cd ingress-test
openssl req -x509 -nodes -days 300 -newkey rsa:2048 -keyout ingress.key -out ingress.crt -subj "/CN=ingress.external/O=security"

2 - Create k8s TLS based secret

kubectl create secret tls tls-cert --key ingress.key --cert ingress.crt

kubectl get secret tls-cert -o yaml

  annotations:
     nginx.ingress.kubernetes.io/rewrite-target: /

  tls:
  - hosts:
      - ingress.external
    secretName: tls-cert
  rules:

        path: "/"
        backend:
          service:
            name: svc
            port:
              number: 80

kubectl apply -f ingress-tls.yaml
