> While trying to add Pod annotation through pod template in FlinkDeployment, taskmanager was keep crashing.
> Pod template that I used:
> {code:java}
>   taskManager:
>     podTemplate:
>       apiVersion: v1
>       kind: Pod
>       metadata:
>         annotations:
>           iam.amazonaws.com/role: fake-role-arn
> {code}
> It created below ConfigMap and mounted to the deployment:
> {code:java}
> apiVersion: v1
> data:
>   taskmanager-pod-template.yaml: |
>     ---
>     apiVersion: "v1"
>     kind: "Pod"
>     metadata:
>       annotations:
>         iam.amazonaws.com/role: "fake-role-arn"
> kind: ConfigMap
> {code}
> Looks like missing "spec" stanza in pod template resulted in the crash and I couldn't find any documentation that "spec" is required for pod template even for just adding metadata annotations.
> Adding below worked fine
> {code:java}
>   taskManager:
>     podTemplate:
>       apiVersion: v1
>       kind: Pod
>       metadata:
>         annotations:
>           iam.amazonaws.com/role: fake-role-arn
>       spec: {}
> {code}
> Corresponding ConfigMap
> {code:java}
> apiVersion: v1
> data:
>   taskmanager-pod-template.yaml: |
>     ---
>     apiVersion: "v1"
>     kind: "Pod"
>     metadata:
>       annotations:
>         iam.amazonaws.com/role: "fake-role-arn"
>     spec:
>       containers: []
> {code}
