Redis – Pod Launching failed: Pod took too long to start, Failed to run KubernetesPodOperator secret

I’m running the quickstart for KubernetesPodOperator secret using the link below : https://cloud.google.com/composer/docs/how-to/using/using-kubernetes-pod-operator

Code used below :

from airflow import models
from airflow.contrib.kubernetes import secret
from airflow.contrib.operators import kubernetes_pod_operator

# A Secret is an object that contains a small amount of sensitive data such as
# a password, a token, or a key. Such information might otherwise be put in a
# Pod specification or in an image; putting it in a Secret object allows for
# more control over how it is used, and reduces the risk of accidental
# exposure.

secret_env = secret.Secret(
    # Expose the secret as environment variable.
    deploy_type='env',
    # The name of the environment variable, since deploy_type is `env` rather
    # than `volume`.
    deploy_target='SQL_CONN',
    # Name of the Kubernetes Secret
    secret='airflow-secrets',
    # Key of a secret stored in this Secret object
    key='sql_alchemy_conn')
secret_volume = secret.Secret(
    'volume',
    # Path where we mount the secret as volume
    '/var/secrets/google',
    # Name of Kubernetes Secret
    'service-account',
    # Key in the form of service account file name
    'service-account.json')

YESTERDAY = datetime.datetime.now() - datetime.timedelta(days=1)

# If a Pod fails to launch, or has an error occur in the container, Airflow
# will show the task as failed, as well as contain all of the task logs
# required to debug.
with models.DAG(
        dag_id='composer_sample_kubernetes_pod',
        schedule_interval=datetime.timedelta(days=1),
        start_date=YESTERDAY) as dag:
    # Only name, namespace, image, and task_id are required to create a
    # KubernetesPodOperator. In Cloud Composer, currently the operator defaults
    # to using the config file found at `/home/airflow/composer_kube_config if
    # no `config_file` parameter is specified. By default it will contain the
    # credentials for Cloud Composer's Google Kubernetes Engine cluster that is
    # created upon environment creation.
  kubernetes_secret_vars_ex = kubernetes_pod_operator.KubernetesPodOperator(
        task_id='ex-kube-secrets',
        name='ex-kube-secrets',
        namespace='default',
        image='python:3.6-stretch',
        cmds=["python","-c"],
        arguments=["print('hello world')"],
        labels={"foo": "bar"},
        startup_timeout_seconds=300,
        # The secrets to pass to Pod, the Pod will fail to create if the
        # secrets you specify in a Secret object do not exist in Kubernetes.
        secrets=[secret_env, secret_volume],
        # env_vars allows you to specify environment variables for your
        # container to use. env_vars is templated.
        env_vars={
            'EXAMPLE_VAR': '/example/value',
            'GOOGLE_APPLICATION_CREDENTIALS': '/var/secrets/google/service-account.json'})

I have created successfully the secret using :

kubectl create secret generic airflow-secrets 
--from-literal sql_alchemy_conn=test_value

I am receiving this error :
