small base container image and the familiarity of a leading Linux distribution- or **scratch** -an explicitly empty image-.
* All Bitnami images available in Docker Hub are signed with [Docker Content Trust (DCT)](https://docs.docker.com/engine/security/trust/content_trust/). 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/).

You can see the equivalence between the different tags by taking a look at the `tags-info.yaml` file present in the branch folder, i.e `bitnami/ASSET/BRANCH/DISTRO/tags-info.yaml`.

## Prerequisites

To run this application you need [Docker Engine](https://www.docker.com/products/docker-engine) >= `1.10.0`. [Docker Compose](https://docs.docker.com/compose/) is recommended with a version `1.6.0` or later.

## How to use this image

Airflow requires access to a PostgreSQL database to store information. We will use our very own [PostgreSQL image](https://github.com/bitnami/containers/tree/main/bitnami/postgresql) for the database requirements. Additionally, if you pretend to use the `CeleryExecutor`, you will also need an [Airflow Scheduler](https://github.com/bitnami/containers/tree/main/bitnami/airflow-scheduler), one or more [Airflow Workers](https://github.com/bitnami/containers/tree/main/bitnami/airflow-worker) and a [Redis(R) server](https://github.com/bitnami/containers/tree/main/bitnami/redis).

### Using the Docker Command Line

1. Create a network

    ```console
    docker network create airflow-tier
    ```

2. Create a volume for PostgreSQL persistence and create a PostgreSQL container

    ```console
    docker volume create --name postgresql_data
    docker run -d --name postgresql \
      -e POSTGRESQL_USERNAME=bn_airflow \
      -e POSTGRESQL_PASSWORD=bitnami1 \
      -e POSTGRESQL_DATABASE=bitnami_airflow \
      --net airflow-tier \
      --volume postgresql_data:/bitnami/postgresql \
      bitnami/postgresql:latest
    ```

3. Create a volume for Redis(R) persistence and create a Redis(R) container

    ```console
    docker volume create --name redis_data
    docker run -d --name redis \
      -e ALLOW_EMPTY_PASSWORD=yes \
      --net airflow-tier \
      --volume redis_data:/bitnami \
      bitnami/redis:latest
    ```

4. Launch the Apache Airflow web container

    ```console
    docker run -d --name airflow -p 8080:8080 \
      -e AIRFLOW_FERNET_KEY=46BKJoQYlPPOexq0OhDZnIlNepKFf87WFwLbfzqDDho= \

### Using `docker-compose.yaml`

```console
curl -LO https://raw.githubusercontent.com/bitnami/containers/main/bitnami/airflow/docker-compose.yml
docker-compose up
```

Please be aware this file has not undergone internal testing. Consequently, we advise its use exclusively for development or testing purposes. For production-ready deployments, we highly recommend utilizing its associated [Bitnami Helm chart](https://github.com/bitnami/charts/tree/main/bitnami/airflow).

If you detect any issue in the `docker-compose.yaml` file, feel free to report it or contribute with a fix by following our [Contributing Guidelines](https://github.com/bitnami/containers/blob/main/CONTRIBUTING.md).

### Persisting your application

The Bitnami Airflow container relies on the PostgreSQL database & Redis to persist the data. 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/containers/blob/main/bitnami/mariadb#persisting-your-database) and [Redis(R) data](https://github.com/bitnami/containers/blob/main/bitnami/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_PASSWORD=bitnami1
    volumes:
      - /path/to/postgresql-persistence:/bitnami/postgresql
  redis:
    image: 'bitnami/redis:latest'
    environment:
      - ALLOW_EMPTY_PASSWORD=yes
    volumes:

## Configuration

### Load DAG files

Custom DAG files can be mounted to `/opt/bitnami/airflow/dags`.

### Installing additional python modules

This container supports the installation of additional python modules at start-up time. In order to do that, you can mount a `requirements.txt` file with your specific needs under the path `/bitnami/python/requirements.txt`.

#### Specifying Environment variables on the Docker command line

```console
docker run -d --name airflow -p 8080:8080 \
    -e AIRFLOW_FERNET_KEY=46BKJoQYlPPOexq0OhDZnIlNepKFf87WFwLbfzqDDho= \
    -e AIRFLOW_SECRET_KEY=a25mQ1FHTUh3MnFRSk5KMEIyVVU2YmN0VGRyYTVXY08= \
    -e AIRFLOW_EXECUTOR=CeleryExecutor \
    -e AIRFLOW_DATABASE_NAME=bitnami_airflow \
    -e AIRFLOW_DATABASE_USERNAME=bn_airflow \
    -e AIRFLOW_DATABASE_PASSWORD=bitnami1 \
    -e AIRFLOW_PASSWORD=bitnami123 \
    -e AIRFLOW_USERNAME=user \
    -e AIRFLOW_EMAIL=user@example.com \
    bitnami/airflow:latest
```

#### SMTP Configuration

To configure Airflow to send email using SMTP you can set the following environment variables:

* `AIRFLOW__SMTP__SMTP_HOST`: Host for outgoing SMTP email. Default: **localhost**
* `AIRFLOW__SMTP__SMTP_PORT`: Port for outgoing SMTP email. Default: **25**
* `AIRFLOW__SMTP__SMTP_STARTTLS`: To use TLS communication. Default: **True**
* `AIRFLOW__SMTP__SMTP_SSL`: To use SSL communication. Default: **False**
* `AIRFLOW__SMTP__SMTP_USER`: User of SMTP used for authentication (likely email). No defaults.
* `AIRFLOW__SMTP__SMTP_PASSWORD`: Password for SMTP. No defaults.
* `AIRFLOW__SMTP__SMTP_MAIL_FROM`: To modify the "from email address". Default: **<airflow@example.com>**

This would be an example of SMTP configuration using a GMail account:

* docker-compose (application part):

```yaml
  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=bitnami
      - AIRFLOW_USERNAME=user
      - AIRFLOW_EMAIL=user@email.com
      - AIRFLOW__SMTP__SMTP_HOST=smtp@gmail.com
      - AIRFLOW__SMTP__SMTP_USER=your_email@gmail.com
      - AIRFLOW__SMTP__SMTP_PASSWORD=your_password
      - AIRFLOW__SMTP__SMTP_PORT=587
    ports:
      - '8080:8080'
```

* For manual execution:

```console
docker run -d --name airflow -p 8080:8080 \
    -e AIRFLOW_FERNET_KEY=46BKJoQYlPPOexq0OhDZnIlNepKFf87WFwLbfzqDDho= \
    -e AIRFLOW_SECRET_KEY=a25mQ1FHTUh3MnFRSk5KMEIyVVU2YmN0VGRyYTVXY08= \
    -e AIRFLOW_EXECUTOR=CeleryExecutor \
    -e AIRFLOW_DATABASE_NAME=bitnami_airflow \
    -e AIRFLOW_DATABASE_USERNAME=bn_airflow \
    -e AIRFLOW_DATABASE_PASSWORD=bitnami1 \
    -e AIRFLOW_PASSWORD=bitnami123 \
    -e AIRFLOW_USERNAME=user \
    -e AIRFLOW_EMAIL=user@example.com \
    -e AIRFLOW__SMTP__SMTP_HOST=smtp@gmail.com \
    -e AIRFLOW__SMTP__SMTP_USER=your_email@gmail.com \
    -e AIRFLOW__SMTP__SMTP_PASSWORD=your_password \
    -e AIRFLOW__SMTP__SMTP_PORT=587 \
    bitnami/airflow:latest
```
