Kong ingress controller with CP and postgres?

Questions
1

Hi

I have deployed a kong control plane with postgres DB (using helm and working fine) and I want to use kong ingress controller deployment to be in sync with the CP.

Im using the following values.yaml for controller:

image:
  repository: kong
  tag: "2.4.1"

env:
  prefix: /kong_prefix/
  database: "off"
  role: data_plane
  cluster_control_plane: kongcontrolplane-kong-cluster.kong.svc.cluster.local:8005
  lua_ssl_trusted_certificate: /etc/secrets/kong-cluster-cert/tls.crt
  cluster_cert: /etc/secrets/kong-cluster-cert/tls.crt
  cluster_cert_key: /etc/secrets/kong-cluster-cert/tls.key

secretVolumes:
- kong-cluster-cert

ingressController:
  enabled: true
  installCRDs: false
  image:
    repository: kong/kubernetes-ingress-controller
    tag: "1.3.0"

  env:
    kong_admin_tls_skip_verify: true
    kong-admin-url: http://kongcontrolplane-kong-admin.kong.svc.cluster.local:8444

In controller logs I see the following error:
time=“2021-06-14T13:36:20Z” level=info msg=“retry 4 to fetch metadata from kong: making HTTP request: Get “https://localhost:8444/”: dial tcp 127.0.0.1:8444: connect: connection refused”

events logs: Readiness probe failed: Get “http://10.1.3.86:10254/healthz”: dial tcp 10.1.3.86:10254: connect: connection refused

Any help or sample values file would be appreciated.
