I have the following Ingress configuration:

apiVersion: networking.k8s.io/v1        
kind: Ingress
metadata:
  name: http-ingress
spec:
  rules:
  - host: example-adress.com
    http:
      paths:
        - path: /apple
          pathType: Prefix
          backend:
            service:
                name: apple-service
                port: 
                  number: 80
        - path: /banana
          pathType: Prefix
          backend:
            service:
                name: banana-service
                port: 
                  number: 80
  tls: 
    - hosts: 
        - example-adress.com
      secretName: testsecret-tls

And i also created the Secret:

apiVersion: v1
kind: Secret
metadata:
  name: testsecret-tls
  namespace: default
data:
  tls.crt: path to .crt
  tls.key: Zpath to .key
type: kubernetes.io/tls

But when i connect to one of my services and check the certificate it says that it uses a cert created by Kubernetes Ingress Controller Fake certificate. When i run microk8s kubectl describe ingress i get the following output:

Name:             http-ingress
Namespace:        default
Address:          127.0.0.1
Default backend:  default-http-backend:80 (<error: endpoints "default-http-backend" not found>)
TLS:
 testsecret-tls terminates example-adress.com

 Normal  UPDATE  20m (x2 over 28m)  nginx-ingress-controller  Ingress default/http-ingress

What do i need to change to make my Ingress use my Cert instead of generating a new one everytime?
