Bringing up Nginx server with update its config and getting "default.conf is not a file or does not exist"

Question

I am trying to deploy an nginx server in Kubernetes. I am just trying to get a server up and look at it through a loadbalancer while also being able to modify the nginx config.

Using the below configuration I can not get the nginx webserver pod to start.

$ kubectl get pods
NAME                     READY   STATUS   RESTARTS   AGE
nginx-696c84fd7b-dr9hv   0/1     Error    3          55s

looking at the pod log I get the following:

$ kubectl logs nginx-696c84fd7b-dr9hv
/docker-entrypoint.sh: /docker-entrypoint.d/ is not empty, will attempt to perform configuration
/docker-entrypoint.sh: Looking for shell scripts in /docker-entrypoint.d/
/docker-entrypoint.sh: Launching /docker-entrypoint.d/10-listen-on-ipv6-by-default.sh
10-listen-on-ipv6-by-default.sh: /etc/nginx/conf.d/default.conf is not a file or does not exist, exiting
/docker-entrypoint.sh: Launching /docker-entrypoint.d/20-envsubst-on-templates.sh
/docker-entrypoint.sh: Configuration complete; ready for start up
2020/06/30 22:52:03 [emerg] 1#1: no "events" section in configuration
nginx: [emerg] no "events" section in configuration

I assume I am doing something wrong with the config. Do I need to change it to overwrite the or create the default.conf?

FYI - This is coming up in an AWS EKS cluster.

Here is the entire yaml I am launching using "kubectl create -f nginx_deployment.yaml":

apiVersion: v1
kind: ConfigMap
metadata:
  name: nginx-conf
data:
  nginx.conf: |
    http {
      server {
          location / {
              return 200 'Eureka!!';
              add_header Content-Type text/plain;
          }
      }
    }

spec:

I tried replacing ir to be default.conf but then it just hangs forever in the "ContainerCreaing" state.
