Custom Upstream server checks¶
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: http-svc annotations: nginx.ingress.kubernetes.io/upstream-fail-timeout: "30" spec: rules: - host: foo.bar.com http: paths: - path: / backend: serviceName: http-svc servicePort: 80 " | kubectl create -f -
Check the annotation is present in the Ingress rule:
kubectl get ingress http-svc -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-http-svc-x-80 { least_conn; server 10.2.92.2:8080 max_fails=5 fail_timeout=30; } ....
