Simple POC cluster failing to provision - 'default backend - 404'

Summary

I'm attempting to do a POC, and with a base configuration all I get is a page that says "default backend - 404"

Steps to reproduce

  • Create an eks k8s cluster in AWS

  • Install stand-alone cert-manager into the namespace 'cert-manager'

  • Install metrics server into the namespace 'kube-system'

  • Install external-dns into the namespace 'external-dns'

  • Create the namespace 'gitlab-system'

  • kubectl apply the yamls for the certifiates

  • helm template gitlab gitlab/gitlab -f values.yaml > gitlab_chart.yaml

  • kubectl apply -f gitlab_chart.yaml

Configuration used

(Please provide a sanitized version of the configuration used wrapped in a code block (```yaml))

contents of values.yaml

global:
  hosts:
    domain: <my.domain (a valid domain)>
    https: true
  ingress:
    configureCertmanager: false
    tls:
      enabled: true
      secretName: <secret for certificate - created via Cert-Manager / LetsEncrypt - publicly valid>
nginx-ingress:
  controller:
    config:
      use-forwarded-headers: "true" 
    service:
      annotations:
        service.beta.kubernetes.io/aws-load-balancer-backend-protocol: https
        service.beta.kubernetes.io/aws-load-balancer-connection-idle-timeout: "3600"
        service.beta.kubernetes.io/aws-load-balancer-ssl-cert: <the ARN>
        service.beta.kubernetes.io/aws-load-balancer-ssl-ports: https
        external-dns.alpha.kubernetes.io/hostname: "gitlab.<my.domain>,registry.<my.domain>,minio.<my.domain>"
certmanager:
  install: false
certmanager-issuer:
  email: me@example.com
  install: false

Current behavior

I browse to gitlab.<my.domain>, and I get the message "default backend - 404"

Expected behavior

I browse to gitlab.<my.domain>, and I get a login page
