无法访问 Kibana 仪表板

Question

我正在尝试在 AWS 上的 Kubernetes 集群中部署 Kibana。为了访问 Kibana 仪表板，我创建了一个映射到 xyz.com 的入口。这是我的 Kibana 部署文件。

apiVersion: apps/v1beta1
kind: Deployment
metadata:
  name: kibana
  labels:
    component: kibana
spec:
  replicas: 1
  selector:
    matchLabels:
     component: kibana
  template:
    metadata:
      labels:
        component: kibana
    spec:
      containers:
      - name: kibana
        image: docker.elastic.co/kibana/kibana-oss:6.3.2
        env:
        - name: CLUSTER_NAME
          value: myesdb
        - name: SERVER_BASEPATH
          value: /
        resources:
          limits:
            cpu: 1000m
          requests:
            cpu: 100m
        ports:
        - containerPort: 5601
          name: http
        readinessProbe:
          httpGet:
            path: /api/status
            port: http
          initialDelaySeconds: 20
          timeoutSeconds: 5
        volumeMounts:
          - name: config
            mountPath: /usr/share/kibana/config
            readOnly: true
      volumes:
        - name: config
          configMap:
            name: kibana-config

每当我部署它时，它都会给我以下错误。我的 SERVER_BASEPATH 应该是什么才能让它工作？我知道它默认为 /app/kibana。

我遵循了这个指南https://github.com/pires/kubernetes-elasticsearch-cluster

知道可能是什么问题吗？

我相信官方 kibana 存储库中的 example config 给出了有关此问题原因的提示，这里是 server.basePath 设置：

# Enables you to specify a path to mount Kibana at if you are running behind a proxy.
# Use the `server.rewriteBasePath` setting to tell Kibana if it should remove the basePath
# from requests it receives, and to prevent a deprecation warning at startup.
# This setting cannot end in a slash.
#server.basePath: ""

server.basePath 不能以斜线结尾的事实可能意味着 kibana 基本上将您的设置解释为以斜线结尾。不过，我还没有深入研究。

这个错误信息很有趣：

message: '"basePath" with value "/" fails to match the start with a slash, don\'t end with one pattern'

因此，此错误消息是对文档的补充：不要以斜线结尾，也不要以斜线开头。类似的东西。

我使用您的部署清单在minikube 中复制了此内容，但最后我删除了卷安装部分。将SERVER_BASEPATH 更改为/<SOMETHING> 工作正常，所以基本上我认为你只需要设置一个正确的基本路径。
