kubernetes - Kubernetes Traefik Ingress收到错误的网关错误

Question

我已经在Kubernetes上为Traefik设置了以下Ingress和部署。我在实际域名上不断收到错误的网关错误。

由于某种原因，该服务无法正常工作，或者我的连接有误，或者选择器等出现问题。

apiVersion: v1
kind: Service
metadata:
  name: web
  labels:
    app: wordpress
spec:
  selector:
    k8s-app: traefik-ingress-lb
  ports:
    - name: http
      port: 80
      targetPort: 80
      protocol: TCP
  selector:
    app: wordpress

我的代码在下面，因此，如果有任何需要更正的建议，我们将不胜感激。

有几件事情要考虑:

我发现您在namsespace:中缺少metadata:。检查是否是这种情况。

尝试创建两个服务。一种用于wordpress，另一种用于treafik-ingress-lb。

您可能在ports:之后使用了太多空格。尝试这样的事情:

      ports:
      - name: http
        port: 80
        targetPort: 80
        protocol: TCP

检查标签配置是否正确。如果您需要更多有关它们的详细信息，请尝试this documentation。

请让我知道是否有帮助。
