How to spin the webserver up

Prepping

First, get your id:

id -u

Now edit the .env file and swap out 501 for your own.

Run the following command to creat the volumes needed in order to send data to airflow:

mkdir -p ./dags ./logs ./plugins

And this once:

docker-compose up airflow-init

If the exit code is 0 then it's all good.

Running

docker-compose up

After it is up, add a new connection:

  • Name - postgres_default
  • Conn type - postgres
  • Host - localhost
  • Port - 5432
  • Database - airflow
  • Username - airflow
  • Password - airflow
