airflow log가 제대로 안나올 때

아래처럼만 나오고 제대로된 log가 안뜬다.. 

*** Log file does not exist: /opt/bitnami/airflow/logs/tutorial/hello_task/2021-11-05T06:36:04.378967+00:00/1.log

아래 링크에 가면 그냥 Environment Variables만 알려주고 무슨 값을 넣어야하는지도 안알려준다. ㅡㅡ

Configuration Reference — Airflow Documentation

 

그러던 와중에 아래 사이트에서 그냥 진짜 랜덤값 넣어주면 돼! 라고했다.

https://serverfault.com/questions/947745/in-airflows-configuration-file-airflow-cfg-what-is-the-secret-key-and-do-i

In airflow's configuration file `airflow.cfg` what is the `secret_key`, and do I have to set it?

그냥 아래 명령어로 랜덤값을 얻어서 Environment Variables에 입력한다.

python -c 'import os; print(os.urandom(16))'

[후략...]에어 플로우에 관련된 모든 컴포넌트 동일

 

그럼 아래와같이 잘 뜬다.
