Odoo 14 长轮询总线在 GKE Ingress 后面运行的总线不可用

问题描述

我在 GKE 集群上运行了一个 odoo 14 应用。已通过设置 workers = 2 启用多处理器模式。我选择了默认的 GKE 入口将匹配 /longpolling/* 的请求路由到长轮询端口，其余的路由到普通端口。

这是我配置 GKE 入口的方法。

ingress.tf

resource "kubernetes_ingress" "ingress_service" {
  Metadata {
    name = "ingress-service"
    annotations = {
      "networking.gke.io/managed-certificates": "subdomain-company-com"
      "networking.gke.io/v1beta1.FrontendConfig": "frontend-config" # for https redirection
    }
  }
  spec {
    rule {
      host = "dev.company.com"
      http {
        path {
          path = "/*"
          backend {
            service_name = kubernetes_service.core_service.Metadata.0.name
            service_port = kubernetes_service.core_service.spec.0.port.0.port
          }
        }
      }
    }

    rule {
      host = "dev.company.com"
      http {
        path {
          path = "/longpolling/*"
          backend {
            service_name = kubernetes_service.core_service.Metadata.0.name
            service_port = kubernetes_service.core_service.spec.0.port.1.port
          }
        }
      }
    }
  }

  wait_for_load_balancer = true
}

Kubernetes 服务如下所示。

resource "kubernetes_service" "core_service" {
  Metadata {
    name = "core-service"
    annotations = {
      "cloud.google.com/backend-config" = jsonencode({
        "ports" = {
          "longpolling" = "long-polling-be-config"
        }
      })
    }
  }
  spec {
    type = "NodePort"
    selector = {
      app = "core"
    }
    port {
      name = "normal"
      port = 8080
      protocol = "TCP"
      target_port = "8069"
    }
    port {
      name = "longpolling"
      port = 8081
      protocol = "TCP"
      target_port = "8072"
    }
  }
}

自定义后端配置 long-polling-be-config 如下。

apiVersion: cloud.google.com/v1
kind: BackendConfig
Metadata:
  name: long-polling-be-config
spec:
  healthCheck:
    checkIntervalSec: 30
    healthyThreshold: 5
    type: HTTP
    requestPath: /web/database/selector
    port: 8081

端口 8069 的运行状况检查在 Kubernetes Deployment 中定义如下。

          readiness_probe {
            http_get {
              path = "/web/database/selector"
              port = "8069"
            }
            initial_delay_seconds = 15
            period_seconds = 30
          }

后端运行良好，但我仍然每分钟左右看到一次此错误。

Exception

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/odoo/http.py",line 639,in _handle_exception
    return super(JsonRequest,self)._handle_exception(exception)

Exception: bus.Bus unavailable

我遵循了 question 中的解决方案，这是通过 Nginx 反向代理。我如何使用 GKE 入口复制它？
