## Quick Start
```bash
$ docker stack deploy -c docker-stack.yaml airflow
$ docker stack services airflow
$ docker service ps airflow_webserver
$ docker exec -it airflow_webserver.1.xxxxxx sh
>>> airflow create_user -r Admin -u admin -e admin@borderxlab.com -f Super -l Admin -p secret
>>> airflow list_users
╒══════╤════════════╤══════════════════════╤══════════════╤═════════════╤═════════╕
│ Id │ Username │ Email │ First name │ Last name │ Roles │
╞══════╪════════════╪══════════════════════╪══════════════╪═════════════╪═════════╡
1 │ admin │ admin@borderxlab.com │ Super │ Admin │ [Admin]
╘══════╧════════════╧══════════════════════╧══════════════╧═════════════╧═════════╛
>>> exit
$ curl http://localhost:8080/
$ curl http://localhost:5555/
```
> :warning: You need to prepare nfs server with `airflow.cfg`.
```bash
$ python -c 'from cryptography.fernet import Fernet; print(Fernet.generate_key().decode())'

```
> :warning: You should set another value to `fernet_key` in `airflow.cfg` to improve security.
