Skip ECSOperator Task in airflow - airflow

Question

I wanted to skip ECSOperator Task in airflow.
Basically I have two tasks:
CUSTOMER_CONFIGS = [
{
'customer_name': 'test',
'start_date': 17 # day of the month on which you want to trigger task
},
{
'customer_name': 'test',
'start_date': 18 # day of the month on which you want to trigger task
}
]
default_args = {
'depends_on_past': False,
'retries': 0
}
with DAG(
dag_id='run-ecs-task',
default_args=default_args,
start_date=days_ago(1),
schedule_interval='0 0 * * *',
max_active_runs=1,
) as dag:
current_day = datetime.now()
current_day = current_day.strftime("%d")
tasks = []
for config in CUSTOMER_CONFIGS:
task = ECSOperator(
task_id=f'{config.get("customer_name")}',
dag=dag,
retries=AIRFLOW_ECS_OPERATOR_RETRIES,
retry_delay=timedelta(seconds=10),
**ecs_operator_args
)
if config.get('start_date') != current_day:
task.state = State.SKIPPED
tasks.append(task)
How can I skip first ecs task on the bases of some condition.
Latern I would like to make these tasks in sequece

You didn't specify what is the condition but in general you can use ShortCircuitOperator. The ShortCircuitOperator is derived from the PythonOperator. It evaluates a condition and short-circuits the workflow if the condition is False.
from airflow.operators.python import ShortCircuitOperator
def condition():
if 1 > 2: # Replace with your condition
return True
return False
conditional_task = ShortCircuitOperator(
task_id='condition',
python_callable=func
)
task = ECSOperator(...)
task2 = ECSOperator(...)
conditional_task >> task
task2
