KR-Ravindra opened a new pull request, #76286:
URL: https://github.com/apache/airflow/pull/76286
We mount a hostPath volume whose path comes from a Dag param, and
KubernetesPodOperator sends the raw `{{ params.x }}` string to Kubernetes
instead of the rendered path.
### Problem
The nested template walk only renders `name`, `persistent_volume_claim` and
`config_map` on `V1Volume` and `name`/`sub_path` on `V1VolumeMount`, so
`V1HostPathVolumeSource.path` and `V1VolumeMount.mount_path` are never rendered.
### Fix
Add `host_path` to the `V1Volume` fields, render `path` on
`V1HostPathVolumeSource`, and add `mount_path` to `V1VolumeMount`, the same way
https://github.com/apache/airflow/pull/27719 added the existing ones.
### How tested
Extended `test_templates` in `test_pod.py`; it fails on main for both fields
and passes with this change.
