“Handling signal: ttou” message while running DAG in airflow

Question

I have created sample DAG, where I had DAG config as below.

default_args = {
    \'owner\': \'airflow\',         
    \'depends_on_past\': False, 
    \'start_da         


        

Answer 1

I don't really want to change worker_refresh_interval or worker_refresh_batch_size without a good reason. An alternative is to set an environment variable:

GUNICORN_CMD_ARGS="--log-level WARNING"

If setting this in a docker-compose.yml file, the following is tested with apache-airflow==1.10.6 with gunicorn==19.9.0:

environment:
    - 'GUNICORN_CMD_ARGS=--log-level WARNING'

If setting this in a Dockerfile, the following is tested with apache-airflow==1.10.6 with gunicorn==19.9.0:

ENV GUNICORN_CMD_ARGS --log-level WARNING
