如何在 minikube kubernetes 环境中保留弹性索引

Question

我是运行 elastic & kibana in kubernetes, minikube 本地环境。我想在 minikube 重新启动时保留弹性搜索索引。如果重新创建 minikube 虚拟机，保留索引并不重要。

如何更改配置，以便将搜索索引存储在 vm 或我的 macbook 主机上的永久磁盘中？

这是 Elastic Search 的现有配置文件。

apiVersion: apps/v1
kind: Deployment
metadata:
  name: elasticsearch
spec:
  selector:
    matchLabels:
      component: elasticsearch
  template:
    metadata:
      labels:
        component: elasticsearch
    spec:
      containers:
      - name: elasticsearch
        image: docker.elastic.co/elasticsearch/elasticsearch:6.2.1
        env:
        - name: discovery.type
          value: single-node
        ports:
        - containerPort: 9200
          name: http
          protocol: TCP

https://kubernetes.io/docs/concepts/storage/volumes

spec:
  containers:
  - name: elasticsearch
    # 8<-- snip -->8
    volumeMounts:
    - name: es-data
      mountPath: /var/lib/elasticsearch
  initContainers:
  - name: chown
    image: busybox:latest
    command:
    - chown
    - -R
    - "1000"  # or whatever your "elasticsearch" user-id is
    - /var/lib/elasticsearch
    volumeMounts:
    - name: es-data
      mountPath: /var/lib/elasticsearch
  volumes:
  - name: es-data
    hostPath:
      path: /some/path/in/minikube

initContainers 业务是因为 hostPath 将在 99% 的情况下被拥有 0:0 但 elasticsearch docker 图像是 USER elasticsearch（ uid 1000, IIRC)，因此无权 chown 卷挂载到容器中的目录。在启动 elasticsearch 之前，您需要运行 chown 命令，因此，initContainer.
