Apache AirFlow : How to schedule it on remote machines - airflow

Question

I am new to apache airflow, Could you please help me to understand where/what should I configure to run a DAG in a remote machines. I am using the celery_executor to execute the code on worker nodes, I have not done any configurations on worker nodes, I am using RabitMQ as queue service and seems like I have configured the Airflow cluster correctly.
My DAG file :
"""
Code that goes along with the Airflow tutorial located at:
https://github.com/apache/airflow/blob/master/airflow/example_dags/tutorial.py
"""
from airflow import DAG
from airflow.operators.bash_operator import BashOperator
from datetime import datetime, timedelta
default_args = {
'owner': 'Airflow',
'depends_on_past': False,
'start_date': datetime(2015, 6, 1),
'email': ['airflow#example.com'],
'email_on_failure': False,
'email_on_retry': False,
'retries': 1,
'retry_delay': timedelta(minutes=5),
# 'queue': 'bash_queue',
# 'pool': 'backfill',
# 'priority_weight': 10,
# 'end_date': datetime(2016, 1, 1),
}
dag = DAG('sample_date_print', schedule_interval='*/1 * * * *', default_args=default_args)
# t1, t2 and t3 are examples of tasks created by instantiating operators
t1 = BashOperator(
task_id='print_date',
bash_command='date',
dag=dag)
t2 = BashOperator(
task_id='sleep',
bash_command='sleep 5',
retries=3,
dag=dag)
templated_command = """
{% for i in range(5) %}
echo "{{ ds }}"
echo "{{ macros.ds_add(ds, 7)}}"
echo "{{ params.my_param }}"
{% endfor %}
"""
t3 = BashOperator(
task_id='templated',
bash_command=templated_command,
params={'my_param': 'Parameter I passed in'},
dag=dag)
t2.set_upstream(t1)
t3.set_upstream(t1)
The logs:
{
"host_name": "1f176162bc5e",
"full_command": "['/usr/local/bin/airflow', 'tasks', 'run', 'sample_date_print', 'print_date', '2015-06-04T00:00:00+00:00', '--local', '--pool', 'default_pool', '-sd', '/root/airflow/dags/sample_date_print.py']"
}
I am not sure how should I change the default behavior of --local in a way that DAG file
go and execute on remote machines, please help me

Have you changed the executor = SequentialExecutor to executor = CeleryExecutor in your airflow.cfg? I think you have not or if you have you forgot to mention it.
It's the firs thing to change if you want to change execution mode.
Other things you might've missed with configurations could be mentioned here or here.
