Using Docker and docker-compose to manage Apache Airflow on mac

Using our beloved docker and docker-compose, we can very quickly bring up an Apache Airflow instance on our mac.

Contents of docker-compose.yml

About the only thing you need to customize in this docker-compose.yml file is the volumes section. This will tell docker to map the given directory containing your Airflow DAGs/plugins to container file system.

How to start airflow?

Ans: Simply use docker-compose up. Assuming you have a docker-compose.yml file in the pwd.

Note: If you don't want to see logs, just use docker-compose up -d

How to shutdown airflow containers?

Ans: This will just stop the containers, it won't remove them.

(airflow) Shravan: airflow$ docker-compose stop
Stopping airflow_webserver_1 ... done
Stopping airflow_postgres_1  ... done

How to shutdown airflow containers and remove the containers ?

Ans: When you make changes to docker-compose, and you wish to start fresh.

(airflow) Shravan: airflow$ docker-compose down
Removing airflow_webserver_1 ... done
Removing airflow_postgres_1  ... done
Removing network airflow_default

(airflow) Shravan: airflow$ docker-compose ps
Name   Command   State   Ports
------------------------------

(OPTIONAL) Create a new environment for airflow:

STEP 1: conda create --no-default-packages -n airflow python=3.6

STEP 2: conda activate airflow

STEP 3: pip install apache-airflow[postgres,s3] --no-cache-dir

The --no-cache-dir option will force pip to go and retrieve instead of being a lazy-bum and reading from cache.
