zazaho opened a new issue, #26818:
URL: https://github.com/apache/airflow/issues/26818
### What do you see as an issue?
We are building a pipeline using airflow. We are using
KubernetesPodOperators and KubernetesExecutor. We are anticipating different
reasons that a task might fail. I would like to be able to explore how much
information I can get about the reason and the moment the task failed from the
context passed to he on_failure callback function. However, I find it
difficult to understand what will be passed in context. The only documentation
I have been able to find that relates to this is a page describing templated
variables. This seems not completely appropriate. Most of the variables
description is simply saying things like {{ ti }} task_instance object, which
is not enough for me to know what information I can get from inspecting these.
### Solving the problem
Perhaps there is better documentation that I missed, otherwise I believe
this is a documentation issue that would be relatively high on my priority list.
If documentation does exist, I think it should be made easier to find. If
not, I think a documentation chapter on the operator context and how to use it
(preferable with some concrete examples of usage) would be a huge gain for the
project, IMO.
