Using .sh for BashOperator

Background: I have a simple script in the worker to be run, something like /usr/src/app/script.sh

In here It’s stated that BashOperator can be used for running script.

while as in tutorial / the actual logic, it is always treated as template file path, being lookup & TemplateNotFound error from jinja will be resulted.

so - is it supposed to run bash script in the target container or it’s always required to use a template as wrapper?

Not sure if it is consistent to turn on the template feature for files only if a separated argument bash_template_file is used?

e.g.

t1 = BashOperator(
    task_id='script1',
    bash_template_file='/usr/src/app/script.sh',
    dag=dag)

I agree, though I can’t break compatibility at this point. I agree that we should clarify the BashOperator parameters, other people have been confused using it.

One path of solution is to add that folder to your template_searchpath as you construct your DAG. https://github.com/airbnb/airflow/blob/master/airflow/models.py#L1530

dag = DAG(dag_id='mydag', template_searchpath="/usr/src/app/")

t1 = BashOperator(
    task_id='script1',
    bash_template_file='script.sh',
    dag=dag)
