@kaxil Sure, here it is. I simplified my DAG, this version gives the same
error exactly. You'll need to add TEST_VAR to Airflow DB.
```python
"""Demo DAG"""
from datetime import timedelta
from airflow import DAG
from airflow.contrib.operators.kubernetes_pod_operator import
KubernetesPodOperator
from airflow.utils.dates import days_ago
args = {
'owner': 'airflow',
}
dag = DAG(
dag_id='demo_test',
default_args=args,
schedule_interval='0 0 * * *',
start_date=days_ago(2),
dagrun_timeout=timedelta(minutes=60),
tags=['demo'],
params={
"pod_op_image": "localhost:5000/my-image:latest",
"pod_op_image_pull_policy": "IfNotPresent",
},
)
env_params = {
"TEST_ENV_VAR": "TEST ENV VAR",
}
normal_op = KubernetesPodOperator(
dag=dag,
name='normal_op',
task_id='normal_op',
namespace='airflow',
image="{{ dag_run.conf['pod_op_image'] }}",
image_pull_policy="{{ dag_run.conf['pod_op_image_pull_policy'] }}",
env_vars=env_params,
cmds=["/bin/bash", "-c"],
arguments=["echo $TEST_ENV_VAR"],
)
#below is templated multi-string var which is used as argument further
templated_command = """
echo "{{ var.value.TEST_VAR}}"
echo "{{ params.my_param }}"
"""
templated_op = KubernetesPodOperator(
name='templated_op',
task_id='templated_op',
namespace='airflow',
image="{{ dag_run.conf['pod_op_image'] }}",
image_pull_policy="{{ dag_run.conf['pod_op_image_pull_policy'] }}",
cmds=["bash", "-c"],
arguments=[templated_command],
params={'my_param': 'Passed_Parameter'},
)
normal_op >> templated_op
if __name__ == "__main__":
dag.cli()
```
