You can configure the email that is being sent in your airflow.cfg
by setting a subject_template
and/or a html_content_template
in the email
section.
[email] email_backend = airflow.utils.email.send_email_smtp subject_template = /path/to/my_subject_template_file html_content_template = /path/to/my_html_content_template_file
To access the task's information you use Jinja Templating in your template files.
For example a html_content_template
file could look like this:
Try {{try_number}} out of {{max_tries + 1}}<br> Exception:<br>{{exception_html}}<br> Log: <a href="{{ti.log_url}}">Link</a><br> Host: {{ti.hostname}}<br> Log file: {{ti.log_filepath}}<br> Mark success: <a href="{{ti.mark_success_url}}">Link</a><br>
Note
