Setting up Ingress (Kubernetes)

0 votes

I’m trying to set up an ingress which routes traffic to my underlying services. But I end up getting an error when I deploy my ingress-controller-deploymnet.yaml file. The pod with the ingress-controller crashes immediately with error message “CrashLoopBackOff”

Pod description:

The issue is the args. Try setting your args in the following manner:

      args:

        - /nginx-ingress-controller
        - --default-backend-service=$(POD_NAMESPACE)/default-http-backend
        - --configmap=$(POD_NAMESPACE)/nginx-configuration
        - --tcp-services-configmap=$(POD_NAMESPACE)/tcp-services
        - --udp-services-configmap=$(POD_NAMESPACE)/udp-services
        - --publish-service=$(POD_NAMESPACE)/ingress-nginx
        - --annotations-prefix=nginx.ingress.kubernetes.io
