NginxAlertreceiverConfigFailed

This alert is triggered when the configuration of NGINX ingress failed to reload.

NGINX Ingress Controller documentation here.

Troubleshooting hints

• Check that two NGINX ingress pods are present and running (replica=2):

  kubectl get  pod -n nginx-alertreceiver
  kubectl describe pod <nginx_pod_name> -n nginx-alertreceiver
  

• Check that the NGINX ingress is present and all the ressource events:

  kubectl get ingress -n nginx-alertreceiver
  kubectl describe ingress <nginx-ingress-name> -n nginx-alertreceiver
  

• Check the logs of the NGINX ingress pods.

• Check the NGINX configuration:

  kubectl exec -it -n  nginx-alertreceiver <nginx-ingress-pod-name> -- cat /etc/nginx/nginx.conf
  

  Solution

The solution will consist in identifying the NGINX ingress changes that are causing the issues and fix them in order to allow config reload to resume.
