I’m trying to reduce the size of official Airflow docker-compose build. The question is about airflow-triggerer container. Seems like if I remove this container – nothing should change, because the scheduler triggers tasks. So, what is the role of airflow-triggerer?

A .airflowignore file specifies the directories or files in DAG_FOLDER that Airflow should intentionally ignore. Each line in .airflowignore specifies a regular expression pattern, and directories or files whose names (not DAG id) match any of the patterns would be ignored (under the hood, re.findall() is used to match the pattern). Overall it works like a .gitignore file.
