I have app-1 pods created by StatefulSet and in that, I am creating PVC as well
apiVersion: apps/v1
kind: StatefulSet
metadata:
name: app-1
spec:
replicas: 3
selector:
matchLabels:
app: app-1
serviceName: "app-1"
template:
metadata:
labels:
app: app-1
spec:
containers:
- name: app-1
image: registry.k8s.io/nginx-slim:0.8
resources:
requests:
cpu: 100m
memory: 128Mi
limits:
cpu: 250m
memory: 256Mi
ports:
- containerPort: 4567
volumeMounts:
- name: app-1-state-volume-claim
mountPath: /app1Data
- name: app-2-data-volume-claim
mountPath: /app2Data
volumeClaimTemplates:
- metadata:
name: app-1-state-volume-claim
spec:
accessModes: [ "ReadWriteOnce" ]
storageClassName: "managed-csi-premium"
resources:
requests:
storage: 1Gi
- metadata:
name: app-2-data-volume-claim
spec:
accessModes: [ "ReadWriteOnce" ]
storageClassName: "managed-csi-premium"
resources:
requests:
storage: 1Gi
state of the app1 is maintained in PVC - app-1-state-volume-claim
app1 is also creating data for app2 in PVC - app-2-data-volume-claim
I want to access app-2-data-volume-claim in another pod deployment described below
apiVersion: apps/v1
kind: DaemonSet
metadata:
name: app-2
spec:
selector:
matchLabels:
name: app-2
template:
metadata:
labels:
name: app-2
spec:
containers:
- name: app-2
image: quay.io/fluentd_elasticsearch/fluentd:v2.5.2
resources:
limits:
memory: 200Mi
requests:
cpu: 100m
memory: 200Mi
volumeMounts:
- name: app2Data
mountPath: /app2Data
volumes:
- name: app2Data
persistentVolumeClaim:
claimName: app-2-data-volume-claim
This is failing with below output
persistentvolumeclaim "app-2-data-volume-claim" not found
How can I do that?
I cannot use Azure file share due to app-1 limitation.
