Subject: Re: Flink reactive deployment on with kubernetes operator
Hi Enric,
You can try using persistent volume claim on your kubernetes cluster as a
JobResultStore, instead of using a local path from your underlying host, and
see if it works.
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: flink-data-pvc
spec:
resources:
requests:
storage: 10Gi
volumeMode: Filesystem
accessModes:
- ReadWriteOnce
And edit your yaml
(spec.podTemplate.spec.volumes.persistentVolumeClaim.claimName) to use this PVC:
apiVersion: flink.apache.org/v1beta1
kind: FlinkDeployment
metadata:
name: basic-reactive-example
spec:
image: flink:1.17
flinkVersion: v1_17
flinkConfiguration:
scheduler-mode: REACTIVE
taskmanager.numberOfTaskSlots: "2"
state.savepoints.dir: file:///flink-data/savepoints
state.checkpoints.dir: file:///flink-data/checkpoints
high-availability:
org.apache.flink.kubernetes.highavailability.KubernetesHaServicesFactory
high-availability.storageDir: file:///flink-data/ha
serviceAccount: flink
jobManager:
resource:
memory: "2048m"
cpu: 1
taskManager:
resource:
memory: "2048m"
cpu: 1
podTemplate:
spec:
containers:
- name: flink-main-container
volumeMounts:
- mountPath: /flink-data
name:
flink-volume
volumes:
- name: flink-volume
persistentVolumeClaim:
claimName: flink-data-pvc
job:
jarURI:
local:///opt/flink/examples/streaming/StateMachineExample.jar
parallelism: 2
upgradeMode: savepoint
state: running
savepointTriggerNonce: 0
mode: standalone
