Christian Barra created AIRFLOW-2665:
----------------------------------------
Summary: No BASH will cause a the dag to fail
Key: AIRFLOW-2665
URL: https://issues.apache.org/jira/browse/AIRFLOW-2665
Project: Apache Airflow
Issue Type: Bug
Reporter: Christian Barra
If you are a running airflow in a system where bash is not available the dags
will fail, with no logs inside the UI (you have to scroll trough the local
logs).
How to replicate this? just use an alpine based image:
```
