具体来说，使用的ingress-controller不一样，有关的设置也不太一样 Kubernetes Ingress Controller （k8s官方）参考 http://github.com/kubernetes/ingress-nginx 官方文档地址：https://kubernetes.github.io/ingress-nginx/user-guide/nginx-configuration/annotations/?spm=5176.2020520152.0.0.74e016ddRLPYlr https://kubernetes.github.io/ingress-nginx/user-guide/miscellaneous/#websockets
https://github.com/kubernetes/ingress-nginx/blob/1614027cd42aa3fac53d62afc235b86adec7543d/docs/examples/multi-tls/README.md 在 nginx-ingress-controller 中默认已经支持websocket访问，官方文档中说明websocket不需要特别的配置，但需要在注解中配置以下三项 nginx.ingress.kubernetes.io/proxy-http-version: "1.1" nginx.ingress.kubernetes.io/proxy-read-timeout: "3600" nginx.ingress.kubernetes.io/proxy-send-timeout: "3600"网上看到的另一种写法配置 没实践过，若是配置的话，最好单独创建一个ingress规则yaml文件，别人其他的写在一起 地址：https://www.cnblogs.com/klvchen/articles/14874348.html 解决办法： annotations 加入 proxy_set_header Upgrade "websocket"; proxy_set_header Connection "Upgrade"; apiVersion: networking.k8s.io/v1beta1 kind: Ingress metadata: name: sx-data-server namespace: spot-standard annotations: kubernetes.io/ingress.class: "nginx" nginx.ingress.kubernetes.io/configuration-snippet: | proxy_set_header Upgrade "websocket"; proxy_set_header Connection "Upgrade"; spec: rules: - host: sx-data-server.internal.junengcloud.com http: paths: - path: / backend: serviceName: sx-data-server servicePort: 61051 NGINX Ingress Controller (nginx官方)http://github.com/nginxinc/kubernetes-ingress 文档地址：https://docs.nginx.com/nginx-ingress-controller/configuration/ingress-resources/advanced-configuration-with-annotations/ https://github.com/nginxinc/kubernetes-ingress/tree/v2.1.0/examples/websocket apiVersion: networking.k8s.io/v1 kind: Ingress metadata: name: cafe-ingress annotations: nginx.org/websocket-services: "ws-svc" # 具体的服务名 spec: rules: - host: cafe.example.com http: paths: - path: /tea pathType: Prefix backend: service: name: tea-svc port: number: 80 - path: /coffee pathType: Prefix backend: service: name: coffee-svc port: number: 80 - path: /ws pathType: Prefix backend: service: name: ws-svc port: number: 8008 |
