"0/1 nodes are available: pod has unbound immediate PersistentVolumeClaims" error using microk8s


by using the helm chart of emqx operator(https://github.com/emqx/emqx-operator) and going to follow their guide (https://github.com/emqx/emqx-operator/blob/main/docs/en_US/tasks/configure-emqx-persistence.md) on how to set data persistence I get the error given in the following question.

I did exactly as described in the guide, but precisely I get the error reported in relation to emqx-core.

Moreover, By doing:

kubectl get sc

I get the following output:

NAME    PROVISIONER    RECLAIMPOLICY    VOLUMEBINDINGMODE    ALLOWVOLUMEEXPANSION
microk8s-hostpath (default)   microk8s.io/hostpath   Delete   WaitForFirstConsumer   false

Note: I use the APIVersion apps.emqx.io/v2alpha1


Solution

  • apiVersion: apps.emqx.io/v2alpha1
    kind: EMQX
    metadata:
      name: emqx
    spec:
      image: emqx:5.0
      coreTemplate:
        spec:
          volumeClaimTemplates:
            storageClassName: microk8s-hostpath
            resources:
              requests:
                storage: 20Mi
            accessModes:
            - ReadWriteOnce
          replicas: 3
    

    You can try the above yaml configuration.
