Confirming from the API Server logs, thank you @nicknezis for helping me get
to them, that the pod template loading is working from both the `ConfigMap` as
well as the default. I can also confirm that the kill switch is working as it
is supposed to.
The current issue is surrounding whether the custom Pod Templates are being
loaded. I am using the following Pod Template:
```yaml
apiVersion: v1
kind: PodTemplate
metadata:
name: pod-template-example
namespace: default
template:
metadata:
name: acking-pod-template-example
spec:
containers:
- name: executor
securityContext:
allowPrivilegeEscalation: false
```
and seeing the following on my laptop:
<details><summary>describe pod acking-0</summary>
```bash
Name: acking-0
Namespace: default
Priority: 0
