Kubernetes中的TCP入口支持 [英] TCP ingress support in Kubernetes

推荐答案

nginx入口(和 Ingress 资源是第7层设施，不支持第4层，无论如何，将来可能会支持第4层.请注意， nginx本身支持第4层流量，而不是K8s Ingress.

The nginx-ingress (and the Ingress resource in K8s for that matter) is a layer 7 facility and doesn't support layer 4, in any case, layer 4 might be supported at some point in the future. Note that nginx itself supports layer 4 traffic but not the K8s Ingress.

如果您想直接终止TCP或UDP，则可以使用标准的 Kubernetes服务. NodePort 和

If you like to directly terminate TCP or UDP you can use standard Kubernetes services. NodePort and LoadBalancer (depending on the cloud provider) types of services should also support TCP/UDP.

这里有一个有关如何通过nginx入口(来自NGINX公司)支持TCP/UDP的教程

There's a tutorial on how to support TCP/UDP with an nginx ingress (from the NGINX company) here.
