Nginx Ingress does not work after setting `externalTrafficPolicy: Local` #3733

Closed ghost closed 5 years ago

ghost commented 6 years ago

Is this a request for help?: No

Is this an ISSUE or FEATURE REQUEST? (choose one): Issue

What version of acs-engine?: 0.18.9

Orchestrator and version (e.g. Kubernetes, DC/OS, Swarm) Kubernetes 1.10.5

What happened: Installed nginx-ingress with helm chart. Trying to get sourceIP of client by setting externalTrafficPolicy: Local. Once set; all the routing stops. I cant hit the LoadBalancer IP to get the service. I get no response and http request times out. If I revert back to externalTrafficPolicy: Cluster it works fine.

I think it might be azure specific issue. However, it says in the docs that it should work on Azure.

Source: https://kubernetes.io/docs/tutorials/services/source-ip/#source-ip-for-services-with-type-loadbalancer

What you expected to happen: After setting externalTrafficPolicy: Local ; I should get client SourceIP and routing should work normally.

How to reproduce it (as minimally and precisely as possible):

  1. Install nginx-ingress
  2. Set externalTrafficPolicy: Local

Anything else we need to know: Its really a hit or miss; it worked on 1 of my clusters. Does not work on 2 others. Using Calico CNI AAD integration.
