NginxInc/kubernetes-ingress - 打开 portainer websocket 连接 - 传递 headers

Question

在此处报告解决方案以供将来参考，因为我在实施此解决方案时找不到任何单一资源：

使用 nginxinc/kubernetes-ingress controller not the kubernetes/ingress-nginx.

问题始于 portainer v2.1.1，但如果您需要创建入口规则并通过 headers，或应用任何特定规则。

问题代码：

Unable to upgrade the connection (err=websocket: the client is not using the websocket protocol: 'upgrade' token not found in 'Connection' header) (code=500)

WebSocket connection to 'ws://portainer.example.com/.....// failed

Answer 1

关注 Nginx websocket proxying guide 使用 Nginx snippets:

的最小解决方案

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: portainer-ingress
  namespace: portainer
  annotations:
    nginx.org/location-snippets: |
      proxy_set_header   Upgrade            $http_upgrade;
      proxy_set_header   Connection         "upgrade";
    
spec:
  ingressClassName: nginx
  rules:
    -  host: portainer.example.com
       http:
        paths:
          - path: /
            backend:
              service:
                name: portainer
                port:
                  number: 9000
            pathType: Prefix

运行 Nginx ingress controller version v1.10.1 installed using manifests

helm.sh/chart: ingress-nginx-3.23.0
app.kubernetes.io/name: ingress-nginx
app.kubernetes.io/instance: ingress-nginx
app.kubernetes.io/version: 0.44.0
