ingress-nginx-helm/controllers/nginx/examples/custom-upstream-check/README.md

This example shows how is possible to create a custom configuration for a particular upstream associated with an Ingress rule.

echo " apiVersion: extensions/v1beta1 kind: Ingress metadata: name: echoheaders annotations: ingress-nginx.kubernetes.io/upstream-fail-timeout: "30" spec: rules:

• host: foo.bar.com http: paths:
  • path: / backend: serviceName: echoheaders servicePort: 80 " | kubectl create -f -

Check the annotation is present in the Ingress rule:

kubectl get ingress echoheaders -o yaml
``

Check the NGINX configuration is updated using kubectl or the status page:

$ kubectl exec nginx-ingress-controller-v1ppm cat /etc/nginx/nginx.conf

.... upstream default-echoheaders-x-80 { least_conn; server 10.2.92.2:8080 max_fails=5 fail_timeout=30;

}

....
