我试图通过传入不起作用的 Bash 行 (thisshouldnotrun
) 来故意使 Airflow 任务失败并出错。 Airflow 正在输出以下内容:

Airflow 会针对此类错误发送电子邮件吗?如果没有,针对这些错误发送电子邮件的最佳方式是什么?
我什至不确定 airflow.cfg
是否设置正确...由于最终目标是测试电子邮件警报通知,我想确保 airflow.cfg 设置正确。这是设置:
[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 = emailsmtpserver.region.amazonaws.com
smtp_starttls = True
smtp_ssl = False
# Uncomment and set the user/pass settings if you want to use SMTP AUTH
# smtp_user = airflow_data_user
# smtp_password = password
smtp_port = 587
smtp_mail_from = airflow_data_user@domain.com
什么是smtp_starttls
?我在文档或网上找不到任何信息。如果我们需要双因素身份验证才能查看电子邮件,这对 Airflow 来说会是一个问题吗?
这是我的 Bash 命令:
task1_bash_command = """
export PATH=/home/ubuntu/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin
export rundate=`TZ='America/Los_Angeles' date +%F -d "yesterday"`
export AWS_CONFIG_FILE="/home/ubuntu/.aws/config"
/home/ubuntu/bin/snowsql -f //home/ubuntu/sql/script.sql 1> /home/ubuntu/logs/"$rundate"_dev.log 2> /home/ubuntu/logs/"$rundate"_error_dev.log
if [ -e /home/ubuntu/logs/"$rundate"_error_dev.log ]
then
exit 64
fi
我的任务:
task1 = BashOperator(
task_id = 'run_bash',
bash_command = task1_bash_command,
dag = dag,
retries = 2,
email_on_failure = True,
email = 'username@domain.com')
最佳答案
smtp_starttls
基本上意味着使用 TLS
如果您想改用 SSL,请将其设置为 False
并将 smtp_ssl
设置为 True
。您可能需要 smtp_user
和 smtp_password
。
Airflow 不会处理两步验证。但是,如果您使用的是 AWS,您可能不需要它,因为您的 SMTP (SES) 凭证与您的 AWS 凭证不同。
参见 here .
编辑:
为了让 Airflow 在失败时发送电子邮件,需要在您的任务中设置几件事,email_on_failure
和 email
。
例子见这里:
def throw_error(**context):
raise ValueError('Intentionally throwing an error to send an email.')
t1 = PythonOperator(task_id='throw_error_and_email',
python_callable=throw_error,
provide_context=True,
email_on_failure=True,
email='your.email@whatever.com',
dag=dag)
