Before you initialize db with next command, make sure that the directory "/airflow" exists and file "/airflow/airflow.cfg" has following options properly set:

dags_folder = dag directory path of this project  
load_examples = False (This is optional to avoid confusion with airflow implemented dags)  
executor = LocalExecutor  

We are using LocalExecutor as we are exploring airflow and haven't really moved to production deployment yet.

To init the airflow db
fab initdb

Following will run airflow webserver and you can check ui on localhost:8083
fab runserver
Note that above command wont run in background so you need another terminal window and run following command in it.
source pyenv/bin/activate

You can take a look at example implementation of dags in directory "airflow-for-workflows/dags" Following command will run unit tests but we don't have any yet :(.
fab test

Feel free to explore new operator and add example implementation here.

You can simply try out example dags from "dags" directory using following command and observe it in UI(localhost:8083)
