I want to enable https connections for my application in Google Cloud. I followed several tutorials, yet nothing seems to work.

I've deployed application on GKE using Ingress. Here is ingress.yml:

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: myapp-ingress
  annotations:
    kubernetes.io/ingress.global-static-ip-name: myapp-ip
spec:
  backend:
    serviceName: myapp-service
    servicePort: 80

Accessing it with ip address works just fine, site is accessible from the internet.

I've purchased the domain with Google domains and configured DNS Zones by adding A record pointing to my external IP address and CNAME record. Now app is perfectly accessible with this domain.

Then I created SSL certificate and Kubernate secret by running commands:

openssl genrsa -out myapp-ingress-1.key 2048
openssl req -new -key myapp-ingress-1.key -out myapp-ingress-1.csr -subj "/CN=myapp.co.uk"
openssl x509 -req -days 365 -in myapp-ingress-1.csr -signkey myapp-ingress-1.key -out myapp-ingress-1.crt
kubectl create secret tls myapp-tls-secret-1 --cert myapp-ingress-1.crt --key myapp-ingress-1.key

And updated ingress.yml:

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: myapp-ingress
  annotations:
    kubernetes.io/ingress.global-static-ip-name: myapp-ip
spec:
  tls:
  - secretName: myapp-tls-secret-1
  rules:
  - host: myapp.co.uk
    http:
      paths:
      - backend:
          serviceName: myapp-service
          servicePort: 80

I tried several ingress.yml files following different examples on internet, but none of them worked.

Can anyone advice me?
