nginx ingress seems not working with server

[huytn1219]

Hi,

I have been struggling to figure out how to get Nginx Ingress working with Argo Workflow. I'm able to set up ArgoCD and Argo Event with Nginx Ingress in GKE but I'm hitting the wall with Argo Workflow.

Here is my Argo Workflow Ingress configuration:

apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
  name: argo-workflow-ingress
  namespace: argo
  annotations:
     nginx.ingress.kubernetes.io/backend-protocol: "HTTPS"
spec:
  ingressClassName: nginx
  tls:
  - hosts:
    - xxx.xxx.xxx.io
    secretName: argo-workflow-tls
  rules:
  - host: xxx.xxx.xxx.io
    http:
      paths:
      - backend:
          serviceName: argo-server
          servicePort: 2746
        path: /

And this is part of my Argo Workflow deployment:

    spec:
      containers:
      - args:
        - server
        - --namespaced
        - --auth-mode
        - server
        - --auth-mode
        - client
        image: argoproj/argocli:v3.0.2
        imagePullPolicy: IfNotPresent
        name: argo-server
        ports:
        - containerPort: 2746
          name: web
          protocol: TCP

I can port-forward Argo Workflow to my local and access the service with https://localhost:2746.
However, when I applied the Ingress and tried to access it from the browser, I hit 502 Bad Gateway.
Here is my Nginx Ingress log

failed (104: Connection reset by peer) while reading response header from upstream, client: xx.xx.xx.xx, server: xxx.xxx.xxx.io, request: "GET / HTTP/1.1", upstream: "http://172.20.0.107:2746/", host: "xxx.xxx.xxxx.io"

Am I missing anything?

You can use helm chart to install argo-workflows instead quick-start-miniaml.yaml manifest.

Based on the resources listed here, you're missing a Service resource for your Ingress to connect to
