AKS - How to mount volume with file for pod/image - docker

Question

I am kind of new to AKS deployment with volume mount. I want to create a pod in AKS with image; that image needs a volume mount with config.yaml file (that I already have and needs to be passed to that image to run successfully).
Below is the docker command that is working on local machine.
docker run -v <Absolute_path_of_config.yaml>:/config.yaml image:tag
I want to achieve same thing in AKS. When I tried to deploy same using Azure File Mount (with PersistentVolumeClaim) volume is getting attached. The question now is how to pass config.yaml file to that pod. I tried uploading config.yaml file to Azure File Share Volume that is attached in POD deployment without any success.
Below is the pod deployment file that I used
kind: Pod
apiVersion: v1
metadata:
name: mypod
spec:
containers:
- name: mypod
image: image:tag
resources:
requests:
cpu: 100m
memory: 128Mi
limits:
cpu: 250m
memory: 1Gi
volumeMounts:
- mountPath: "/config.yaml"
name: volume
volumes:
- name: volume
persistentVolumeClaim:
claimName: my-azurefile-storage
Need help regarding how I can use that local config.yaml file for aks deployment so image can run properly.
Thanks in advance.

Create a kubernetes secret using config.yaml file.
kubectl create secret generic config-yaml --from-file=config.yaml
Mount it as a volume in the pod.
apiVersion: v1
kind: Pod
metadata:
name: config
spec:
containers:
- name: config
image: alpine
command:
- cat
resources: {}
tty: true
volumeMounts:
- name: config
mountPath: /config.yaml
subPath: config.yaml
volumes:
- name: config
secret:
secretName: config-yaml
Exec to the pod and view the file.
kubectl exec -it config sh
kubectl exec [POD] [COMMAND] is DEPRECATED and will be removed in a future version. Use kubectl exec [POD] -- [COMMAND] instead.
/ # ls
bin dev home media opt root sbin sys usr
config.yaml etc lib mnt proc run srv tmp var
/ # cat config.yaml
