Kong Ingress not routing requests to the application service in the EKS cluster

Hi,

We have deployed a notary server on the EKS cluster for docker image signing.
We are able to connect to the application when port-forwarding to localhost (both, via pod and service).

however, when we are sending DCT(docker content trust commands) via the kong ingress, we receive a http 400 error.

Here is the kong proxy logs:
10.92.112.226 - - [07/Jan/2022:14:21:42 +0000] “GET /v2/xxxxx/xxxxxx/notary-server/notary-mariadb/_trust/tuf/timestamp.json HTTP/1.1” 400 59 “-” “Docker-Client/20.10.7 (darwin)”
10.92.99.93 - - [07/Jan/2022:14:21:43 +0000] “GET /v2/xxxxxxx/xxxxxx/notary-server/notary-mariadb/_trust/tuf/root.json HTTP/1.1” 400 59 “-” “Docker-Client/20.10.7 (darwin)”

Here is how we have created an ingress resource:


apiVersion: extensions/v1beta1
kind: Ingress
metadata:
labels:
appkubernetesio/instance: notary
appkubernetesio/managed-by: Helm
appkubernetesio/name: notary-server-deploy
helm.sh/chart: notary-0.0.9
annotations:
kubernetes.io/ingress.class: kong
configuration.konghq.com: ingress-api
name: notary
namespace: notary
spec:
tls:

  • hosts:
    • xxxxxxxxxx
      secretName: xxxxxxxxx
      rules:
  • host: xxxxxxxxx
    http:
    paths:
    • backend:
      serviceName: notary-server-svc
      servicePort: 4443
      path: /
      pathType: Prefix

apiVersion: configuration.konghq.com/v1
kind: KongIngress
metadata:
name: notary
proxy:
protocol: http
labels:
app: notary
route:
methods:

  • POST
  • GET
  • PUT
  • DELETE
  • PATCH
  • OPTIONS
    preserve_host: true
    https_redirect_status_code: 302
    protocols:
  • https
    regex_priority: 0
    strip_path: true

DNS name(host) in the above ingress file points to elb (internal-xxxxxxxxxx.us-east-1.elb.amazonaws.com)

Any help is highly appreciated.
