Angular 如何解决运行Kubernetes群集时nginx上的502坏网关错误

我已经用一些后端微服务建立了一个Kubernetes集群，它们都可以很好地与nginx配合使用。但是，我无法访问我的角度前端，因为它给我一个502错误

我的angular应用程序的Dockerfile（我尝试了许多不同的实现，这是最近的一个）：

angular应用程序的my Kubernetes部署和服务的yaml文件：

apiVersion: apps/v1
kind: Deployment
metadata:
  name: client-depl
spec:
  replicas: 1
  selector:
    matchLabels:
      app: frontendx
  template:
    metadata:
      labels:
        app: frontendx
    spec:
      containers:
        - name: frontendx
          image: akeedm/frontendx

---

apiVersion: v1
kind: Service
metadata:
  name: client-srv
spec:
  selector:
    app: frontendx
  type: ClusterIP
  ports:
    - name: frontendx
      protocol: TCP
      port: 4200
      targetPort: 4200

我的入口配置的yaml文件（最后一个路由是问题）：

应用yaml文件并部署kubernetes群集后，我可以正确连接到除angular应用程序之外的所有服务。当我尝试连接到时，出现错误502坏网关。当我尝试在/var/log/nginx查看日志时，access.log和error.log文件都是空的

下面是angular应用程序的running pod启动时的终端。当我得到502错误时，没有新条目

/docker-entrypoint.sh:/docker-entrypoint.d/不为空，将 尝试执行配置

/docker-entrypoint.sh：在中查找shell脚本 /docker入口点/

/docker-entrypoint.sh:启动 /docker-entrypoint.d/10-listen-on-ipv6-by-default.sh

10-listen-on-ipv6-by-default.sh:info:获取 /etc/nginx/conf.d/default.conf

10-listen-on-ipv6-by-default.sh:info:Enabled-listen-on-ipv6-in /etc/nginx/conf.d/default.conf

/docker-entrypoint.sh:启动 /docker-entrypoint.d/20-envsubs-on-templates.sh

/docker-entrypoint.sh:启动 /docker-entrypoint.d/30-tune-worker-processs.sh

/docker-entrypoint.sh：配置完成；准备好启动了吗

您是否尝试过单独运行FE容器（例如在docker中），以查看其是否有效？了解问题所在。另外，请运行

kubectl描述入口srv
