Good day everyone! Everything is done on Kubernetes on AWS (EKS)
I am trying to run nginx proxy in a container that will be thrown onto an internal service. The scheme is as follows:
alb ingress controller -> service nginx -> nginx pod -> my service -> myservice pod
Error in error.log nginx pod:
2019/04/10 06:07:31 [error] 6#6: *116 connect() failed (111: Connection refused) while connecting to upstream, client: 172.31.43.108, server: myservice.host.com, request: "GET / HTTP/1.1", upstream: "http://172.31.9.18:80/", host: "172.31.8.88" So, everything works: alb ingress controller -> my service -> myservice pod
INGRESS did here for this article, it works fine: https://kubernetes-sigs.imtqy.com/aws-alb-ingress-controller/guide/walkthrough/echoserver/
My configs:
