pod具有未绑定的立即PersistentVolumeClaims ECK（Elasticsearch on Kubernetes）

Question

我正在尝试在本地minikube集群的kubernetes https://www.elastic.co/guide/en/cloud-on-k8s/current/index.html上部署弹性模块。我已经安装了操作员。

当我在下面应用Elasticsearch群集时，出现以下pod错误：

pod具有未绑定的立即PersistentVolumeClaims

以上错误表示没有persistentVolume可以绑定到PersistentVolumeClaim。默认情况下，local-storage不会真正动态创建persistentVolume。

要使用local-storage存储类的动态预配置机制，您需要配置local-storage类，以便它可以预配置persistentVolume。查看此讨论Kubernetes: What is the best practice for create dynamic local volume to auto assign PVs for PVCs?。

或者，不使用存储类的动态预配置机制，则需要使用persistentVolume创建一个hostPath，该PersistentVolumeClaim可以绑定到PersistentVolumeClaim。但这不是为生产使用推荐的解决方案。查看本指南here。

volumeClaimTemplates将基于弹性Yaml中的PersistentVolumeClaim自动创建。因此，您不应该创建一个 nodeSets。

由于PersistentVolumeClaim为2，因此创建了两个persistentVolume。因此，您需要创建两个apiVersion: v1 kind: PersistentVolume metadata: name: elasticsearch-data1 labels: type: local spec: storageClassName: standard capacity: storage: 10Gi accessModes: - ReadWriteOnce hostPath: path: "/mnt/data" --- apiVersion: v1 kind: PersistentVolume metadata: name: elasticsearch-data2 labels: type: local spec: storageClassName: standard capacity: storage: 10Gi accessModes: - ReadWriteOnce hostPath: path: "/mnt/data" 。

    function test(ids) {
        document.getElementById("myNav").style.width = "0%";
        var x = ids;
        //alert(ids + "---" + x)


        $.ajax({
            type: 'POST',
            url: '@Url.Action("ProductList1")',
            dataType: 'html',
            UpdateTargetId: 'loads',
            data: {
                Id: x,
            },
            success: function (status) {
                console.log('Send');
                $("#loads").html(status);
            },
            error: function () {
                console.log('something went wrong - debug it!');
            }
        });
    }
