elasticsearch - 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。要访问Kibana仪表板，我创建了一个入口，该入口已映射到xyz.com。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，都会出现以下错误。为了使其正常工作，我的SERVER_BASEPATH应该是什么？我知道它默认为/ app / kibana。

我遵循了本指南https://github.com/pires/kubernetes-elasticsearch-cluster

知道可能是什么问题吗？

Answer 1

我相信官方kibana存储库中的example config可以提示出现此问题的原因，这是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不能以斜杠结尾的事实意味着，kibana会将您的设置解释为基本上以斜杠结尾。我还没有对此进行更深入的研究。

此错误消息很有趣:

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:不要以斜杠结尾并且不要以斜杠开头。这样的事情。

我使用您的部署 list 在minikube中重现了此内容，但最后删除了卷安装部分。将SERVER_BASEPATH更改为/<SOMETHING>效果很好，所以基本上我认为您只需要设置适当的基本路径即可。
