I am able to access my django app deployment using LoadBalancer service type but I'm trying to switch to ClusterIP service type and ingress-nginx but I am getting 503 Service Temporarily Unavailable when I try to access the site via the host url. Describing the ingress also shows error: endpoints "django-service" not found
and error: endpoints "default-http-backend" not found
. What am I doing wrong?
This is my service and ingress yaml:
