orientdb kubernetes 就绪探测错误：gzip：无效 header

Question

我正在尝试使用以下 yaml 文件在 kubernetes 集群上创建 orient db 部署，使用 orientdb:2.125 docker 来自 docker 中心的图像。

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: orientdb
  namespace: default
  labels:
    name: orientdb
spec:
  replicas: 2
  revisionHistoryLimit: 100
  strategy:
    type: RollingUpdate
    rollingUpdate:
      maxSurge: 1
      maxUnavailable: 1
  minReadySeconds: 5
  template:
    metadata:
      labels:
        service: orientdb
    spec:
      containers:
        # Custom pod name.
      - name: orientdb-node
        image: orientdb:2.1.25
        imagePullPolicy: Always
        ports:
        - name: http-port
          containerPort: 2480 # WEB port number.
        - name: binary-port
          containerPort: 2424
        livenessProbe:
          httpGet:
            path: /
            port: http-port
          initialDelaySeconds: 60
          timeoutSeconds: 30
        readinessProbe:
          httpGet:
            path: /
            port: http-port
          initialDelaySeconds: 5
          timeoutSeconds: 5

但我收到以下消息

Readiness probe errored: gzip: invalid header
Liveness probe errored: gzip: invalid header

如何修复 orient db 的就绪性和活性探测？

Answer 1

orientdb web 应用程序在端口 2480 returns 压缩 HTTP 响应，所以你应该添加自定义 HTTP 头来支持你的 httpGet livenessProbe 和 readinessProbe:

livenessProbe:
  httpGet:
    path: /
    port: http-port
    httpHeaders:
    - name: Accept-Encoding
      value: gzip
  initialDelaySeconds: 60
  timeoutSeconds: 30
readinessProbe:
  httpGet:
    path: /
    port: http-port
    httpHeaders:
    - name: Accept-Encoding
      value: gzip
  initialDelaySeconds: 5
  timeoutSeconds: 5
