Setup Instruction

fulfill docker + docker-compose prerequisites in the airflow
run the following code to export environment variables for airflow

mkdir -p ./dags ./logs ./plugins
echo -e "AIRFLOW_UID=$(id -u)" > .env
# AIRFLOW_GID=0 may be needed
echo -e "AIRFLOW_GID=0" >> .env

init airflow

docker-compose up --build airflow-init

execute docker-compose to build the services in this stack

docker-compose up

if running in daemon is preferred

docker-compose up -d

Airflow UI

Stopping Airflow with docker compose down

docker-compose down

to remove images, docker-compose down --volumes and add --rmi all

additional commands:

stop all docker containers

docker kill $(docker ps -q)

remove all docker containers

docker rm $(docker ps -a -q)

prune all volumes

docker system prune -a --volumes
