ConfigMap volume is not mounting as volume along with secret - kubernetes

Question

I have references to both Secrets and ConfigMaps in my Deployment YAML file. The Secret volume is mounting as expected, but not the ConfigMap.
I created a ConfigMap with multiple files and when I do a kubectl get configmap ... it shows all of the expected values. Also, when I create just ConfigMaps it's mounting the volume fine, but not along with a Secret.
I have tried different scenarios of having both in same directory to separating them but dont seem to work.
Here is my YAML. Am I referencing the ConfigMap correctly?
apiVersion: apps/v1
kind: Deployment
metadata:
name: hello-deployment
spec:
selector:
matchLabels:
app: hello
replicas: 1 # tells deployment to run 1 pod
template:
metadata:
labels:
app: hello
spec:
containers:
- name: hello
image: XXX/yyy/image-50
ports:
- containerPort: 9009
protocol: TCP
volumeMounts:
- mountPath: /shared
name: configs-volume
readOnly: true
volumeMounts:
- mountPath: data/secrets
name: atp-secret
readOnly: true
volumes:
- name: configs-volume
configMap:
name: prompts-config
key: application.properties
volumes:
- name: atp-secret
secret:
defaultMode: 420
secretName: dev-secret
restartPolicy: Always
imagePullSecrets:
- name: ocirsecrets

Answer 1

You have two separate lists of volumes: and also two separate lists of volumeMounts:. When Kubernetes tries to find the list of volumes: in the Pod spec, it finds the last matching one in each set.
volumes:
- name: configs-volume
volumes: # this completely replaces the list of volumes
- name: atp-secret
In both cases you need a single volumes: or volumeMounts: key, and then multiple list items underneath those keys.
volumes:
- name: configs-volume
configMap: { ... }
- name: atp-secret # do not repeat volumes: key
secret: { ... }
containers:
- name: hello
volumeMounts:
- name: configs-volume
mountPath: /shared
- name: atp-secret # do not repeat volumeMounts: key
mounthPath: /data/secrets
