ide chart : cannot working backend sts with sqlite

[suminhong]

Hi, I'm simply trying to install this langflow-ide chart on my company's Kubernetes.

I used the value file below.

langflow:
  backend:
    replicaCount: 1
    service:
      type: ClusterIP
      port: 7860
    backendOnly: true
    numWorkers: 1
    image:
      tag: v1.1.1
    sqlite:
      enabled: true
      volume:
        size: "10Gi"
        existingStorageClassName: "gp3"
    env:
      - name: LANGFLOW_PORT
        value: "7860"
  
  frontend:
    enabled: true
    replicaCount: 1
    service:
      type: ClusterIP
      port: 8080
    image:
      tag: v1.1.1

But the following error occurs.

I am also facing the same when i try to deploy this on AKS. Kindly help

Hi @suminhong / @dkpvw take a look at this comment in the values.yaml, could be the existingStorageClassName you are using.

@elolivier
Hi. It's true that I want to use an already existing storage class. What's the problem with this?

[elolivier-nxp]

@suminhong There is no problem (or at least it shouldn't) just that I think you need to provide the storageClass configuration since you're not using default one. This storage class determines how k8s provisions the underlying storage for SQLite.
