When using `podman play kube` with a YAML file that has pod labels,
apply those labels to the pods that podman makes.
For example, this Deployment spec has labels on a pod:
apiVersion: apps/v1
kind: Deployment
metadata:
name: myapp
labels:
app: myapp
spec:
selector:
matchLabels:
app: myapp
template:
metadata:
labels:
app: myapp
spec:
containers:
- name: web
image: nginx
ports:
- containerPort: 80
The pods that podman creates will have the label "app" set to "myapp" so
that these pods can be found with `podman pods ps --filter label=app`.
