我已完成 Sentry 的部署，但 kafka-controller 一直进入 CrashLoopBackOff 状态。

对于 kafka-controller

此外，为了公开 sentry-web，我可以查看 UI 并开始测试该工具 -

我为服务制作了这个 yaml

apiVersion: v1
kind: Service
metadata:
  name: sentry-web-service
  namespace: gopikab
spec:
  selector:
    app: sentry
    release: sentry
    role: web
  type: LoadBalancer
  ports:
    - protocol: TCP
      port: 80
      targetPort: 9000

但它仍然无法访问。我将 kafka 控制器副本数从 3 个减少到 1 个，以防止出现资源问题 - 但它们仍然不断死亡。
