无法接收有关任务失败的电子邮件，甚至无法使用EmailOperator

嗨，

即使添加必需的参数以发送邮件，我也无法从我的邮箱接收电子邮件。

下面是我的默认参数的样子-

default_args = {
    'owner': 'phonrao',
    'depends_on_past': False,
    #'start_date': datetime(2019, 3, 28),
    'start_date': airflow.utils.dates.days_ago(2),
    'email': ['phonrao@gmail.com'],
    'email_on_failure': True,
    'email_on_retry': True,
    'retries': 1,
    'retry_delay': timedelta(minutes=5),
    #'on_failure_callback': report_failure,
    #'end_date': datetime(2020,4 ,1),
    #'schedule_interval': '@hourly',
}

我之间没有几个HttpsOperator任务-这些任务运行良好并且成功，但是它们不会在出现错误时发送电子邮件（我故意尝试引入错误来检查是否发送了电子邮件）。以下是我的任务示例。

t1 = SimpleHttpOperator(
                   task_id='t1',
                   http_conn_id='http_waterfall',
                   endpoint='/update_data',
                   method='POST',
                   headers={"Content-Type":"application/json"},
                                   xcom_push=True,
                                   log_response=True,
                   dag=dag,
)

这是我的EmailOperator任务

t2 = EmailOperator(
              dag=dag,
                  task_id="send_email",
                  to='phonrao@gmail.com',
                          subject='Success',
                      html_content="<h3>Success</h3>" 
)

t2 >> t1

以下是日志中的错误：

下面是我的airflow.cfg

 [email]
email_backend = airflow.utils.email.send_email_smtp

[smtp]
# If you want airflow to send emails on retries, failure, and you want to use
# the airflow.utils.email.send_email_smtp function, you have to configure an
# smtp server here
smtp_host = localhost
smtp_starttls = True
smtp_ssl = False
# Uncomment and set the user/pass settings if you want to use SMTP AUTH
# smtp_user = airflow
# smtp_password = airflow
smtp_port = 25
smtp_mail_from = airflow@example.com

有人遇到这个问题吗？对如何解决这个问题有什么建议吗？

如果气流在Kubernetes上运行（通过舵图安装），则应查看“ airflow-worker-0”窗格，并确保配置中的SMTP_HOST或SMTP_USER ...环境变量可用。只需调试，即可访问airflow-worker的容器，然后运行python，然后尝试使用这些命令以确保其正常工作。

import airflow 
airflow.utils.email.send_email('example@gmail.com', 'Airflow TEST HERE', 'This is airflow status success')

通过解决SMTP的环境变量，我遇到了相同的问题。现在可以了。
